The Boy Inventors’ Electric Hydroaeroplane.




CHAPTER I.

A NEW FRIEND MADE.


“Are either Mr. Chadwick or Mr. Jesson about?”

“Humph!” and the gangling, rather disagreeable-looking youth who had
answered the summons to the door of the Boy Inventors’ workshop, gave a
supercilious look over the dusty and worn, although carefully mended,
clothes of the dark-eyed, dark-haired, slender youth who confronted him.

“What do you want to know that for, anyhow?” and upon the personal
pronoun he placed a contemptuous emphasis.

“That is a question to which I can only reply when I can see either
Jack Chadwick or Tom Jesson personally. My name is Ned Nevins,--not
that either of them knows me,--but will you be so kind as to find out
if they’ll see me?”

“If you can’t tell me your business, you can’t see them. State what you
want to me. If it’s money----”

“It is not!”

The dark-eyed young visitor’s eyes held a warning flash which the other
lad, who was half a head taller and far stouter of build than Ned
Nevins, affected not to notice.

“Well, you can’t speak to them.” This with an air of finality.

“But you don’t understand----”

“I do, perfectly. They are both far too busy to bother with any
inquisitive kind of tramp that happens along.”

“Then you won’t let them know I would like to see them?”

The other’s voice rose angrily.

“I said ‘No’ once. N-O-_no_! Isn’t that enough?”

“Quite enough.”

Ned Nevins turned away. As he did so, the other lad, an employee of
the Boy Inventors, and a former school chum, noticed that he had under
his arm a box which he appeared to handle with unusual care. But Sam
Hinkley noted also Ned’s dejected and downcast air. He decided to
humiliate him still further.

“Get a move on--you. Skip!”

Ned hastened his pace. He felt too disappointed and tired to retort
to the bully as he should have done. Sam Hinkley interpreted this
as cowardice on Ned’s part, and being a natural bully he decided to
improve the occasion according to his own delight. He came up behind
Ned and gave the slightly-built lad a strong shove.

Ned faced ’round, and his pale face flushed an angry crimson.

“Don’t do that again, please!”

Young Hinkley’s rejoinder was to make a rush at him. He extended both
his hands to shove the visitor, whom he had found so unwelcome, off the
premises. But the next instant he met with a setback. Still holding his
precious box under one arm, Ned’s fingers closed on the bully’s wrists.
They shut down with a grip like steel handcuffs.

“Ow! Ouch! Leggo my hands,” roared Sam at the top of his voice.

“From what I’ve heard of Jack Chadwick and Tom Jesson I don’t believe
they would tolerate for an instant the way you have behaved toward me,”
was the firm reply. “March!”

“Where are we going?” inquired Sam, writhing painfully under the young
stranger’s powerful grip, unable to do anything, try as he would to
shake it off.

“Straight into that workshop. From what I can hear, I believe we will
find those whom I wish to see inside.”

Sam looked very uncomfortable. He was the son of fairly well-to-do
parents in the little town of Nestorville, on the outskirts of which
Mr. Chadwick’s home was situated. Jack and Tom had taken him on because
he was a youth who had always shown mechanical ability and had pleaded
persistently for a chance to work in the big experimental shop at High
Towers.

But a fair trial of Sam Hinkley had not resulted in his rising in favor
with his young employers. He had been detected in several mean acts.
Besides, they felt he was hardly a lad to be trusted with the important
secrets of the workshop, in which most of the inventions of the boys
and their father and uncle were worked out. So that had Sam but known
it, he was by no means so important a factor at High Towers as he
imagined.

“Lemmo go and I’ll take you in,” howled Sam.

“Very well. You might have done so in the first place.”

But no sooner were Sam’s hands released than he aimed a savage blow at
young Nevins.

“I’ll trim you for this, you--you scarecrow, you!” he bawled out. “I’ll
fix you. I’ll----”

“Here, here! What’s all the trouble about?”

The question was asked by a tall, well-built youth with curly dark hair
and sparkling, intelligent eyes, who had just appeared at the door of
the workshop.

“I--I wanted to find Mr. Chadwick, Jr.,” began the newcomer, while Sam
looked abashed.

“Sure you weren’t looking for trouble?” asked Jack, but a twinkle in
his eyes belied the implied reproach in the question. He knew Sam
Hinkley from the soles of his shoes up. Besides, he had witnessed the
last part of the recent scene and realized how the land lay.

“Go back on your job,” he ordered Sam brusquely, “those bolts must be
ready by noon at the latest.”

“Bu-bu-but----” began Sam, and then, reading what he saw in Jack’s eye
aright, he obeyed, but not without a backward glance at Ned Nevins.

“Why--why, you are Jack--I mean Mister----”

“That’s all right,” was the smiling response, “I am Jack Chadwick. What
did you wish to see me about?”

“Principally about getting a job. I----”

“I’m afraid there’s nothing here for you,” was the reply, as Jack
glanced with interest at the intelligent face that gazed so eagerly
into his own, and then, as he saw the travel-stained lad’s countenance
fall he added, “You see this is an experimental shop mainly, and----”

“I know. I’ve heard all about your inventions, the Sky-ship and the
diving Torpedo Boat and so on. I love mechanics and I’m sure I could
make good if you’d give me a chance.”

“What is your name?”

“Nevins is my name, sir.”

“Ever had any experience along such lines?”

“Yes, sir, my uncle was an inventor. He was poor and worked in a
machine-shop, but when he was at home he and I used to spend all our
time in a workshop he had fitted up. You see my folks died a long time
ago and I was brought up in my uncle’s home. He said that some day
I’d be famous if I worked hard and that I had a natural ability for
mechanics and----”

Ned Nevins stopped short, flushed over what he felt had been a
conceited speech. But Jack glanced at him encouragingly. The young
inventor was quick to read character. He began to take an interest in
this ragged visitor, who had dropped down out of the skies, so to speak.

“But you are not living with your uncle now, Nevins?”

“Oh, no. He was killed a month or more ago in an accident in the
mills. My aunt didn’t want me ’round the house; no more did my cousin.
So I packed up what I had; it wasn’t much,” with a rueful smile,
“and--and----”

“Set out to seek your fortune. So far, if you don’t mind my saying it,
you don’t appear to have succeeded very well. And so you want a job.
How have you been making your way?”

“Doing odd jobs for farmers and so on. I’m clever at repairing
automobile machinery, and I earned a little that way. You see, my
object was to make my way here, otherwise I might have got two or three
jobs in garages or machine shops.”

“Why were you so anxious to come here?” demanded Jack, beginning to
feel an interest in this persistent youngster.

“Because of a strange legacy my uncle left me.”

“That’s an odd reason.”

“I know it; but may I explain?”

“Surely. Go ahead.”

“Well, it was a legacy that he said would bring me fame and fortune
some day. It may have been only an inventor’s dream. My poor uncle had
many such, or it may not be all that he thought of it. There were many
reasons why I couldn’t consult any one in my own town about it, and as
I’d read of you and felt I could trust you and your advice, I sought
you out. But if the invention, for that’s what the legacy was, is worth
anything or not, I want a job.”

“Come on inside, Nevins. You seem to have the right stuff in you. We’ll
have a talk.”

And with a wide-eyed youth behind him, Jack led the way into the
workshop. Sam Hinkley viewed his young employer and the latter’s
companion with marked disfavor from his work bench.

“Wormed your way into the place already, have you?” he muttered. “I’ll
keep my eye on you, young fellow, and don’t you forget it.”




CHAPTER II.

AN INVENTION DESCRIBED.


Ned Nevins had told nothing but the simple truth when he stated that
he had endured many hardships and much rough travel under unpleasant
conditions in order to obtain an interview with the Boy Inventors.

He was a boy of singularly firm character and persistency or he would
never have triumphed over the obstacles he had conquered in order to
gain his ambition. When Ned’s uncle, Jeptha Nevins, had died, he had
entrusted to the boy the tin box which we have seen Ned guarding with
so much care. It contained plans and specifications of an invention
upon which the elder Nevins had spent all his spare time for many years.

Whether the invention was a practical one or not, Ned, skillful as he
was in the line of mechanics, did not know. But his uncle’s faith in
the value of his invention was so great that he had inspired his nephew
with almost implicit confidence in the soundness of his judgment.

Ned might have stayed in his home town and awaited a more favorable
opportunity for setting out on his travels but for one thing. Jeptha
Nevins had a son, a hulking ne’er-do-well sort of lad, or rather young
man, for he was some years the senior of Ned, who was sixteen.

Following his father’s death, “Hank” Nevins, as he was known among
his cronies, made a big fuss when he learned that Ned had been left
the plans of Jeptha Nevins’ invention. There was little else but the
furniture in the house and a small sum of money in the savings bank;
and so Hank Nevins laid formal claim to the plans of the invention from
which Jeptha Nevins had hoped so much.

But Ned refused absolutely to give them up to Hank. With almost his
dying words, Jeptha Nevins had entrusted the plans to his nephew, for
he had long since given up hopes of making anything out of Hank. In
fact Ned knew that it had been his uncle’s wish that Hank should know
nothing of the invention, but in some way the latter had discovered the
fact of its existence, and he hoped, that by selling it, (provided it
was in any way practical,) he might obtain some money which he could
expend in dissipation.

When he found that Ned was unwilling, or rather refused absolutely, to
give up the plans, Hank had flung out of the house with all manner of
threats, among them being that he would force his cousin to give up the
coveted plans by process of law. Ned knew nothing of law and like many
persons similarly situated, the idea of Hank’s resorting to lawyers to
obtain possession of the plans alarmed him. Among Hank’s acquaintances
was a young law clerk of “sporty” proclivities. With the aid of this
young limb of the law, Hank had succeeded in thoroughly alarming
Ned as to the legality of his retention of the papers. Matters were
constituted thus when Ned determined not to risk the possession of his
uncle’s plans any longer but to leave the small cottage, where they all
lived, and seek counsel and aid elsewhere than in his native village.

From the first time he had read of them, the Boy Inventors had
possessed a large place in Ned’s mind. In his extremity, therefore, he
had decided to seek them out and try to interest them in the untried
invention.

“Sit down,” said Jack, when the two boys were inside a small room
at one end of the workshop which, for lack of a better word, was
called the office. It was a very business-like looking room. Books on
technical topics lined the shelves at one end of it. Models, samples of
materials, test-tubes and other apparatus occupied most of the rest of
the available space.

Under the book shelves, however, was a desk. It was to one of the
chairs standing beside this latter piece of furniture that Jack
motioned his odd guest.

Ned sank into the chair with an alacrity that made it plain that he was
tired. He had, in fact, come some miles from his last stopping place
that morning.

“I’m sorry that you had that trouble with Sam Hinkley,” began Jack in a
kindly tone, “he should have known better than to treat you as he did.”

“Oh, that’s all right,” the other assured him hastily, “I’d have stood
for a lot more than that in order to get a chance to see you and tell
you what I’ve traveled a good way to say.”

“You said you had an invention, I think.”

“Yes; but it is not, properly speaking, mine,” and then Ned Nevins went
on briefly to describe the circumstances by which he had come into
possession of the plans in which both he and his uncle set so much
store. But up to this point he had not mentioned the nature of the
invention and Jack brought him to the point by a question.

“And just what may this invention be?”

Ned Nevins hesitated a few seconds before replying.

“I hardly know just what to call it,” he said, “but I guess an electric
hydroaeroplane about describes it.”

Jack’s face betrayed his interest.

“You mean a craft capable of air and water travel that is driven by
electricity?” he asked.

“That’s just it. But there are many novel features about it, however.
My uncle set most store by one particular novelty in its construction,
and that was the fact that it was driven by electricity instead
of gasolene. Gasolene is bulky, dangerous and heavy to carry, and
sometimes hard to obtain, but by using an electric generator, worked
while the machine is in motion, the Nevins hydroaeroplane, as my uncle
called it, has plenty of cheap power always obtainable and is simpler
than gasolene-driven motors in a number of ways.”

“But about your storage batteries--I suppose that’s the idea?”

Ned Nevins nodded.

“That’s just the point I was coming to,” he said; “one of the most
notable features of the Nevins hydroaeroplane is the fact that its
power is furnished by storage batteries many times lighter than any yet
constructed, and capable of developing many times the power. But the
plans will show you all that far better than I can explain.”

“I should like to see them.”

Although he was interested and showed it, Jack Chadwick had seen far
too many impracticable inventions to wax enthusiastic over any scheme
till he had examined into it for himself. But he knew that if young
Nevins had what he said he had, he was in possession of a big thing.

So it was with considerable expectancy that he watched young Nevins
fumble with the lock of the battered tin case. Finally he opened the
receptacle and drew out a roll of papers. These proved to be blue
prints, and closely penned writings covering several foolscap sheets.

Naturally, Jack’s attention was first directed to the blue prints that
young Nevins eagerly spread out on the table before him. Accustomed as
he was to such things, he read the intricate lines and tracings almost
as plainly as print.




CHAPTER III.

AN IMPORTANT DECISION.


“Well, what do you think of it?”

Ned asked the question with almost pitiful eagerness. His tone clearly
betrayed how much the answer meant to him.

“I think that the idea appears feasible, but of course, I can’t say
anything definite yet,” was Jack’s rejoinder. “I will have to consult
with my cousin, Tom Jesson----”

Ned nodded that he had heard of young Jesson, who had had so much to do
with the Boy Inventors’ work.

“And after we have gone over the plans together we can tell you just
what we think of it. Suppose that the idea appears to be possible to
work out, what would your plans be?”

“That we each take an equal chance in the profits that may come from
it,” replied Ned in quick, certain tones that showed he had thought the
matter out all clearly in his own mind.

“Well, that would come later. You would be clearly entitled to more
than a third share, for the invention practically belongs to you.”

“Yes, but I have no capital to put into its manufacture. My idea was
that you would build the craft, with me to help, for I know my uncle’s
ideas in regard to the craft backward, almost.”

Jack smiled.

“I see you have every detail figured out.”

“If you knew how much I have thought of it!” exclaimed Ned.

“I can well imagine that. Well, Ned, I can promise you one thing--if
the invention offers any possibility of success we will undertake it.
We have nothing on hand just now and this is surely a big idea you have
brought us.”

“I believe in it,” declared the boy fervently.

“Well, that’s half the battle. Suppose you come and see us to-morrow
morning. We will go over the plans to-night and see what we think of
them. By the way, where are you staying?”

“Nowhere just at present. I came straight up here as soon as I arrived
in Nestorville.”

“You must have been eager to see us.”

“I was, indeed. I had traveled a good many miles to do so, as I
explained.”

“Well, Sam Hinkley’s father keeps a sort of hotel in Nestorville. It is
cheaper than a regular first-class place but I think you will find it
comfortable.”

“Anything will suit me. I shan’t sleep much to-night, anyhow,” replied
Ned, taking no notice of the name that Jack had mentioned.

“Don’t build too many hopes, Ned. I should hate to have to disappoint
you.”

The boys shook hands and parted. Jack watched the dusty figure of Ned
Nevins as the boy wended his way down the hill.

“There goes a boy with the right stuff in him,” he said to himself.
Although he was young in years, Jack Chadwick was ripe in experience,
as those of our readers who have followed the adventures of the Boy
Inventors through the various volumes know.

For the benefit of those who are making their first acquaintance with
the two lads, we will briefly relate the careers of Jack Chadwick and
Tom Jesson, his cousin, up to the time that we resume our friendship
with them in the present book.

Jack Chadwick’s father was the famous Professor Chadwick, whose various
inventions had made him well-to-do, and who was known throughout
the civilized world. The Chadwick method of steel reduction and the
same inventor’s ingenious devices for rock boring and drilling came
to the notice of the general public during the construction of the
Panama Canal. But Professor Chadwick had to his credit a host of other
inventions which, if not quite so well known to the world at large,
none the less played a large part in the history of civilization.

The Professor, whose wife had died soon after Jack’s birth and before
fame came to him, had purchased the estate of High Towers, lying a
short distance from the pretty little town of Nestorville as a secluded
place in which to carry on his researches. Not long after he had
acquired it, Mr. Jasper Jesson, his brother-in-law and a well-known
explorer and biologist, was reported missing while on an expedition in
the tropics. As Mr. Jesson was also a widower, the care of young Tom
Jesson, the explorer’s only child, devolved upon Prof. Chadwick.

Jack Chadwick and Tom Jesson had thus practically grown up together
and were more like brothers than cousins. As time went on, both lads
developed a strong liking for pursuits similar to the Professor’s,
and when still a young boy, Jack had invented a patent churn, which
came into wide use, as well as improving many household devices.
The Professor was delighted with the skill and adaptability of both
boys, and aided them all he could in their chosen pursuits. They both
took technical courses at a school in Boston, not far from which city
Nestorville was situated.

Aeronautics before long began to engage their attention to the
exclusion of every other study. Professor Chadwick, too, was interested
in this topic, which was developed at High Towers, together with some
experiments in an improved wireless plant.

In the first volume of this series, “The Boy Inventors’ Wireless
Triumph,” we saw how the boys’ hard work bore fruit in an adventurous
voyage to Yucatan. They participated in many thrilling adventures and
dangerous experiences which culminated in the finding of Tom Jesson’s
long missing father.

The next volume showed the boys in a new field of endeavor. There is
brotherhood among inventors, and when a friend of Mr. Chadwick’s, who
was perplexed by problems connected with a new sort of gun, came to
them they were glad to aid him in any way they could.

This work involved them in a surprising series of experiences, not all
of which were pleasant. In fact, at times, every ounce of resource,
courage and perseverance, which both lads possessed to a high degree,
was called into requisition to bring them out of their difficulties.
This volume was called “The Boy Inventors’ Vanishing Gun,” and related,
in considerable detail, the final triumphant outcome of the trials and
tribulations which had beset the youthful mechanics.

In the third book dealing with our young friends, we found them
essaying triumphs in a new element. This volume was called “The
Boy Inventors’ Diving Torpedo Boat.” The boat was a masterpiece of
mechanical construction and a long cruise the boys took in her under
the surface of the waves provided a narrative of surpassing interest
and gripping power. By the aid of their submarine torpedo boat the boys
were enabled to play an important part in succoring some beleaguered
Americans, who were in peril of their lives at the hands of a band of
bloodthirsty Cuban revolutionists. The boys were put to a hard test
during this period of their lives, but after all, their experiences
endowed them with increased self-reliance and manliness which was to
prove of inestimable benefit to them later on, when these qualities
brought them successfully through adventures and trials more rigorous
than any they had yet faced.

A Flying Ship was their next craft and in her the boys ventured on a
unique quest through the untrodden regions of the Upper Amazon. An odd
German professor was their companion and mentor. This was Professor
Bismarck Von Dinkelspeil, who was as kind-hearted as he was eccentric.
Professor Von Dinkelspeil was in search of an extraordinary inhabitant
of the remote Brazilian jungles. The boys met him in a strange
way and were enabled to offer him much assistance. Dick Donovan, a
lively young reporter, and Captain Abe Sprowl, a rough-and-ready New
England skipper, were others of their companions on what proved a
unique cruise, the details of which were fully set forth in the volume
immediately preceding the present, which was called “The Boy Inventors’
Flying Ship.”

Naturally interested in aeronautics as they were then, the two lads
went into “executive session” over the plans of Ned Nevins’ electrical
hydroaeroplane as soon as Tom Jesson returned from Boston, which was
late that afternoon. He had gone to the city to order some materials
needed in a new landing device the boys were working on. Far into
the night the two boys pored over the plans, waxing more and more
enthusiastic as they progressed.

“It seems to me that this craft is as practical and as possible to
construct as an electric roadster,” declared Jack, as they concluded
their labors.

“To build, yes, but how about it working when it is built?” said Tom
Jesson, who was less of an idealist than his enthusiastic cousin.

“Are you willing to try it, Tom?”

“I am, yes. How about you?”

“I’m confident enough of success to risk some of the money we made out
of that Yucatan treasure chest.”

“Then I’ll contribute my share, too. When do we start?”

“Nothing to hinder us getting on the job right away. This is too big
a thing to keep waiting. We’ll send for Ned Nevins first thing in the
morning. If this invention turns out half as well as it looks, his
legacy will make him famous as well as relieve him from want.”

Possibly, if the boys could have looked into the future, Jack would not
have spoken so confidently. Troubles they never dreamed of lay ahead of
them, and, at that, in the near future.




CHAPTER IV.

NED TO THE RESCUE.


In the meantime, Ned Nevins had retraced his steps to Nestorville.
It was a pleasant little village, with neat, white houses lining its
elm-bordered streets, each with its trim lawn and flower beds. To the
boy who had been wandering in the dusty roads so long, it appeared
wonderfully homelike and pleasant, although his travel-stained garments
looked doubly distasteful to him in the midst of so much neatness and
unobtrusive prosperity.

He passed the main hotel of the place and continued down High Street
till he came to a rather less pretentious-looking place, bearing over
its door the name, “The Hinkley House.” It was not until then that
Ned suddenly recollected that Hinkley was the name by which Jack had
referred to the disagreeable youth up at the workshop.

“Wonder if he’s any relation?” thought Ned to himself as he ascended
the steps and entered the office.

A man with bristly red hair, and a not over-pleasant expression of
countenance, stood behind the desk writing in a big book.

“Well, boy?” he asked sharply, as Ned entered the place. “If you’re
selling anything we don’t want nothing.”

And then he resumed his writing without taking any more notice of Ned,
who eyed him rather amusedly for a few seconds. Then he addressed him
in a pleasant tone.

“I should like to get a room here, please.”

“Humph!” the red-haired man looked up with a grunt rather suggestive of
a certain barnyard animal. “A room, did you say?”

“Yes, sir. An inexpensive one. In fact, as cheap a one as you have.”

“Sure _you_ can pay for it?” was the uncompromising reply.

“I certainly can or I shouldn’t have asked you for it,” said Ned, with
the same flash in his eyes as had come there when Sam Hinkley had
addressed him so rudely that morning.

Apparently the landlord of the Hinkley House concluded that he had gone
far enough, for in a more amiable tone he said:

“I can let you have a good room for a dollar. Want your meals?”

“For to-day anyway,” responded Ned, who had saved from his garage work
along the road enough to make him feel sure of himself for a short
time, anyhow.

The business was soon concluded and Ned was at liberty to go up to
his room. As soon as he was alone, he drew a chair to the window and
sat there thinking deeply. Naturally his thoughts all reverted to one
subject, and that was: what would be the verdict at High Towers?

“If they only knew how much depended upon it,” thought the boy to
himself, and then his fancy roamed back to that final scene when he
had looked on his uncle for the last time and had received what to
him was almost a sacred trust. From this his thoughts turned to his
ne’er-do-well cousin and the latter’s threats. His uncle had left no
will and Ned was not quite certain in his own mind if he had any legal
rights to the papers dealing with the electric hydroaeroplane.

“If they were to find out where I had come, they might try to make it
unpleasant for me,” he thought with a momentary qualm, but the next
moment he put these thoughts aside, and when he descended to dinner he
was in a cheerful, hopeful frame of mind.

Mine host Hinkley’s meals were not of the sort that could be described
as Lucullan, but they were solid, and Ned ate with the hearty appetite
of a growing boy. After he had finished, he decided to saunter out and
see what he could of the town. It would at least help to pass away the
time till the next day, upon which he felt his fate hung. For the life
of him he could not have settled down to read or write till he knew
definitely what the verdict upon his unique legacy was to be.

In this frame of mind he wandered through the main street of the little
town, which did not take very long, and soon found himself out upon
the high road. The road was a pleasant winding one, and Ned walked on
briskly, turning over in his mind, as he went, the many events that
had recently transpired to work such a change in his career. He could
not help an exultant leap of the heart as he thought of the possible
outcome of a favorable opinion of the dead inventor’s great lifework.

He was still revolving this thought in his mind when, on rounding a
turn in the winding road, he came across a sight which temporarily put
all other thoughts aside.

Stalled in the center of the road was a fine looking automobile. Ned,
who, as we know, knew a lot about cars, recognized it as a machine of
expensive make and as an imported car. Bent over the engine was a man
who appeared to be trying to adjust whatever was the matter with the
motor. Standing about were two other men. As Ned came up, one of them
turned to him.

“Here, boy, do you know if there’s a garage in Nestorville?”

Now, Ned knew that there was not, for he had looked about for one,
thinking that if his mission at High Towers failed, he might chance
to get employment in such a place till he got money enough to find a
better job. So he replied in the negative.

The man, who wore auto goggles, and was big and broad, turned to his
companion with a gesture of annoyance.

“Too bad, Smithers,” he said in a vexed tone, “if Elmer there can’t
fix that motor we’ll have to leave the car here and telephone into
Boston for another.”

The chauffeur straightened up from his labors over the refractory motor.

“I’m afraid we’re stuck, sir,” he said, “this car is a Dolores. If it
was any American car now, I could----”

“Never mind that,” interrupted the big man, with an impatient gesture.
“I hired you as a competent chauffeur and now the first break-down we
have----”

“If it was an American car,” protested the man. “I don’t understand
these Dolores and----”

“Maybe I can help you.”

It was Ned who spoke and the big man faced round on him in surprise.

“You!” he exclaimed. “What do you know about cars?”

“A little, sir.”

“Well, at any rate you can’t know less than Elmer,” said the big
man with a disgusted look at his chauffeur, who looked downcast and
abashed. “What do you want to do?”

“See if I can get your car going for you. I’m interested in this sort
of thing, you know.”

“Umph! don’t look as if you owned a car,” commented the man who had
been addressed as “Smithers.”

“That’ll do, Smithers,” spoke up the big man sharply. “Elmer owns that
he’s up against it, so give the boy a chance to show what he can do.”

In one garage where he had worked for a time the “big man of the place”
had owned, as it so happened, a Dolores car. Therefore Ned was not at
sea when, in the overalls he had borrowed from the chauffeur, he set to
work on the stubborn motor.

“Think you can fix it?” asked the big man, after Ned had requested the
chauffeur to start the engine so that he could hear just what was the
matter with it.

“I don’t know,” said Ned frankly. “It’s missing in two cylinders.
Carburetor trouble, I think. The Dolores has a special make of
carburetor, you know, a very sensitive and complicated variety.”

“Go to it, kid,” muttered the chauffeur. “If you can fix that mixed-up
muss of springs and air-valves you’re a wonder.”

“If you’ll slow down the engine a while, I’ll try,” said Ned,
determined to do his best. It was characteristic of him that he was as
interested in this vagrant bit of roadside trouble that had come his
way as he would have been in some problem directly concerning himself.
As it so happened, however, the problem he was about to try to solve
did concern him and, at that, in no very distant manner.

Of this, however, he was not to become aware till later, and then
in a manner which startled and rather alarmed him, considering the
consequences it involved. But in blissful ignorance of all this, Ned
went to work, determined to do all in his power to convince the two
rather sceptical autoists that he was not boasting when he had said he
thought he could help them out of their difficulties.




CHAPTER V.

THE UNLUCKY STORY.


“Once more--that’s it!”

Ned suspended his labors for a moment and listened to the tune of
the throbbing motor as the chauffeur started it up, following Ned’s
adjustment of the carburetor.

“It’s working better already,” declared the big man. “Boy, you’re a
wizard.”

Ned looked up smilingly. In the interest of the work, and the
fascination he always felt in conquering the whims of a stubborn bit
of machinery, he had quite forgotten for the moment all his trials and
perplexities.

“I think I’m getting there all right,” he said confidently, “but it
will take a little more time to fix it just right.”

“Ah! You believe in doing things thoroughly, I see.”

“I do, sir. Whatever is worth doing is worth doing well.”

“That’s a belief that will get you a long way in life, my boy,” said
the big man. Ned hardly heard him, for the motor was once more roaring
and pulsing. He tuned it up, listening to its explosions as a skilled
musician might hearken critically to a piece of music.

As he listened, he tightened up a connection here or loosened a valve
there till the big six-cylindered motor was humming with the even
pulsations of a sleeping baby.

“You can shut her off,” said he, addressing the chauffeur, and then
turning to the big man he added, “I think you’ll find no more trouble,
sir.”

“What! You have adjusted it, my boy?”

“As well as I can, sir, and, without bragging, I guess you’ll find
everything all right now.”

“How long will it remain so?” asked the sceptical Smithers.

“For several weeks, at any rate.”   “You may take the wheel again,
Elmer, and hustle us along. Young man, that you’re a mechanic of no
mean ability I could see by the way you went to work. What is your
name?”

“Ned Nevins, sir.”

“Live here?”

“I do just now, but I come from Millville, N. Y.”

The big man looked surprised.

“Are you any relation to Jeptha Nevins?”

“His nephew, sir. Did you know him?”

“Very well. I am Vaughn Kessler, the owner of the Kessler Mill. Your
uncle was my foreman for many years. He was one of the best men we ever
had; I was very sorry to hear of his death. Is there anything I can do
for you?”

“No, thank you, sir, except----”

“Except what? Come, you’ll pardon my saying so, but you don’t
look--well, very prosperous.”

“I am all right, thank you, sir, and have good prospects ahead of me,”
replied Ned. “What I was going to ask you was not to mention my name in
Millville or to say where you saw me if by any chance anyone should ask
you.”

“But why? You are not under a cloud there surely, and if----”

“Oh, no sir! It is for quite another reason,” said Ned earnestly.

“Well, it shall be as you wish,” said Mr. Kessler, regarding the boy
with some curiosity, “though why in the world you should make the
request puzzles me. Good-bye, my boy, and thank you.”

He held out his hand and took Ned’s. The next minute the car that the
boy had so cleverly placed back in running order moved swiftly off.
As it receded along the road, Ned became conscious that there was
something in his hand. It had been left by Mr. Kessler.

“It’s money!” exclaimed the boy, unclasping his fist. “Well, it won’t
come amiss, although I wouldn’t have thought of charging him for that
little job.”

He unfolded the bill and then gave a little cry of astonishment. It was
for twenty dollars,--a small fortune to Ned.

“Well, I am in luck!” he exclaimed. “If only my fortunes have changed,
as this seems to indicate, I’ll be lucky to-morrow as well, and that is
the dearest wish of my heart.”

It was well for Ned’s peace of mind that he did not know that Mr.
Kessler, while fully intending to keep his promise of not mentioning
Ned’s name or address at home in Millville, unconsciously let the cat
out of the bag when he arrived at Lowell, Mass., his destination.
His important interests, and those of his traveling companion, Mr.
Smithers, made him a big man there and the late arrival of his
automobile, which kept a momentous meeting waiting, called for
explanations. To the newspaper men of Lowell, Mr. Kessler told how
he had been aided by a shabbily clothed boy on a country road when a
trained chauffeur had failed to adjust his car. It made an interesting
story, and was telegraphed over the country by a correspondent of a
news association. In due course it appeared in the Millville papers
under this heading:

  MILLVILLE MAGNATE AIDED
  BY A LAD FROM THIS CITY.

  Vaughn Kessler’s Stalled Auto Started
  By Ned Nevins, Motor Genius.

The article beneath these headlines described the whole incident
briefly, and stated that Ned was at present residing in the village of
Nestorville, Mass. With but few exceptions, the fact that Mr. Kessler
was concerned in the story was the chief feature of interest to readers
of the article.

One individual in Millville read it with burning eyes. This was Hank
Nevins, Ned’s cousin. Following Ned’s disappearance, he had used every
means in his power to locate the boy. For this he had a good reason.
Not alone did he want to recover the plans and designs of the electric
hydroaeroplane, but he was prepared to offer a price for them.

While Ned had been making his preparations to depart quietly from home,
Hank, on the advice of his lawyer friend, had visited the head of an
aeroplane manufacturing concern who happened to be visiting Millville.
Hank had laid before the stranger as full a description as he could
of his father’s invention. He left out many important points but the
stranger was quick to see possibilities in the idea and offered Hank a
substantial sum if he would bring him the plans.

The offer aroused all of Hank’s cupidity. He saw a way, as he thought,
to a life of elegant leisure. Only one stumbling block interposed
itself, and that was a seemingly insurmountable one.

Ned had vanished, and with him the papers that would have meant money
to Hank. On the advice of his legal friend, Hank had advertised for Ned
in the personal columns of half a dozen newspapers. But none of the
carefully worded appeals to the boy to reveal himself had borne fruit.
Hank was obliged to confess to Mr. Melville of the Blue Sky Aeroplane
Company that he would be delayed in producing the plans, not admitting
that it would be extremely unlikely that he could ever get possession
of them at all.

“Well, any time you have them bring them to me,” said Mr. Melville
before he left Millville. “And my offer will hold good.”

Hank’s thoughts were not very pleasant ones as he left the aeroplane
man’s presence.

“The young blackguard, to run off like that,” he grumbled. “Those
plans mean dollars and cents now. How can I get them? If I could locate
that runaway brat, I’d soon find a way.”

And now, through that unfortunate article in the _Millville Clarion_,
Ned Nevins’ hiding place had been revealed to the last person on earth
Ned would have wished to have known of it.

That night, as soon as his work was done, Hank sought out his budding
lawyer friend. The law, like all other professions, has its black
sheep. Hank’s friend bade fair to become one of these when he should
ultimately be admitted to practice, which was his ambition. His eyes
glistened when he heard of Hank’s discovery.

“If only we could get those papers,” muttered Hank, as the two sat
together that night. “We’d both have money to burn, Miles.”

Miles Sharkey was the name of Hank’s crony, and the latter part of his
appellation suited him from the ground up. In his projecting yellow
teeth and undershot jaw, as well as in his fishy, shifting eyes, there
was something suggestive of the rapaciousness and treachery of a shark.

“I think I can find a way to make him give them up, Hank,” said Miles,
after some moments spent in deep thought, “but it may take a little
time to work out the details. Have you any idea what he can be doing in
this Nestorville place?”

“Not on the first guess. Just a crazy notion of his, I reckon. But
what’s your plan, Miles.”

“I’ll have to think out the details,” rejoined the redoubtable limb of
the law, rubbing his tallowy hands together. “But I think we’ll be able
to make Cousin Ned disgorge before very long--for a consideration.”

“On the day I get my money, you get yours,” Hank assured him.

“Consider it settled then,” said Miles. “I’d have to be a pretty poor
lawyer if I couldn’t think of a way.”

“I--I’m not particular about law,” blustered Hank, “anything to get
those plans. He’s only a kid, and once we’ve got ’em he can’t do
anything.”

“It’s a great pity you didn’t get hold of them before he skipped out,”
said the worthy Miles. “Anyhow, it’s all right. I’m smart enough to
attend to that.”

“Miles, you’re a true friend.” And as they parted, Hank clasped his
companion’s claw-like hand with a fervor worthy of being bestowed on a
better man.




CHAPTER VI.

HIS ENEMIES ON THE TRAIL.


Ned Nevins walked back to the hotel with his brain in a whirl. In the
first place, the twenty-dollar bill which he fondly fingered as it lay
in his pocket, provided a stop-gap between want and what he hardly
dared to consider, and that was, a refusal on the part of the Boy
Inventors to have anything to do with his cherished plans.

In the second place, his encounter with Vaughn Kessler was a dubious
source of satisfaction to him. From one point of view it had, of
course, its pleasing side, but somehow, Ned could not free himself of
an uneasy feeling that in some way the news of his whereabouts would
get back to Millville. In what a devious way this was to happen he had,
of course, no conception, and it was just as well for his peace of mind
that he had not.

He arrived at the hotel a little time before supper, and having cleaned
himself up as well as possible, and carefully brushed his hair and
his garments, he descended to the porch and sank down into the most
comfortable chair he could find, one commanding a good view of the
street.

A boy came along with papers, and feeling that with his twenty-dollar
bill snugly tucked in his pocket he could afford to indulge in a few
luxuries, Ned bought two papers, one a local sheet, the other a Boston
daily. He looked through the latter first and as his eye traveled down
the columns it was caught by the Personal Column.

In this section of the paper were published notices to missing
relatives and so forth. The type used was large and heavy and
calculated to catch the eye.

What was Ned’s astonishment to suddenly spy his own name at the head of
a notice two or three paragraphs from the top of the list. He stared
at it in some wonder for a minute before he read the notice itself.

“Why, who can be advertising for me?” he thought, and with the thought
came an uncomfortable sensation at the recollection of the legal
processes with which his cousin had threatened him.

“I’ll read the notice, that’s the best way of solving the puzzle,”
reflected the boy. Casting his eye over the paragraph, he read as
follows:

“Ned Nevins: It will be to your advantage to communicate at once with
your cousin at Millville, N. Y. Big opportunity.--H. Nevins.”

“That’s Hank! what sort of a trick is he up to now?” wondered Ned. “To
‘my advantage,’” he musingly went on. “I’d like to know what there is
to ‘my advantage’ that Hank would be likely to take the trouble and
expense to advertise about. ‘Big opportunity’--yes, a ‘big opportunity’
to get his hands on those papers. The idea of his thinking that I’d be
softy enough to answer such an ’ad’! No, indeed, you’ll never locate me
in that way. I’m glad I asked Mr. Kessler to say nothing about having
seen me. Hank is working harder than I thought possible for him to
locate me, but he won’t do it if I can help it.”

Which shows that Ned, like most of the rest of us, placed undue
confidence in his own ability to avoid unpleasantness. We already know
how Fate was at work to over-reach him, playing with what appeared to
be malignant favoritism, into the hands of those who wished him harm.

He was roused from his reverie by the sound of a quick step behind him,
and then a hand was placed none too gently on his shoulder.

“It’s that fresh kid again!” exclaimed a grating, unpleasant voice.
“Get up out of that chair instantly--do you hear me?”

“It’s Sam Hinkley!” exclaimed Ned to himself, without, however, looking
around. Aloud he demanded:

“Well, what do you want?”

“That chair.”

“Unfortunately it is, as you see, occupied.”

“I wish it at once!”

“You do?”

“Yes!”

“You have a cool way of asking for it. Suppose I don’t give it to you?”

“You’ll be made to!”

“Who’ll make me?”

“I will, I guess. You don’t know who I am?”

“Oh, yes, I do. Your name is Sam Hinkley. I had a little argument with
you this morning in which you came out second best, I fancy.”

“I’ll teach you a lesson, you tramp. Are you going to get up?”

“When the supper bell rings, I mean to.”

“Not till then?”

“No thanks, I’m very comfortable where I am.”

“That’s my chair.”

“Indeed, I thought it was one of those placed out here for the benefit
of the guests.”

“So it is.”

“Well, I happen to be one.”

This answer took the blustering Sam rather aback. He thought that Ned
had sought a chance to rest himself at the expense of the hotel’s
hospitality. But it suited his purpose to appear incredulous.

“They don’t take in vagabonds here.”

It was more than flesh and blood could stand. Ned was about to leap to
his feet when he was spared that trouble by the chair being yanked from
under him, and he fell sprawling on the floor of the porch.

“Haw! haw! haw!” bawled Sam, in high good humor at seeing Ned in such
an undignified position.

“Ho! ho! ho!” echoed half a dozen of Sam’s cronies, who had been
passing with him when he had spied Ned, to whom Sam had taken an
instinctive dislike. The “gang” had been invited by Sam to see the
“fun.” If it had not been on the porch of his father’s hotel that Sam
encountered Ned, he would have hesitated to try issues with him, for
his experience of the morning had shown him that Ned, slender and
rather delicate-looking as he was, was a foeman by no means to be
despised. But on home grounds he felt safe.

He was rather taken aback, therefore, when Ned scrambled to his feet
and advanced toward him instead of retreating, as the bully had
expected Ned would do. There was a fire akindle in Ned’s eyes that Sam
by no means liked, for he was at heart a coward, although accustomed to
lording it over other boys of his own age not a little.

But with the eyes of his cronies fixed upon him expectantly, he felt
that he could not retreat.

“What do you want?” he asked, in a voice that he tried to make
belligerent, but which, somehow, did not hold quite the warlike note
he would have liked.

“I want to give you something you need badly,” said Ned, without
raising his voice, but there still glowed that same dangerous light in
his eyes.

“Are you ready?”

“Rer-ready for what?” demanded Sam, in vain trying to look unimpressed
by this quiet, business-like lad with the steady voice.

“For what I fancy is to be your first lesson in manners.”




CHAPTER VII.

NED MAKES AN ENEMY.


A wavering look of indecision crept into Sam Hinkley’s pug-nosed
countenance. He would have liked to have the last few moments over
again. He felt that he would have acted differently. But he tried to
brazen it out.

“You strolling vagabond from goodness knows where, take that!”

It was a vicious blow, with plenty of force behind it, for Sam,
although a bully and not possessed of an overabundance of courage,
was still wiry and well muscled. But to his surprise his blow did not
land. It should have collided with Ned’s chin, but when its force was
expended, Ned was not there.

He had stepped neatly aside and allowed Sam to launch his thunderbolt
harmlessly. Sam’s friends, grouped beneath the veranda on the
sidewalk, closed into a compact little crowd. Plainly Sam was not going
to carry all before him as had been his habit hitherto. His cronies saw
this at once and some of them inwardly rejoiced.

The office of the little hotel was deserted, and nobody interfered. Sam
gathered himself together to renew the combat. His brow grew black. Ned
stood waiting. He made no attempt to defend himself. He merely eyed Sam
Hinkley with a look of contempt that maddened that pugnacious bully.

Sam eyed his opponent viciously.

“Well?” queried Ned.

“Thought you were going to fight!” roared Sam.

“As I told you before, I’m not a fighter.”

Sam rashly interpreted this as being a sign of weakness. He rushed in
once more, swinging his big fists with more vigor than science. Once
more Will-o’-the-Wisp Ned was not where he ought to have been, and Sam,
carried off his feet by the vigor of his unopposed onslaught, collided
with a chair, tripped, and fell headlong on the floor to the porch.

This time the laugh that went up was not at Ned’s expense. The boy
stood in the same quiet attitude while Sam, his face crimson with anger
and mortification, gathered himself up.

“This ain’t fighting!” he bellowed angrily.

“You can call it anything you like--an acrobatic performance if you
wish,” rejoined Ned, without raising his voice or changing his position.

Now there is nothing more irritating than to lose your temper and to
make an exhibition of yourself, while the one your rage is directed at
stands as steady and unmoved as a rock, hardly deigning to reply to
either threats or onslaughts.

Sam was almost beside himself with rage as, with blazing eyes, he made
another dash at Ned. This time Ned did not step aside. He ducked under
Sam’s terrific left, and coming up, struck the bully a blow in the ribs
that caused that worthy to emit a sound resembling:

“Oof!”

Ned took advantage of the momentary pause in hostilities to speak.

“Look here, Hinkley,” said he. “I’m not a ruffian, and I don’t like
fighting. We’ll call this off right here and now, if you say so. I’m
willing--what do you say?”

“That I’m going to give you the licking of your life!” roared out the
enraged Sam.

Again he rushed in, his arms working like twin piston rods. This time
Ned did not avoid the other’s rush. There was a rapid exchange of
blows, and then suddenly--so suddenly that nobody saw just how it had
happened, Sam Hinkley’s head was jerked back.

Whack! Ned had taken advantage of a fraction of a second when the other
was off his guard and landed a stinging blow full on Sam’s pug nose.
With a roar of anger Sam rushed in to retaliate. This time Ned was not
quite quick enough. He stepped sideways to avoid the other’s onrush,
but his foot slipped, and before he could recover his balance a heavy
blow from Sam’s ponderous fist sent him spinning across the porch.

Sam’s adherents in the crowd watching the two lads set up a shout of
delight. A broad grin overspread Sam’s face.

“Guess that finishes the lesson,” he jeered.

“On the contrary it’s only just begun,” retaliated Ned, and before Sam
knew just what had happened, two smart blows had rattled against his
ribs, the force of them making his teeth chatter as if with the cold.

But Sam speedily recovered himself, and for the next few minutes it
was give and take, with the odds rather against Ned, who was lighter
of build than the bully, and who was constantly forced back by the
latter’s rushes. Sam began to think it was all over.

“Well, Mr. Manners’ Teacher, how about you now?” he sneered tauntingly.

Ned did not reply, but he watched Sam like a cat. He saw that the bully
was beginning to wear out under the fast work of the last few minutes.
His chest was heaving and his breath came pantingly. He guessed that
Sam would have been glad to have called “quits” then and there.

But while Ned might have been willing enough not to fight at the
beginning of the battle, his blood was up now, and he was determined
to see the thing through. He despised fighting as being ruffianly
and unnecessary, but, in a case like the present, he felt that if he
allowed Sam Hinkley to walk over him, the latter would make it next to
impossible for him to remain in Nestorville.

He avoided another of Sam’s bull-like rushes with an agile step
backward. As Sam’s blow missed, Ned could hear him give a loud grunt,
a sound that told he was tiring.

“I’m wearing him down,” thought Ned, and watched carefully for an
opening that might afford him a chance of terminating the battle.

Sam “rushed” Ned again. This time he, too, appeared to be desirous of
ending the fight by a blow that would take all the fight out of his
lightly built opponent. But his blow landed on thin air.

Ned’s opportunity had come. His fist shot out like a streak of
lightning. It struck Sam under the chin, lifting him off his feet. He
toppled and fell backward, landing among the chairs with a crash that
sounded like a cook-stove falling downstairs.

“That settles him!” cried some of the crowd of boys that had gathered,
and “settle” Sam it did, in more senses than one, for, aroused by the
crash of his fall, the bully’s father issued from the hotel and
seizing his offspring by the scruff of the neck, angrily bade him get
inside.

[Illustration: “It wasn’t altogether his fault”, explained Ned.--_Page_
69]

“It wasn’t altogether his fault,” explained Ned. “I had his chair, you
see, and--”

“That’ll do, young feller,” said the elder Hinkley brusquely, “that’s
not the first time it’s happened. Sam had a licking coming to him and
he got it. I ain’t got nothing to say, ’cepting that supper’s ready
when you are.”

And in this eventful manner ended Ned’s first day in Nestorville. It
had surely been an eventful one, thought the boy, as he reviewed the
various experiences of the last twelve hours before turning into bed.

He was just about to turn out the light when his attention was
attracted to the door-sill. Something white was being shoved under the
door into the room. It was a folded bit of paper.

Ned sprang forward and picked it up. It was, as he had guessed, a note.
He opened it, and as he perused its contents, a smile of good-natured
contempt came over his face. This is what he read:

“You think you are smart, but you ain’t through with me yet. I’ll fix
you and when I do I’ll fix you good. S. Hinkley.”

“Too bad,” said Ned to himself, as he finished reading. “I’ve not
so many friends that I want to make any enemies. But after all, the
quarrel was not of my making and I don’t intend to allow Sam Hinkley’s
threats to worry me.”




CHAPTER VIII.

THE PLANS ACCEPTED.


Ned presented himself at High Towers betimes the next morning. He
found Jack Chadwick and Tom Jesson awaiting him at the workshop. Mr.
Chadwick was in New York attending to some business connected with his
interests. Mr. Jesson was in Boston delivering a series of biological
lectures, so that the boys had the place to themselves.

The eagerness of Ned to know the verdict of the two Boy Inventors must
have shown itself very plainly on his face, for almost as soon as he
had been introduced to Tom Jesson, Jack hastened to relieve the lad’s
anxiety.

“I suppose you want to know if it’s good news or bad?” asked Jack.

“I’ve hardly slept all night thinking of it.”

“Then I have something to tell you that you will be glad to hear. We
will help you manufacture the craft your uncle designed and----”

Ned’s glad outburst of thanks checked him for a moment, but Jack went
on to explain that he and his cousin would take only one-quarter
interest in the craft, leaving the remainder free and clear to Ned.
The cost of manufacturing would be borne by the Boy Inventors and the
patents, when the machine was completed, would rest in Ned’s name.

“Is that satisfactory?” asked Jack when he had finished.

“Satisfactory!” burst out Ned. “It’s generous--too generous!”

“Not at all. So far as money is concerned, when you know more about us,
you will know that Tom and I have plenty, most of it realized from our
inventions.”

“I know but----”

“Hold on a minute. Here we are, just dying for a chance to get to work
on something really new and neither of us with brains enough to think
up anything. You come along with just what we are looking for and we
feel more like thanking you than considering we are doing anything
wonderful.”

“Besides,” added Tom, “even one-quarter interest in the electric
hydroaeroplane ought to yield a handsome profit.”

“If, and it’s a big ‘If,’” said Ned with a laugh, “we can get it to
work. If not----”

“We wouldn’t tackle it if we didn’t think it was practicable,” said
Jack decisively. “So that ends that. Now come along, Ned, and be
initiated into the mysteries of the firm, for you know, you are now a
working partner.”

“Say, fellows!” burst out Ned enthusiastically. “I don’t know how to
thank you----”

“That’s all right. You help us out on building the machine and that
will be thanks enough. When we’ve got it working, we’ll shine in your
reflected glory and that will be satisfaction enough for us.”

The next hour was one of unmixed delight for Ned, interested, nay
wrapped up in mechanics as he was. He had never seen a workshop fitted
up on such a scale as that of Jack Chadwick and Tom Jesson,--a private
workshop, that is. Lathes and all sorts of machinery of the latest
pattern were driven by a powerful gasolene engine. Facilities were at
hand for making the parts of many of the boys’ devices. Three skilled
machinists were also employed, and summoning them about him, Jack
Chadwick briefly outlined to the interested men the big task they were
about to undertake.

He was in the midst of his explanations, when Sam Hinkley strolled in.
Jack looked at him sharply. One of his eyes was swollen and slightly
discolored. He glared at Ned savagely and the look was not lost on Jack
Chadwick.

As soon as he had an opportunity, Sam drew Jack aside and demanded, in
an indignant and aggrieved voice, to know if Ned Nevins was to work in
the shop.

“Yes, and on a partnership basis, too,” said Jack enthusiastically. “He
has been the means of introducing us to a wonderful invention. We are
going to start in on the work of its construction right away.”

Sam did not appear interested in this information except that a jealous
look crept into his eyes.

“I think you ought to know that he’s nothing but a rowdy,” he said.
“I’ll bet any invention he’s been telling you about is a fake.”

“The plans look good to us,” responded Jack, “and we are going to risk
it. What have you got against the boy, anyhow?”

“He’s a rowdy,” repeated Sam. “He blacked my eye last night.”

Jack, who had a pretty good insight into Sam’s character, could not
repress a smile.

“I thought you were invincible, Sam.”

“He didn’t fight fair. He forced me into a row,” grumbled Sam. “I
could have licked him all right if----”

“What had you been doing, Sam?”

“Nothing. He took my chair away and when I wanted it back he said I’d
have to fight for it and----”

“And you did,” commented Jack with a dry smile. “Well, Sam, my advice
is to forget it. If you think you’ve been injured I’m sorry, but Ned
Nevins appears to me to be an inoffensive sort of a lad, quiet and
unassuming.”

“Oh, he just puts on that to fool you,” muttered Sam.

At this juncture, Jack was called away by one of the machinists and
Sam, with a very bad grace, turned to some unfinished work at his
lathe. He was still engaged at this when Ned happened to pass by.

“I got your note last night, Hinkley,” he said. “Why didn’t you give
it to me in person instead of slipping it under the door?”

Sam made a sound resembling “G-r-r-r-r-r” and went on with what he was
doing.

“As I suppose you know,” resumed Ned, “we shall see a good deal of each
other in the future. Why can’t we be friends?”

Sam’s face contorted with rage as he dropped the tool he had been using
and faced round on Ned.

“Because I hate you, that’s why. You’re nothing but an interloper and a
faker and Jack Chadwick will find it out before very long.”

“I’m sorry you think that, Sam.”

“Why?” asked Sam, surprised at the other’s calm, even tone. His
outburst appeared to have no effect whatever upon the lad he had
desired to impress with his enmity.

“Because I am afraid you are going to be disappointed,” and with these
words Ned passed on.

The next few weeks were busy ones about the workshop of the Boy
Inventors, but gradually, almost imperceptibly, the electric
hydroaeroplane began to take shape. The enthusiasm of the boys
infected the workmen and even Sam Hinkley appeared to work with more
than usual fervor.

Briefly described, the hydroaeroplane portion of the craft consisted of
two twin boats, each about forty feet in length and constructed of a
special aluminum alloy jointed together by strong vanadium connections.
Between the pair of boats, which will be more fully described later,
the storage tanks, which were the novel feature of the Jeptha Nevins
craft, were placed.

In the center of each of the boats was a small raised cabin, the cabins
being connected by a hollow passageway. At either end of the craft
the wings, of biplane pattern, were attached. The wing spread was
ninety-five feet which, with the craft’s electric engines of enormous
power, gave the giant air-craft a lifting capacity of two thousand
pounds.

Above the storage batteries, and between the twin “boats,” were the
motors, each coupled to two sets of propellers placed fore and aft on
either end of the craft and outside of the wings. A light, but strong,
framework supported the outer bearings of the propellers and served
to give them sufficient projection to insure balance. The forward set
of propellers were so “pitched” as to pull the craft through the air,
while the after ones furnished a driving impulse.

One of the most important features of the invention was the device
by which electricity was made while she was in flight or skimming
over the water. This was a generator of considerable power geared to
the shafts of the propellers. As the craft drove along, the storage
batteries were constantly recharged by this device. For the initial,
or starting “charge” the batteries were furnished with “juice” by a
small compressed air-driven generator which could also be used in case
of accident to the automatically driven device. Thus the necessity of
gasolene was done away with and the Nevins craft was equipped, so far
as power was concerned, to cross the Atlantic Ocean. But, of course, no
such project entered into the minds of her young constructors.

The planes themselves were covered with sheets of aluminum attached to
frames of radiolite, a metal as light as aluminum and of great tensile
strength. Landing wheels, supported by powerful shock absorbers,
provided for alighting, and special balancing devices, attached to the
bow and to the stern of the novel craft, minimized the danger of coming
to earth with too great a shock to the weighty fabric.

On the top of each cabin was a powerful search-light, and each was
fitted out with two bunks and other conveniences as in the stateroom of
an ocean liner. The pilot house was mounted above the covered passage,
or tube, already referred to, which connected the two parts of the
craft. It contained a wheel not unlike that of an ocean liner and
levers to control the balancing wings and the pitch of the planes.

As for the engine-controls, the motor being electrically driven, the
machinery to control it was wonderfully simple. An apparatus not unlike
a switchboard, as may be seen in any powerhouse, was mounted within
convenient reach of the helmsman. The light controls also were affixed
to this board. Mastery of the huge craft was within instant power of
the driver. A signaling system to each cabin, in case of emergency, was
another feature added to the general completeness of the equipment.

Such is a brief description of the Nevins electric hydroaeroplane,
a craft in which the Boy Inventors were destined to meet as strange
adventures as had ever fallen to their lot.




CHAPTER IX.

THE ARRIVAL OF TROUBLE.


It would be tedious to dwell upon the details of the construction of
the craft which the boys, by unanimous vote, had decided to call the
Electric Monarch. The work went steadily on and Prof. Chadwick, who
had returned soon after the boys started work, rendered them valuable
assistance. The previous experience with aerial craft, which the Boy
Inventors had had, made the work progress far more rapidly than would
otherwise have been the case, although the plans and drawings left by
Jeptha Nevins were so detailed and exact that they encountered but few
very knotty problems.

One day, not very long before the Electric Monarch, which had been
finished in scarlet and silver, was ready for her trial trip, two
strangers appeared at the Hinkley House. One was a broad-shouldered,
clumsy-looking young man with a shock of black hair and carelessly
brushed clothes, the other a tall, cadaverous-looking person of about
the same age with shifty, rat-like eyes and a general air of furtive
watchfulness.

Some time before this event, Ned, as an active partner in the firm of
the Boy Inventors, had taken up his residence at High Towers. There
were two reasons for this. One was that it was far more convenient to
the work which was being rushed to completion, the other that as the
Electric Monarch neared the day for her trial trip, Ned grew more and
more nervous about leaving the craft unwatched.

Accordingly, he had a small cot fixed up in the corner of the workshop
where he slept at night. Ned himself would have been at a loss to
account for this nervousness; nevertheless he felt a vague mistrust.
It was not that he feared any harm Sam Hinkley might do to the craft,
for although there was no love lost toward Ned on Sam’s part, Ned was
pretty sure that the Hinkley boy would not dare take active reprisals.
But yet he felt that it was well to observe caution.

Sam came and went to his work as usual, and as he, as well as the other
workmen, had given their words not to let anything leak out about the
Electric Monarch till she was ready for a flight, no uneasiness was
felt about this circumstance.

As a matter of fact, even if it had been known that a big air craft
was being constructed at High Towers, it would not have excited much
comment in the village. The inhabitants of Nestorville had grown too
used to hearing about strange inventions being built at the big house
on the hill to feel any undue curiosity about them. And yet, Ned
vaguely felt that danger threatened.

The two strangers gave out at the Hinkley House that they were
traveling for a drug firm. They made themselves friendly with the
proprietor who, after being presented with cigars, voted them two
“good fellows.” Perhaps he might have thought them “inquisitive
fellows,” too, if soon after his new guests’ arrival, when he had been
summoned to answer a long-distance telephone, he had noticed one of
them slip up to the register, open it and search hurriedly for a name.

“It’s there all right,” whispered the one who had examined the book
as he slipped out from behind the desk again. “‘Ned Nevins--Boston.’
I suppose he registered from there because he didn’t want to run any
chances of being asked questions about Millville.”

“Shouldn’t wonder, Miles,” was the rejoinder of Hank Nevins, “but he
didn’t reckon that we was just as slick as he is.”

The two “drug drummers” were Hank and his unsavory lawyer friend, Miles
Sharkey. The two had been delayed in their pursuit of Ned by a very
important handicap, namely, lack of funds. But on Hank having written
to Mr. Mellville that they were on the track of the plans and had a
good chance of securing them, the money for their expenses, (much to
the surprise of both of them,) had been forwarded. They then lost no
time in heading for Nestorville and laying plans for the recovery of
the papers of the dead Jeptha Nevins.

When Landlord Hinkley came out of the telephone-booth, one of his new
guests stepped up to him.

“Recollect a young chap named Nevins?” he asked. It may be said here
that Hank and Miles had registered under assumed names.

“Nevins?” repeated the landlord. “Nevins? Well, I should just say I
did.”

“Stop here long?” asked Miles insinuatingly.

“Quite a few days till he went to live with them Chadwick boys up on
the hill yonder.”

Hank and Miles exchanged significant glances. They were on the trail
indeed now.

“Um-er, the Chadwick boys,” began Miles at a venture. “Chums of his,
eh?”

“Yes, I guess so, in a manner of speaking. My son Sam works for ’em,
too. He’s a bright lad, is Sam. Why, sir, I tell you around a bit of
machinery that boy’s a marvel. Only last week my wife’s sewing machine
went out of whack and gosh ter mighty ef that boy Sam didn’t have it
all fixed up hunky dory in two shakes of a duck’s tail. Nuther time----”

There is no knowing how long Mr. Hinkley might have gone on extolling
his son’s virtues had it not been for the fact that Miles and Hank were
far too impatient to listen to a lengthy catalogue of Sam’s bright
doings.

“Yes, yes,” rejoined Miles. “I’ve no doubt your son is a mighty bright
boy, Mr. Hinkley.”

“Gets it from his father,” put in Hank with a clumsy attempt at a
compliment.

Crude as the attempt at flattery was, Landlord Hinkley swallowed it
whole. He smirked his acknowledgments.

“Thank you, Mr. Avery,” this was the name Hank had registered under.
“Very handsome of you, I’m sure. Won’t you gentlemen hev a cigar?”

Both the gentlemen accepted with thanks, and while they puffed at
Landlord Hinkley’s aromatic weeds, they pursued further the subject
that was closest to their hearts.

“Fine cigars, these, Mr. Hinkley,” commented Miles, with a wink at Hank
to show that the remark was ironical.

“Oh, yes indeed,” responded the landlord, “Flor de Telphono, we call
’em. Telephone cigars, you know.”

“Telephone cigars, that’s an odd name,” said Hank, with a wry face
over his weed. Hank was one of those hollow-chested, pale-faced youths
who think it smart to smoke but do so only with a great effort of will
power.

“Yep, they calls ’em that, the boys says, because you can smoke ’em
here and smell ’em in Boston.”

This choice witticism having being properly laughed at, Miles and Hank
went further on their “fishing expedition.”

“These Chadwick boys now,” pursued Hank, “friends of young Nevins
likely?”

“Wa’al, I dunno. I reckon he’s working for ’em on some sort of
contraption. You know these Chadwick boys is right smart lads on such
doodads. The Boy Inventors, they call ’em. Reckon maybe you’ve heard on
’em.”

“No, I don’t know that I have,” rejoined Miles. “So young Nevins is
working for them, eh?”

“Er-huh. Has bin fer quite a spell.”

“Sort of mechanic, I suppose?”

“Wa’al, thar’ you got me,” admitted Mr. Hinkley. “I hearn’,” he went
on, sinking his voice and growing confidential, “that them boys is
working on some sort of er flyin’ machine er some sech foolishness.”

Miles and Hank flashed a glance of comprehension between them. They had
reached their goal, then.




CHAPTER X.

HEINY PUMPERNICK DILL.


“Hey, you black feller, dis be der place py vere der Poy Inventors
vork, I don’t dink?”

Old Jupe, the Chadwicks’  factotum, paused on his way from the
village with a big basket and looked his questioner over from head to
foot. It was an odd figure that he inspected. He found himself facing a
blond-haired youth of about eighteen with apple-red cheeks and bright,
twinkling blue eyes.

Perched on the top of the youth’s tow-<DW52> head was a small derby
rakishly tilted to one side. A green bob-tailed coat--it had probably
once been black--was carefully buttoned over a striped blue and white
vest. The turned up ends of his baggy trousers were so far from the
tops of his low, yellow shoes that they showed about two inches of
startling red socks.

“Who you done calling black feller?” demanded Jupe, with justifiable
indignation. “Ah’m a genelman ob color ah am, and I wants that
mistinctly undercunstumbled.”

“Vell, dond go py geddin’ a mads, Mister Gentelemans vot vos ,”
said the tow-headed youth in a conciliatory tone. “My name vos Heiny
Bumpernick Dill.”

For answer Jupe threw back his woolly head and burst into a roar of
laughter that showed two rows of white, gleaming teeth between his
thick red lips.

“Ho! Ho! Ho!--Ha! Ha! Ha!” he exploded. “Oh! gollyupmtions! ef dat
ain’t mostest funniest ting I eber heard.”

The tow-headed youth gazed at the <DW64>’s mirth with an expression that
was at first amazed and then grew rapidly indignant.

“Vos ist los midt you?” he demanded wrathfully.

“Loose? Der ain’t nutting loose wid me, am dere?” demanded Jupe,
fingering his waist band and in turn looking surprised.

“I saidt idt ‘Vos ist los!’” yelled the German boy. “Vot is idt der
madder midt you anyvay?”

“Oh, dat name! Golly to goodness, chile! Dat name suttinly got on mah
risibles. Heiny Pump it quick--oh! ha! ha! ha!” and throwing back his
head, old Jupe went off into another spasm of mirth.

“I saidt idt Bumpernick----”

“Was dat you say. Bumper----”

“Nodt. Bumper-Bumper. P-U-M-P-ER--Bumper!”

Jupe scratched his woolly thatch. This was getting too much for him.

“P-U-M-P-E-R spells Pumper, chile,” he said.

“Dots vot I saidt idt, aind’t it? Bumper--Bumbernick. Dot’s my name,
aind’t idt?”

“Say, lookah hyah, Massa Bumper, is you all crazy or am I?” demanded
Jupe.

“Vos dot you say? I am grazy?” bellowed Heiny Pumpernick. He dropped a
little wickerwork satchel he carried and doubled up his fists.

“I been adtletic feller alretty yet,” he shouted. “You bed my life you
no comes making der funs by me, py chiminy, black feller!”

“Was dat? Who yo’ all calls black fellers--you--you--yaller-headed
Dutchman,” ejaculated Jupe, thoroughly angry in his turn.

Now there is nothing on earth better calculated to arouse a German’s
ire than to call him a Dutchman, and the same is the case when a <DW64>
is addressed as a “black fellow” or a “<DW65>.” Both the German youth
and old Jupe were now fighting mad.

“I calls idt to you, black fellers,” sputtered out young Dill, doubling
up his plump fists. “I’m an adtletic feller, I pet you mein lifes. You
calls me Mister Dill oder I pust you vun py der nose.”

“Ho! ho! ef you all do dat you be a dill in er pickle, ho! ho!”

“Who is dot vot you calls a bickle? By chiminy, <DW65>, look idt out
midt yourself!”

Without more words the redoubtable Heiny Pumpernick Dill let fly
with his fists at Jupe who, for his part, was ready enough to begin
hostilities. Now it so happened that this Homeric battle took place on
the banks of the large lake mentioned in other volumes of this series.
It was a body of water used for experimenting with models of craft of
various kinds and had been the scene of the testing out of the diving
torpedo boat, as readers of the volume dealing with that invention will
recollect.

The fist of the exasperated German youth, as it leaped out, landed on
a spot on Jupe’s anatomy which, while it was not calculated to do him
much injury, still gave him plenty to think about.

“Woof! Wha’ fo’ yo’ alls hit me in der stomick?” indignantly roared out
Jupe. Without more ado he dropped the basket he had been burdened with
and the lid burst open. Instantly the ground was covered with a score
of lively hard-shell crabs, but in the heat of their anger neither of
the combatants noticed this.

Jupe’s retaliation for the German youth’s blow was vigorous.

“Gollyumptions! Ah makes yo’ all call me a genelman ob color befo’ ah
kicks yo’n off’n these hayar groun’s,” he cried indignantly.

The next minute it was Mr. Dill’s turn to cry “Oof!”

But he quickly recovered and then, closing in, the two pugilistic
heroes engaged in a tussle which speedily brought them in a rolling,
kicking, struggling heap to the ground. Over and over they rolled on
the banks of the lake and their struggles speedily brought them among
some of the escaped crabs. These lost no time in dealing with the
combatants. One fastened itself into young Dill’s long yellow hair
while another seized Jupe by the back of the neck. Two piercing yells
went up simultaneously.

“Oh! Ouch! Help! De debbil am got hold ob me by de neck!” roared out
Jupe.

“Leggo mein hairs, py chiminy!” screeched the German boy. “Himmel!
Donner! Blitzen!”

Over and over they rolled, with the crabs holding fast with a tenacious
grip. Their struggles quickly brought them to the bank of the lake.
What with anger, and what with pain, they were past noticing anything
and just as Jack and Tom, who had been attracted by the uproar, came
running down the gravel walk to ascertain its cause, a loud splash and
a despairing yell announced the fact that the two doughty heroes had
plunged into an element calculated to cool their wrath.




CHAPTER XI.

THE CONVERTIBLE SAUSAGE MACHINE.


Jack and Tom arrived at the brink of the lake just as the two
combatants, sputtering and splashing like a pair of grampuses, arose to
the surface.

“It’s Jupe!” cried Jack, “but how in the name of time?”

“But who is the other fellow?” shouted Tom.

“Never mind that now. Jupe can’t swim and the water is deep there.
We’ve got to get him out.”

The boys speedily stripped off their coats and kicked off their shoes
preparatory to plunging to the rescue, but before they could do this,
young Dill, who was a good swimmer, had seized Jupe by the back of the
neck and dragged him, half drowned, to the shore. Jupe, dripping with
water and mud, clambered out little the worse, except in appearance,
for his adventure.

He was followed by young Dill, who was a sorry-looking object indeed.
The water had caused the gaudy dye of his vest to run in great streaks
down his light- pants. His hat, which had stuck to his head
throughout the struggle, was sending streams of green water down over
his rubicund face, while round his feet, as he emerged from the lake
and stood before the boys, was a crimson puddle. The dye on young
Dill’s socks was certainly not of the “fast” variety, except in color.

At the sight of the two extraordinary figures Jack and Tom could hardly
refrain from bursting into roars of laughter. But they retained their
gravity and looked sternly at Jupe.

“Perhaps you will explain what this means?” began Jack.

“Ah-ah-ah-ah,” sputtered Jupe, opening and shutting his mouth like a
fish newly removed from the water.

“Well, we are waiting,” said Jack, while Tom turned away, suddenly
overcome by a mysterious fit of coughing.

“Vait idt a minutes undt I vill explanation idt to you,” volunteered
young Dill. “Dis is der vay idt vosn’t. I vos comin’ py der house to
see der Poy Inventors undt I asked idt ob dis black----”

Jupe suddenly came to life. Shaking his woolly head like a poodle he
shouted out:

“Don’ you alls done go fer ter call me no black feller,” he shouted.

“You no call idt to me Dutchman, I no call idt to you black fellers,
aber no mans call me Dutchman.”

“Wait a minute! Wait a minute! What’s all this about?” demanded Jack.
“How are we to understand anything with all this jabber? You there,
Mister----”

“Dill is mein name, sir,” said the young German with a dignity which
assorted oddly with his weird appearance.

“Well, Mr. Dill, you appear to be in a pickle,” said Jack with a grin
he could not repress. “Will you explain to me what was the cause of all
this?”

“Ah-ah-ah,” began Jupe again, but Jack shook his head at him and the
voluble young Dill told the story of the causes leading to the combat.

“Well, you both appear to have been well punished,” said Jack when he
concluded, “and now perhaps you will tell me what you wanted to see us
about.”

“Vot I vanted to see you abodt ain’d it?” asked the German boy.

“Yes.”

“I vanted to see idt der Poy Inventors alretty.”

“Well, you see them.” Young Dill’s face showed his astonishment, but he
wisely repressed any comment. “What can we do for you?”

“You can do me for a fine inventions vot I haf,” responded the
German youth. “I used to vurk midt a delicatessens pefore I pecome
an inventors. I haf midt me in dis liddle satchel a motel of mein
inventions.”

“Well, what is it? What is the nature of it?” demanded Jack.

“Idt iss a new kindt of sissage machine,” explained the proud youth,
forgetting all about his recent immersion in the glow of the inventor’s
enthusiasm, “chust py touching a lefer idt vill make bolognas,
frankfurters, liebervurst, or any oder kindt of sissage dot is alretty.
Vot you dink of him?”

“Huh!” grunted Jupe aside, “ah’s seed lots ob crazy inventors sense ah
wourk hyah, but dis am de fustest sausage machine inventor dot I ebber
clapped mah ole eyes on.” He stared at young Dill as if he had been a
natural curiosity of some sort.

Jack bit his lip hard to keep from laughing. As for Tom, he exploded
into a roar of laughter which he could not restrain. Young Dill looked
bewildered.

“I seel idt to you der Dill Convertible Sausage Machine for fif’
dousandt tollars!” he exclaimed with the air of a person making an
unheard-of offer.

“I am sorry, Mr. Dill,” said Jack, with exemplary gravity, “but we
couldn’t handle your invention if you made a much cheaper price on it.
However, you can no doubt dispose of it elsewhere.”

“Ugh! Yo’ alls better try er butcher shop, Dutchy,” muttered Jupe, “an’
ef dey don’ want it dere take it to a crazy house; maybe they kin use
it and yo’ alls, too.”

“Budt don’d you tink idt iss a goodt inventions?” persisted young Dill.

“Excellent! Fine!” declared Jack, with a side wink at Tom. “But we
couldn’t handle it at all. And now, Mr. Dill, we’ll have to say good
morning. We are very busy. I’m sorry for what happened, but really you
know you brought it partly on yourself.”

“Himmel! oder you hadt bought idt my convertible sissage machine I
vould nodt haf cared if I hadt been drowned all over,” declared young
Dill.

With a melancholy face he gathered up his little wicker satchel. The
boys were turning away when a sudden idea entered the young German’s
head. His face became irradiated with a ray of hope.

“I haf idt here a motel of der convertible sissage machine,” he said,
“aber you dakes me py der house I show you how to make bolognas,
frankfurters, lieber----”

“It wouldn’t be of the least use, Mr. Dill, you’d only be wasting your
time,” said Jack. “Excuse us now, please, we must hurry off.”

The young German was left standing alone on the gravel walk in the
midst of his rubicund puddle. He looked after the retreating figures
of the two boys and Jupe with a melancholy countenance. But he was
gratified none the less to observe that Jupe appeared to be getting
what is commonly known as a “calling down.”

“So dey don’d vant idt der convertible sissage machines,” he muttered.
“Vell dey don’d know dot dey let a fortune slip through dere fingers
der same as sissage slip through my machine, ain’d idt.”

His eyes fixed themselves on Jupe’s humbled figure.

“Chust der same,” he muttered in a low tone, “midt vun handt I can lick
you--<DW65>!”

Having done this justice to his outraged feelings, young Dill wrung the
water out of his coat-tails and set out on the road to Nestorville. He
thought that he had seen the last of High Towers. Had he but known it
he was destined to do the boys a singular service ere long, but as he
trudged along singing “Hi-lee! hi-lo!” to himself in a melancholy voice
he was totally unaware of this.




CHAPTER XII.

HANK AND MILES MEET THEIR MATCH.


“Mr. Avery” and “Mr. Reynolds,” the names by which Hank Nevins and
Miles Sharkey had chosen respectively to be known, were seated on
the porch of the Hinkley House taking their ease with their feet
elevated so as to afford a good view of the soles of their boots to any
passers-by, when young Dill came down the street.

Having recovered from his first disappointment, the young German, who
came of a persevering race, determined to remain in Nestorville for a
time at any rate and try to see the Boy Inventors again, regarding the
Convertible Sausage Machine, at a more auspicious time. He had a small
sum of money saved up, quite sufficient for his needs, and he resolved
to buy some new clothes at the first opportunity and then make a more
imposing descent upon High Towers.

As he rightly argued, his appearance that morning had not been
calculated to inspire confidence.

“Der great inventors, aber Eddy’s son, aber Macaroni, der inventor of
der hairless telegraph, nefer fall py a pond midt a <DW65>,” he mused.
“Maype dose poys dink I am a faker. Aber I don’d plame dem. I gedt idt
me a new oudfit of clothes undt den call aroundt again. ‘No trouble to
show goodts’ as de used to say idt ven I vos in pisiness.”

This train of thought brought him as far as the Hinkley House where our
Teutonic friend bethought him that after his strenuous exertions of the
morning some dinner would be the proper thing.

“Dis looks idt like a goodt quiedt hotel, aindt idt?” he said to
himself. “I makes idt a pest (guest) of meinself here, py chiminy.”

By some mischievous chance the odd figure of Mr. Dill, rendered doubly
striking since his immersion, caught the eye of Hank Nevins,--alias
Mr. Avery,--as he sat discussing, with his chum Miles, the best means
of carrying out their designs against Ned Nevins and his Electric
Monarch.

There was nothing that Hank liked better than to tease some one who
looked as if he might prove an unresisting victim, and here was one
ready to his hand, at least so he judged.

“Hello, Dutchy,” he remarked amiably, “been taking a bath with your
clothes on?”

Young Dill faced round on him and looked him over from top to toe.

“Aber I dink idt a bath do you no harm, mein freindt, aindt idt,” he
remarked blandly, “midt or midoudt clothes on.”

This was not exactly what Hank had expected, and a subdued chuckle from
some hangers on about the hotel porch did not increase his good humor.

“It’s a good thing we didn’t cross on the same boat,” observed Hank.
“If I’d seen you I’d never have landed.”

“So----” observed young Dill amiably, “veel dere vos no chance of your
seeing me alretty.”

Hank winked at the loungers in order to show them that he was now
prepared to have some fun with the queer-looking German youth.

“Is that so? How was that, Dutchy?” he asked with a grin.

“Pecos I come on a _passenger_ boat,” rejoined young Dill with all the
equanimity in the world.

A look of intense discomfiture spread over Hank’s face.

“The Dutchman’s too much for him,” he heard some one whisper. As might
be expected this remark did not tend to smooth over Hank’s feelings
toward the simple-looking young German. Instead he determined to launch
some shaft of wit at him that would squash him flatter than a pancake.
But so far all his attempts had proved boomerangs.

“I suppose you know all about sausages?” he asked.

Young Dill’s eyes glittered. Here was a subject in which he was deeply
interested.

“Oh ches!” he burst out eagerly, “sissages und----”

“Never mind that, Sauerkraut,” sneered Hank. “What kind of meat makes
the best bologna?”

Young Dill, who was smart enough in his way, saw that some joke was
going to be had at his expense if he did not look out. The loungers
leaned forward expectantly. Hank looked triumphant. At last he thought
he had the “Dutchman” up a tree.

“You vant to know vot kindt of meat makes idt pest bolognas?” he asked
innocently.

“That’s what I said, Dutch,” grinned Hank.

“You ought to know dot aber bedder dan me alretty,” said young Dill
gravely.

“Is that so, old Sauerkraut? How’s that?”

“Pecos der pest bologna is made midt calf’s headt, undt you vos veel
supplidt mid dot,” drawled out young Dill, and without waiting to hear
the roar of laughter that went up at Hank’s expense, he wandered into
the office and registered. His signature was a peculiar one. This is
how it read on the register:

“Herr Heiny Pumpernick Dill,--Inventor At Large (and Small)--N. Y.”

After ascertaining what time dinner would be ready, Herr Dill went to
his room and busied himself till the meal was served by tidying up as
well as he could, and removing the effects of his immersion. In this he
could not but admit that he was not very successful, and he resolved
immediately after dinner to saunter out and see what he could find in
the way of smart attire in the village.

“I vunder now if I couldt gedt idt some yellow gloves,” mused young
Dill to himself as he carefully unpacked the model of the sausage
machine and placed it on the floor.

“An inventor midt yellow gloves,--undt a redt necktie vould be some
class as an inventor. Aber he vould be as stylish as Macaroni oder
Eddy’s son.”

He fussed over his invention for a while to pass away the time till the
dinner bell rang out its summons. It was an odd-looking contrivance.
From a cylindrical steel box projected several hooked steel arms
manipulated with springs in a way which no one but the inventor could
by any possibility have mastered.

While young Dill was working on one of these arms, there came a sudden
sharp snap and he jerked his arm quickly out of the way and upwards.

“Himmel!” he exclaimed, “dot machine makes idt a preddy goodt trap
alretty. Dot lefer nearly caught it mein fingers. Maype if I can’t
sell idt as a sissage machine, I make idt a purglar trap oudt of idt
alretty--Hi-lee! dere goes der dinner bell! Dinner! I am coming on der
ger-jump!”




CHAPTER XIII.

READY FOR FLIGHT.


“Well, fellows, the Electric Monarch is ready for her trial trip at
last.”

Thus spoke Jack Chadwick the following day. The body of the great
land and water craft, looking like a butterfly with its wings off,
stood, resplendent in glittering paint and varnish, inside the big
construction shed.

All that remained to be done to fit her for the air was to equip the
framework with the wings which were made detachable. This had been a
necessary modification of Jeptha Nevins’ plans, as the shed in which
the craft had been constructed was not wide enough to permit the wings
being attached while the Electric Monarch was still under cover.

At first this had proved quite a problem, but with the aid of
Professor Chadwick who, as has been said, had taken an active part
in the work, the boys evolved a plan whereby the wings, (or planes,)
had been made detachable and could be bolted or unbolted at pleasure.
As the weight of each plane did not exceed fifty pounds, despite its
broad spread, the work of putting on or taking off the wings was a
comparatively easy one.

It was an interested group that stood in the shed and surveyed their
completed work. The Electric Monarch, they knew, was without question
the most unique craft of its kind that had ever been constructed.
Perfect in every detail as the great craft was, the boys felt a thrill
of pride run through them as they viewed their completed handiwork.
Professor Chadwick had spared no expense in aiding the boys at their
task and the result was as perfect a bit of mechanism as had ever been
assembled. Outside the shed the great wings were ranged on special
racks ready for attachment.

To fit the Electric Monarch for flight all that was required was the
charging of her powerful storage batteries. The craft would then be
ready for the crucial test which would prove whether she was to live
up to her name or be merely a mass of expensive junk fit only for the
scrap-pile.

It was small wonder then, that with the boys’ feeling of glad pride,
there was mingled no little anxiety. They stood on the threshold of
either a monumental triumph or an ignoble failure.

“Well, Ned,” said Jack, clapping their slender young assistant on the
shoulder, “there’s your Electric Monarch as fit for flight as she ever
will be.”

Ned Nevins turned his large eyes gratefully upon the boy he had learned
within the past weeks to love and respect.

“If she succeeds it will be owing to you, Jack, and you, Tom,” he said
happily; “as for Professor Chadwick, I owe him a debt of gratitude I
can never repay.”

“Nonsense, my lad,” spoke the Professor, with a kindly smile, “win or
lose, we have all learned much during the last few weeks. Ned, your
uncle, had he lived, would have been one of the world’s great inventive
geniuses.”

“I know it. I am sure of it,” said Ned gratefully. “My poor uncle! This
would have been a proud day for him if he had lived.”

He resolutely fought back his momentary feeling of sadness, and in
order to regain his composure helped Jack adjust a brace and tighten
one or two bolts.

“An’ you alls means ter tell me widout confabulation or fear ob
controversial flabbergumbugism dat dis yar monstrositfex am er gwine
ter fly er swim?” demanded Jupe, lapsing, as he always did under
excitement, into a perfect spasm of word coining.

“We hope so, Jupe,” rejoined Tom. “Why, are you aching for a ride?”

“Who, me?” and Jupe’s eyes grew wide. “No, sah! Ah’m nuthin’ but jes
er tumble-bug so far as de desirousness ob cirperambulatin’ de air am
consarned.”

“So you wouldn’t care to go up, Jupe?” inquired Ned, with a smile.

“No, sah! Wid emphaticness, ah says, N-O-No! Ef dat ting eber fall frum
de etarnal hebbins!--Laws-ee! What a confabulating smashup dere is
agwine ter be aroun’ hyar.”

“But we don’t figure that it will fall, Jupe. At any rate we are going
to fly out over the water and then the twin boats will keep us afloat
whatever happens.”

“Wa’al, sah, Massah Jack, be dat as it may, I’d rabber be on der groun’
lookin’ up dan in der sky lookin’ down,” declared the old <DW64> with
great positiveness.

“Let us make a final trip of inspection,” suggested the Professor.
The idea was hailed gladly. Led by Mr. Chadwick, the lads, laughing
and chatting gaily, went through the cabins and the strong structure
designed to support the Electric Monarch when in flight.

The staterooms were finished with glittering paint and everything
was spick and span as a new pin. Leaving the first cabin they passed
through the connecting tube into the other one. This having been
minutely examined, even down to the electric stove with which it was
provided, the professor led the way into what was, to the boys, the
most interesting part of the craft.

This was the pilot house. It has been already described, so we shall
not go into any details further than to say that every appliance was in
place, the wiring perfect, and all in readiness for the pilot to take
the wheel and guide the most wonderful craft of the age on her initial
flight.

Running fore-and-aft the entire length of the Electric Monarch, was a
narrow plank runway. This was so that any part of the craft might be
reached with ease when she was under way. The runway extended out to
the bearings of the propellers already mentioned, and it would be part
of the duty of whoever was entrusted with the oiling to venture out
occasionally within reach of the whirling blades and apply lubricants
to the bearings. On the water this would be a comparatively simple
matter. None of the boys was quite sure in his mind just how this duty
would appear when the craft was many hundreds of feet above the earth.

However, they were not worrying about such details as this just then.
There was but one thought uppermost in the minds of each of the eager
young constructors of the Electric Monarch.

Would she live up to expectations?

Possibly Ned, who was new to aerial work, was more nervous than his
companions over the thought of the trial trip. This was not surprising.
It requires courage of a rare sort to attempt for the first time to
climb the air in an absolutely untried craft. Yet this was the ordeal
they had to face. Moreover, there was a strong possibility that a
failure might result in death.

“Have you decided yet upon the course we will take on the trial trip?”
Jack inquired of his father as they finished their inspection, a tour,
by the way, on which Sam had not been invited, to his great chagrin.

“Yes; if all goes well we will fly straight for the ocean, provided
it is calm. That will give us a fine opportunity to test out the
hydroplane devices.”

“I feel sure enough of success to plan a voyage across the Atlantic,”
declared Tom confidently.

“That would be a little bit premature, my boy,” said the Professor,
with a smile.

“But provided the Electric Monarch is all we expect, wouldn’t it be
feasible?”

“I see no reason why not,” responded Mr. Chadwick. “At any rate in the
present state of aeronautics, if the dream of a flight across the ocean
is to come true, it seems to me that the Electric Monarch will be the
first to make the adventurous voyage.”

“Ned, you will be famous yet,” declared Jack. “I can see the name of
Ned Nevins in the Hall of Fame.”

“Huh! Maybe you see it in de bottom ob de deep blue sea,” sniffed
Jupe sceptically. The old <DW64> had no love for air craft since his
experiences in the electric storm in Yucatan.

While the foregoing scene had been transpiring at High Towers, a far
different one had been taking place at the Hinkley House. Having
finished his dinner, a meal at which he caused much merriment by his
odd antics and remarks, young Dill had sauntered out in search of new
apparel. He had succeeded beyond his wildest hopes in finding some
striking attire. From the stock of the village tailor he had selected
a suit of green, red and black check, originally made for some amateur
theatricals, a red waistcoat and a funny little blue hat with what he
called a “rudder” stuck on behind.

From the tailor shop, where he insisted on having his packages wrapped
up, young Dill passed to the haberdashery where he invested in a
startling necktie and some radiant socks. Then, with triumph in his
eye, and with his purchases under his arm, he retraced his way to the
hotel.

“By chiminy,” he said to himself, as he hurried along quite unconscious
of the wondering glances cast his way. “Py chiminy grickets, I show dem
vot style is, I bet you my life!”

The German youth went straight to his room to change into his gorgeous
raiment. He was still in the midst of this task, every now and then
stealing a look at himself in the mirror, when his attention was
arrested by the sound of voices in the next room.

The partitions in the Hinkley House were not particularly thick, this
being caused by the fact that landlord Hinkley, being of an economical
turn of mind, had partitioned off all his large rooms into two
apartments when he became the proprietor of the hostelry.

As a consequence, conversations carried on in even ordinary tones were
plainly audible in the adjoining rooms.

“Py chiminy, I hope dose fellers in der next room don’d talk it py dere
schleep,” mused young Dill as he tied his rainbow cravat, “or I get no
schlumbers, ain’d idt?”

The next instant his attention; was attracted to the speakers in the
adjoining room by a singular circumstance. It appeared that he himself
was the topic of their conversation.

“That pig-headed Dutchman with the comedy clothes,” was what he heard.

“Py chiminy, dot means me!” exclaimed young Dill, “der vind vos in
somedings. Dere vos a voodpile in der <DW65> in dot next room. I dink I
listen me a leedle closer, ain’d idt?”




CHAPTER XIV.

HEINY OVERHEARS THE PLOT.


Now, as my readers have no doubt seen by this time, Heiny Pumpernick
Dill was no fool. In fact, despite his eccentric outside, the German
youth possessed a keen, smart mind, which acted well in almost any
emergency.

Giving a final flourish and grimace at himself in token of admiration
of his new necktie, young Dill crept silently across the room and laid
his ear against the partition. In this position he could hear every
word that was being said in the next room.

“So you know that the Dutchman was at High Towers this morning?” said
one of the voices, that of Miles Sharkey, although, of course, young
Dill could not recognize it.

But he recognized the voice that replied without hesitation:

“Yes, I made it my business to find out about the sauerkraut-eating
Heiny,” was the rejoinder.

“Ah-ha! Now comes it oudt!” exclaimed young Dill to himself. “Dot is
der feller vot dinks he get funny midt me and laughs midt der wrong
side of his face yet.”

“Is he a friend of that High Towers bunch?”

The voice that was unfamiliar to the German youth put the question.

“Aber am I ein friendt or not?” muttered young Dill. “I vould like to
know dot.”

“No, he’s no friend,” it was Hank speaking, “in fact, from what I hear,
he got into a row of some sort up there to-day.”

“Aber dot’s right, budt idt vos in der lake vot I gedt,” said young
Dill to himself.

“So he is not one of the crowd at all?”

“No. He’s just a butter-in of some sort. I hear they get a lot of
cranks up there.”

“Oh, ho! So I’m a ker-ank, am I?” muttered the German boy, shaking his
fist at the unconscious pair in the next room. “You vatch me! I bedt
you my life some day I ker-ank you der wrong vay, mein freindt.”

“Well, crank or no crank, he certainly put it over on you before dinner
to-day, Hank. I’d advise you to leave him alone in future.”

“So his name vos Hank,” murmured young Dill, as he listened. “All
righd, Hank, you gedt fixed by a ker-ank--by chiminy, dot’s boetry
de firstest vot I ever make!” exclaimed the lad, as he formed the
involuntary rhyme.

“Oh, I’ll fix him, never fear,” rejoined Hank. “The tallow-headed
buttinski! But first we’ve got other things to attend to. The Dutchman
can wait.”

“You chust bedt he can vait, Mister Hank,” muttered Heiny, on his side
of the partition, “vaiting is one of der best things he does, und ven
he gedts idt goodt undt retty den he yump--by chiminy!--he yump!”

“That’s right, we had better discuss what we mean to do. If they make
that trial trip to-morrow we shall have to act quickly,” said Miles in
reply to Hank’s last remark.

“What did you find out?” he added.

“Well, I spent quite a bit of time snooping around up there. I found a
fool of a <DW52> man who told me a lot.”

“Dot vos der plack feller, I bedt you my life,” chuckled the German
boy, with his ear to the partition. “Veil he _iss_ a chump und dot’s
der first true word der feller in der next room has spoken.”

“So the <DW52> man was easy, eh?”

“Easy? I should say. I told him I was from Edison’s place and was just
looking around. He didn’t loosen up much so I gave him a dollar and he
told me all he knew. He’s a bigger chump than that Dutch kid.”

“So-o-o-o!” fairly hissed Heiny, on his side of the wall, “veel,
Mister Schmardty, maype dot der Tutch poy is not so much of chump as
you dink.”

“Well, what did he tell you?” demanded Miles impatiently.

“About all I wanted to know. I posed as being interested in young
Nevins, but not wanting him to know that I was around till the success
or failure of the Electric Hydroaeroplane was assured.”

“Now comes it oudt,” muttered Heiny, pricking up his ears.

“Yes, and then--upon my word you are slow. Hank,” came Miles’s voice.

“Humph! that’s all the thanks I get after all the work I’ve done,” came
in an aggrieved voice from Hank.

“That’s all right, Hank. Of course I know you’ve done well. But get
down to cases.”

“Well, then,” continued Hank in a sulky tone, “I learned that the
Electric Monarch is completed. The trial trip will probably take place
to-morrow morning, or it may be delayed till night. If we mean to
strike, we must do so quickly.”

“Yes, if we can’t get hold of the plans we must do all we can to
<DW36> the ship, for if once it is a proved success, our game is up.”

“That’s right. Confound that young cousin of mine. He’s checkmated me.”

“Not quite yet, Hank,” was the confident reply. “Even if we don’t get a
chance to injure the ship or steal the plans, I’ve yet another scheme
up my sleeve--a legal one.”

“A legal one?”

“Yes, I’m smart enough for that. But we won’t work it till the time
comes. In the meanwhile we must do what we can to stop this trial trip
from coming off.”

“Have you any plans in that respect?”

“No, I confess I hadn’t till you told me about that Dutch boy. Why
can’t we use him?”

“What, that dunderhead!”

“Ah-ha! So-o-o-o I am a dunderhead, too, iss idt?” growled Heiny
from his side of the partition. “I’m dunderheadt midt ears on my
dunderheadt, though, py chiminys!”

He started counting on his pudgy fingers.

“Chump! Dutchman! Dunderheadt! Dot makes three! Very veel, Hank, I
makes it all ger-skvare midt you before I gedts drough, I bet me.”

“Of course he’s a bonehead,” came the other voice, which made poor
Heiny squirm.

“But that’s all the better for our purpose. If he had any sense he
might suspect something. As it is----”

“He don’d know somedings,” chuckled Heiny to himself.

“Hanged if I can see what you are driving at,” growled Hank. “I
wouldn’t employ that Dutchman to mop off a floor.”

“Of you did I mop idt midt you,” muttered the young German indignantly.

“Now, listen, Hank,” said Miles, “the German got into trouble up there
to-day, you say? Very well, he’s naturally sore at the whole High
Towers crowd. All right. We go to him and offer him a chance to get
even. Nobody would suspect him of contemplating any harm to anything or
anybody; he hasn’t got sense enough.”

“Py golly, I premeditate harm to you all righdt, mister,” grunted young
Dill angrily.

“What do you mean to get him to do?” inquired Hank eagerly.

“We’ll discuss that later. The thing to do now is to get him on our
side.”

“I’ll attend to that,” said Hank, “leave it to me to fix that Dutchman
so that he’ll eat out of my hand.”

“Vell now dot is nice of you,” said young Dill to himself as the two
men in the next room vacated it, closing the door behind them.




CHAPTER XV.

THE BURGLAR TRAP.


The German lad finished his preparations for astonishing Nestorville
with elaborate care. Having adjusted his derby at what he considered a
fetching angle, he prepared to descend and to conquer.

“Maype so I cotch idt an heiress,” he said to himself, “undt den I
bodder no more midt der convertible sissage machine.”

Heiny was perfectly right when he concluded that he was about to
astonish Nestorville. The porch of the hotel was fairly well occupied
when he descended, and the street was also pretty well thronged. The
sight of the German youth in his tight-fitting check clothes, gaudy
socks, rainbow tie and yellow gloves created an amount of attention
which gratified Heiny to the full.

“For der first time dey see idt in dis penighted village vot clothes
vears a chentleman,” he said to himself.

His first jar came when a small boy stepped up to him.

“Say, mister?” said the urchin.

“Vel, vot idt iss, mein poy?” asked Heiny.

“Wot cher sellin’?”

“Sellin’? I do not comprehension you.”

“What you advertisin’ then. Squirts Savory Soap or Odles Orient Oats?”

“Mein leedle poy, I adtvertise idt nuddings.”

“Nor sell nothing?”

“Nein. I am a chentleman of leisure undt an inventor.”

“Oh, climb back in der cage,” advised the rude urchin, and amidst a
shout of laughter from his cronies he dashed off.

“Climb py der cage?” muttered young Dill, looking about. “I see no
cage, undt efen if I didt I vouldn’t climb in--no, sir, not vile I haf
nice room midt conversationings thrown in free of charge for nuddings.”

“On a trip?” asked a tall gangling village youth of the “half-baked”
age, approaching the German boy.

“No, I am oudt on der ocean sufferin’ seferely midt sea sickness,”
responded Heiny with withering scorn, and the village youth subsided.

“I vonder vot is der madder midt me?” thought young Dill to himself,
seeing that he was the observed of all observers in and about the
hotel. “Oh, vell! I subbose dot a vell-dressed man is not often seen
hereabouts.”

He sat down in a chair on the porch and before long a
cadaverous-looking individual, with lank, black hair and a solemn
countenance seated himself beside him.

“A stranger in our city, sir, I take it?” began the newcomer.

“Yes, dey all seem to dink I am stranger dan anydings dot dey see yet,”
rejoined Heiny good-naturedly.

“A natural ignorance, my dear sir. You, I take it, come from the
centers of cosmopolitanism?”

“Vell, I don’t know dot town. I come from New York,” was the German
youth’s reply.

“A noble city, sir.”

“Vell, I don’d know about dot. Dey vouldn’d buy mein convertible
sissage machine.”

“What, you are an inventor?”

“Ches, an inventor at large--(undt schmall)----” declared young Dill,
throwing out his chest proudly.

“You must make a great deal of money.”

“Oh, enough to lif py meinself--enough for dot! I don’d vant for
nuddings. Der best in clothes or foodt is none too goodt for me,” and
the German swelled with pride. He did not notice the glitter that had
come into the eyes of the cadaverous man at the mention of money. He
eyed young Dill cunningly and then asked:

“A guest of this hotel, sir?”

“Ches, I stop here. Idt iss nodt a badt blace but der pickles iss no
good,” said young Dill loftily, as if he had been used to hotels all
his life.

The cadaverous man leaned over toward the German youth confidentially.

“If you carry large sums with you I need not warn you of the danger of
thieves.”

“Oh, no, I am careful midt mein money,” young Dill assured his
new-found friend, “I alvays schleep midt idt in der toe of vun of mein
shoes,”

“Ah, indeed. May I ask why?”

“Vell, you see, ker-ooks dey look under der pillow undt in der clothing
but dey nefer dink of lookin’ py der toes of mein shoes. A goodt
scheme, ain’d idt?”

“Excellent. Good evening, my dear young man. I have much enjoyed our
conversation.”

And the cadaverous-looking man bowed himself out, looking back as he
went with a covert smile on his face.

“Thank you, my Teutonic friend,” he said to himself as he made his way
across the office. “I’m much obliged to you for confiding to ‘Deacon’
Terry the place where you hide your roll. To judge by your clothes it
must be a fat one. I think I’ll investigate your shoes to-night.”

So thinking, “Deacon” Terry, the notorious hotel thief, examined the
register, made sure of the location of “the inventor’s” room and then
politely requested that his baggage be transferred to a room on that
floor, as the room he had been assigned to did not please him. His
request was at once granted, for the “Deacon” possessed an impressive,
not to say ministerial manner, which gave not the least clue to his
real character.

Without appearing to feel the slightest concern in them, young Dill
watched, with intense interest, the movements of Hank Nevins and Miles
Sharkey, following the conclusion of the evening meal. Matters were
further complicated in the German youth’s mind by the fact that they
did not approach him, as he had expected, but instead, engaged the
landlord’s son in conversation.

By adroitly maneuvering, young Dill succeeded in getting into a
position where a pillar in the lobby hid him from view and afforded
a capital screen behind which to listen to the formation of the
plot which he was sure was going forward. He had learned earlier in
the day that Sam Hinkley worked at the High Towers workshop and was
considerably surprised when he saw the boy allow himself to be drawn
into talk with Hank and the man the German youth knew as “Der stranger.”

“I’ll bedt idt er pretzel dot der iss some more crooked pisiness
going forvarts,” he thought to himself as he watched Sam in deep
conversation with the pair he already knew plotted mischief to the
Electric Monarch. “Does two fellers iss so crooked dey could behind a
corkscrew hide. I vatch undt lisden. Maybe I find idt oudt some more.
If I do, I tell der poys by der Electric Monarch and den maybe dey give
me a chob.”

With this idea in mind, he worked his way to the position he adjudged
most favorable for his eavesdropping. Now young Dill was no friend to
sneaky ways, but in the present case he felt that the end justified
almost any means. He knew enough to realize that the Boy Inventors’
project was threatened by two men whom he instinctively felt were bad
characters, even if he had not overheard their talk of the afternoon.

He had not listened long when all his suspicions were confirmed. With
cunning skill Miles Sharkey was working on Sam Hinkley’s hatred of Ned
Nevins to enlist Sam in the plot against the Electric Monarch. But to
young Dill’s chagrin, he could not get close enough to hear all their
conversation without risking being discovered. He had, therefore, to
content himself with fragmentary bits. But such as these were, they
were quite sufficient to inform him that Sam Hinkley was ready to turn
traitor to his young employers.

“Then you’ll do it?” were the last words the German youth heard Miles
address to Sam Hinkley.

“You can depend on me to fix the young sneak,” he heard Sam answer.
“But when do I get my money?”

“When we get ours from the party I told you about. Is that
satisfactory?” asked Miles, who appeared to act as spokesman.

“That’s all right,” was Sam’s reply, as he strolled away, and the two
conspirators exchanged triumphant glances.

“Now dey come py me, I bedt you my life,” muttered the young German
to himself as he flopped into a chair and appeared engrossed in a
newspaper which happened, by good luck, to be lying there. Sure enough
it was not many minutes before he heard a honey voice addressing him.

It was Hank. He expressed great regret for the occurrences of the
morning.

“I don’t know what got into me,” he said, “anyhow I apologize very
sincerely.”

“Oh, dot’s all righdt,” said young Dill easily, “und at dot I don’d
dink dot you hadt very much on me.”

Hank agreed, and then after some more conversation he approached the
subject that young Dill knew he had been leading up to all the time.

“You know those Boy Inventors, as they call them, up at High Towers?”
he asked.

“Vell, I can’t say dot I know dem,” replied Heiny truthfully, “but I
like to get a chob by dem.”

“Oh, looking for a job, are you?”

“Ches, I needt some money preddy badtly und I don’d mindt telling you
dot I aindt particular how I get idt alretty.”

Hank fell into the trap readily. “This fellow’s easier than I thought,”
he chuckled to himself. He proceeded to “feel out” the German youth a
little more, and then made him a confidant in their plans, young Dill
appearing to fall in readily with all their schemes.

Briefly the plot was this. Young Dill was to present himself at High
Towers in the morning. Seemingly he was to be in quest of work. But
his real mission was to take advantage of any opportunity that might
present itself to disconnect one of the wires leading from the storage
batteries to the motor. Failing in this, he was to injure the Electric
Monarch in any way that he could, Hank having previously found out that
young Dill understood considerable about machinery.

To all this the young German appeared to agree. In fact he was even
enthusiastic.

“I guess I make more money on dis chob dan I vouldt oudt of mein
sissage machine,” he said.

“Money!” exclaimed Hank. “Why, if you can pull this thing off right
you’ll be able to buy a new suit every ten minutes.”

“Den I’m your man,” said young Dill.

Soon after this he went to bed. He would have liked to go to High
Towers that night but he knew that he was watched. Moreover, as there
was to be no attempt made to injure the machine till the next morning,
he would not have accomplished any useful purpose, except perhaps, to
scare the plotters away, which was the last thing he wished to do.

Before turning in, the German youth expended a few loving caresses on
the convertible sausage machine, and then, placing it on the floor, he
tumbled into bed and soon his snores proclaimed that at least one guest
of the Hinkley House was enjoying peaceful slumber.

It was after midnight that a door down the corridor from the German
youth’s room was cautiously opened and the cadaverous head and lank
black locks of “Deacon” Terry protruded themselves into the dimly
lighted passage. Apparently satisfied that every one was in bed, the
“Deacon” slipped out of his room and tip-toed down the passage to young
Dill’s door.

Bending, he listened at the key-hole. The nasal music which greeted his
ears caused a satisfied smile to creep over his features. He fumbled in
his pocket for a minute and then a jingling sound proclaimed that he
had found what he was in search of--a bunch of skeleton keys.

With a deftness born of long practice the “Deacon” inserted one of
the keys in the lock of young Dill’s door. There was the slightest
of clicks and then the Deacon cautiously pushed the portal open. An
instant’s pause, and then with the gliding motion of a snake, he
slipped through the door.

“Snap!”

A sound like the firing of a pistol was followed almost immediately by
a most appalling yell.

“Help! Ouch! Help!”

The next moment a figure came flying into the corridor. Attached to
it was what at first sight appeared to be a gigantic spider. Down the
corridor the figure fled, yelling at the top of his voice.

All through the hotel, doors could be heard opening and shouts and
cries rang through the entire structure from office to garret!

“It’s fire!”

“There’s murder!”

“Call the police!”

“Thieves!”

“Fire! Fire!”

Mingling with these and a dozen other frantic cries from alarmed guests
came the clanging of gongs as the night clerk, aroused from his doze in
the office, sprang to the emergency alarm and pulled it. This redoubled
the confusion.

In the midst of the pandemonium there came skyrocketing madly down
the stairs into the half-dressed crowd swarming in the lobby, an
extraordinary and alarming figure. It was that of a man clad only in
shirt and trousers upon whose face was stamped the wildest terror.
Frightened cries broke from his lips and the horrified onlookers
perceived that, attached to him, behind, was a gigantic spider, or such
at least the thing appeared.

With a last frantic cry the victim of the repulsive-looking creature
gave a bound and fell headlong on the floor of the crowded lobby. As he
did so there was a metallic clang, the “spider” was detached from his
waistband and the excited crowd saw that it was in reality a metallic
device of some sort.

It was just at this moment that the fire department and the police
department, the latter consisting of two men and a chief, with a
resplendent star of pie-plate proportions, burst into the thronged
lobby. The chief rushed up to the prostrate man and raised him to his
feet.

The instant his eyes encountered the other’s face, the village
functionary gave a cry of astonishment.

“It’s ‘Deacon’ Terry, the crook!” he exclaimed, with a firm grip on the
man. “There’s a description and a reward out for his capture.”

“What have you been up to now?” asked one of the policemen, but before
the discomfited thief could reply, a strange figure in red and white
striped pajamas shoved its way through the excited throng that jammed
the lobby.

“I can tell you dot. Dot feller dere vos try to make a robberies midt
mein room. Mein burglar trap--dot used to be a sissage machine--makes a
capture by him.”

“Who in thunder are you?” demanded the chief, regarding the
wild-looking German youth with amazement.

“I am Heiny Pumpernick Dill, inventor at large (undt schmall) of
der Convertible Sissage Machine. Dot iss, idt used to be a sissage
machine--now I make idt of him a burglar trap.”

“Say, is this fellow crazy or what?” exclaimed the chief, who had been
unable, not unnaturally, to make head or tail of this jargon.

“I think I can explain, chief,” said the night clerk, coming forward.
“It’s plain enough that this fellow,--the ‘Deacon’ as you call
him,--tried to get into Mr. Dill’s room. He succeeded, but instead of
robbing Dill he was seized by this what-you-may-call it.”

He indicated the sausage machine lying in a heap of spider-like limbs
and springs on the floor near-by.

“Dot is not a what-you-mighdt-call-idt----” began young Dill
indignantly, “idt is a sissage machine. I pudt him der door py ven I
go to mein schleep. I suppose dot dis feller got ger-grabbed by idt ven
he come to take all der money dot I told him early in der efenin’ I
hadt in mein shoes.”

It was some time before things quieted down and the notorious “Deacon”
was taken off to the village lock-up. Young Dill was the recipient of
many congratulations on the success of his “burglar-trap.” But somehow
they did not please him. As he returned to his interrupted slumbers he
muttered to himself:

“I am a preddy bum inventor alretty. I don’d know meinself vot I
invent. Here I go to vurk undt make idt a fine sissage machine undt now
I haf to turn idt into a burglar-trap--Himmel!”




CHAPTER XVI.

THE LOST LEVER.


Bright and early the next morning the young inventors, and the workmen
attached to their “plant,” wheeled out the framework of the Electric
Monarch and the business of attaching the wings was begun. It was
just half an hour from the time the work began to the moment when the
last bolt was in place, and like a huge red and silver butterfly the
wonderful craft stood poised ready for flight.

The boys had had but little sleep and their dreams had been of skimming
the air or gliding over the surface of the sea. Now, as they stood back
and gazed at their completed handiwork, they felt a proud thrill of
work well done. Come what might of the trial trip, they felt that they
had done their very best.

Only one thing marred their delight at the completion of their long
task. Professor Chadwick, who from time to time suffered from severe
headaches, would be unable to accompany them on the initial voyage.
Instead, one of the workmen, a man named Joyce, was selected to go
along.

When everything was in readiness for the start, Jack visited his
father’s study. He was in hopes that even at the eleventh hour the
Professor might feel well enough to accompany them. He well knew
what a disappointment it was to his father to have to remain behind.
But Professor Chadwick had been warned by his physician not to risk
excitement when suffering from one of his nervous headaches.

Jack found his father lying on a lounge in the library.

“No, Jack, my boy,” he said in answer to the boy’s anxious inquiries,
“I’m afraid the trial trip must be made without me. I am under doctor’s
orders and cannot disobey them.”

“I wish you could come, father,” replied the boy, “but if everything
goes off all right you will have many opportunities to ride in the
Electric Monarch. Now, since you can’t come, I am going to entrust to
your care the plans and blue prints of the craft.”

“Yes, they will be safer here.”

“I have just brought them from the workshop. See, here they are,” and
Jack produced a voluminous roll of papers. “We are responsible to Ned
Nevins for the safety of these and we must see that they are looked
after carefully.”

“Put them in the safe, my boy, and then give me the combination. If I
feel better later on I should like to look them over.”

Jack went to a large wall safe in one corner of the room, opened it and
placed the papers within. He then gave the combination to his father on
a slip of paper. When this had been done he felt easier in his mind.

“They are safe enough now,” he thought. He mixed his father a draught
of medicine and then, summoning a servant, he told her to be ready to
answer any call from the library, in which room Professor Chadwick
intended to spend the day.

When this had been done Jack felt that further delay would be useless.
Bidding his father good-bye, and promising to give him every detail of
the trip on his return, the boy hurried out to join his comrades.

It was a cloudless day. There was not a breath of wind to stir the
leaves. A better morning for the testing of the Electric Monarch could
not have been imagined.

“Well, Tom, we’re all ready, I guess.”

“As ready as we ever will be, Jack. The big moment is due. Everything
all right to your mind, Ned?”

“Down to the last nut on the last bolt,” replied young Nevins
positively.

“Then we had better climb on board and get ready for the start.”

Joyce, a stalwart, middle-aged mechanic, followed the boys on board the
Electric Monarch. They first visited the pilot house. It had already
been decided that Jack, on account of his previous experience with
aerial craft, was to have the wheel. He gave a last look over the
equipment. The next instant he uttered an exclamation of dismay.

“The landing lever is gone!” he exclaimed.

“What!” the cry came from all three of his companions simultaneously.

“It’s gone!” cried the boy. “Look here, it’s been unbolted from the
sector. Boys, the trial trip is off if we can’t find it.”

As it was the landing lever that controlled the descending impetus
of the craft, it can readily be seen that it would have been
foolhardy--suicidal, in fact--to have attempted to start without it.

“It was here the last thing last night,” cried Ned. “I know because I
looked the whole craft over before I turned in.”

“Just the same, it is gone,” declared Tom.

“Somebody has taken it,” struck in Joyce.

“Yes, somebody with a spite against us,” added Ned, and in his mind the
thought of Sam Hinkley flashed up.

“Has anybody seen Sam about this morning?” he asked.

No, nobody had. The boy had not put in his usual appearance, which
seemed odd, for recently he had appeared to take more interest than
usual in the Electric Monarch.

“You surely don’t suspect----” began Tom.

“I don’t know what to say,” interrupted Jack, “it looks odd, that’s
all.”

“But what object could he have had in taking it?” asked Tom.

“Better ask Ned that,” was the response. “He told Ned he’d get even
with him some time for giving him a lesson on the porch of the Hinkley
House.”

“Well, suspicions won’t find that lever,” said Ned. “Suppose we look
for it. Let’s start a hunt.”

“Not much use,” declared Joyce. “Whoever took that lever has hidden it
where we can’t find it.”

“I guess that’s so,” admitted Jack ruefully. “I don’t want to accuse
any one till we know, but it looks as if----”

A shout from beside the ship interrupted him. It was Jupe. He was
pointing down the hill.

“Gollyumption!” shouted the old <DW64>, who had been an interested
though inactive onlooker. “Hyar comes dat crazy Dutch kid!”

Sure enough, up the hill was coming, as fast as his pudgy legs would
carry him, the rotund form of the doughty inventor of the convertible
sausage machine.

“Bother him. We don’t want that pest around now. Hullo! what’s the
matter with him?”

For young Dill was waving his arms like a windmill. He dashed up,
puffing like a locomotive, the next minute. It was plain he was wildly
excited about something. But for some seconds he could only puff and
gesticulate while his eyes rolled as if he had eaten something that had
disagreed with him.

“What’s the trouble, are you sick?” asked Jack, looking down from the
pilot house.

“Aber-<DW30>--Poys! You haf missed idt somedings--<DW30>--from der--sheeps?”

“Sheeps?” exclaimed Tom, puzzled.

“He means ship,” exclaimed Jack. “Say, fellows, he knows something
about the missing lever. Is that it, Heiny?”

“Ches. Der liver of der sheep iss gone, ain’d idt?”

“It certainly has. Do you know anything about it?”

By this time Heiny had recovered his breath. In a torrent of speech
that nothing could stop he rattled off the story of the overheard
conversation, of Sam’s treachery and of the way in which he had
seemingly fallen in with the conspirators’ plans. Early that morning
he had got out of bed and tracked Sam Hinkley to High Towers. He had
watched while the treacherous youth had unscrewed the lever and then
had followed him through the fields to an abandoned well into which the
rascally boy had thrown it. During his narrative, Heiny gave a good
description of Hank Nevins and Miles Sharkey, from which Ned had no
difficulty in identifying the plotters. The manner in which they had
discovered his whereabouts, though, was, of course, a mystery to the
lad.

But there was no time to waste just then in discussing the best means
of ensuring the punishment of the conspirators. The main desire of all
the boys was to get back the lever and be off on the interrupted test.
Under young Dill’s guidance the old well was soon found. It was almost
filled up with rubbish and it was an easy matter to get the lever out.

“I don’t know how we can reward you for this service,” Jack said to
young Dill as they made their way back to the Electric Monarch.

“Dere is an easy vay to do dot,” said the young German, with the air of
one who already has his mind made up.

“Well, what is it?”

“Make me der mashed shot of der Elegdrig Monarch.”

“The what?” Jack regarded the lad with a puzzled look. Young Dill had
certainly done them a splendid service and Jack, as they all did,
wished to reward him for it in some substantial way.

“Der mashed shot--der goot luck--der----”

“Oh, the mascot!” cried Jack.

“Dot’s idt. I make idt a fine mashed shot. I am strong. I am villing. I
am an inventor, at large (undt schmall) und----”

“But just what are the duties of a mascot? If I make you one I’d
like to be sure you understand them,” said Jack with a wink at his
companions.

“Oh, dot vos easy. Der dooties of a mashed shot are to sit in a corner
undt keep making a noise like a rabbid’s foot oder a horse’s-boot.”

“Horseshoe, I guess you mean. However, you seem to have a pretty good
idea of the job and we can use you, anyhow, I guess.”

“Den I gedt der chob?”

“Yes, you are one of the crew of the Electric Monarch.”

“Hoch! Der Monarch!” shouted Heiny Dill, throwing his funny little
“rudder” hat high in the air, “ven do vee start?”

“Thanks to your clever detective work, right away.”




CHAPTER XVII.

OFF AT LAST!


The frame of the Electric Monarch thrilled to the first impulse of her
powerful motors. But that thrill was nothing to the sense of suppressed
excitement that ran through the boys’ veins as Jack, with throbbing
pulses, set the lever that sent the electric current into the driving
machinery.

Outwardly calm, every person on board stood at his station waiting
the word for the start. Tom Jesson was in the bow, Joyce, oil can in
hand, was at the stern. Ned Nevins, pale but keeping a firm grip on his
nerves, stood by the motors. His “big moment” had come at last. The
dream of Jeptha Nevins was to be put to the test.

Heiny Dill had had a special office created for him at the last moment.
He was, in addition to his self-conferred title of mascot, the “chief
cook and bottle washer”--in other words, the steward of the Electric
Monarch. He felt the responsibilities of his office to the full as he
stood with his rotund face stuck out of the port cabin window waiting
for the start. He already had the electric stove going and a big kettle
of boiling water on it. Just why, he could not have said, but he felt
that it was in line with his responsible position to be doing something.

“Hold tight, everybody. We’re going up!”

The shout from the pilot house was like a bugle call. Each boy
involuntarily straightened up at his post. The propellers beat the air
faster and faster. On the “bridge deck” the boys held tightly to their
caps. It was like being in a hurricane. The mighty power of the motors
made a roaring noise, like the voice of a cataract. The craft shook
from stem to stern like a live thing struggling against captivity.

Suddenly there came a jerk and a yell from Heiny as, amidst a crashing
of pots and pans, he was flung to the floor. On the “bridge deck” the
crew hung on tight. Their faces showed the tense strain as Jack applied
full power.

Off like an arrow from a bow shot the great craft across the smooth
<DW72> leading down to the lake. The speed was terrific. The craft
pitched and swayed so that it was only by holding on for dear life that
the boys could keep their feet.

“Ledt me oudt! Ledt me oudt!” shrieked Heiny, from amidst the wreckage
of his cooking utensils. “I don’d vant to be a mashed shot!”

“Gracious, if we don’t rise in a second we’ll be in the lake!” cried
Tom in dismay, but above the roaring of the motors and propellers no
one heard him. But the same thought was in the minds of all. Ned, white
as ashes, peered straight ahead as the massive craft dashed down the
hill. Were all their hopes doomed to disaster, after all?

In the pilot house Jack saw the impending disaster. He threw his
entire weight against the lever that set the wings at a rising
inclination. The device was new and stiff. His most strenuous exertions
failed to move it.

He heard a voice at his shoulder. It was Ned Nevins. He had guessed
that something was the matter and had clawed his way into the pilot
house down the pitching, swaying bridge.

“The rising lever! Quick!” he cried.

“I can’t move it. It’s stuck!” shouted back Jack.

Ned braced his foot against the sector and both boys threw the last
ounce of their strength into making the refractory bit of machinery
move. It did, with a suddenness that threw them both to the floor of
the pilot house.

But the next instant they gave a glad shout of delight which echoed
from one end of the craft to the other.

The Electric Monarch was rising, shooting straight upward toward the
blue heavens at tremendous speed!

Jack scrambled to his feet like a shot. For one instant the Electric
Monarch was shooting skyward without a guiding hand at the wheel. The
next moment her young skipper, with a firm grasp of the spokes, was
directing her course due eastward toward the ocean.

While he did this, Ned set to work with oil can and file on the lever
which had so nearly caused disaster. He soon had it fixed and had taken
to heart a lesson which had for its text, “It’s the little things that
count.”

“Gracious,” he said to Jack, as they shot straight onward at a height
the barograph showed to be 2,500 feet, “that lever came near wrecking
us.”

“Never mind that now,” was the response, “just see how splendidly she
is behaving. Ned, old boy, the Electric Monarch is a success. A bigger
success than we dared to hope.”

“She is indeed,” said Ned, almost reverentially, as he glanced down
from the pilot house window at the landscape flying by far below them.
It was his first experience in the air and he felt just a bit creepy
and scared.

But that feeling soon wore off, and before a glittering expanse of
water in the distance showed them that the ocean lay before them, Ned
Nevins, the virtual owner of the Electric Monarch, was at work on the
motors, oiling and adjusting as if he had been an engineer of a flying
ship all his life.

The motion of the craft was delightfully smooth and even. If it had not
been for the furious wind of the propellers, and the roaring of the
motor, it would have been difficult to believe they were moving at all.
Yet the speed indicator showed that they had attained a velocity of
fifty miles an hour and their maximum speed had not by any means been
reached.

Jack knew that with new machinery it would have been risking
over-heated bearings and all manner of engine trouble, to let the
Electric Monarch out to her full capacity.

Jack’s cheeks glowed and his eyes shone as the craft drove onward,
with his firm hands on the controlling wheel. It was invigorating
and blood-quickening to feel the way in which the Electric Monarch
responded instantly to every move of the controlling devices.

“Of course the Electric Monarch isn’t mine, nor have I any right to any
share in her but the builder’s, and yet I can’t help feeling that we
all have a part in her,” said the boy to himself. “That Jeptha Nevins
must have been a wonder. If he had only lived, this would have been a
proud day for him. He certainly left Ned a great legacy in those plans.
I wonder----”

Jack broke off short in his ruminations. The plans! It was true they
were in the safe at High Towers, but it was also true that just the
moment before sailing they had learned that enemies were interested in
securing them. Enemies backed by powerful interests, too, judging by
what Heiny Dill had said.

A troubled look crossed Jack’s face. His father was ill. In case
intruders gained access to the library, he could make but a feeble
resistance. But the next moment he dismissed the thought as ridiculous.
How could any one know where the plans had been placed? And even so, if
an attempt was made to blow open the safe, the servants would be bound
to hear.

“Just the same,” thought the boy, “I wish we’d notified the police
before we started.”

But at that moment a wind flaw struck the Electric Monarch and Jack’s
attention was fully occupied in handling the craft as she heeled over
like a ship in a heavy sea. When she was once more on an even keel, he
had other matters to occupy his mind.




CHAPTER XVIII.

NED’S TERRIBLE PERIL.


Beneath the Electric Monarch, soaring eagle-like far above it, a
glimmering speck against the blue, lay the Atlantic. The ocean was in a
calm mood. Viewed from above, its surface appeared to be as smooth as a
mirror.

But Jack knew that appearances were deceptive. The Atlantic is never
absolutely at rest. Even on the calmest days its bosom heaves with
long, swinging swells, running shoreward to break in heavy, thunderous
surf on the beach. He drew from a pocket beside the wheel the glasses
with which the receptacle was equipped.

Controlling the wheel with one hand, he raised the glasses to his eyes
with the other. He gazed downward through them and saw that the sea
was lazily swelling in long, oily combers, which could be ridden with
ease even by a cockleshell of a boat, whereas the Electric Monarch was
actually two capable cabin cruisers fastened together Siamese-twin-like
by ligaments of vanadium and steel and aluminum alloy.

“It’s safe enough to go down,” said Jack to himself and sounded two
blasts on the electric whistle.

This was the signal to the engineer to come into the pilot house for a
consultation. Ned soon presented himself. He was grimy but happy.

“How’s everything running?” asked Jack.

“Smooth as oil. You’d think the motors had been in commission for a
long time instead of being on their initial trip.”

“That’s good. I didn’t have much fear but they would work all right.
I’m going to try a drop, Ned.”

Jack watched Ned narrowly to see if the news had any effect upon him
but Ned simply nodded his head in a business-like way and remarked:

“Very well, sir.”

At this juncture there came a shrill whistle on one of the speaking
tubes leading to the helmsman’s wheel.

“Hullo, there’s Tom calling from the stern,” cried Jack, “wonder what’s
up now.”

He placed the tube to his ear and then gave an exclamation of concern.

“Oh, that’s too bad.”

“What’s the trouble?” asked Ned.

“Why, Tom has an attack of air-sickness. It’s pretty bad while it
lasts, but fortunately it is soon over. I’m going to call him in to lie
down in the cabin a while. Can you leave your motors and stand watch
astern, Ned?”

“Certainly. They’re all right for half an hour, anyhow. The current’s
fine.” The boy glanced at the indicator, which showed a strong, steady
supply of “juice.” Jack hailed Tom through the speaking tube and
ordered him to come in at once and lie down. He then hailed Heiny, who
by this time had gotten over his first scare, and told him to get some
hot coffee ready.

“Tom will be ready for duty before long,” said Jack, as Ned left the
pilot house, passing, as he made his way aft, Tom, who looked white
and ill. But he assured Ned it was nothing, simply an attack of
air-sickness which would soon pass over.

Ned took up his place in the stern between the two long supporting
frameworks of the rear propellers. The wind was terrific but otherwise
he felt no inconvenience except from the excessive vibration. He had
not been standing there more than a few minutes, keeping a watchful eye
all about him, when he noticed that the port stern bearing of one of
the propellers was beginning to smoke.

“Hullo! We’ll be having a hot box first thing we know,” said Ned to
himself. “I’ve got to oil that fellow and look sharp about it, too.”

He glanced out over the path he would have to travel. Ned was a plucky
boy, but he felt a qualm pass through him as he looked. The propeller
was fully ten feet out from the main structure of the craft and was
supported by a thin framework of braces.

The task in front of Ned was to straddle this framework and make his
way aft to the heated bearing, with nothing but 2,500 feet of space
beneath his shoe soles. For a minute he felt tempted to ask Jack for
instructions. But then his pride, always keen with Ned, came to his
rescue.

“I’ll do it,” he determined, taking a firm grip on his faculties. “But
it’s going to be some job.”

He gripped his oil can firmly, resolved to waste no more time. Then
clambering up to the framework, he straddled himself over the top part
of it, holding on to the lower part of it as best he could with his
feet.

It was like riding a bucking broncho in mid-air. The gale from the big
propellers swept around Ned like a hurricane. He felt his cap swept off
his head and dared not look downward to watch it go hurtling toward
the sea. He knew that the sight would be too much for his nerves.

Rallying himself with an effort, Ned began his dangerous crawl along
the framework. The further out from the main structure of the craft
he got the more nerve-racking became the task. The slender framework
shook and swayed as if it was determined to shake him off, and send him
flying into space.

Ned gripped his handholds till the paint flaked off on his palms. But
little by little he managed to work his way toward the bearing. The
propeller, a whirring blur before his eyes, dazzled him. The wind from
it seemed to catch his breath and jam it back down his throat. He clung
to his perch with the courage of desperation.

At last he reached a point from which he could reach the bearing. He
raised the oil cup and doused the smoking metal with oil. And then, his
duty done, he was horrified to feel a sudden wave of deadly nausea
sweep over him. The sea seemed to rush up toward him, and his senses
swam in a wild delirium.

“I must get back! I must! I must!” he said to himself, and then the
terrible grip of air-sickness descended upon him again and again, and
deprived him of all power to move.

Almost three thousand feet in the air, perched on a slender, bucking
framework, and a prey to the most severe form of air-sickness, Ned’s
position was perilous, indeed.

Suddenly he felt his senses leaving him. For a second he fought against
insensibility with all the power he possessed. But it overmastered him.
Ned felt his head swimming round and round like a detached body in an
aurora of blazing light. All at once something seemed to give way.

He felt himself falling! falling!

Then a blackness like night shut down upon him and he knew no more.

It was perhaps a quarter of an hour later when Tom presented himself to
Jack and announced that he was fit for duty.

“Very well, Tom, go back to your post and send Ned to resume his.”

Tom left the cabin. In less than ten seconds he was back. His face was
blanched and his lips white. Jack noticed he was trembling violently.

“What in the world is the matter, are you ill?” demanded Jack.

“No--no, it’s Ned.”

“What’s up? Anything the matter with him?”

“He’s--he’s g-g-g-gone!”

“Gone!”

“That’s right. I went aft and there was no sign of him. Joyce says
nothing has been seen of him up forward.”

“Great Scott!”

The boys faced each other with the fear of a great calamity on their
faces. If Ned was not on board he must have fallen from the Electric
Monarch while she was in mid-air. In such a case there was no need to
debate over the fate of the young comrade they had grown to love.

“I can’t leave the wheel, Tom, you must do what you can,” said Jack,
his voice trembling in spite of himself.

Tom stammered some reply and left the pilot house. He summoned young
Dill.

“Come aft with me,” he ordered. “We’re afraid an accident has happened.”

“An accidend! vot sort of an accidend?” blurted out the German youth.

“We’re afraid that Ned Nevins has fallen overboard.”

“Donnervetter!”

“You must keep a cool head, Dill, and do what I tell you.”

“I am as cool as a whole barrel of cucumbers,” was the reply.

“Then come with me. There’s one chance in ten thousand that he may be
on board and alive.”

Silently the two made their way aft along the heaving, swaying bridge,
a dreadful fear gnawing at their hearts.




CHAPTER XIX.

THE DISGRUNTLED CRONIES.


To say that the departure of the Electric Monarch from High Towers had
caused a sensation in Nestorville would be putting it mildly. The town
simply went wild.

School was dismissed, business came to a standstill, and the streets
were thronged from end to end with excited townspeople.

“What’s the trouble?” demanded Hank Nevins, as the waitress dropped
the plate of ham and eggs she was about to bring him and his worthy
companion, Miles Sharkey, and regardless of the crash and the spatter,
dashed into the street.

“Hark, what’s that they’re calling out?” cried Hank suddenly.

“Listen!”

Miles put down his knife and fork which he had grasped expectantly and
pricked up his ears. In another minute the cry,--which had grown to a
roar,--came to their ears with the distinctness of a thunder clap and
with much the same effect.

“Airship!--Airship!”

The cry reverberated through the village like a call to arms. Men
shouted and women screamed while small boys went charging up and down
with their heads in the air regardless of whom they bumped into.

“Great Juniper!” gasped out Hank, spilling his coffee in his agitation,
“do you suppose----?”

“I don’t suppose anything. Let’s make sure,” cried Miles.

Hatless they rushed into the street but nobody paid any attention
to their agitation. Everybody was equally excited. It was indeed a
thrilling sight. Far above the heads of the gaping crowd an immense
scarlet and silver shape was skimming on wings that shimmered in the
bright sunlight.

“Hurrah!” yelled a man, and a hundred took up the cry half hysterically.

“It’s flying!” cried out an old lady, as if there was any doubt about
it.

“What is it?” asked somebody.

“It’s an airship,” was the reply.

“Wa’al, it ain’t like any I’ve ever saw,” came the response. “It looks
as big as a house. It’s got cabins on it, too.”

“Must be some more of the work of them boys up at High Towers,”
hazarded Schultz, the blacksmith, who sometimes did odd jobs for the
boys.

“Like as not it is,” agreed somebody else. “Them boys ’ull break their
necks some day, sure.”

“You mean they’ll make Nestorville famous,” spoke up Schultz in the
capacity of the boys’ champion. “They’re the brainiest kids in America
to-day.”

“Oh, they don’t amount to very much,” came a sneering voice behind the
sturdy blacksmith.

He faced round instantly. The remark had come from Hank who, with Miles
at his side, was watching the successful flight with what feelings may
be imagined.

Schultz looked angry and was not afraid to let his irritation show.
Hank began to wish he’d kept quiet.

“What was that you said, mister?” asked the blacksmith.

“I just said anybody could do that who had the time,” said Hank,
modifying his speech somewhat.

“Well, you couldn’t do it, mister; it takes _brains_ to do anything
like that. That lets you out.”

The crowd in the vicinity began to titter. Hank hated being laughed at,
and his anger made him imprudent.

“That’s a stolen idea, anyhow,” he roared out at the top of his voice.
“The plans from which that airship was made belong to me.”

“Hush! Are you crazy?” exclaimed Miles, jerking Hank’s sleeve.

“No, I’m not! They do belong to me. That craft was designed by my
father, Jeptha Nevins, and I can prove it, what’s more.”

“If that’s so, why didn’t you build one yourself?” demanded Schultz.

“I didn’t have time to before thieves stole the plans. I’ll get even,
though. I’ll fix ’em. They won’t rob me!”

“For heaven’s sake, be quiet. Everybody’s looking at you. You’ll ruin
our plans.”

Miles Sharkey impatiently jerked at Hank’s sleeve. He would have liked
to put an emphatic hand over his noisy companion’s mouth. But Hank at
last saw reason. As the Electric Monarch soared off into the distance,
melting into the sky like a vanishing bird, he consented to allow Miles
to lead him away.

They had not gone very far when round a corner came Sam Hinkley. He was
out of breath and much excited.

“Did you see it?” he cried.

“See it? Do you think we are blind?” roared Hank. “What kind of
bungling is this? Didn’t you get the lever? How did they come to start?”

“Just what I’d like to know,” said Sam with equal heat. “I did my part
of the work all right. I detached the lever and hid it in an old well.
They must have had another one some place and put it on at the last
moment.”

“I guess that’s it,” said Miles pacifically, but Hank refused to calm
down. It galled his bitter nature to the quick to see the Electric
Monarch in successful flight when he had hoped and schemed for a
failure.

“I wonder what’s become of the Dutchman,” he snarled. “He’s ten times
brighter than you are, Hinkley,” which, as we know, was perfectly
correct, though not in just the way Hank meant it.

“How do I know where your Dutchman is,” growled Sam, “I tell you I’m
through with you. I risked a lot to steal that lever and this is all
the thanks I get for it. Gimme my money.”

Hank affected great surprise. So did Miles. They both stared at Sam as
if they thought he had suddenly taken leave of his senses.

“Money? What money?” exclaimed Miles.

“Why, the money for crippling the machine.”

A cunning smile crept over Miles’s face.

“Yes, the money for crippling the machine!” he sneered, “but you see,
my young friend, you didn’t do any such thing. In fact, for all we
know, you never went near it.”

“So you’re going to cheat me out of it, eh?” roared Sam. “But you
won’t. I’ll see the police, I’ll----”

But he stopped short as Miles burst into a roar of ironical laughter.

“See the police and tell them you didn’t get money for doing some
crooked work! You’re considerable of a fool, Sam Hinkley, but I guess
you aren’t fool enough for that.”

As this was so beyond doubt, Sam had to content himself with slinking
off, muttering threats about “getting even” which the two conspirators
did not much trouble themselves about. In fact they were beginning to
worry about young Dill. It was past the hour when he had said he would
meet them, and they began to feel uneasy.

It was as well for their peace of mind that they did not know the
true state of affairs, otherwise they would have suffered still more
perturbation of spirit.




CHAPTER XX.

TOM TO THE RESCUE.


With a feeling of anxiety such as he had never before known, Tom leaned
out over the stern framework. He had hazarded a guess that Ned might
have been rash enough to have attempted to gain the stern propeller
bearings.

But his surprise and relief were not any the less on that account
when he saw, lying limp and senseless across the slender stern shaft
supports, the body of his young chum, for such Ned had grown to be in
their weeks of work and association.

“Great Glory!” he exclaimed in his relief. “Heiny, hurray! he’s alive.
Had an attack of air-sickness I guess, and it’s knocked him out.”

But in the midst of his jubilation came another thought,--a reflection
that sent the hot blood curdling like ice water through Tom’s veins.
Suppose the boy were suddenly to regain consciousness and, not
realizing where he was, attempt to raise himself? In such a case he
must inevitably be dashed to death through space.

Still further reflection, after the first gush of his joy at finding
his comrade alive had subsided, convinced Tom that to get him on board
from his perilous position would be no mean undertaking in itself. Ned
lay some eight feet out from the end of the “running-bridge.” His inert
form was balanced across the swaying, vibrating framework. Would that
framework--it looked as slender as a spider’s web--bear the weight of
the two boys?

Tom thought it would. He knew the care with which every section of the
Electric Monarch had been constructed. Every rivet and bolt in her had
been tested and retested to three times the strain that would be placed
upon it.

“I’ll risk it,” decided Tom. “Here, Heiny, hold my coat.”

He stripped off his khaki Norfolk swiftly and handed it to the German
who, too stupefied by the sight of Ned’s perilous position to say
anything, stood gaping, open-mouthed, powerless to speak or move. He
took Tom’s coat mechanically. Then speech came to him.

“Vot you do, hein?”

“Can’t you see I’m going out there to get Ned on board again?”

“Himmel! You preak your neg.”

“I don’t think so.”

So saying Tom cautiously got astride of the framework, and began
worming his way toward Ned’s still form. It was terrible work, but Tom
knew that the return trip would be still more accompanied by peril.
Steeling himself to the task in hand, he worked slowly forward while
Heiny stood petrified watching him.

Foot by foot, or inch by inch, as it seemed to Tom, he drew closer to
the form of the boy he had come to rescue. At last he could touch him
and look into his white face.

The boy lay as limp as a bundle, and in Tom’s eyes it was better so. It
made his task so much the easier. He extended his hands and got a firm
grip on Ned’s body.

Then he began to work his way backwards. It was agonizing work. In
order to keep Ned balanced on the narrow strut, he was compelled to use
only his feet to steady himself. Both hands were required to hold Ned
on the perilous perch. Tom dared not look downward. The thought of the
profundity of space that lay beneath them made him sick and dizzy.

Tom could never tell just how that journey was made. It was only a few
feet, but it seemed like so many miles. Ever present in his mind, too,
was the danger of Ned’s regaining consciousness and making some sudden
move. In such a case they might both be doomed to death.

[Illustration: He extended his hands and got a firm grip on Ned’s
body.--_Page_ 190]

The wind from the propellers blew against Tom with vicious intensity.
His legs ached as if they would drop off, for he had them alone to
depend on both for balance and motion. But at last, somehow or other,
he came within reach of Heiny Dill’s grasp.

The German lad was ready. As Tom felt the last ounce of his strength
oozing from him he felt, too, a strong grasp on his shoulders.

“Stetty! Stetty!” came a voice in his ears.

“I’m all right,” muttered Tom thickly. He helped Heiny drag Ned in to
safety and then he, too, almost gave out. But he knew that Jack in
the pilot house would be eagerly awaiting news. So putting aside his
weariness he seized the stern speaking tube and sent the good news
to the young commander. This done, Ned was taken to the cabin and
restoratives administered from the Electric Monarch’s medicine chest,
with which she had been provided in the anticipation that some day the
boys might want to take a long voyage.

Ned, who was naturally full of vitality, was soon himself again and
insisted on taking his watch at the motors. As for Tom, his buoyant
nature took even less time in recovering from the strain that had been
put upon it. We will leave it to the imagination what the boys had to
say to each other when Ned learned that it was Tom who had saved his
life at the risk of his own.

Not long after this Jack, who had taken the craft quite a distance out
to sea, determined to turn back landward and make a swift flight home.
He judged they had done quite enough to prove the Electric Monarch’s
worth and in this the others agreed with him.

They were perhaps a mile off the shore when Joyce, on the lookout
forward, gave a sudden sharp hail through the speaking tube.

“Ship below us, sir.”

“What is she?” hailed back Jack.

“Looks like a steamer. Passenger boat, I guess.”

“I reckon I’ll give her a call,” said Jack to himself as he hung up the
tube. “My! won’t her passengers be surprised, though.”

He took out the binoculars and had a look at the steamer Joyce had made
out. She was a fair-sized vessel with one black funnel amidships. Her
white upperworks showed she was a passenger craft.

Jack hailed Ned Nevins on the engine platform.

“Put on your best bib and tucker, Ned, we’re going calling.”

“Calling!” came back the astonished exclamation.

“Yes, deep sea calling. Hail Tom and tell him to look his prettiest.
Too bad we didn’t bring any cards.”




CHAPTER XXI.

SALUTING A STEAMER.


The Electric Monarch gave a dive and a swoop that caused all Heiny
Dill’s qualms to come back tenfold.

“Himmel! Ve are sinking. Man der boat-lifes!” he yelled, but nobody
paid any attention to him and he speedily recovered his equanimity, and
with his rotund face poked out of the cabin port watched, with as much
interest as any one else on board, the approach of the steamer.

“She’s a Boston and Portland liner bound north,” declared Jack to Ned
Nevins who, as the motor did not need any attention just then, stood at
the young skipper’s side in the pilot house.

“How can you tell?”

“By her smokestack. Black with a white band.”

On came the steamer as the Electric Monarch swooped downward in a
graceful curve to meet her. As the hydroaeroplane commenced her
dive, there burst from the steamer’s whistle a jet of white smoke.
Immediately after, the boys heard the booming greeting of the vessel’s
siren.

Jack pressed the button that controlled the Electric Monarch’s siren
and the next moment the hydroaeroplane was screeching an answering
salute. They were now quite close to the steamer and could see her
uniformed officers on the bridge and her decks black with passengers,
their upturned faces looking like white discs.

“My! I’ll bet there’s a tall lot of speculation going on on board that
craft right now,” said Ned, as the two boys gazed downward.

“I guess you’re right. It isn’t every day that the passengers of a
liner have a chance to see a craft like this in action,” was the
response.

Excitement did, indeed, appear to be rife on board the craft beneath
them. Passengers could be seen clambering to all sorts of points of
vantage. Handkerchiefs were frantically waved and the ship’s whistle
was kept constantly roaring salutes.

Astern of the Electric Monarch fluttered the Stars and Stripes. Jack
snatched up the speaking tube connecting with the stern lookout post.
When Tom responded he ordered him to dip the colors in response to the
steamer’s salutes.

A few moments afterward Jack and Ned saw the liner’s ensign glide
slowly down the jack-staff and then ascend again as she acknowledged
the mid-air courtesy.

“Can’t we turn and follow her?” asked Ned, as the steamer, with a great
creamy bow wave curling away from her sharp cutwater, sped on her way.

“Certainly. For a short distance, anyway. We might as well show them
our paces.”

Jack swung the Electric Monarch in a sharp circle and they could
feel the equilibrium devices grate and vibrate as the big craft was
“banked” at a sharp angle. By this time the steamer had put quite an
interval between herself and the Electric Monarch. But Jack let the
hydroaeroplane out a notch more than he had been doing.

The Electric Monarch answered the quickened impulses of her propellers
like a race horse. In a flash, as it seemed, she was once more abreast
of the steam vessel.

“Look,” cried Ned, suddenly, “there’s a man clambering up on the
jack-staff.”

The venturesome passenger had gained the stern railing. He hopped
to the top of it and then began to swarm up the jack-staff from the
summit of which fluttered the flag. Holding on with one hand he waved
frantically with the other. The boys were in the act of acknowledging
the salute when Jack gave a sharp cry.

“Gracious! He’s overboard!”

Like a stone the man had suddenly dropped from the jack-staff into the
swirling water astern of the steamer. How he had lost his hold was a
mystery. It all happened in a flash. One second he was waving, the next
they saw him falling down into the sea and then the waters closed over
him.

The steamer’s whistle sounded in short quick jerks. It was the signal
to man the lifeboats. The boys could see the passengers and the crew
rushing about in seeming confusion, but in the case of the latter, as
they knew, the apparent chaos represented order.

And now, amidst the white, boiling wake of the vessel, they could make
out the dark speck of a man’s head. He was swimming for his life,
swimming desperately to avoid being drawn into the suction of the
propeller. Jack’s hand sought a lever.

Ned looked at him questioningly. But he did not speak. He was pretty
sure in his own mind what the young skipper of the Electric Monarch was
going to do.

This belief was speedily verified. Jack drew back the lever and the
planes took a downward slant. Simultaneously Jack flashed on the red
lights that signaled to the stern and bow lookouts that a descent
was to be made. Joyce in the bow and Tom in the stern had seen the
accident, but of course had not left their posts. The flash of the red
lamps at their stations apprised them that the Electric Monarch was
about to make her first essay at saving life.

Down shot the big craft with a swiftness that made it seem as if she
must inevitably shoot straight to the bottom of the sea. Even Ned,
secure as he felt while Jack had the wheel, flashed a doubtful look at
the young skipper. But he said nothing and the next moment he was to be
glad that he had remained silent.

With iron nerve, Jack allowed the Electric Monarch to drop like a
swooping fish eagle, and then, without the quiver of a muscle, he
turned apparent disaster aside with a swift manipulation of the
leveling lever. The bow of the Electric Monarch raised and struck the
water at an angle that caused her to glide along the surface much as a
newly launched vessel might take to sea.

It was a masterly bit of handling. The spray flew high above the
Electric Monarch, completely hiding her for an instant from the view of
those on board the steamer. A great cry went up when it was seen that
she was safe and riding like a duck on the heaving surface of the sea.
To many of those on board it had appeared as if the big craft must have
sunk. Their relief expressed itself in a mighty cheer.

Those on board the Monarch felt no less relief. Tom and Joyce had stuck
grimly to their posts but both had felt their hearts beat quicker as
they neared the water. As it was, a good drenching was all they had
received, and they had but scant time to give any attention to that,
for Jack instantly headed the Electric Monarch in the direction in
which the bobbing head of the swimmer had last been seen.

Presently Ned gave a shout.

“There he is!”

Sure enough, not twenty yards from the Electric Monarch as she lay on
the waves, was the form of the swimmer.

“Stick it out! We’ll get you!” shouted Tom, from his post astern.

The swimmer waved a confident hand in reply. He did not appear at all
incommoded by his accident. On the contrary, he was swimming leisurely
as if he rather enjoyed his bath than otherwise. The boys gazed at him
in astonishment. Within the next few minutes they were destined to be
yet more surprised.




CHAPTER XXII.

AN OLD FRIEND.


The surprise in store for them was this. The swimmer was an old friend
of theirs.

“Captain Sprowl!” shouted Jack, as they neared him.

“Aye! aye! my hearty!” came back the response, in the old New
Englander’s hearty voice, “lay alongside and I’ll come aboard.”

“What, you know him!” demanded Ned.

“Do we? I should say so. He was in command of Professor Dinkelspeil’s
yacht when the mutineers sunk her. After that he was with us all
through that Amazon country I told you about.”

But it was no time to enter into explanations. The Electric Monarch was
skillfully maneuvered alongside the doughty old mariner before the
boats from the steamer had fairly left the vessel’s side. Tom, who had
also recognized Captain Sprowl, ran forward from his post in the stern
and threw him a line. Five minutes later they were all standing in the
pilot-house listening to the captain’s story of how he had come to
loosen his hold of the jack-staff and plunge into the sea.

“You see, my hearties,” he said, “I was sure it was you in this here
sky-hooting, sea-scooting contraption and so I says to myself, ‘I’ll
give ’em a proper salute, I will, ship-shape, man-o-war fashion.’”

“Well, you certainly did, Captain,” laughed Jack, “but what in the
world were you doing on that ship?”

The captain looked knowing.

“I am on my way to Portstown, Maine,” he said. “There’s a big fair
there next week and one of the features of it is to be an aerial
carnival. I’m to be in charge of the airship part of it and I’ve booked
some of the best aviators in the country.”

The boys looked interested. Anything to do with airships always
appealed to them.

“It’s just come to me,” resumed the captain, “that maybe you’d like to
bring this contraption up thar’ and try for some of the prizes. What do
you say?”

It was characteristic of Captain Sprowl that, regardless of his wet
clothes and recent narrow escape, he made no more of it than if
everything was all right and he had come on board the Electric Monarch
in quite the ordinary course of events.

“Well, you see, Captain, this ship, the Electric Monarch we call it,
isn’t ours at all. It really belongs to Ned Nevins here.”

“That is, a share of it does,” spoke Ned modestly.

“Well, what does Ned say?” inquired the captain, as Heiny entered the
pilot house with steaming hot coffee which Jack had ordered got ready
as soon as they struck the water.

“Ned says--yes!” responded the lad, “but how about you, Jack and Tom?”

“So far as I’m concerned I think it would be a splendid thing,” said
Jack. “It would give us a chance to try out the Electric Monarch in
competition with other air craft, and then, too, the voyage up there
would put her through her paces in great shape. My answer is--yes.”

“Same here,” declared Tom with positiveness.

“Ches, dot suids me,” said Heiny, balancing his tray like a born waiter
while the captain gulped down his steaming coffee.

“Then we’ll call it settled,” said the captain. “I’ll send you entry
blanks on my arrival at Portstown. Be ready to start as soon as
possible.”

“Don’t worry about that, Captain,” said Jack, “we certainly shall be
ready.”

By this time the boats from the steamer had come alongside and the
singular interview had to be concluded.

“Well, I think it is safe to say that a business deal was never
conducted under more curious auspices than this one,” laughed Jack, as
the captain prepared to board one of the boats. “I guess you’d be ready
to talk business if you fell out of a balloon, Captain.”

“If there was an undertaker handy, I would,” said the captain. And with
a cheerful wave of his hand, the stout old seaman stepped into a boat
and was rowed back to the steamer.

As the vessel got under way again the Electric Monarch took to the air,
rising as easily from the water as she had from the land. With parting
cheers and mutual salutes the two craft parted, the steamer to resume
her northward voyage, the Electric Monarch to turn homeward after an
eventful trial trip which, so far as the boys could see, had been a
success in every particular.

On the homeward voyage some brisk breezes were encountered, but the
Electric Monarch behaved splendidly. A short distance outside the
village of Enderby, Jack, who had surrendered the wheel to Ned, in
order to initiate him into handling the craft that bore his name, spied
a black dot in the distance.

It was high in the air and traveling rapidly toward them. It was some
minutes before they made out what it was.

“A balloon!” They all made the discovery simultaneously. The big gas
bag was traveling fast and on a course which would bring it across the
Electric Monarch’s bows. As it came closer they saw that it was 
a brilliant red and bore on the sides of its gas bag in huge letters,
“New Yorker.”

“Why, that’s one of the balloons that went up in that contest at New
York,” cried Jack. “They started from Brooklyn last night. My! they’ve
made good time.”

On came the balloon, driving fast. In it were two men clad in khaki
and wearing close-fitting caps. They waved frantically to the lads in
the Electric Monarch and the hydroaeroplane was brought close alongside
the balloon, keeping up with it easily.

One of the men in the balloon basket snatched up a megaphone. Placing
it to his lips, he shouted:

“Ahoy! what craft is that?”

“The Electric Monarch of Nestorville, Mass.,” rejoined Jack, in true
air-sailor fashion. “What craft is that?”

“The New Yorker, of New York, pilots Augustus Yost and Alan Frawley,
will you report us?”

“We sure will. When are you coming down?”

“We don’t know. This is an endurance race--we’ll keep up as long as
possible. Good-bye.”

“Good-bye,” and so ended a scene which ten years ago would have been
scoffed at as impossible, yet it was only the other day that newspaper
readers perused the account of an aeroplane towing a disabled dirigible
into her hangar.

But we must now hasten home to High Towers with the boys. They arrived
there without further incident, having made excellent time. The workmen
who had been left behind were there to help them make a landing, and
once more the Electric Monarch rested on dry land.

Hardly had she touched the ground, however, before Jupe was seen
running from the house at top speed. He was shouting something, but
till he got close by they could not make out what it was. Then his
words became clearer.

“It’s my father!” cried Jack, in an alarmed voice.

“What can be the matter?” cried Tom.

“I don’t know, but it must be something serious,” declared Jack, with a
pale face, as Jupe came panting up.

“Oh, Massa Jack,” he wailed, “yo’ fadder am turrble sick, sah. Dey
heard de bell ring an’ hurry up to der liberry. Dey foun’ him lyin’ on
de flo’ widout his senses.”

“Gracious!” cried Jack, “we must hurry to the house at once.”

“An’--an’ dat ain’ de wustest,” stammered out Jupe.

“Well, what else?”

“De do’ ob de safe done be open an’ it look lak’ some papers bin done
taken out!”




CHAPTER XXIII.

THE LOST PLANS.


But, for the time being, the condition of the safe did not occupy any
place in Jack’s thoughts. His sole care was for his father. Hastening
to the house at top speed, he found that Professor Chadwick had been
placed in bed and a physician summoned.

The doctor was coming out of the room just as Jack, with a pale,
agitated face, came flying in.

“Oh! Dr. Goodenough,” he exclaimed, “how is dad? What has happened?”

“Be calm, my lad,” said the doctor kindly, placing a hand on the
excited boy’s shoulder. “Your father has suffered nothing worse than
an attack of vertigo brought on by overwork and study. A few weeks’
quiet will make him perfectly well again, and then I shall forbid him
overexerting himself.”

“Can I see him?” asked Jack eagerly.

“Not just now. He is still only partly conscious. From what I can
gather, the servant who answered the bell found him lying on the floor
of the library unconscious. He was carried to his room, and I was sent
for at once.”

“When can I see him?” demanded Jack anxiously, and Tom, who had now
arrived, repeated the question.

“Probably this evening, when I shall pay another visit.”

“He is only suffering from vertigo, doctor?” asked Jack, with curious
insistence, “not from any--any injuries?”

“Injuries? I don’t understand you.”

“He had not been in any struggle, then? That’s what I mean.”

“Of course not. What an odd question!” The doctor looked at Jack
quizzically. “I shall have you under my care next,” he said jokingly.

“I thought that perhaps----”

Jack hesitated.

“Go on, my lad. I can see there is something on your mind. What is it?”

“Just this, doctor. Old Jupe, our <DW52> man, told me that the door
of the library safe, in which some valuable papers were deposited, was
open when my father was found.”

The doctor’s face grew serious.

“I knew nothing of this,” he said. “Were there any signs that a violent
entry had been effected?”

“That I don’t know, doctor. Naturally I came here first to find out my
father’s condition.”

“It need give you no worry, my boy. I can assure you of that. Let us
go to the library at once. What you have just told me may place a very
different light on the matter.” And the doctor’s face grew serious.

“How is your father, Jack?”

Jack turned, and saw Ned Nevins, who was, by this time, one of the
household, at his elbow. The boy’s face was troubled, for he had a
genuine affection and regard for the good Professor.

“He has simply had a stroke of vertigo. It is nothing serious, Dr.
Goodenough says. But, Ned, the safe----”

“I know. I heard what Jupe said.”

“Ned, the papers--your papers--may be stolen. How can I----”

“Say nothing about it, Jack. So long as your father has not been
injured I do not care. Do you think that gang of rascals would have
dared to break in here?”

“We can’t tell anything till we have examined the library. We are going
there now. Come along.”

In the library everything was in order. The servant who had answered
the bell was summoned and declared that things were exactly as they
were when she replied to the Professor’s summons. He was lying at the
foot of a desk when she entered the room and was quite unconscious.

“Let us examine the safe,” said Dr. Goodenough.

The door of the safe was ajar, and the servant declared that it had
not been touched by any one since the discovery of the Professor’s
unconscious form.

“You are quite certain of this?” asked the doctor.

“Oh, yes, sir. Positive.”

“Jack, where were the papers put?”

“In a drawer inside the safe, doctor.”

The boy had swung the door of the safe open, and the next instant he
turned a white, startled face on the others.

“The drawer is empty. It has been robbed!” he exclaimed excitedly.

“Keep cool, my boy,” admonished the doctor. “You are sure the safe was
closed when you left?”

“I shut it myself, doctor. There is not a chance that I could be
mistaken.”

“And the combination?”

“I gave it to my father with my own hands. It was the last thing I did
before I left.”

“Then the safe could only have been forced open unless some one
possessing the combination opened it.”

“That is the only way any one could have gained access to its contents.”

“And yet there is not the slightest evidence that these doors have been
forced,” said the doctor, who had been examining the safe. “This is a
most mysterious occurrence.”

“How could the robbers have opened it?” demanded Jack.

“How did they get in, anyhow?” Tom wanted to know. The boy had been
looking about the room. “This window is closed and locked with a
snap-lock on the inside. Uncle must have felt chilly and closed it, or
was it shut when you left, Jack?”

“It was shut,” said Jack positively. “I recollect that, because I asked
dad if he didn’t want it closed, and he asked me to shut it.”

“There’s soft mould in the flower bed outside,” struck in Ned. “If any
one had come in that way they must have left their footprints on the
dirt.”

“That is so,” agreed the doctor. “Let us look at the ground outside the
window.”

But an examination of the flower bed only deepened the mystery. It was
a bed about five feet wide, and there was no possibility of any one’s
having stepped across it without leaving the imprint of his feet. It
had rained two days before, too, so that the ground was moist and would
have readily retained any impression.

Yet there was not the slightest trace of a footprint to be seen. The
little group exchanged puzzled glances.

“Perhaps somebody got in by the front door,” suggested Jack, but on
inquiry it was learned that Jupe had been busy polishing floors in the
front part of the house most of the day, and nobody could have got past
without being seen. The only other entrance to the house was by the
kitchen, and the cook was certain that nobody had come in through her
domain.

As a last resort they examined the scuttle on the roof. It locked on
the inside, and the fastenings had not been tampered with. Completely
nonplussed, the investigators halted and talked matters over. Dr.
Goodenough eventually decided to question Professor Chadwick that
evening if he should be strong enough.

As may be imagined, the mystery of the theft of the papers cast a gloom
over the household. Jack felt that he was partly responsible, and said
so to Ned Nevins. But the latter indignantly bade him to say nothing
about it.

“Let us be glad that the robbers did not injure your father,” he said.
“The plans are gone and that is all there is to it.”

“But if they are not recovered, Ned, how can we ever make restitution
to you?”

“If they are not recovered we still have the Electric Monarch. We must
hurry and draw up another set of plans based upon her structure and
rush them through the patent office.”

“That’s about the only thing to do,” agreed Jack ruefully, “but I can’t
tell you how bad I feel, Ned, over the loss of your property which you
entrusted to our care.”

“Forget it,” said Ned boyishly, and, although the expression was
slangish, it conveyed to Jack a sense of consolation, for he felt that
Ned would never blame him for the loss of Jeptha Nevins’s lifework.




CHAPTER XXIV.

A BAFFLING ROBBERY.


Dr. Goodenough’s visit that night did not serve to throw any light on
the mystery of the safe robbery. In the meantime the police had been
summoned, and investigated the premises without getting any nearer a
solution of the puzzle than the boys and Doctor Goodenough had done.

Jack had taken it upon himself that afternoon before supper to
telephone to the Hinkley House. He learned there that Sam was out and
not expected back for some time. Heiny Dill was dispatched to the
village to learn further particulars, and returned with the report that
Hank Nevins and Miles Sharkey had both left the Hinkley House shortly
before his arrival on the scene.

The young amateur detective had trailed them as far as the depot, only
to find that they had taken the train bound south a few moments before
he arrived. He had learned, however, that they had spent most of the
day previous to their departure in the hotel. This only served to make
matters the more baffling.

By common consent, whether justly or unjustly, the boys had been
inclined to suspect either Hank or Miles with being concerned in the
robbery. But it seemed that they had a complete alibi. Sam Hinkley,
too, had been seen about the village on and off most of the day, and
thus he also was eliminated. But the boys had not suspected Sam in the
matter, anyway, so this information was not a surprise to them.

“This is a mystery for fair,” declared Jack, when Heiny Dill had duly
reported the facts to him. “Fellows, we are stumped.”

“Possibly to-night your father will be able to talk and throw some
light on the matter,” suggested Ned.

“Perhaps so. I am sure I hope that he will. A mystery like this gets on
your nerves. The only people I can think of who knew of the existence
of the plans, except ourselves, are Hank and his friend Sharkey. From
what you say of them, Ned, I guess they wouldn’t stick at anything;
from what Heiny Dill has found out we know it was impossible for them
to be here at about the time of the robbery. Dad was found unconscious
about an hour after we left. At that time Hank and his friend were in
the village. They were seen there talking to Sam Hinkley.”

“If we could get hold of Sam maybe he could tell us something,”
suggested Tom.

When Dr. Goodenough arrived that evening he informed Jack that
Professor Chadwick had sufficiently recovered to be able to talk. With
what eagerness they all awaited the outcome of that interview may be
imagined. But so far as helping to clear up the mystery was concerned,
Professor Chadwick was as powerless as any of them.

“After Jack had closed the window and left,” he said, “I lay down
upon the lounge. After a time I felt better and thought I would get
a book. I rose from the couch and went toward the bookcase. I can
recollect nothing more till I found myself in bed with Dr. Goodenough
in attendance on me.”

“Nothing else at all?” gently urged the doctor.

“Nothing except that Jupe came in to tell me that the Electric Monarch
had started successfully on her maiden voyage.”

“You can recall nobody attempting to force the window or open the safe?”

Professor Chadwick shook his head positively.

“Nothing like that at all, doctor,” he said, with conviction.

“And nobody but Jupe entered the room, to your knowledge?”

“Nobody,” declared Professor Chadwick, “and I think we can safely
leave Jupe out of the question.”

Late that night Jack called up the Hinkley House and discovered that
Sam had not returned.

“I thought he was up to your place,” said Landlord Hinkley. “I’ve no
idee whar’ the boy hes gone. He ain’t often out this late at night. I
hope he ain’t up to any monkey shines. If he be, I’ll whale him good,
big as he be.”

Jack decided that it was no use telling Sam’s father of all that had
occurred since the morning. But when he hung up the receiver he was a
sadly perplexed boy. When Heiny Dill departed for the hotel that night
he promised to find out what he could. On his return the next morning
he reported that a wire had been received from Sam, who said that he
was going to New York. Landlord Hinkley found, incidentally, that the
funds to finance Sam’s journey had been taken from his cash drawer.
This was the sum total of young Dill’s information, and it was not
enlightening.

In fact, it complicated the puzzle, for if Sam was not implicated in
the robbery, and there was nothing to make them believe that he was,
there was no apparent reason why he should decamp so suddenly, unless
he feared that he might be prosecuted for the theft of the lever. The
boys, therefore, were forced to conclude that this was the reason for
Sam’s flight.

As for the sudden departure of Hank and Miles Sharkey, that was more
understandable. They had practically hired Sam to make his desperate
attempt to <DW36> the Electric Monarch, and knew that their plans
must have been foiled when they saw the craft take to the air. This
being so, they had probably argued that Sam would be arrested and would
implicate them. Flight, then, must have seemed to them to be their
wisest course.

And so, for the present, the mystery of the stolen plans had to be
given up by the police and those most interested in the recovery of the
papers, as an unsolvable puzzle. Of the startling way in which it was
to be cleared up, none of those concerned had the slightest inkling.
From day to day the boys feared to hear of the plans being filed in the
patent office. But, although through Prof. Chadwick’s patent lawyers
in Washington, they kept in constant touch with the National Capital,
no such papers turned up. In the meantime the boys busied themselves
making as complete a set of duplicate plans as possible, covering every
patentable feature of the Electric Monarch.




CHAPTER XXV.

OFF TO THE FAIR.


Two days after the mysterious disappearance of the plans of the
Electric Monarch the promised entry blanks for the Aëro Carnival at
Portstown arrived. Inclosed with them the worthy captain had sent a
copy of a Portstown newspaper in which there was announced in flaring
capitals the following:

“Captain Abe Sprowl, in charge of the Aëro Carnival, announces that
he has engaged, at unprecedented expense, the newest marvel of the
air, the motor-driven hydroaeroplane, The Electric Monarch, owned and
invented by Ned Nevins, the youthful inventor. The machine will make a
flight from Nestorville to the show grounds, and will be on view daily
during the carnival.”

“Well, what do you think of that?” gasped out Jack, as he read this
flamboyant announcement out aloud to his companions. “As a press agent
Captain Sprowl is certainly a wonder. It looks as if we’d have to go
now, boys, doesn’t it?”

“It sure does,” agreed Tom, “but I wish he hadn’t run that fool notice.
We don’t want all that notoriety just now.”

“No, indeed. Not till the plans are all safely filed in the patent
office,” agreed Ned, with a serious look. “Queer, that whoever took the
other set hasn’t tried to place them on record yet, isn’t it?”

“Yes, I can’t understand it,” agreed Jack; “it looks as if they had
something up their sleeves that we know nothing about. However, there
is no use worrying over it. I guess we ought to be thankful that things
are as they are.”

Heiny Dill arrived a few moments later. In honor of his new job he had
purchased a more flaring tie than ever, and his socks were of a lurid
purple.

“Any news of Sam, Heiny?” inquired Jack, as the young German sauntered
up, whistling blithely, to where the lads stood grouped about the
Electric Monarch, on which some minor adjustments were being made.

“Nodt a vord,” responded young Dill, “he hass made idt a vanishment as
if he hadt dropped der eardt off.”

“Well, I don’t hear any complaints about his absence,” declared Tom.
“So far as we are concerned we don’t care if he never comes back. I’m
sorry for his father, though.”

“Veil, der oldt man is bearing oop midt remargable composure alretty,”
declared Heiny, cocking his head on one side and giving a “yodle” more
remarkable for vigor than harmony.

“When do we start, fellows?” asked Jack that afternoon when he had
filled out the entry blanks and they had been mailed by Heiny Dill.

“The Electric Monarch is ready to go this minute,” said Tom. “I was
just talking to Joyce.”

“Then what do you say about to-morrow?” asked Jack.

“Suits me,” said Ned, who wanted nothing better than to be riding in
the Electric Monarch again.

“Me, too,” said Tom. “I’m tired of being on _terra firma_.”

So it was arranged that the start for the Portstown Fair should be made
the next morning. Professor Chadwick was still too weak to attempt to
accompany the boys, but he wished them all sorts of luck and a good
time.

“We’re sure to have a good time, anyhow,” Tom assured him.

Till late that night the boys worked on stocking up the larder of the
Electric Monarch with all manner of canned foods. Heiny Dill, who was
as fond of good things as most boys, watched these preparations with
glittering eyes. He smacked his lips visibly as he stowed away the
provisions on shelves in his domain.

The boys slept little that night, awaking early to find it a slightly
overcast morning with a promise of fair weather later on. There was but
little wind, however, and everything appeared to be propitious for a
speedy, uneventful voyage to Portstown.

Before leaving, Jack affixed to the “navigation-desk,” in the pilot
house, an “aërial map” of the route. This was a map on which various
landmarks, easily discernible from a height, were noted down, and it
was issued by the Aëronautical Society of America. Maps such as these
are of the utmost use to airmen who naturally would find little to
guide them in an ordinary map or chart. Marked in red ink on the aërial
map were various arrows showing the probable direction of the wind in
crossing various bits of high ground or in passing over cities.

The air is by no means, as might be imagined, a smooth road to travel.
It is full of “billows,” aërial “cliffs” caused by up-drafts, and vast,
empty pockets wherein nothing but a vacuum exists, and which many
airmen claim are the greatest source of danger to aviators that the
atmosphere contains.

As there was nothing to cause delay, the Electric Monarch’s motors were
started spinning almost as soon as it was broad daylight. Everything
proved to be in perfect order, and after the tuning-up process the
boys took their stations on the craft. As before, Joyce had the bow
lookout and Ned Nevins alternated between the pilot house and the
motor-platform.

Professor Chadwick and Jupe waved them farewell as they shot upward,
and before very long the village of Nestorville and High Towers lay far
behind them. Jack sent the Electric Monarch straight up on an inclined
aërial staircase till she had gained the height of five thousand
feet. At this altitude they proceeded steadily along, the height being
sufficient to avoid any danger from upward thrusting air currents.

The morning passed uneventfully, and shortly before noon Heiny Dill
announced that lunch was ready. They took this in relays, Ned relieving
Jack at the wheel while the young skipper ate. They passed over several
towns and small villages, and through the glasses they could plainly
see the flurry they were causing down below. It amused them to watch
the scurrying atoms which they knew were human beings rushing about and
pointing upward as the Electric Monarch passed high above their heads.

Not long after lunch, as they were passing over what seemed to be a
large farm, they saw several men running along below them. Suddenly
one elevated and aimed a gun at the fast flying craft. Of course the
Electric Monarch was far too high for the charge to reach her, but the
boys could see the puff of smoke that accompanied the discharge, and
knew that if they had been lower they would have felt shot pattering
about them.

“That’s a specimen of what Atwood, the trans-continental flier, had to
contend against,” said Jack. “The more ignorant people are, the more
they dislike to see modern inventions. I’ll bet if that fellow with the
gun could have hit us he would.”

“His intentions seemed serious, anyhow,” laughed Ned, “but the Electric
Monarch is a hard bird to bring down.”

About an hour later Jack decided to drop down closer to the earth. He
wished to test the effect of the currents near to the heated surface on
the Electric Monarch. Accordingly the craft was brought down till at
times she was rushing along at not more than two or three hundred feet
from the earth.

They were flying over a large, prosperous-looking farm at a fair rate
of speed when there came a sudden check in the air craft’s movement.
She plunged violently and pitched forward as if about to capsize.

“It’s the grapnel line!” shouted Ned, “it’s gotten loose and hooked on
to the roof of that barn!”

At the same instant there came a sound of rending and tearing wood as
the steel points of the grapnel dug into the roof of a rickety old barn
and tore it loose from the rafters. Jack acted like a flash. He set his
descending planes and came to earth in a beautifully executed dive in a
stubble field just beyond the farm buildings.

“The grapnel must have torn loose from its fastenings,” he said; “lucky
it was no worse. As it is----”

He broke off short. Running toward them from the farmhouse came the
farmer and two of his hired men. The farmer carried in his hand a
formidable looking gun. As he drew close to the boys he leveled it at
them. At the same time he cried out angrily:

“Stay right where ye be. Don’cher move, doggone yer, er I’ll shoot.”

The look in his eye, as well as the menace in his voice, convinced
the boys that the threat was no idle one. The man was thoroughly
angry over the accidental damage to his barn. On he came with leveled
gun, shouting threats, while the two hired men kept up a steady
accompaniment.

“Well, this is a fine fix,” commented Jack. “I guess we’ll have to
settle for that roof before we leave here.”

“You kin jes’ bet ye’ll hev ter,” roared the farmer, who had overheard
him.




CHAPTER XXVI.

AN UNLUCKY MISHAP.


“That’s all right, sir. We’re willing to pay you whatever is right for
the damage we have done,” said Jack, in as pacific a voice as he could
assume.

“Fine times these be when a passel of kids kin come along in a flyin’
contraption an’ take off a man’s roof!” exclaimed the angry farmer, far
from being pacified.

“It was an accident,” declared Jack; “we are just as sorry for it as
you are.”

The farmer in his rage had paid not the slightest attention to the
Electric Monarch, but his two hired men stood looking at it with open
mouths. They had never seen anything like it, and the farmer’s orders
to them to “close up” fell upon deaf ears.

“Accident be dol-dinged,” exclaimed Farmer Turpin angrily; “it warn’t
no accident. You done it a-pupose.”

“We certainly did not,” replied Jack, with some heat. “Do you suppose
we’d want to wreck our craft for a rotten old roof?”

“Rotten old roof!” bellowed the farmer furiously. “I’ll show yer how
rotten it was. It’ll cost yer a hundred dollars fer ther damage you’ve
done.”

“Ridiculous,” said Jack, who had been looking at the damaged roof. It
was old and moss-grown and had covered one of the oldest buildings on
the farm.

The boards of the antiquated structure were split and paintless. Wind
and weather must have had their way with it for many years. Jack
pointed out these facts to the irate farmer. But he proved recalcitrant.

“I want a hundred dollars fer thet thar roof er you don’t go on,” said
he.

“Rubbish. See here, we don’t want to do damage and not settle for it,
but that isn’t to say that we can be bled like that. We’re not so
foolish. I’ll give you twenty-five dollars for that six feet or so of
roof we’ve injured.”

An obstinate look, an expression of fixed stubbornness, came over the
farmer’s face.

“I got yer here an’ yer goin’ ter pay my price. Ther justice of ther
peace here ain’t friendly to automobuls and sich-like, an’ I reckon ef
I say so he’ll give yer all a week in jail as well as a fine. How’d you
like that, hey?”

“Threats like that don’t frighten us,” said Jack stoutly, although
inwardly he began to feel somewhat worried over the prospects ahead.
If the farmer proved as pig-headed as seemed likely it might mean that
they would have to pay his outrageous price or else be sent to prison
by some cross-grained old justice of the peace.

Of course the boy felt that the farmer’s threat was more or less of a
“bluff,” but still he knew from experience the prejudice that a great
many people, especially in remote parts of the country, still felt
against automobiles and every innovation of that type.

“Don’t scare you, hey?” sneered the farmer. “Wa’al, I cal’kerlate ter
put quite a change in yer feelings afore long. Climb down out ‘er that
thar sky-buggy an’ look slippy.”

The boys held a hasty consultation. Things began to look bad.

“Maybe we’d better pay the old wooden-head his hundred and be getting
on,” said Ned. “We don’t want to be arrested or anything like that.”

“I think that’s all a bluff,” said Jack. “Still, if we humor him it may
be better than to fight him.”

“Wa’al, are yer comin’?” demanded the farmer.

“Oh, dry up,” growled out Joyce, unable to contain himself any longer.

“Dry up, hey?” snorted the farmer. “I guess you’ll do the dryin’
yerselves. I wouldn’t take no money now. It’s satisfaction I want. I’ll
hev the whole passel of yer up afore the squire in the morning.”

This certainly looked ominous. The man was clearly as stubborn as one
of his own oxen, and had made up his mind to be as ugly as he could.
Jack wished that Joyce had not made his unfortunate remark and tried to
smooth matters over. But it was no use attempting to calm the ruffled
feelings of the angry agriculturist.

“Climb out of thar now and be right smart about it,” he snorted. “I’ll
show you thet you can’t sass Si Turpin and not suffer for it.”

“But, see here----” began Jack.

“It ain’t no use argyfyin’, young feller. The whole passel of yer goes
over to Mill Creek in ther mornin’ I reckin the squire ’ull give you a
lesson you won’t fergit.”

“Can’t you be reasonable?” struck in Tom. “We’re on our way to
Portstown. It’s important that we hurry up. We’ve got to be there at a
certain time.”

“I don’t give a hoop in Hannibal what ye’ve got ter do!” snorted the
farmer. “You’ve got to go afore the squire fust. Reckon he’ll soak
yer good. He gave a party of automobubblists a good dose last week. I
reckon he’ll be all cocked and primed fer you sky-buggy fellers.”

“Well, I guess it’s a case of pile out,” said Jack, with a rueful grin.
“This old fellow is as obstinate as a mule. We can only hope to make a
good impression on this squire, whoever he is.”

“To judge from his description,” said Tom, “he must be a nice,
whole-souled old party.”

“No palaverin’, now. Git right out. I’ll fix you up with quarters in
the barn where you won’t git out, and give yer the rogues’ march in the
morning.”

There was no help for it. One by one they clambered out, while the
hired men stood by with broad grins. They were delivered over to these
representatives of the enemy while Farmer Turpin marched grimly behind
with his gun.

“Take ’em to the red barn, Reuben,” he ordered, and the boys were
presently marched into a large barn partially filled with hay.

“Now I guess ye’ll stay put for a while,” remarked the farmer, with
grim humor, as he prepared to close the door.

“You old clod-hopper, for two cents I’d bust that hook nose of yours
in,” roared out Joyce angrily.

“That’ll be used agin’ yer at yer trial!” declared the farmer
malevolently. “Yes, sir, that’ll be used agin’ yer. Threats of
violence, hey? Oh, the squire will fix you fellers good and plenty.”

The doors were banged to and padlocked on the outside. For some time
they could hear the farmer pacing up and down as if waiting to see
if they would not make some further complaint. But they all remained
silent. They were determined not to give him the satisfaction of
thinking that he had worried them. Heiny Dill even began to sing to
himself.

By and by the steady pacing of the farmer’s feet outside died away.

“I guess he’s gone to eat supper,” said Tom. “My! how hungry I am.”

This reminded all the others of their appetites, too.

“Maybe he’ll send us something to eat,” suggested Ned hopefully.

But his optimism was not to be rewarded. It grew dark and the captives
in the barn sat supperless and disconsolate. They did not face a
pleasant prospect, supposing the squire to be all that he had been
represented by the malevolent old farmer.

How long they sat thus they did not know, but on Jack’s suggestion they
were about to find themselves beds in the hay when there came a tapping
at the barn door.

“Supper!” cried Tom, but it wasn’t, it was the man called Reuben, or
Reuben Rugg, as he announced himself.

“What do you want?” asked Jack.

“Be you fellers goin’ ter Portstown?”

“We were.”

“Well, if a feller let you fellers out would you give a feller a ride
to Portstown if a feller wanted ter git thar’?”

“We sure would, Reuben. Who wants to go to Portstown?”

“I’m ther feller that would like ter go with you fellers. I don’t want
ter work fer this feller any longer an’ if I got to Portstown I’ve
got a feller thar’ thet’s a kind uv er brother-in-law ter me. So if
you fellers want ter git out, this feller ’ull steal the key when old
Turpin’s asleep and turn you loose.”

“Good for you, Reuben. How long will it be before old Turpin, as you
call him, goes to bed?”

“Jes’ as soon as he gets through writing out what he calls a commitment
agin’ you fellers. I reckon it ‘ud go hard with you if you was ter be
taken afore the squire. He’s a larruper, the squire is. He give me a
month once fer takin’ too much red-eye and lickin’ ther constabule.”

“Well, you watch and wait, Reuben,” said Jack; “we’ll be all ready when
you are.”

They heard Reuben’s heavy footsteps retreating, and then followed a
period that seemed years in extent. But at its termination Reuben’s
cautious voice was heard.

“I’m a-goin’ ter open ther door now. Be you fellers ready?”

“We’ve been ready for the last ten years,” declared Tom, referring to
the length of time it appeared that Reuben had been gone.

The lock clicked and the doors swung open. One by one they cautiously
filed out and tip-toed across the yard to the place where the Electric
Monarch lay bulked in dark shadow. Luckily, it was moonlight, and
the craft lay in a sixty-acre field so that there was plenty of
opportunity to get a good start.

“Old Turpin didn’t monkey at all with the machine, did he, Reuben?”
asked Jack, as they crept along. He was not quite sure how far the
farmer’s malevolence might have led him.

Reuben gave a suppressed chuckle.

“Turpin touch it? Not him. He wanted to, but the old woman told him
thet ef he did as like as not he’d get electric--something or other.”

“Electrocuted?”

“Likely. Say, be you really going ter Portstown?”

“Certainly. You’re not scared, are you?” said Jack with an inward smile.

“Naw, but I got a funny kind ‘er prickly feelin’ down my back like what
I git when straw gits down my neck in threshing time,” admitted Reuben
with a nervous giggle.




CHAPTER XXVII.

A DASH FOR LIBERTY.


As silently as possible the escaped captives made for the Electric
Monarch. They had almost gained the side of the craft when an
unexpected obstacle barred their further progress. The interruption was
in the form of a big white bulldog.

“Gosh all hemlock!” gasped Reuben, “I plumb forgot about old Lion.”

“Is he mean?” asked Tom.

“Mean, wa’al he’s a sight meaner than old Turpin hisself, and thet’s
a-goin’ some.”

As if to show that his character had been described correctly, Lion
gave a low growl and then, without any further warning, sprang straight
at Jack. The boy jerked up his foot and caught the animal under the
chin. With a yapping bark it tumbled back, but collected itself in
an instant for another spring.

[Illustration: “Maw! Maw!” They heard him yell at the top of his lungs,
“the boys is got out”.--_Page 249_]

At the same instant the boys heard a window go up in the farmhouse.

“Wow!” exclaimed Tom, “about this time watch out for trouble.”

“Lion! Lion!” came a voice which they recognized as Turpin’s.

The dog gave a yapping bark. Simultaneously old Turpin must have
seen, by the moonlight, that the barn door in which the boys had been
confined was open.

“Maw! Maw!” they heard him yell at the top of his lungs, “the boys is
got out, gimme my gun!”

Lion at the same instant decided to make another attack, but in the
brief pause while he was listening to his master’s voice Tom had taken
time by the forelock and picked up a big rock. As Lion made another
spring Tom flung the rock.

There was a howl of dismay from Lion, who rushed toward the house.
Shouts and cries filled the air.

“Maw! the young varmints hev killed Lion!”

“Paw, take arter ’em. Hev the law on ’em.”

Then came another feminine voice.

“Look out, paw, they’re des’prit characters. They might kill you.”

“That’s the old man’s darter. Teaches school,” said Reuben laconically,
“we’d best be lighting out o’ here.”

They scrambled on board in less time than it takes to tell it. Jack
jumped for the controls and turned full power into the motor. There was
a yell of dismay from Reuben as the Electric Monarch leaped forward
like a horse under the lash. The amazed farm hand would have rolled
overboard had it not been for Tom, who grabbed him by the collar as he
lost his balance and fell sprawling on the bridge.

“Hey! Whoa thar’! Come back, you young varmints!”

The voice of Farmer Turpin came shrilly out of the night. Then behind
them came a streak of flame and the roar of an explosion. Looking
backward they could see the figure of the farmer sprawling on his back,
kicking and yelling frantically.

“Gosh ter mighty,” exclaimed Reuben, who was by this time on his feet,
“the old man fired both barrels of his scatter gun ter oncet.”

“Up we go!” cried Jack, and almost simultaneously, with his
exclamation, the Electric Monarch shot up toward the star-sprinkled sky
at an angle that almost sent Reuben into hysterics.

“Hey, stop this flying threshing machine,” he yelled, “lemme out!
Lemme----”

Tom placed a hand over the frightened farm hand’s mouth.

“You want to get to Portstown, don’t you?”

“Yer--yer--yes, sir.

“Well, you’re going there by the air-line express. Now be quiet. Heiny,
for goodness sake, cook us up some supper, and look lively about
it,--we’re almost famished.”

       *       *       *       *       *

The next morning will be one long remembered in Portstown. Early rising
citizens saw, swooping down from the skies, a vast aerial craft manned
by a crew of youths anxiously looking over the side to descry the best
landing place. They had arrived above the town shortly before daylight
but Jack had decided to cruise about till the light grew stronger, not
wishing to risk a landing in the dark. He adopted, in fact, the same
tactics that the captain of a vessel about to enter a strange port
would employ.

By the time the Electric Monarch swooped down into the twenty-acre park
in which the fair was to be held, there was a crowd of several hundred
people in the streets clamoring about the entrance to the fenced
grounds. The Electric Monarch was actually a fact, a circumstance
which was astonishing to a good many of the Portstown folks who had
thought that Captain Sprowl’s flowery advertisement was a good deal in
the nature of an exaggeration. But now they had seen, with their own
eyes, the most wonderful craft of its kind in existence, and the whole
town was wild with excitement and curiosity.

Early as the hour was, Captain Sprowl, who had been on the lookout for
the boys, soon came dashing into the grounds in a runabout automobile.
He extended them a hearty welcome and showed them where they would be
quartered during the carnival, that is, if they wished to camp on the
grounds. The boys unanimously voted in favor of the camping proposal.
They decided that it would be much more fun than stopping at a hotel.

They accompanied the captain to the hotel for breakfast, however,
a big crowd following them through the streets, much to the boys’
embarrassment. The captain, however, gloried in the notoriety.

“It shows what good advertising will do,” he said, glowing with pride,
as he escorted his young charges through the streets. Reuben did not
accompany them. He had gone out to find his brother-in-law. In the
meantime the captain, at the boys’ solicitation, had promised to get
him a job on the fair grounds if he did not find employment at anything
else, an offer which Reuben subsequently accepted.

Breakfast was a merry meal, and the boys had much to tell of their
experiences on the trip. After they had finished, they returned to
the fair grounds and were shown round by the captain. Several of the
aviators who were to take part in the carnival had already arrived and
erected their tents with gay festoons of bunting floating over them.

The boys were much disappointed, however, to learn that an air craft
they had been most anxious to see was not yet on the grounds. This was
the celebrated Sky Eagle, a big dirigible, equipped with wireless and
one of the first aërial craft to be so fitted. The captain told them
that the dirigible was on the way, however, and was expected ere long
on the grounds.

“Have you been notified by them, then?” asked Jack, rather puzzled as
to how the captain could have such information.

“Yes, they sent us a message by wireless not long since that they
expected to arrive to-day.”

“Then there is a wireless plant in the town?” asked Tom, somewhat
surprised.

“There’s one right on the grounds,” rejoined the captain, “it’s one of
the exhibits. See the aërials over yonder?”

Sure enough, in one corner of the grounds the spider-like strands of
a vertical aërial mast could be seen leading into a hut about which a
small crowd was clustered. The captain explained that the operator of
the plant was even then trying to locate the Sky Eagle. He had hardly
finished explaining this when a boy came rushing out of the wireless
hut in hot haste.

“There’s a messenger now. Maybe he’s looking for me!” cried the
captain. “Hey, boy!”

The boy turned and came running toward them.

“I was just looking for you, Captain,” he said. “Hutchings, the
operator, wants to see you.”

“News from the Sky Eagle?” asked the captain.

“I don’t know, but he said it was important.”

The boys hurried after the captain to the wireless hut. Inside they
found Hutchings, the operator, greatly excited.

“Bad news for you, Captain,” he said, holding out a yellow sheet of
paper, “a message from the Sky Eagle. She is disabled and drifting out
to sea.”

“By the trident of Neptune!” exclaimed the captain, scanning the
message, “this is bad.”

He read the message aloud:

 “On Board Sky Eagle.--We are disabled. Drifting out to sea off
 Scatiute. Send help.--Jennings, operator.”




CHAPTER XXVIII.

A DIRIGIBLE IN DANGER.


“Where is Scatiute?” asked Jack.

“About twenty miles south of here,” responded the captain. Then turning
to the operator he asked, “Have you tried to get in communication with
the Sky Eagle again?”

“Yes, sir, but with no success. Looks as if her wireless had gone out
of business. That message came in more than an hour ago. We’ve been
looking all over for you.”

“Great guns, boys, this is serious!” exclaimed the captain in an
agitated voice. “Who knows what may have happened to those poor
fellows! I must try to get hold of them, somehow. But just how I don’t
know.”

“There’s Alvin’s dirigible on the grounds,” suggested the operator.
“Maybe he’d go.”

“I’ll try him,” declared the captain. “It’s in the cause of common
humanity. I should think he’d go.”

But Lester Alvin, the owner of the Cloud Scooter, declared he had not
enough gasolene to make the trip. Two other dirigible operators were
appealed to, but both of them had excuses of one sort or another to
offer. The captain hastened back to the wireless hut where he had left
the boys.

“Any news yet?” he asked anxiously of Hutchings the operator.

Hutchings shook his head.

“I can’t get in touch with them at all,” he said. “I can’t even raise a
station that’s seen them passing over.”

The captain passed a bewildered hand across his forehead.

“What under the heavens are we to do?” he said. “I’ve appealed to
those dirigible fellows in vain. They’ve all got one excuse or another
to offer. I guess, though, the main trouble with them is ‘cold feet’ to
put it into plain English.”

“And in the meantime those poor fellows on the Sky Eagle may be
drifting helplessly over the ocean,” said Jack.

“Yes, and the worst of it is that their wireless appears to be out of
order. If that was working they could summon help from some ship. But
as it is----”

The captain broke off despairingly. He gazed up at the sky as if
seeking inspiration there and then down at the ground. But he remained
as perplexed as before.

In the meantime Jack and his companions had been holding an eager
consultation. As the captain turned to Hutchings for the twentieth
time with a demand to know if he had heard anything yet, Jack stepped
forward.

“Captain,” he said, “I guess that we can help you out.”

“What do you mean, boy?”

“That we will go out on a hunt for the Sky Eagle.”

The captain looked dumfounded. Then he gave a vigorous shake of the
head.

“No, my boy, I couldn’t allow that.”

“Why not? We have----”

“I wouldn’t be responsible for sending you boys on such a voyage.”

“There would be no real danger. We have a capable ship. We know how to
handle her. She is as good on the water as on land.”

“I know all that, Jack, but what would your father say?”

“That it is our duty to go to the aid of those poor fellows on the Sky
Eagle.”

The captain scratched his head in bewilderment.

“I don’t know what to say,” he said hesitatingly, at length.

Just then Hutchings interrupted.

“Hold on, here’s a message coming now,” he said.

“Ah! That’s the Sky Eagle,” said the captain. “We worried ourselves
unnecessarily, after all.”

But it was not the Sky Eagle that was wirelessing. The captain’s
rejoicing had been premature. Hutchings held up his hand to enjoin
silence.

Then as the dots and dashes came out of space into the watch-case
receivers at his ears he read off the message as it came.

 “Scatiute Wireless Station.--Big dirigible seen drifting east. Making
 signals of distress. Do you know anything about her?”

“Great guns!” puffed the captain. “Just as I thought, she’s drifting
out to sea sure enough. Raise ’em at Scatiute, Hutchings. Ask ’em what
appears to be the matter with her.”

Hutchings applied himself to his key and in a few minutes he had this
answer.

“Impossible to tell what is trouble. Appears to be in gas bag but not
sure. Should send help, if possible.”

“That settles it!” cried Jack, “we’ll go after her.”

“I ought to say no, but somehow, all I can say is ‘Go ahead, my boys,
and good luck’!” cried the captain, clasping the boy’s hand.

No time was to be lost and the boys hastened from the wireless office
to where the Electric Monarch stood surrounded by an admiring crowd.
There was great excitement as the boys were seen climbing on board.
People came running from all parts of the grounds for, early as
the hour was, there was still quite a small crowd scattered about
inspecting the various air craft.

“What is it?” “Are they going to make a flight?”

These and a hundred other questions were bandied about from mouth to
mouth. The boys worked like beavers and it was evident even to the
dullest-witted onlooker that there was something unusual in the wind.

In ten minutes everything was ready. At the last moment Jack had
requested a coil of good strong rope, which was loaned to him by one
of the dirigible men. When this had been taken on board all was ready
for the start. The boy took his place in the pilot house and the others
assumed their stations. Ned oiled up the motor and Tom saw that the
stern propeller bearings were in good working order.

“Good-bye and good luck!” hailed the captain as Jack’s hand sought the
starting switch.

At that moment, and just as the first impulses of the motor throbbed
through the frame of the Electric Monarch, there was a sudden motion in
the crowd.

“Lemme through!” bawled a voice, which Ned Nevins recognized with a
start. It was Hank Nevins, his ne’er-do-well cousin. Close at Hank’s
heels came Miles Sharkey. The two elbowed their way through the crowd,
followed by a thickset man who bore the unmistakable stamp of an
officer of the law. Miles Sharkey was waving a paper above his head.

“Hold on!” he bawled at the top of his voice, “don’t let that craft go
up!”

“Why not?” yelled Captain Sprowl, his face purple.

“This officer will explain,” cried Hank, “we got a conjunction.”

“Injunction,” he means, explained Miles, the law sharp, with a grin.
“We’ve got an injunction prohibiting those boys from handling the
Electric Monarch.”

The captain stood aghast. The boys on the Electric Monarch could
not catch just what was going on but they knew that the controversy
concerned them.

“On what grounds did you obtain this injunction?” demanded the captain,
controlling himself with difficulty.

“On the grounds that this craft belongs to Hank Nevins here. It was
built from plans left to him by his father,” cried Miles.

“How do you know they were left to him?”

“We have found a will. It was only discovered a few days ago after
that young thief on board the Monarch there had appropriated the plans
himself.”

“Is this right, officer?” demanded the confused captain in a bewildered
way. “I ain’t much of a hand at the law myself.”

“It’s right, all right,” said the officer stolidly. “They’ve got an
injunction restraining this craft from flying,--that’s the law.”

“He! he! he!” chuckled Hank. “This is the time I’ve fixed my smart
young cousin. There was a will, after all.”

Jack was becoming impatient. From the pilot house he shouted down to
the captain:

“Shall we go ahead?”

The captain was about to reply in the negative, explaining that the
law must be complied with, when Hank shoved rudely against the old
seaman, almost pushing him over.

“Lemme by,” he snarled. “I’ll attend to this!”

It was then that the vials of the captain’s wrath boiled over.

“You young limb!” he bellowed. “D’ye think I’ll sacrifice human life
for a thousand injunctions? Go ahead, boys!”

There was a roar and shout, and the Electric Monarch jumped forward.
The crowd scattered right and left. Hank and Miles leaped after the
craft. The wind from the propellers caught the former and hurled him to
the ground.

“Stop ’em!” bellowed Miles, and then he turned furiously on the
officer. “Why don’t you stop ’em, you--you muttonhead?”

“Keep a civil tongue in you, young feller,” warned the officer.
“There’s no power on earth’ll stop ’em now. That injunction will have
to wait.”

A mighty cheer from the crowd drowned Miles’s furious reply.

The Electric Monarch had taken the air in a graceful, sweeping slant.
The powerful craft was off on an errand of life or death.




CHAPTER XXIX.

A DARING RESCUE.


Entirely unconscious of the fact that they were law breakers, the boys’
hearts beat high with the love of adventure as the Electric Monarch
soared above Portstown, saluted by scores of whistles, and dashed off
south in the direction of Scatiute.

The lads had been in many surprising adventures, but they had never
encountered such a crisis as the present one. Somewhere out above the
ocean, the glimmer of which they could catch to the eastward, was
drifting a crippled dirigible with three men on board. It was their
task to find that craft and rescue the men.

The captain had confided to Jack the names of the men, and so, when Ned
put the question to him a short time after the start he was able to
inform him.

“The owner of the Sky Eagle is Mr. Holmes Morse of New York,” he said;
“with him, acting as engineer, is a man named Tyler and the operator is
named Jennings.”

“Tyler!” exclaimed Ned, as if the name struck a key in his memory. “It
is odd, but that was the name of one of my uncle’s closest friends. He
was an engineer who took up aërial work. I wonder if it could be the
same.”

“It might be. But Tyler is a very common name.”

“To be sure, but the coincidence in the names and occupations struck
me.”

“By the way, talking of that, didn’t I hear you say that in the crowd
that gathered about us before we started, you saw your rascally cousin,
Hank?”

“I did,” rejoined Ned, “but what in the world he could have been doing
here I can’t imagine. Miles Sharkey was with him, too. I’ll bet they
were up to some mischief.”

“Connected with the Electric Monarch?”

“Naturally; what else would they have been doing in Portstown.”

“But how could they have known that we were there?”

“I suppose they read that advertisement of the captain’s. He said he
had it put in every paper of any prominence.”

“I guess that’s it. It was plain enough that they were kicking up some
sort of a rumpus just as we were leaving.”

“So it looked to me. They were waving some sort of a paper.”

“Well, it isn’t our funeral. The captain gave us the word to go, and
that’s all we’ve got to do with it. I’d give a good deal to know,
though, just what they were trying to do.”

Perhaps it was just as well for Ned that he did not know. The knowledge
that the Electric Monarch was not his any longer but had been legally
left to his cousin would have made him absolutely miserable, for his
whole being was wrapped up in the craft.

“Keep a bright lookout for the lighthouse at Scatiute, Ned--we ought to
be sighting it at almost any moment now.”

“I’m watching for it,” rejoined Ned, as he went back to the motor
platform to oil the bearings.

Not more than ten minutes later Jack’s sharp eyes caught sight of a
white finger pointing upward to the sky at the extremity of a rocky
point. He guessed that this must be Scatiute. The Electric Monarch had
been skirting the coast, but as they swung by the lighthouse, Jack
headed her straight out to sea.

Then began a period of tension that was to endure for several hours.
Below them lay the glittering sea, calm and heaving gently, and
flashing in the bright sunlight. But from even that height, with the
extended horizon the elevation gave them, none of the watchers on the
Electric Monarch could detect any sign of the craft they had come in
search of.

As hour after hour went by without a sign of her, Jack’s heart began to
sink. What if they were too late--if the Sky Eagle had sunk, carrying
with her, into the depths of the sea, her unfortunate crew?

The thought was a serious one, and Jack, with a sober, thoughtful face
speeded up the Electric Monarch a trifle so as to lose no time in case
the Sky Eagle was yet above the surface of the sea.

There was but little wind, but what there was, was off shore, so that
the Sky Eagle must have drifted seaward very rapidly. Her occupants
would naturally have kept as much gas as possible in the bag in order
to keep her above the waves. In such a case the drift would have been
even more rapid than if the bag had been partially deflated.

Suddenly Joyce’s deep bass voice came booming from the forward lookout,
from which position he had been scanning the sea with binoculars.

“There’s something dead ahead of us!”

Instantly the Electric Monarch fairly vibrated excitement. Ned hastened
into the pilot house to Jack’s side. He found the young skipper with
the binoculars at his eyes.

“Can you make out what it is?” he asked.

“I’m not quite certain, yet. Whatever it is, it appears to be almost
floating on the sea. It may be a small craft, and the floating effect
may be caused by a refraction of the light or it may be----”

“The Sky Eagle!” Ned finished for him.

The next moment Joyce’s voice came thrilling through the speaking tube
from the foreward lookout.

“It’s a balloon! She’s almost in the sea!”

Simultaneously Jack had descried what the distant object was. “The
balloon” as Joyce called it was, without doubt, the Sky Eagle. But the
dirigible was perilously near to the water. In fact she appeared to be
almost touching the surface. Would they be in time?

“Hold tight!” warned Jack. “I’m going to let her out every notch.”

With a deep whirring roar the propellers began to beat the air faster.
As they churned the atmosphere at fifteen hundred revolutions a minute,
the Electric Monarch responded nobly to the powerful impulse. She was
making faster speed than ever before. The hand of the indicator crept
up and up.

“Fifty--fifty-five--sixty--sixty-five--seventy!”

“Seventy miles an hour!” gasped Ned. “Will she hold together?”

“She’s got to,” said Jack grimly, as he grasped the spokes of his wheel
more firmly. At that speed the “pull” of the rudder was terrific. He
only hoped that it would not be dragged out of its fastenings.

The Electric Monarch’s frame creaked and complained, and every brace
and wire in her structure hummed a separate song as they cut through
the air. Luckily, the wind was with them, or the craft, strong as she
was, might not have endured the cruel strain.

Every second brought them closer to the stranded and disabled
dirigible. They could see the unfortunate craft quite plainly now. She
lay with a shriveled and collapsed gas bag almost on the surface of the
waves. A jagged rent in one side showed what had brought her down into
such perilous proximity to the waves.

From time to time, so close was she to the water, a larger wave than
usual would lap up against the under part of the craft’s structure, and
drench the men marooned on board the sinking dirigible.

“Only just in time!” exclaimed Jack, as he manipulated his descending
levers, cut down the power and landed in the water not twenty yards
from the sinking Sky Eagle, with skill that resulted in hardly a
splash.




CHAPTER XXX.

A STRANGE MEETING.


The work of rescue was not easily accomplished. The boys did not dare
attach a rope to the dirigible as there was a chance that the craft
would sink at any moment. But by good luck the occupants of the craft
had on board a plank which they used in climbing in and out of the
airship’s substructure.

This came in useful now. Under Jack’s direction the plank was extended
between the two craft and one by one the luckless voyagers of the
Sky Eagle were transferred to the Electric Monarch. Great was their
wonderment at the surprising craft that had effected their rescue when
they had given up all hope.

Greater still was their gratitude to the brave lads who, at the risk of
their lives, had followed the ocean air-lanes in search of the missing
dirigible.

“We owe our lives to you, lads. I do not know how I can ever thank
you,” declared Mr. Morse, the owner of the craft.

In the meantime Henry Tyler, the machinist and engineer of the Sky
Eagle, had been staring at Ned Nevins with an amazement that was akin
to unbelief.

“Surely you are Ned, Jeptha Nevins’s nephew?” he exclaimed at length.

“Yes, and you are Henry Tyler, his dearest friend!” replied Ned, as the
two warmly shook hands.

“So it was the same Tyler after all,” smiled Jack, after they had all
been introduced.

“It certainly is a small world,” declared Mr. Morse smilingly. “So
this is the lad whose uncle designed this wonderful craft and left him
the plans of it! My boy, you have a legacy worth more than a great deal
of money.”

“_We_ think so at any rate,” said Ned, smiling at his chums.

“But where in the world have you been hiding yourself?” asked Henry
Tyler of Ned Nevins as they prepared to get under way, having
transferred a few instruments, and so forth, from the Sky Eagle.

“Why, have you been looking for me?” asked Ned in some surprise.

“Yes, for weeks. But I could obtain no clew to your whereabouts. No one
in Millville appeared to know what had become of you.”

“I have been at Nestorville with my two good friends, Jack Chadwick and
Tom Jesson. Had it not been for them the Electric Monarch would never
have been built,” said Ned, gratefully.

“I wanted to deliver to you a package left in my care by your uncle not
long before he died,” said Tyler. “He charged me to give it to you
after his death, which, it seemed, he felt was not far off. I have kept
it with me always, hoping some time to meet you and now I can at last
deliver it into the hands of its rightful owner.”

Ned, with some wonderment, took from Tyler’s hands a long yellow
envelope. He had no time to open it just then, for Jack ordered all
hands to their posts for the return voyage. They had hardly risen into
the air before the Sky Eagle was seen to settle down upon the water
with a sliding motion.

Suddenly she gave a swoop downward and the next instant the sea had
hidden her from view.

“Good-bye, old ship,” said Mr. Morse, with some emotion, “may you rest
well.”

Such was the requiem of the Sky Eagle. As to the manner in which she
had become disabled, Mr. Morse explained to the boys that the heat
of the sun had burst the bag and that following that disaster the
engines had broken down. Helpless, and with the gas leaking from the
momentarily enlarging rent, the Sky Eagle drifted rapidly out to sea.

Death stared the voyagers in the face, and they had prepared to meet
their fate as calmly as possible when, upon the horizon, they descried,
winging her way toward them, the form of the Electric Monarch. Mr.
Morse declared that words could not describe their emotions as they
sighted the outlines of the rescue ship.

The run back to the shore was made without incident. The boys flew
straight for the Fair Grounds, where they were received with what
resembled an ovation. Word of their gallant voyage of rescue had leaked
out, and the town went wild over them. They surged about the Electric
Monarch as she landed and fairly mobbed the boys. Cheers rang out
deafeningly, and the band played, at the direction of Captain Sprowl,
“Hail to the Chief,” that being the most appropriate tune the old
captain could think of.

It was in the midst of all this excitement that a stoutly built,
red-faced man came elbowing through the crowd that surrounded the boys
and made his way to where they stood in a blushing, embarrassed group.

“Which of you is Ned Nevins?” he demanded.

“Right here,” said Ned, stepping forward. “What do you want?”

“You must come with me,” was the response.

“But why? I----”

“Young man, you are under arrest,” and the red-faced man threw back his
coat and disclosed a star.

“Under arrest!” echoed Ned. “What for?”

“For disobeying an injunction of the court. Come with me.”




CHAPTER XXXI.

NED COMES INTO HIS OWN.


Ned’s dismay may be imagined. He was taken straight to the magistrate’s
courtroom where the charge against him was heard. In the meantime,
Captain Sprowl had engaged a lawyer for him, and the courtroom was
thronged when Ned’s case was called. His lawyer cautioned Ned to let
him do all the talking and the boy, feeling very nervous and ill at
ease before the battery of eyes aimed in his direction, sat silent
while the attorney explained to the court the circumstances of the case.

The magistrate heard him out and agreed with him that it seemed a
hardship that the boy should be held for disobeying an injunction in
order to save lives, but he declared that he had no powers in the
matter, as the injunction had been issued by the higher court. It
would be for that court to decide in the matter, and that therefore he
had no choice but to hold Ned in bonds of $2,000 for contempt of court.
Poor Ned turned pale when he heard this, but the lawyer hastily assured
him that it meant nothing, and was merely a formality.

“I’ve got the money right here!” bellowed Captain Sprowl from the rear
of the courtroom, flourishing a bundle of bills like a madman.

“Order in the court!” shouted the bailiffs frantically, for the
captain’s actions had caused a storm of applause.

The next day Ned’s case came up before the court which had issued the
injunction. Hank and Miles Sharkey, with greedy, triumphant faces, sat
in front seats to witness the lad’s discomfiture. Ned, seeing their
eyes fixed on him, held himself together bravely. In his eyes there was
an almost excited light. However, he appeared to be awaiting some sort
of a climax.

As for the other boys, they were openly shaking hands in the back of
the courtroom and slapping each other on the back. Captain Sprowl bore
a wide grin and Ned’s lawyer looked well pleased.

Hank and Miles noted these signs of satisfaction, and they began to
grow uneasy. This uneasiness increased to positive alarm when Ned’s
lawyer, instead of opening the proceeding in the usual way, asked to
see a copy of the will, on the strength of which the injunction had
been granted.

“Um-er-er, this is an unusual proceeding, may it please your honor,”
stammered Miles, who, not anticipating anything but plain sailing, had
decided to save a lawyer’s fee and act as his own attorney.

But the court overruled him and Miles was compelled to produce what
purported to be the last will and testament of Jeptha Nevins, deceased,
in which he left, “all papers, plans, prints and designs of my
inventions whatsoever to my beloved son, Henry Nevins.”

“If your honor pleases, may I examine that will?” asked Ned’s lawyer.

The court bowed its assent. Miles, with trembling hands, passed the
paper over to the attorney. Hank rose to his feet and tried to tip-toe
out, but he was stopped by a bailiff who told him that he had orders
not to let witnesses in the case out of the courtroom. Miserable and
dejected, Hank slipped back into his seat. His face was pasty white and
his knees shook. But he did not look a whit more wretched and abject
than Miles Sharkey, who nervously fingered his face and drummed on the
table alternately, while Ned’s lawyer scanned the will Miles had handed
him.

The lawyer finally ceased his examination of the paper, and then
clearing his throat solemnly, he said:

“Acting for the defendant in this case I pronounce this will a
forgery.” There was a buzz of excitement through the courtroom. Miles
tried to speak, but words would not come from his dry lips. Hank looked
ghastly and sank back in his seat in a wilted, crumpled heap.

“And furthermore,” relentlessly proceeded the attorney, “we have a
genuine will antedating this spurious one. If your honor will give me
permission I will produce it.”

Forthwith he placed in evidence the will of Jeptha Nevins by which he
left specifically to Ned the plans of the Electric Monarch and the
proceeds of his other inventions. (The will had been contained in the
envelope which Henry Tyler had handed to Ned on board the Electric
Monarch the day before.)

“We can prove that this is the genuine signature of Jeptha Nevins and
that the other is a base forgery,” continued the attorney, “and I
would ask your honor to make out a commitment for Miles Sharkey on the
charge of forgery in the first degree and to hold Henry Nevins on a
charge of aiding and abetting the same.”

“I didn’t aid nor abet nothin’,” shrieked out Hank despairingly, “it
was Miles done it all, your honor.”

“Shut up, you fool,” hissed Miles, but it was too late. Hank had let
the cat out of the bag with a vengeance. The commitments were made out
and in due course of time both Miles and Hank paid the penalty of their
rascality in the form of prison sentences. Hank, however, received a
light punishment, as it was clear that Miles Sharkey, who had hoped to
reap big profits from the Mellville concern, had been the ring leader
in the plot.

We have no space here to relate how the Electric Monarch acquitted
herself at the big aëro carnival. But suffice it to say that she
won every event for which she was entered, and at the conclusion of
the meet Ned was approached by the representative of an aëro-craft
manufacturing concern with an offer to build ships of the Electric
Monarch type, paying him a handsome bonus and a royalty.

On their return to High Towers, the boys found Prof. Chadwick very much
better, almost in his usual health, in fact, although Dr. Goodenough
laughingly said that he was “booked for a long vacation.”

One day, not long after their return to their home, which, by the
way, was now also Ned Nevins’, the gentleman who had tried to make
negotiations with Ned at the carnival paid a visit to High Towers to
try to close a deal with the young inventor.

Professor Chadwick and Dr. Goodenough were called into consultation,
and after a long conference, it was decided that it would be to Ned’s
advantage to accept the firm’s offer, more especially as he would,
under their terms, retain an interest in the Electric Monarch type of
hydroaeroplane.

When these arrangements had been concluded, Professor Chadwick reached
into a drawer of his desk, at which he was seated, in order to produce
blotting paper to sign the contracts. But as he opened the drawer he
suddenly paused, turned deathly pale, and pressed his hand to his
forehead.

“What is the matter, are you ill?” cried the doctor in a concerned
voice.

The boys, full of anxiety and alarm, repeated the question. But
Professor Chadwick waved them aside.

“No, not ill,” he exclaimed in a strange voice. “Wait--wait! It is
coming back to me now!”

He pressed a spring in his desk, and a secret drawer flew open. As it
did so, they all uttered a shout of astonishment.

It contained the long-missing plans!

The mystery was soon explained. The Professor’s memory had come back to
him with a rush when he opened the drawer for the blotting paper. On
the day of the trial trip of the Electric Monarch, it will be recalled,
he had been left behind. After the boys’ departure, (as it came back to
him, he had begun to feel uneasy about the plans, secure though they
seemed to be in the safe.)

He decided to find a better hiding place than the safe even, for them,
and with that object in view arose from the lounge and opened the
receptacle. Taking out the papers, he placed them in the secret drawer
of the desk. Hardly had he done so, however, when an attack of vertigo
seized him and he fell unconscious. Now that his memory had come back
suddenly, as he seated himself once more at the desk, all became clear.

And so the mystery of the vanished plans was cleared up with
satisfaction to all of them. After all, they had wrongfully suspected
Hank and his allies, and they were glad to learn that their suspicions
had been unfounded.

There is little more to tell. Heiny Dill finally evolved a burglar
trap out of his invention, but he makes more money working for the Boy
Inventors at High Towers than he does out of his numerous eccentric
contrivances. Sam Hinkley returned to Nestorville not long after his
invasion of New York, and after he had begged for forgiveness, his
father finally gave him the post of night clerk in the hotel, which he
fills admirably. Of the fate of Hank and Miles we are already informed.

And so, with Ned Nevins prosperous and happy, and the Boy Inventors
broadened and improved by their experiences with the Electric Monarch,
we will, for the present, leave them with the best of wishes for
their future undertakings. Knowing them to be always on the alert for
the latest developments in scientific progress, we are not greatly
surprised to learn that their next experimental experiences will be
described in a volume entitled, “The Boy Inventors’ Radio Telephone.”

BOY AVIATORS’ SERIES

By Captain Wilbur Lawton

Absolutely Modern Stories for Boys

  Cloth Bound       Price, 50c per volume


The Boy Aviators in Nicaragua

Or, Leagued With Insurgents

The launching of this Twentieth Century series marks the inauguration
of a new era in boys’ books--the “wonders of modern science” epoch.
Frank and Harry Chester, the Boy Aviators, are the heroes of this
exciting, red-blooded tale of adventure by air and land in the
turbulent Central American republic. The two brothers with their
$10,000 prize aeroplane, the Golden Eagle, rescue a chum from death in
the clutches of the Nicaraguans, discover a lost treasure valley of the
ancient Toltec race, and in so doing almost lose their own lives in the
Abyss of the White Serpents, and have many other exciting experiences,
including being blown far out to sea in their air-skimmer in a tropical
storm. It would be unfair to divulge the part that wireless plays in
rescuing them from their predicament. In a brand new field of fiction
for boys the Chester brothers and their aeroplane seem destined to fill
a top-notch place. These books are technically correct, wholesomely
thrilling and geared up to third speed.


The Boy Aviators on Secret Service

Or, Working With Wireless

In this live-wire narrative of peril and adventure, laid in the
Everglades of Florida, the spunky Chester Boys and their interesting
chums, including Ben Stubbs, the maroon, encounter exciting experiences
on Uncle Sam’s service in a novel field. One must read this vivid,
enthralling story of incident, hardship and pluck to get an idea of
the almost limitless possibilities of the two greatest inventions of
modern times--the aeroplane and wireless telegraphy. While gripping and
holding the reader’s breathless attention from the opening words to the
finish, this swift-moving story is at the same time instructive and
uplifting. As those readers who have already made friends with Frank
and Harry Chester and their “bunch” know, there are few difficulties,
no matter how insurmountable they may seem at first blush, that
these up-to-date gritty youths cannot overcome with flying colors. A
clean-cut, real boys’ book of high voltage.


The Boy Aviators in Africa

Or, An Aerial Ivory Trail

In this absorbing book we meet, on a Continent made famous by the
American explorer Stanley, and ex-President Roosevelt, our old friends,
the Chester Boys and their stalwart chums. In Africa--the Dark
Continent--the author follows in exciting detail his young heroes,
their voyage in the first aeroplane to fly above the mysterious forests
and unexplored ranges of the mystic land. In this book, too, for the
first time, we entertain Luther Barr, the old New York millionaire,
who proved later such an implacable enemy of the boys. The story of
his defeated schemes, of the astonishing things the boys discovered in
the Mountains of the Moon, of the pathetic fate of George Desmond, the
emulator of Stanley, the adventure of the Flying Men and the discovery
of the Arabian Ivory cache,--this is not the place to speak. It would
be spoiling the zest of an exciting tale to reveal the outcome of all
these episodes here. It may be said, however, without “giving away”
any of the thrilling chapters of this narrative, that Captain Wilbur
Lawton, the author, is in it in his best vein, and from his personal
experiences in Africa has been able to supply a striking background
for the adventures of his young heroes. As one newspaper says of this
book: “Here is adventure in good measure, pressed down and running
over.”


The Boy Aviators Treasure Quest

Or, The Golden Galleon

Everybody is a boy once more when it comes to the question of hidden
treasure. In this book. Captain Lawton has set forth a hunt for gold
that is concealed neither under the sea nor beneath the earth, but
is well hidden for all that. A garrulous old sailor, who holds the
key to the mystery of the Golden Galleon, plays a large part in the
development of the plot of this fascinating narrative of treasure
hunting in the region of the Gulf Stream and the Sargasso Sea. An
aeroplane fitted with efficient pontoons--enabling her to skim the
water successfully--has long been a dream of aviators. The Chester
Boys seem to have solved the problem. The Sargasso, that strange
drifting ocean within an ocean, holding ships of a dozen nations and
a score of ages, in its relentless grip, has been the subject of many
books of adventure and mystery, but in none has the secret of the ever
shifting mass of treacherous currents been penetrated as it has in the
BOY AVIATORS TREASURE QUEST. Luther Barr, whom it seemed the boys had
shaken off, is still on their trail, in this absorbing book and with
a dirigible balloon, essays to beat them out in their search for the
Golden Galleon. Every boy, every man--and woman and girl--who has ever
felt the stirring summons of adventure in their souls, had better get
hold of this book. Once obtained, it will be read and re-read till it
falls to rags.


The Boy Aviators in Record Flight

Or, The Rival Aeroplane

The Chester Boys in new field of endeavor--an attempt to capture a
newspaper prize for a trans-continental flight. By the time these lines
are read, exactly such an offer will have been spread broadcast by one
of the foremost newspapers of the country. In the Golden Eagle, the
boys, accompanied by a trail-blazing party in an automobile, make the
dash. But they are not alone in their aspirations. Their rivals for the
rich prize at stake try in every way that they can to circumvent the
lads and gain the valuable trophy and monetary award. In this they stop
short at nothing, and it takes all the wits and resources of the Boy
Aviators to defeat their devices. Among the adventures encountered in
their cross-country flight, the boys fall in with a band of rollicking
cow-boys--who momentarily threaten serious trouble--are attacked by
Indians, strike the most remarkable town of the desert--the “dry” town
of “Gow Wells,” encounter a sandstorm which blows them into strange
lands far to the south of their course, and meet with several amusing
mishaps beside. A thoroughly readable book. The sort to take out behind
the barn on the sunny side of the haystack, and, with a pocketful of
juicy apples and your heels kicking the air, pass happy hours with
Captain Lawton’s young heroes.


The Boy Aviators Polar Dash

Or, Facing Death in the Antarctic

If you were to hear that two boys, accompanying a South Polar
expedition in charge of the aeronautic department, were to penetrate
the Antarctic regions--hitherto only attained by a few daring
explorers--you would feel interested, wouldn’t you? Well, in Captain
Lawton’s latest book, concerning his Boy Aviators, you can not only
read absorbing adventure in the regions south of the eightieth
parallel, but absorb much useful information as well. Captain Lawton
introduces--besides the original characters of the heroes--a new
creation in the person of Professor Simeon Sandburr, a patient
seeker for polar insects. The professor’s adventures in his quest
are the cause of much merriment, and lead once or twice to serious
predicaments. In a volume so packed with incident and peril from cover
to cover--relieved with laughable mishaps to the professor--it is
difficult to single out any one feature; still, a recent reader of it
wrote the publishers an enthusiastic letter the other day, saying:
“The episodes above the Great Barrier are thrilling, the attack of
the condors in Patagonia made me hold my breath, the--but what’s the
use? The Polar Dash, to my mind, is an even more entrancing book than
Captain Lawton’s previous efforts, and that’s saying a good deal. The
aviation features and their technical correctness are by no means the
least attractive features of this up-to-date creditable volume.”

OAKDALE ACADEMY SERIES

Stories of Modern School Sports

By MORGAN SCOTT.

Cloth Bound. Illustrated. Price, 60c. per vol., postpaid


BEN STONE AT OAKDALE.

[Illustration: Book]

Under peculiarly trying circumstances Ben Stone wins his way at Oakdale
Academy, and at the same time enlists our sympathy, interest and
respect. Through the enmity of Bern Hayden, the loyalty of Roger Eliot
and the clever work of the “Sleuth,” Ben is falsely accused, championed
and vindicated.


BOYS OF OAKDALE ACADEMY.

“One thing I will claim, and that is that all Grants fight open and
square and there never was a sneak among them.” It was Rodney Grant,
of Texas, who made the claim to his friend, Ben Stone, and this story
shows how he proved the truth of this statement in the face of apparent
evidence to the contrary.


RIVAL PITCHERS OF OAKDALE.

Baseball is the main theme of this interesting narrative, and that
means not only clear and clever descriptions of thrilling games, but
an intimate acquaintance with the members of the teams who played
them. The Oakdale Boys were ambitious and loyal, and some were even
disgruntled and jealous, but earnest, persistent work won out.


OAKDALE BOYS IN CAMP.

The typical vacation is the one that means much freedom, little
restriction, and immediate contact with “all outdoors.” These
conditions prevailed in the summer camp of the Oakdale Boys and made it
a scene of lively interest.


THE GREAT OAKDALE MYSTERY.

The “Sleuth” scents a mystery! He “follows his nose.” The plot
thickens! He makes deductions. There are surprises for the reader--and
for the “Sleuth,” as well.


NEW BOYS AT OAKDALE.

A new element creeps into Oakdale with another year’s registration of
students. The old and the new standards of conduct in and out of school
meet, battle, and cause sweeping changes in the lives of several of the
boys.

By RICHARD BONNER

THE BOY INVENTORS’ WIRELESS TELEGRAPH.

[Illustration: Book]

Blest with natural curiosity,--sometimes called the instinct of
investigation,--favored with golden opportunity, and gifted with
creative ability, the Boy Inventors meet emergencies and contrive
mechanical wonders that interest and convince the reader because they
always “work” when put to the test.


THE BOY INVENTORS’ VANISHING GUN.

A thought, a belief, an experiment; discouragement, hope, effort and
final success--this is the history of many an invention; a history in
which excitement, competition, danger, despair and persistence figure.
This merely suggests the circumstances which draw the daring Boy
Inventors into strange experiences and startling adventures, and which
demonstrate the practical use of their vanishing gun.


THE BOY INVENTORS’ DIVING TORPEDO BOAT.

As in the previous stories of the Boy Inventors, new and interesting
triumphs of mechanism are produced which become immediately valuable,
and the stage for their proving and testing is again the water. On the
surface and below it, the boys have jolly, contagious fun, and the
story of their serious, purposeful inventions challenge the reader’s
deepest attention.

problem that Jack Merrill and his friends, including Coyote Pete, face
in this exciting tale.


THE BORDER BOYS ACROSS THE FRONTIER.

Read of the Haunted Mesa and its mysteries, of the Subterranean River
and its strange uses, of the value of gasolene and steam “in running
the gauntlet,” and you will feel that not even the ancient splendors of
the Old World can furnish a better setting for romantic action than the
Border of the New.


THE BORDER BOYS WITH THE MEXICAN RANGERS.

As every day is making history--faster, it is said, than ever
before--so books that keep pace with the changes are full of rapid
action and accurate facts. This book deals with lively times on the
Mexican border.


THE BORDER BOYS WITH THE TEXAS RANGERS.

The Border Boys have already had much excitement and adventure in their
lives, but all this has served to prepare them for the experiences
related in this volume. They are stronger, braver and more resourceful
than ever, and the exigencies of their life in connection with the
Texas Rangers demand all their trained ability.




BUNGALOW BOYS SERIES

Cloth. Bound. Illustrated. Price, 50c. per vol., postpaid


THE BUNGALOW BOYS.

[Illustration: Book]

How the Bungalow Boys received their title and how they retained the
right to it in spite of much opposition makes a lively narrative for
lively boys.


THE BUNGALOW BOYS MAROONED IN THE TROPICS.

A real treasure hunt of the most thrilling kind, with a sunken Spanish
galleon as its object, makes a subject of intense interest at any time,
but add to that a band of desperate men, a dark plot and a devil fish,
and you have the combination that brings strange adventures into the
lives of the Bungalow Boys.


THE BUNGALOW BOYS IN THE GREAT NORTH WEST.

The clever assistance of a young detective saves the boys from the
clutches of Chinese smugglers, of whose nefarious trade they know too
much. How the Professor’s invention relieves a critical situation is
also an exciting incident of this book.


THE BUNGALOW BOYS ON THE GREAT LAKES.

The Bungalow Boys start out for a quiet cruise on the Great Lakes and a
visit to an island. A storm and a band of wreckers interfere with the
serenity of their trip, and a submarine adds zest and adventure to it.

Especially interesting and timely is this book which introduces the

warfare and to the intimate life and surprising adventures of Uncle
Sam’s sailors.


THE DREADNOUGHT BOYS ABOARD A DESTROYER.

In this story real dangers threaten and the boys’ patriotism is tested
in a peculiar international tangle. The scene is laid on the South
American coast.


THE DREADNOUGHT BOYS ON A SUBMARINE.

To the inventive genius--trade-school boy or mechanic--this story has
special charm, perhaps, but to every reader its mystery and clever
action are fascinating.


THE DREADNOUGHT BOYS ON AERO SERVICE.

Among the volunteers accepted for Areo Service are Ned and Herc. Their
perilous adventures are not confined to the air, however, although they
make daring and notable flights in the name of the Government; nor are
they always able to fly beyond the reach of their old “enemies,” who
are also airmen.




MOTOR RANGERS SERIES

HIGH SPEED MOTOR STORIES

Cloth Bound. Illustrated. Price, 50c. per vol., postpaid


THE MOTOR RANGERS’ LOST MINE.

[Illustration: Book]

This is an absorbing story of the continuous adventures of a motor
car in the hands of Nat Trevor and his friends. It does seemingly
impossible “stunts,” and yet everything happens “in the nick of time.”


THE MOTOR RANGERS THROUGH THE SIERRAS.

Enemies in ambush, the peril of fire, and the guarding of treasure make
exciting times for the Motor Rangers--yet there is a strong flavor of
fun and freedom, with a typical Western mountaineer for spice.


 THE MOTOR RANGERS ON BLUE WATER; or, The Secret of the Derelict.

The strange adventures of the sturdy craft “Nomad” and the stranger
experiences of the Rangers themselves with Morello’s schooner and a
mysterious derelict form the basis of this well-spun yarn of the sea.


THE MOTOR RANGERS’ CLOUD CRUISER.

From the “Nomad” to the “Discoverer,” from the sea to the sky, the
scene changes in which the Motor Rangers figure. They have experiences
“that never were on land or sea,” in heat and cold and storm, over
mountain peak and lost city, with savages and reptiles; their ship of
the air is attacked by huge birds of the air; they survive explosion
and earthquake; they even live to tell the tale!

How Frank’s summer experience with his boy friends make him into a
sturdy young athlete through swimming, boating, and baseball contests,
and a tramp through the Everglades, is the subject of this splendid
story.


FRANK ARMSTRONG AT QUEENS.

We find among the jolly boys at Queen’s School, Frank, the
student-athlete, Jimmy, the baseball enthusiast, and Lewis, the
unconsciously-funny youth who furnishes comedy for every page that
bears his name. Fall and winter sports between intensely rival school
teams are expertly described.


FRANK ARMSTRONG’S SECOND TERM.

The gymnasium, the track and the field make the background for the
stirring events of this volume, in which David, Jimmy, Lewis, the “Wee
One” and the “Codfish” figure, while Frank “saves the day.”

THE GIRL AVIATORS AND THE PHANTOM AIRSHIP.

[Illustration: Book]

Roy Prescott was fortunate in having a sister so clever and devoted
to him and his interests that they could share work and play with
mutual pleasure and to mutual advantage. This proved especially true
in relation to the manufacture and manipulation of their aeroplane,
and Peggy won well deserved fame for her skill and good sense as an
aviator. There were many stumbling-blocks in their terrestrial path,
but they soared above them all to ultimate success.


THE GIRL AVIATORS ON GOLDEN WINGS.

That there is a peculiar fascination about aviation that wins and holds
girl enthusiasts as well as boys is proved by this tale. On golden
wings the girl aviators rose for many an exciting flight, and met
strange and unexpected experiences.


THE GIRL AVIATORS’ SKY CRUISE.

To most girls a coaching or yachting trip is an adventure. How much
more perilous an adventure a “sky cruise” might be is suggested by the
title and proved by the story itself.


THE GIRL AVIATORS’ MOTOR BUTTERFLY.

The delicacy of flight suggested by the word “butterfly,” the
mechanical power implied by “motor,” the ability to control assured in
the title “aviator,” all combined with the personality and enthusiasm
of girls themselves, make this story one for any girl or other reader
“to go crazy over.”




MOTOR MAIDS SERIES

Wholesome Stories of Adventure

By KATHERINE STOKES.

Cloth Bound. Illustrated. Price, 50c. per vol., postpaid


THE MOTOR MAIDS’ SCHOOL DAYS.

[Illustration: Book]

Billie Campbell was just the type of a straightforward, athletic girl
to be successful as a practical Motor Maid. She took her car, as she
did her class-mates, to her heart, and many a grand good time did they
have all together. The road over which she ran her red machine had many
an unexpected turning,--now it led her into peculiar danger; now into
contact with strange travelers; and again into experiences by fire and
water. But, best of all, “The Comet” never failed its brave girl owner.


THE MOTOR MAIDS BY PALM AND PINE.

Wherever the Motor Maids went there were lively times, for these were
companionable girls who looked upon the world as a vastly interesting
place full of unique adventures--and so, of course, they found them.


THE MOTOR MAIDS ACROSS THE CONTINENT.

It is always interesting to travel, and it is wonderfully entertaining
to see old scenes through fresh eyes. It is that privilege, therefore,
that makes it worth while to join the Motor Maids in their first
cross-country run.


THE MOTOR MAIDS BY ROSE, SHAMROCK AND HEATHER.

South and West had the Motor Maids motored, nor could their education
by travel have been more wisely begun. But now a speaking acquaintance
with their own country enriched their anticipation of an introduction
to the British Isles. How they made their polite American bow and
how they were received on the other side is a tale of interest and
inspiration.




MOTOR CYCLE SERIES

Splendid Motor Cycle Stories

By LIEUT. HOWARD PAYSON.

Author of “Boy Scout Series.”

Cloth Bound. Illustrated. Price, 50c. per vol., postpaid


THE MOTOR CYCLE CHUMS AROUND THE WORLD.

[Illustration: Book]

Could Jules Verne have dreamed of encircling the globe with a motor
cycle for emergencies he would have deemed it an achievement greater
than any he describes in his account of the amusing travels of Philias
Fogg. This, however, is the purpose successfully carried out by the
Motor Cycle Chums, and the tale of their mishaps, hindrances and
delays is one of intense interest, secret amusement, and incidental
information to the reader.


THE MOTOR CYCLE CHUMS OF THE NORTHWEST PATROL.

The Great Northwest is a section of vast possibilities and in it the
Motor Cycle Chums meet adventures even more unusual and exciting than
many of their experiences on their tour around the world. There is not
a dull page in this lively narrative of clever boys and their attendant
“Chinee.”


THE MOTOR CYCLE CHUMS IN THE GOLD FIELDS.

The gold fever which ran its rapid course through the veins of the
historic “forty-niners” recurs at certain intervals, and seizes its
victims with almost irresistible power. The search for gold is so
fascinating to the seekers that hardship, danger and failure are
obstacles that scarcely dampen their ardour. How the Motor Cycle Chums
were caught by the lure of the gold and into what difficulties and
novel experiences they were led, makes a tale of thrilling interest.




MOLLY BROWN SERIES

College Life Stories for Girls

By NELL SPEED.

Cloth Bound. Illustrated. Price, 60c. per vol., postpaid


MOLLY BROWN’S FRESHMAN DAYS.

[Illustration: Book]

Would you like to admit to your circle of friends the most charming of
college girls--the typical college girl for whom we are always looking
but not always finding; the type that contains so many delightful
characteristics, yet without unpleasant perfection in any; the natural,
unaffected, sweet-tempered girl, loved because she is lovable? Then
seek an introduction to Molly Brown. You will find the baggage-master,
the cook, the Professor of English Literature, and the College
President in the same company.


MOLLY BROWN’S SOPHOMORE DAYS.

What is more delightful than a re-union of college girls after
the summer vacation? Certainly nothing that precedes it in their
experience--at least, if all class-mates are as happy together as the
Wellington girls of this story. Among Molly’s interesting friends of
the second year is a young Japanese girl, who ingratiates her “humbly”
self into everybody’s affections speedily and permanently.


MOLLY BROWN’S JUNIOR DAYS.

Financial stumbling blocks are not the only things that hinder the
ease and increase the strength of college girls. Their troubles and
their triumphs are their own, often peculiar to their environment. How
Wellington students meet the experiences outside the class-rooms is
worth the doing, the telling and the reading.

BOY SCOUT SERIES

BY

LIEUT. HOWARD PAYSON

MODERN BOY SCOUT STORIES FOR BOYS

  Cloth Bound      Price, 50¢ per volume.


The Boy Scouts of the Eagle Patrol.

A fascinating narrative of the doings of some bright boys who become
part of the great Boy Scout movement. The first of a series dealing
with this organization, which has caught on like wild fire among
healthy boys of all ages and in all parts of the country.

While in no sense a text-book, the volume deals, amid its exciting
adventures, with the practical side of Scouting. To Rob Blake and his
companions in the Eagle Patrol, surprising, and sometimes perilous
things happen constantly. But the lads, who are, after all, typical of
most young Americans of their type, are resourceful enough to overcome
every one of their dangers and difficulties.

How they discover the whereabouts of little Joe, the “kid” of the
patrol, by means of smoke telegraphy and track his abductors to their
disgrace; how they assist the passengers of a stranded steamer and foil
a plot to harm and perhaps kill an aged sea-captain, one must read the
book to learn. A swift-moving narrative of convincing interest and
breathless incident.
