Improvement in Hulling and Cleansing Hominy.


Many of our readers well remember when "hulled corn" was a standing
winter dish. This was corn or maize the kernels of which were denuded
of their "hulls" by the chemical action of alkalies, which, however,
impaired the sweetness of the food. Hominy is corn deprived of the
hulls by mechanical means leaving the corn with all its original flavor
unimpaired. Hominy is a favorite dish throughout the country, but is not
always entirely free from particles of the outer skin of the kernels.
The mill shown in perspective in the engraving is intended to obviate
this objection.

[Illustration: DONALDSON'S PATENT HOMINY MILL.]

The corn is placed in the hopper, A, from which it is fed to the hulling
cylinder contained in the case, B. The hulling machinery is driven by
a belt on the pulley, C, the other end of the shaft of which carries
a pinion which gives motion to the gear wheel, D. This, by means of a
pinion on the shaft of the blower, E, drives the fans of the blower. On
the other, or front end of the shaft which carries the gear, D, is a
bevel gear by which another bevel gear and worm is turned. The worm
rotates the worm gear, F, in two opposite arms of which are slots that
carry pins projecting inwards, which may be moved toward or away from
the center. This gear wheel turns free on the shaft that carries the
pulley, C, and is intended for opening, by means of the pins in the
arms and levers, a cover in the bottom of the hopper and a valve in the
bottom of the hulling cylinder. Coiled or bent springs return these
levers or valves to place when the pin which moves them has passed.

A wrist-pin on the gear, D, forms a crank which is connected to a bar
at the rear end of the sieves, G, pivoted to an arm at H, by which the
sieves have a shaking or reciprocating motion as the machine operates.
The blower drives out the hulls and the motion of the sieves with their
inclined position insure access of the air to every portion of the
hominy.

It will be noticed that the connection of all the parts is absolute. The
motion of the sieves, the speed of the blower, and the action of the
inlet hopper valve and the delivery hulling valve are always exactly
proportioned to the speed of the hulling cylinder, whether fast or slow.
The upper or feed valve opens upward and has a downward projecting lip
that shuts into a recess in its seat which insures security against
leakage from the hopper to the hulling cylinder during the intervals of
its being raised; a great advantage in hominy making, as no grain ought
to get into the batch until that in the cylinder is done.

Patented Oct. 15, 1867, by John Donaldson, who may be addressed for
further information at Rockford, Ill.

Nitro-Glycerin.


Professor Doremus of this city was called as a witness at the inquest
upon the bodies of the unfortunate persons killed by the recent
explosion at Bergen, N.J. The Professor having previously analyzed some
of the explosive mixture, testified as follows:--"I have subjected it
to chemical analysis, and find it to correspond to the formula C_{6},
H_{3}, O_{3}, and NO_{5}; it is well made nitro-glycerin; the substance
freezes at about 46; it is made to decompose in a very peculiar way; on
moistening paper with it it burns with rapidity; it does not explode
when red-hot copper is placed in it; we tried it with the most intense
heat--we can produce with a galvanic battery with two hundred cells
holding a gallon and a half each; some nitro-glycerin was placed in a
cup and connected with one of the poles of the battery; through a pencil
of gas carbon the other poles of the battery were connected with the
glycerin, no explosion ensued; but when the point touched the britannia
vessel the nitro-glycerin took fire, a portion burning and the rest
scattering about; this is as severe a test as we can submit it to in the
way of heat under the pressure of the air; we therefore would conclude
that nitro-glycerin carried about exposed cannot explode, even if you
drop a coal of fire into it; if the liquid is confined, or is under
pressure, then an explosion will ensue; if paper be moistened with
it and put on an anvil and a smart blow given with a hammer, a sharp
detonation ensues; if gunpowder or the fulminates of mercury, silver or
gun-cotton be ignited in a vacuum by a galvanic battery, none of them
will explode; if any gas be introduced so as to produce a gentle
pressure during the decomposition, then a rapid evolution of gases will
result; the results of decomposition in a vacuum differ from those under
atmospheric pressure or when they are burnt in a pistol, musket,
a cannon, or in a mine; where we have little or no pressure it is
difficult to get these substances to burn rapidly; nitro-glycerin is
more difficult to explode than powder; in many respects it resembles
gun-cotton which is made in a similar way; if gun-cotton be immersed
in the proto-chloride of iron it turns into common cotton; the
same experiment was tried with nitro-glycerin by mixing it with
proto-chloride of iron, and it reverted into common glycerin; there
are four well known varieties of gun-cotton made by employing acids of
different strengths; they differ in chemical composition and properties,
as well as in their explosive qualities; the late Minister of War in
Austria in 1862 stated to me that he had ordered four hundred cannon for
gun-cotton, and six months after he stated that he had ordered all
the cannon to be changed and adapted to powder, in consequence of
spontaneous combustions; much less is known of nitro-glycerin than of
gun-cotton, and probably several varieties of this article may be formed
as of gun cotton; this would explain cases of spontaneous explosion; if
the nitro-glycerin is not carefully washed to get rid of the acid, a
gradual decomposition will ensue, producing gases, which, if the vessel
be closed, will explode; my opinion is that nitro-glycerin should be
used in the most careful hands; do not think I would put it in the hands
of a common laborer for blasting purposes; it is less dangerous in a
frozen than a liquid state; I think concussion would explode frozen
nitro-glycerin.

HISERT'S ADJUSTABLE CULTIVATOR TOOTH.


The object of the device exhibited in the engraving is to allow the
teeth of a cultivator to turn slightly and avoid obstructions, while
they will follow at all times the line of draft, so that in turning the
cultivator there is no risk of breaking the teeth or their shanks, or
of overturning the implement. The cultivator blade, A, may be of any
desired form, and it is secured to the curved shank, B, which is pivoted
by a bolt to the beam, C. On the under or lower side of the beam is an
iron plate, D, having a projecting socket, E, which is the stud or pin
on which the eye of the shank turns. A bolt passing through the socket
and beam holds the shank in place. Farmers will readily perceive the
advantages of this device. It may be applied to any or all of the
different cultivators now in use. Patented Sept 3, 1867, by B.F. Hisert
who may be addressed for rights to make or sell at Norton Hill, Green
Co., N.Y., or address G.W. King, Scoharie, N.Y.

Remedy for Cold Feet in City Cars.


"Riding down town these cold mornings in the horse cars, the unpleasant
sensation of chilled feet reminds us of the plan adopted in France and
other parts of Europe to keep the feet of car passengers warm. This is
accomplished by inserting a flattened iron tube along the bottom of the
car lengthwise in the center, between the rows of seats. This tube is
raised a little above the floor level of the car to afford a rest for
the feet, yet, not enough to make a stumbling block. When the car leaves
the depot this tube is filled with hot water from a boiler kept heated
for the purpose, and this water retains its heat and gives a pleasant
warmth to the feet of the passengers and the car generally, for about
two hours, after which the tube is refilled at a convenient station on
the road. In the case of our city cars this might easily be done, and be
a cheap and exceedingly comfortable improvement."--_Evening Post_.

It should be understood that the French cars are arranged with small
compartments like stage coaches, and the passengers sit face to face,
with the warming tube above described under their feet. One tube
for every six persons. We should be glad, indeed, to see this plan
introduced here. But it is not to be expected that our city railroad
companies will do anything for the comfort of their passsengers, while
without such trouble they continue to reap rich harvests. Very likely
the idea of loading a lot of hot water upon their cars, for passengers
to stand upon, would strike them as a good joke. Their poor, broken
down, spavined horses, could not stand any additional load.

Getting Your Money Back.


The French are a curious people and one of the novelties of Parisian
enterprises is a large warehouse, in which are sold, at retail, all
manner of goods, from a diamond necklace to a shoe brush. The purchaser,
having paid the price, receives not only the goods, but a bond for the
whole amount of his purchase money, payable, after thirty years, and
guaranteed by the Credit Foncier and other moneyed corporations. The
prices charged are said to be no greater than in any other retail shops.
This is really eating your cake in order to keep it; the more you
spend the richer you will be; indeed it sets at defiance the whole of
Franklin's code of proverbs, and proves "Poor Richard" a silly fellow.
Imagine Jones lecturing his wife on her economy, and reproaching her for
a spirit of saving, "My dear, if you had bought this camel's hair shawl
thirty years ago, it would now be a source of income to us; if you
had not been so close we should now be wealthy." Smith acquires an
independence by giving his children an expensive education, and sees in
every new dress or costly jewel which his growing daughters wear, a new
mine of wealth for himself. If he can only persuade them to spend money
enough he is sure of a support in his old age.

A GIGANTIC BRIDGE.--A suspension bridge is to be erected by M. Oudry,
engineer, over the Straits of Messina, Sicily, from Point Pezzo, on the
Calabrian Coast. It is to consist of four spans of 3,281 feet each,
elevated about 150 feet above high-water level, so that the largest
ships may pass under. The proposed Roebling bridge over the East River,
between New York and Brooklyn, is to have a single span of 1,600 feet.

THE LAST NUMBER OF VOLUME XVII.


We give in this number a full index of the volume of which this is
the last issue. No doubt this will be more satisfactory to our
readers--those at least who preserve their numbers for binding, and
probably most do--than publishing the index in a separate sheet. The
list of claims in this number will be found to be unusually full, a
gratifying evidence that dullness of business does not <DW36> the
resources nor abate the industry of our inventors. With a parting word
of good will to our present subscribers and a welcome to those who begin
with our new volume, we wish for all a HAPPY NEW YEAR.

COMMENCEMENT OF A NEW VOLUME.


With the next number the SCIENTIFIC AMERICAN enters upon its
twenty-third year. Probably no publication extent will furnish a more
complete and exhaustive exhibit of the progress of science and the arts
in this country for the past twenty-two years than a complete file of
the SCIENTIFIC AMERICAN. It is a curious and interesting pastime to
compare the condition of the mechanic arts as presented in some of our
first volumes with that shown in our more recent ones. During all this
time, nearly a quarter of a century, our journal has endeavored to
represent the actual condition of our scientific and mechanical progress
and to record the discoveries and improvements in these departments
wherever made. The result is a compendium of valuable information
unattainable through any other means.

But the SCIENTIFIC AMERICAN has aimed not only to gratify a laudable
curiosity by collecting and presenting such information, but to give
practical knowledge which could be applied to valuable uses.

We labor for the producers--the mechanics, farmers, laborers--those who
build up a country and make the wilderness to blossom like the rose. We
believe that the workers are the power, especially in this country; and
while we do not wish to detract from the value of the products of merely
intellectual speculators, we still think that the world needs specially
the laborer. We use the term "laborer" in this connection in its widest
sense, comprehending he who uses brain as well as he who employs muscle;
scientific investigation and discovery should be followed by and united
to practical application.

The improvement exhibited in our past volumes will be no less noticeable
hereafter. Keeping pace with the "march of mind" we shall endeavor
always to lead rather than to follow. The different departments of our
paper are managed by those who are practically acquainted with the
subjects they profess to elucidate. "To err is human," but we shall
spare no pains nor expense to make the SCIENTIFIC AMERICAN as reliable
in its statements as it is interesting in the variety and matter of its
subjects. There are none of our people, from the student or professional
man to the day laborer, but will find something in every number, of
present or future value to him in his business.

A CHANGE AT THE PATENT OFFICE.


T.C. Theaker has resigned as Commissioner of Patents. A number of
gentlemen are mentioned as candidates for the succession, prominent
among whom are B. T. James and Charles Mason. Mr. James has acted in the
capacity of primary Examiner in the Engineering Class for a number of
years, and has filled his position acceptably. Judge Mason held the
Commissionership from 1853 to 1857, and his whole administration was
marked with reform and ability. Judge Mason was educated at West Point,
and he is a man of sterling integrity, a sound jurist, experienced in
patent law, and a splendid executive officer. One thing may be relied
upon, if Judge Mason should receive and accept the appointment of
Commissioner, inventors will not have to complain long of delay in the
examination of their cases The Judge is as industrious by nature as he
is stern and systematic by education and he will have no drones about
him. The work of the office under his administration would be brought up
and kept up.

A good day for inventors and all persons having business with the Patent
Office will dawn when Judge Mason takes the Commissioner's chair again,
and we hope the proper influences may be brought to bear to secure his
acceptance.

OBITUARY.


Ebenezer Winship, died at his home in this city Dec. 6, 1867, at the age
of 67. A long and eminently useful although unobtrusive life entitles
his memory to respect. He commenced his career as a mechanic in
the steam engine establishment of James P. Allaire, soon after the
application of steam for the propulsion of boats and long before its
application to ships for the purposes of commerce or war. For fifty-two
years, with the exception of one or two brief intervals, he was
connected with the Allaire works in this city, and for more than forty
years he was the master mechanic and general superintendent of the
works. Probably no man now living has had a more intimate connection
with the construction of the marine steam engine in all its remarkable
changes and improvements, or been so long employed at one engine
establishment.

James P. Allaire, the founder of the Allaire Works, died May 20,1858, at
the age of 73. He was an intimate acquaintance of Fulton and from the
engine of Fulton's first boat, the _Clermont_, took drawings which he
used in the construction of his first marine engines. He built the
engines for the _Chancellor Livingston_ which ran between New York and
Albany. He built also the first marine engines ever constructed in this
country, which were put into the steamship _Savannah_, the first steamer
that crossed the Atlantic, and also those for the _Pacific_ and
_Baltic_ of the Collins line, which ships surpassed in speed any before
constructed.

Under such tutelage and with such advantages Mr. Winship rose
successively through the grades of apprentice, journeyman, boss,
and foreman, to the position of master mechanic and superintendent.
Connected intimately with the progress of marine engineering for over
half a century, he was the teacher of a large number of our engineers
who now reflect credit upon their instructor. Mr. Winship's professional
skill was unsurpassed; his ability in directing and managing others and
thorough acquaintance with the minutest details made him invaluable in
the position he so long honorably filled. His personal characteristics
were faithfulness, industry, earnestness, kindness of heart, and
unvarying punctuality and promptness. As master mechanic it was his
invariable rule to be at the works an hour before the time for beginning
labor to lay out the work for the hands, getting his breakfast in winter
by gas light and returning from dinner in time to see the condition
of the work before the men arrived. In short, he made his employers'
business his own and neglected nothing which might contribute to their
success. He was a connecting link between the present generation of
mechanics and that which saw the beginnings of that great power, steam,
which has revolutionized the world. His funeral on the 8th of December
was attended by all the employes of the Allaire Works, by many from
other mechanical establishments, and a large number of citizens.

myself been your subscriber for the past four years, and knowing as
I did the value of your paper, I felt it a duty I owed to my men to
recommend the paper to their notice, and the result is as above. I am
proud to think that I have so many in my mill who can appreciate its

The Iron-Clads at Sea.


In his last annual report to Congress, the Secretary of the Navy thus
refers to the cruise of the _Miantonomah_ to Europe and her return and
of the _Monadnock_ to San Francisco, voyages the most remarkable ever
undertaken by turreted iron-clad vessels. These vessels encountered
every variety of weather, and under all circumstances proved themselves
to be staunch, reliable sea-going ships. The monitor type of vessel
has been constructed primarily for harbor defence, and it was not
contemplated that they would do more than move from port to port on our
own coast. These voyages demonstrate their ability to go to any part of
the world, and it is believed by experienced naval officers that with
slight modifications above the water line, in no way interfering with
their efficiency in action, they will safely make the longest and most
difficult voyages without convoy.

Steam, turreted iron-clads and fifteen-inch guns have revolutionized
naval warfare, and foreign governments, becoming sensible of this great
change, are slowly but surely coming to the conclusion that turreted
vessels and heavy ordnance are essential parts of an efficient fighting
navy.

THE SCIENTIFIC AMERICAN AS A MEDIUM OF BUSINESS.


We seldom publish the favorable opinions expressed by our correspondents
when in their letters they allude to this journal. If we chose we could
fill columns with notices similar to those which follow.

R. S. Miller of Logansport, Ind., under date of Dec. 2d, says:--

I have a club of 10 or 12 engaged, and will send names and money about
the 20th inst. I have been reading the SCIENTIFIC AMERICAN for several
years and frequently I find items in it of more value than the year's
subscription. In No. 9, present volume, you illustrated a plan for
setting steam boilers. I was much pleased with it and showed it to a
friend of mine who was about re-setting a 60-horse power boiler in his
machine shop. He adopted the plan. Four week's use of the improved
furnace proves all you claimed for it. My friend will be one of your new
subscribers. I shall, in a few days, re-set my 15-horse power boiler
according to the plan. Every live mechanic should take your valuable
journal.

The Lamb Knitting Machine Manufacturing Co, Chicopee Falls, Mass.,
say:--

In payment of your bill please find inclosed draft, etc. Please insert
our advertisement every other week hereafter. We are compelled to this
being overrun with orders. Unless they hold up we shall be obliged to
withdraw it entirely. So much for the advantages of your medium for
advertising.

C.W. Le Count, Manufacturer of lathe dogs and steam engine governors,
South Norwalk, Conn., writes concerning his advertisement in these
columns:

What business I have I can trace three-quarters of it directly to your
journal.

An agent of the Hinkley Knitting Machine Co., whose invention was
illustrated in these columns some weeks ago, writes:

It is now but ten days since its publication, yet without a single
advertisement in any paper I have been obliged to engage extra
assistance to simply inclose my circulars to parties, who are writing
and even _telegraphing_ for agencies and machines, while many
have traveled long distances to personally engage agencies. The
Superintendent of the Company makes similar _complaints_.

HUNT'S IMPROVED STEAM PACKING PISTON.


Engineers are aware that there are more or less objections to the use
of the ordinary spring pistons, owing to the changing tension of the
springs, the necessity of frequent adjustment, and the impossibility of
the packing rings adapting themselves to the varying pressures of the
steam on the piston. A number of attempts have been made to produce a
self packing or steam expanding piston, which will act always with the
pressure of the steam and the velocity of the engine. The advantages
of such a piston will be readily appreciated by practical engineers,
especially drivers of locomotives, working, as they nearly all do, at a
very high pressure of steam. The general complaint against the several
packings in use on our railroads is, that they "pack too tight,"
and rapidly wear out the rings, while the only remedy has been, the
extremely uncertain one of contracting the openings by which steam is
admitted under the ring, or rings, to expand them. The obvious objection
to such an arrangement is, that it allows the steam to act on the rings
with its full force during slow motion, as when a train is starting,
while if effective under any circumstances, it will be so only at
comparatively high piston speed. The efficacy of such a remedy, if it
possesses any, is in fact inversely as the piston speed.

[Illustration: Fig.1]

Fig. 1 is a perspective of the piston itself, or the "spider," with its
follower and its rings removed, which are shown in Fig. 2. Fig. 3 is a
cross section of another form of the piston, to be presently described,
but which will serve to explain that shown in Figs. 1 and 2. Next to the
core of the spider are two narrow internal rings, A, in Figs. 1 and 3;
surrounding these two outer rings, B, the cross section of which is of
L-form, as seen in Fig. 3. The lips of these outer rings extend to the
whole thickness of the piston. The flange head of the piston, and also
the follower, are turned beveling on their edges to admit the steam
around the annular space thus formed under the rings, B. These spaces
are plainly exhibited at C, in Figs. 2 and 3. Both inner and outer rings
are adjusted to the bore of the cylinder by means of the gibs, D, and
set screws seen in Fig. 1.

[Illustration: Fig.2]

The section, Fig. 3, represents a modification intended for use in
vertical cylinders, if considered necessary. The additional center ring,
E, is intended to prevent leakage through the cut in the expanded ring
and over the face of the unexpanded one, which might occur when the
rings and cylinder should become so worn that the rings, when not
expanded, should collapse and leave the surface of the cylinder. The
rivets, F, shown by the dotted lines, are placed near the cuts in the
L-rings, and are intended to hold the outside and inside rings together
at that point, and prevent any tendency on the part of the latter
to collapse and let steam under that part of the L-rings. Probably,
however, if the packing is properly constructed and adjusted in the
first instance, these devices will be unnecessary. In horizontal
cylinders the weight of the piston, if properly supported on the set
screws and gibs, will accomplish these objects, if the cuts in the
L-rings are placed near the bottom side of the cylinder. The steam
enters the annular space between the beveled edges of the spider flange
and follower and the inner periphery of the overhanging part of the
L-rings, and acts only on that part.

Patented by Nathan Hunt, Sept. 17, 1867. For further information address
the patentee, or Sharps, Davis & Bonsall, Salem, Ohio, who will furnish
piston heads to order on receipt of size of cylinder and piston rod.

Improvement in Hand Drills.


There are frequent occasions in a machine shop where light drilling is
required on work it is inconvenient to bring to the lathe. For this the
Scotch or ratchet drill, if the job is heavy, is employed, and if
light, the breast drill. The placing and working of the former consumes
considerable time, and the labor of drilling with the breast drill is
excessive and exhausting. It is difficult also to hold the instrument so
steady as not to cramp and break the drill. The combination of the drill
with tongs and a pivoted bed piece, as seen in the engraving, obviates
these objections.

[Illustration: NEVERGOLD & STACKHOUSE'S TONGS DRILL.]

To the lower jaw, A, of a pair of tongs is pivoted a platen or bed, B,
having a hole through its center, which is continued through the jaw for
the passage of the drillings. The upper jaw is formed with a circular
flange on which is mounted the circular or disk-like base, C, of the
drill frame, D. This, with the frame, is secured on the jaw of the tongs
by means of two screw bolts--one seen in the engraving--passing through
the jaw and screwing into the base of the drill. These bolts pass
through semi-circular or segmental slots, by which the drill frame can
be swung around at different angles to the tongs, to adapt itself to the
convenience of the workman and the requirements of the work. If desired,
the crank by which the drill is driven may be used on the upright
spindle, E. It will be seen that the pivoted base or bed, B, will allow
the work to adapt itself always to the line of the drill.

In operation, the work being placed between the drill and platen, the
left hand presses the handles of the tongs together, while the right
turns the crank; the feed is thus graduated wholly by the pressure of
the hand. No further description is required for understanding the
construction or operation of this tool. Patented by F. Nevergold and
George Stackhouse, June 19, 1866. Applications for the whole right, or
for territorial rights, should be addressed to the latter at Pittsburgh,
Pa.

Improved Method of Securing Cutters on Boring Bars.


MESSRS. EDITORS:--Thinking it may be of use to some of the readers of
your invaluable paper, I have taken the liberty of sending you a sketch
of a new mode of securing the cutter in a boring bar or pin drill. Where
the cutters are secured, as usual, by a key, all mechanics know that it
is very difficult to set a cutter twice alike; and the notch, which
is filed in the cutter, to prevent it from moving endways, is a great
source of weakness, often causing the cutters to crack in hardening, as
well as after they are put to work. The inclosed sketch will explain
itself:

[Illustration]

A is a cutter, and B a collar, screwed upon the cutter bar, C. The edge
of this collar fits into a notch on either end of the cutter, as shown
at D, thus leaving the cutter as strong as possible at the center, and
giving it a solid support at the point where support is needed, and at
the same time insuring its always coming alike.

Brooklyn, N.Y.

THEODORE L. WEBSTER.

[The device seems to be eminently well calculated for the support of the
cutter on a boring bar, and is applicable, with but slight modification,
to a pin or "teat" drill. Machinists will readily perceive its operation
and excellencies.--EDS.

Tides and Their Causes.


The phenomenon of the daily tides of our seacoasts and tidal rivers is
attributed to the attraction of the moon upon the earth--that the moon
draws the earth towards it, and that in drawing the earth towards it, it
bulges up the water of the ocean on the side presented towards the moon,
and drawing the earth and water thus on that side, also draws the earth
_away_ from the water on the opposite side of it, and thus leaves the
water bulged up on _that_ side, and in doing all this the effect comes
after the cause some three hours, which is termed "the tide lagging
behind." Now if we knew, _per se_, what attraction of gravitation was,
and that it produced this anomaly of force, there would be nothing to
question in the matter. But as we only know by attraction that it means
_drawing to_, it is impossible to reconcile the theory of the tides as
they run to the attraction of the moon. If the moon is so potent in
drawing up, why does it not draw a bulge on the inland seas--our
great lakes? I will not discuss the question of the moon's Apogee and
Perigee--its different velocities in different parts[1] of its orbit, as
laid down by the law of Kepler, or whether it turns once on its axis in
a month, or not, as either theory will answer for its phases, as well
as for the face of the "Man in the Moon," but I will endeavor to give a
more rational theory for the phenomenon of the daily tides.

[Transcribers note 1: typo fixed, changed from 'pasts' to 'parts']

The earth revolves on its axis and makes a revolution every twenty-four
hours, and this moves its equatorial surface nearly a thousand miles per
hour. Now the water on its surface, covering about three-fourths of it,
and being more mobile than the solid earth, is, by centrifugal force,
made to roll around the earth, the same as the water is made to move
around the grindstone when in motion, a thing familiar to every body
that uses that instrument. In the Southern Ocean this motion of the
water is so well known to mariners who double Cape Horn in sailing from
San Francisco to New York, that they now run considerably lower down in
order to ride this tide eastward, than they did in former times. Here
then we have one fact of water tide more comprehensive, at least, than
the tractive theory of the moon. We have also the fact of two great
promontories in Capes Horn and Good Hope, where this great tidal wave
must strike against, and they produce constant oscillations of the water
to and fro, and produce gurgitation and regurgitation in all the gulfs
and rivers that line the coasts of the Northern, or more properly, the
Land Hemisphere. These gurgitations swell the water highest in the
places where the seas become the narrowest, as the more northern
latitudes. In addition to these daily oscillations of the water, there
are constant eddy currents, denominated "Gulf Streams," all agreeing in
their courses and motion to this theory of the ocean tides.

When our present received tide theory of moon attraction was first laid
down, the fact of the water of the great Southern ocean rolling round
faster than the solid parts of our planets was not known. Smith in his
Physical Geography, says, "The tidal wave flows from east to west, owing
to the earth's daily rotation in a contrary direction." Here he is
unintentionally correct, because the water striking these promontories
of the two great capes, is hurled back, and not, as he assumes, that
the great ocean wave is moving from east to west. The United States
government sailing charts lay down the fact of this great ocean wave
moving from west to east, south of the capes, and the ships coming from
the Pacific to the Atlantic ocean take advantage of this and ride the
sea at the rate of over twenty knots per hour, by following the routes
laid down in Maury's charts.

The old philosophy of the crystalline spheres was not more at variance
with the correct motion of the stars and planets, than the moon theory
of the tides. In their dilemma to account for the retrograde motions of
the planets, they denominated them wanderers, stragglers, because they
would not march with the "music of the spheres." In the moon theory of
the tides the lunar satellite is made to pull and push at one and the
same time, which is entirely at variance with the philosophy of force.

There is nothing in the heavens, nor in the earth, that proves to
us positively that the sun holds the planets, and the planets their
satellites, by attraction, as we are taught that the moon attracts the
water of our world. We see that all terrestrial bodies tend toward the
center of the earth, and we call this gravitation; but we cannot see how
a body moves around the earth without falling on it, by this law. We
say in dynamic philosophy, that bodies move in the direction of least
resistance, and _that_ we can positively understand; but what force _per
se_ is, we do not know. It is always better for us to explain phenomena
by positive known laws and motions, than by any that rest merely upon
conjecture.

The Great Hoosac Tunnel.


Messrs. Editors:--In No. 23, Vol. XVII., of your paper, is an article
upon the Hoosac Tunnel, but made up from data nearly a year old, and
consequently not correctly representing the tunnel as it is at the
present time. Your conclusions of course were based upon the same data;
but during the past year, and especially during the past five months,
much greater progress has been made than ever before upon the work, and
a knowledge of what has been done since the last report was issued will,
I think, give you a different impression of the time required for its
final completion.

Referring to the profile in that number of the SCIENTIFIC AMERICAN, the
following are the distances to the various points where the work is
being prosecuted:

  Distance from east end to central shaft    12,837.294 feet
      "      "  central shaft to west shaft   9,747.072  "
      "      "  west shaft to new shaft         265.000  "
      "      "  new shaft to well No. 4         659.150  "
      "      "  well No. 4 to pier[1]         1,522.825  "
                                             ----------
      "      "  east end to pier[1]          25,031.341  "

[Footnote 1: The instrument pier is 4 feet west of the present west end
of the tunnel.]

The following are the lengths of the headings at the various points of
the work, Dec. 2, 1867:

  Length of east end heading                  4,608.000 feet
     "   "  west shaft, east heading          1,262.000  "
     "   "   "     "    west heading            611.000  "
     "   "  west end heading                    617.000  "
                                             ----------
  Total length of headings                    7,098.000  "
  Leaving                                    17,933.341  "

or 3,396 miles of heading yet to be made, of which 1,218.975 feet are
between the west end and the west shaft, and 16,714.366 feet between the
west shaft and east end of the tunnel.

The central shaft is down 583 feet, and well No. 4 is down 150 feet.

The progress for the month of November, 1867, was as follows:

  East end heading                              126.00 feet
  West shaft, east heading                       33.00  "
   "     "    west heading                        5.00  "
  West end                                       20.00  "
                                              --------
  Total for the month of November               184.00  "

Thirty feet of brick arch were completed during the month at the west
end, making a total of 516 feet of brick arch completed to date.

The progress for the last six months has been as follows:

  East end                                      711.00 feet
  West shaft, east heading                      216.00  "
   "     "    west    "                         288.00  "
  West end                                      180.00  "
                                             ---------
  Total, from June 1, to Dec. 2               1,395.00  "
    "    for the previous six months            632.00  "
                                             ---------
    "      "     year ending Dec. 2, 1867     2,027.00  "

The new shaft has been sunk, and at its foot are the pumps which,
together with those at the west shaft, are now throwing out between 900
and 1,000 gallons of water per minute.

During the last month great quantities of water were struck at both
headings of the west shaft (70 gallons per minute at the east heading in
one day), and the work was stopped in consequence, which accounts for
the small progress at this point. A new pump of 1,000 gallons per minute
capacity will be at work, in addition to the above, in a few days, and
the work can then go forward with increased rapidity.

Well No. 4 is an artesian well, which is now being carried down as a
shaft to afford two more faces to work from. Its depth will be, when
finished, 215 feet, its dimensions 8 by 8 feet.

At the rate of progress for the past year it will require but eight
years and ten months to pierce through the mountain and at the rate for
the past six months it will require but six years and five months. But
when the central shaft and well No. 4 are sunk to grade the number of
faces to work from will be doubled, and the time of completion thereby
greatly diminished. At present drilling machines are employed only at
the east end, but in a few weeks they will be used at the west shaft,
and also at the central shaft as soon as the buildings and machinery are
again in place, and this again will hasten the completion of the work.
At the west shaft buildings are already erected for the manufacture of
nitro-glycerin, and the use of this powerful explosive will be adopted
during the present month. In fine, every means that will hasten the work
will be employed, and ere the present generation passes away, and
even within from four to seven years, trains loaded with freights and
passengers will pass and repass through the great heart of the Hoosac
Mountain as an hourly occurrence.

Horse-hair Snakes--Wonderful Transformation.


Messrs. Editors:--In No. 21, current volume, you referred H. K., of
Wis., who had described the horse-hair snake, to page 280, No. 18
current volume, for a reply, which you considered "sufficient." With
your kind permission I would like to speak a few words about the
"snakes" in question. When I resided in Pennsylvania, I, in company with
many other lads, used to tie a bundle of horse hairs into a hard knot
and then immerse them in the brook, when the water began to get warm,
and in due time we would have just as many animals, with the power of
locomotion and appearance of snakes, as there were hairs in the bundle.
I have raised them one-eighth of an inch in diameter, with perceptible
eyes and mouth on the butt end or root part of the hair. Take such a
snake and dip it in an alkaline solution, and the flesh or mucus that
formed about the hair will dissolve, and the veritable horse hair is
left. They will not generate in limestone water, only in freestone or
salt water.

Man Proposes, but God Disposes.


It may not be generally known that but for one of those accidents which
seem to be almost a direct interposition of Providence, Prof. Morse,
the originator of the magnetic telegraph, might have been now an artist
instead of the inventor of the telegraph, and that agent of civilization
be either unknown or just discovered. We publish from Tuckerman's "Book
of the Artists" just from the press of G. P. Putnam & Son, the following
reminiscence of Prof. Morse:

"A striking evidence of the waywardness of destiny is afforded by the
experience of this artist, if we pass at once from this early and
hopeful moment to a more recent incident. He then aimed at renown
through devotion to the beautiful; but it would seem as if the genius of
his country, in spite of himself, led him to this object, by the less
flowery path of utility. He desired to identify his name with art, but
it has become far more widely associated with science. A series of
bitter disappointments obliged him to "coin his mind for bread", for a
long period, of exclusive attention to portrait painting, although, at
rare intervals, he accomplished something more satisfactory. More than
thirty years since, on a voyage from Europe, in a conversation with
his fellow passengers, the theme of discourse happened to be the
electromagnet; and one gentleman present related some experiments he had
lately witnessed at Paris, which proved the almost incalculable rapidity
of movement with which electricity was disseminated. The idea suggested
itself to the active mind of the artist, that this wonderful and but
partially explored agent might be rendered subservient to that system of
intercommunication which had become so important a principle of modern
civilization. He brooded over the subject as he walked the deck, or lay
wakeful in his berth, and by the time he arrived at New York, had so
far matured his invention as to have decided upon a telegraph of
signs, which is essentially that now in use. After having sufficiently
demonstrated his discovery to the scientific, a long period of toil,
anxiety, and suspense intervened before he obtained the requisite
facilities for the establishment of the magnetic telegraph. It is now
in daily operation in the United States, and its superiority over all
similar inventions abroad was confirmed by the testimony of Arago and
the appropriation made for its erection by the French Government.

"By one of those coincidences which would be thought appropriate for
romance, but which are more common, in fact, than the unobservant are
disposed to confess, these two most brilliant events in the painter's
life--his first successful work of art and the triumph of his scientific
discovery--were brought together, as it were, in a manner singularly
fitted to impress the imagination. Six copies of his "Dying Hercules"
had been made in London, and the mold was then destroyed. Four of these
were distributed by the artist to academies, one he retained, and the
last was given to Mr. Bulfinch, the architect of the Capitol--who was
engaged at the time upon that building. After the lapse of many years,
an accident ruined Morse's own copy, and a similar fate had overtaken
the others, at least in America. After vain endeavors to regain one of
these trophies of his youthful career, he at length despaired of seeing
again what could not fail to be endeared to his memory by the most
interesting associations. One day he was superintending the preparations
for the first establishment of his telegraph in the room assigned at the
Capitol. His perseverence and self-denying labor had at length met
its just reward, and he was taking the first active step to obtain a
substantial benefit from his invention. It became necessary in locating
the wires, to descend into a vault beneath the apartment, which had not
been opened for a long period. A man preceded the artist with a lamp. As
they passed along the subterranean chamber the latter's attention
was excited by something white glimmering through the darkness. In
approaching the object, what was his surprise to find himself gazing
upon his long-lost Hercules, which he had not seen for twenty years. A
little reflection explained the apparent miracle. This was undoubtedly
the copy given to his deceased friend, the architect, and temporarily
deposited in the vault for safety, and undiscovered after his death."

Extraordinary Effects of an Earthquake--An American Man-of-War Carried
Over the Tops of Warehouses and Stranded.


[OFFICIAL REPORT.]

UNITED STATES STEAMSHIP "MONONGAHELA," ST. CROIX, Nov. 21, 1867.

Sir:--I have to state, with deep regret, that the United States
steamship _Monongahela_, under my command, is now lying on the beach in
front of the town of Frederickstadt, St. Croix, where she was thrown by
the most fearful earthquake ever known here. The shock occurred at 3
o'clock, P. M., of the 18th inst. Up to that moment the weather was
serene, and no indication of a change showed by the barometer, which
stood at 30 degrees 15 minutes. The first indication we had of the
earthquake was a violent trembling of the ship, resembling the blowing
off of steam. This lasted some 30 seconds, and immediately afterward the
water was observed to be receding rapidly from the beach. In a moment
the current was changed, and bore the ship toward the beach, carrying
out the entire cable and drawing the bolts from the kelson, without
the slightest effect in checking her terrific speed toward the beach.
Another anchor was ordered to be let go, but in a few seconds she was in
too shoal water for this to avail. When within a few yards of the beach,
the reflux of the water checked her speed for a moment, and a light
breeze from the land gave me a momentary hope that the jib and
foretopmost staysail might pay her head off shore, so that in the reflux
of the wave she might reach waters sufficiently deep to float her, and
then be brought up by the other anchor. These sails were immediately
set, and she payed off so as to bring her broadside to the beach. When
the sea returned, in the form of a wall of water 25 or 30 feet high, it
carried us over the warehouses into the first street of the town. This
wave in receding took her back toward the beach, and left her nearly
perpendicular on the edge of a coral reef, where she has now keeled over
to an angle of 15 degrees.

All this was the work of a few moments only, and soon after the waters
of the bay subsided into their naturally tranquil state, leaving us high
and dry upon the beach. During her progress toward the beach she struck
heavily two or three times; the first lurch carried the rifle gun on the
forecastle overboard. Had the ship been carried 10 or 15 feet further
out, she must inevitably have been forced over on her beam ends,
resulting, I fear, in her total destruction, and in the loss of many
lives. Providentially only four men were lost; these were in the boats
at the time the shock commenced. The boats that were down were all
swamped except my gig, which was crushed under the keel, killing my
coxswain, a most valuable man. During this terrific scene the officers
and men behaved with coolness and subordination. It affords me great
pleasure to state, that, after a careful examination of the position and
condition of the ship, I am enabled to report that she has sustained no
irreparable damage to her hull. The sternpost is bent, and some 20 feet
of her keel partially gone; propeller and shaft uninjured. The lower
pintle of the rudder is gone, but no other damage is sustained by it. No
damage is done to her hull more serious than the loss of several sheets
of copper, torn from her starboard bilge and from her keel.

She now lies on the edge of a coral reef, which forms a solid
foundation, on which ways may be laid. She can thus be launched in 10
feet of water at 100 feet from the beach. Gentlemen looking at the ship
from shore declare that the bottom of the bay was visible where there
was before, and is now, 40 fathoms of water.

To extricate the ship from her position I respectfully suggest that
Mr. I. Hanscom be sent down with suitable material for ways, ready for
laying down, and india-rubber camels to buoy her up. I think there is no
insuperable obstacle to her being put afloat, providing a gang of ten or
twelve good ship carpenters be sent down with the Naval Constructor, as
her boilers and engines appear to have sustained no injury. A valuable
ship may thus be saved to the navy, with all her stores and equipments.

The survey of another trans-continental railway route, which shall
follow mainly the 35th parallel of latitude, is nearly completed. Its
projectors claim this as the most feasible one across the continent,
and even if the northern and southern roads are constructed, this would
still be the favorite popular thoroughfare, and the easiest and cheapest
built.

The Chilian gun now being built at Pittsburgh, is 221/4 feet in length,
being two feet longer than the famous Rodman gun at Fort Hamilton,
this harbor, but of exactly the same bore, twenty inches. Its greatest
diameter is 5 feet 4 inches, its least diameter, 2 feet 9 inches. The
gun is designed for garrison or naval service.

From lack of economy, in reduction of ores, it is estimated that the
aggregate loss on the production of bullion in this country for the
present year will reach the sum of $25,000,000.

improved attachment for reapers of that class in which the rakes act as
beaters, in the place of a reel, and are made to descend occasionally to
sweep the bundle from the platform, so that the third, fourth, sixth, or
any other desired rake may sweep the platform and deliver the bundle.

SKY ROCKET.--John W. Hadfield, Newtown, N. Y.--This invention relates to
a modification of an improvement in sky rockets for which letters patent
were granted to this inventor bearing date Nov. 28, 1865. The original
improvement consisted in a novel application of wings to the body or
"carcass" of the rocket, whereby the use of the ordinary guide stick was
rendered unnecessary and the rockets rendered capable of being packed
for transportation much more compactly than when provided with sticks.
The present invention also consists in a novel manner of attaching the
wings to the body or "carcass" of the rocket, whereby the same advantage
is obtained as hitherto, at a less cost of manufacture.

TAIL PIECE FOR VIOLINS.--James Thoms, South Boston, Mass.--This
invention relates to a new and improved manner of attaching the E-string

the manner in which a stick of fire wood, or cord wood, is held fast
or secured in the saw buck for the purpose of sawing it into suitable
lengths, and it consists in arranging adjustable toothed clamps for
holding the stick, which clamps are brought in contact with it by
bearing upon a treddle with the foot.

PLATFORM SCALES.--D. Hazzard, Milton, Del.--This invention relates to a
new and improved method of constructing scales of the platform kind, and
it consists in attaching a spiral spring to a spindle, to the top end of
which spindle the platform is secured, and to the bottom end of which a
rod and index finger is attached so that when an article, to be weighed,
is placed on the platform, the weight of the article will act upon the
spring and be indicated by the finger.

Wis.--This invention consists in attaching the blade of a try square
to the stock in such a manner that it can be set and fastened at any
desired angle by operating a hook slide and set screws.

STEAM ENGINE.--J. F. Troxel, Bloomsville, Ohio.--This invention relates
to a new and improved method of constructing steam engines, whereby the
same are greatly increased in power and effectiveness, and consists in
operating a number of pistons in one cylinder.

STOVE.--T. W. Wisner, Howell, Mich.--This invention relates to a new and
improved method of constructing those stoves which are used for drying
purposes or for heating water, or steaming vegetables and for all other
purposes of a similar nature, and the invention consists in rendering
the stove portable by providing for supporting the same on truck wheels
which allows of its being transported from place to place, as may be
required.

FURNACE HOT AIR BLAST.--Richard Long, Chillicothe, Ohio.--This invention
relates to a new and improved method of constructing and arranging
the air pipes for heating the air blast for furnaces for smelting
and reducing the ores in the manufacture of iron, having particular
reference to the materials of which the air pipe is formed, the
method of its construction, and also to the materials and method of
construction of the supporting walls.

PRINTING POINTERS.--R. W. Macgowan, New York city.--This invention
relates to a new and improved application of pointers to printing
presses for registering the sheets of paper as they are fed to the
press. Hitherto these pointers have been operated automatically, from
the running parts of the press allowed to remain in an elevated or
nearly upright position, and through the sheet until the fingers or
nippers of the cylinder arrive in proper position to grasp the sheet, at
which time the pointers are drawn down and the sheet released, so that
it may be connected with the cylinder, and related with the same in
order to receive the impression. This improvement consists in applying a
spring or an equivalent weight to the pointers, the latter being pivoted
at their lower ends, or attached to axes and all constructed and
arranged in such a manner that the pointers will hold the sheets
properly in position on the feed board, and the nippers of the cylinder
allowed to draw the sheet off from the points on account of the latter
yielding or being allowed to be drawn down under the slight pull of the
sheet, the springs or weights throwing the points back to their original
position as soon as the sheet is withdrawn.

CLEANER FOR LAMP CHIMNEYS, ETC.--R. B. Musson, Champaign, Ill.--This
invention relates to an improved cleaner for lamp chimneys, bottles, and
other hollow ware.

SAWYER'S RULE.--Thomas Carter, Louisville, Ky.--This invention relates
to an improved sawyer's rule, and consists of a rule on which is a scale
showing at a glance the number of boards or planks, of any desired
thickness, which can be sawn from a log of any given diameter.

WINDOW SCREEN.--A. W. Griffith, Roxbury, Mass.--This invention relates
to an improvement in window screens, and consists in a screen wound
round a spring roller at foot of a window, and attached to the bottom of
the lower sash so that on opening the window the screen opens with it,
admitting the air but excluding insects, and on closing the sash the
screen winds up itself.

SHOVEL PLOW, CULTIVATOR, ETC.--P. Atkinson Ross, Harveys, Pa.--This
invention has for its object to improve the construction of single and
double-shovel plows, cultivators, etc., to enable them to be readily
adjusted for use upon sidehills or level ground, so that the handles may
be secured in nearly a level position, while the plow is held in the
best position for doing the work properly.

SKY ROCKETS.--John W. Hadfield, East Williamsburgh, N. Y.--This
invention consists in dispensing with the long stick or guide which is
now attached to sky rockets in order to insure a straight upward flight
of the same in the air, and using instead a plurality of short guides,
whereby several important advantages are obtained, to wit: the packing
of the rockets in a small space, so as to economise in transportation,
the forming of a stand or support for the rocket, so that no fixture of
any kind will be required when they are to be fired or "set off," and
lastly, the obtaining of an efficient guide to insure the straight
flight of the rockets upward in the air.

CATCHING THE OXYDE OF ZINC.--G. C. Hall, Brooklyn, N. Y.--This invention
relates to an improved means for catching the oxyde of zinc, as it
escapes with the fumes and gases from roasting zinc, or zinc ore.
Hitherto the oxyde of zinc has been caught and retained by forcing the
fumes and gases from the roasting ore into a large bag or receptacle
composed of cotton cloth or other porous material, which will admit
of the gases and air passing it, but not the oxyde, the latter being
retained within the bag, and, by its superior gravity, falling to the
bottom thereof and settling in teats or pendent receptacles at the
bottom of the bag, from which it is removed from time to time. This
invention has for its object the dispensing with the large bag, which
is very expensive--the gases from the ore affecting the same so that it
rots in a very short time, and soon becomes ruptured under the blows
which are given it to cause the oxyde which adheres to the sides of
the bag to drop into the teats or receptacles made to receive it. The
invention consists in having the fumes and gases from the roasting zinc
or zinc ore forced into a close building, provided with openings or
apertures, over which screens are placed, constructed in such a manner
and of such materials as to admit of the air and gases passing through
them, but not the oxyde.

FERRULE.--Archibald Shaw, Philadelphia, Pa.--This invention relates to a
new and improved ferrule for the handles of tools and other implements,
and it consists in providing the interior of the ferrule with oblique
spurs or projections, disposed or arranged in such a manner as to admit
of the ferrule being driven on the handle and at the same time prevent
it from casually slipping off therefrom. The object of the invention is
to obviate the necessity of tacks or screws being used to secure the
ferrule on the handle, as well as the pinching of the same externally to
form a burr to sink into the handle to effect the same end.

SUCTION OF VACUUM PUMP AND BLOWER.--John Doyle and Timothy A. Martin,
New York City.--This invention consists in arranging valves and air
passages with a hollow cylinder or drum having an oscillating movement,
and provided with a chamber or chambers to receive water, mercury or
other fluid, whereby an exceedingly simple and compact pump or blower is
obtained, one not liable to get out of repair or become deranged by use.

MACHINE FOR REGSTERING NUMBERS FOR ODOMETERS.--Henry F. Hart, New York
city.--This invention relates to an improved machine or apparatus
for registering numbers applicable to odometers or measurements of
quantities of all kinds, such as the numbers of barrels of flour,
bushels of grain or any other commodity that requires a tally or record
of the quantity packed, stored, weighed, or handled in any manner.

DITCHING MACHINE.--A. H. and P. S. Whitacre, Morrow, Ohio.--This
invention relates to an improvement in the construction of a machine for
cutting ditches suitable for laying tile for draining lands, or pipe of
any kind, and consists in a sled worked by tackle and supporting a frame
carrying the machinery, in such manner that the frame can be raised and
lowered to cut the ditch to any required depth.

WINDOW SHADE RACK AND PULLEY FASTENING.--Wm. H. Woods, Philadelphia,
Pa.--This invention relates to an improvement in constructing a
fastening for window shades and consists in a metal rack to be attached
vertically as usual to the side of the window frame for holding the
cord connected with the shade by means of a lever dog that works in a
longitudinal slot in the rack and is engaged and disengaged with the
teeth thereof by moving the lever in and out of the slot to be secured
in places when engaged by a swivelknob on which is a pulley that covers
the cord of the shade.

FENCE POST.--Warren H. Shay, Sylvania, Ohio.--This invention relates to
an improved method of constructing fence posts and consists in forming
them of plank uprights supported by braces and held together by cross
ties and keys.

relates to a new and improved clothes-washing machine of that class
which are provided with an oscillating rubber and a concave of rollers.

RAILROAD RAILS AND CHAIRS.--John H. Downing, Salem, Mass.--This
invention relates to an improvement in railroad rails and chairs, and
consists in forming the rails in two parts, to lie side by side, with
lap joints combined with narrow chairs, having single heads placed on
each side of the rail to clamp the two parts together at the joints, and
fasten them to the ties.

MACHINE FOR STRETCHING CLOTH.--A. C. Corpe, Stafford, Conn.--This
invention relates to a new and improved machine for stretching cloth,
with a view of tendering the same smooth and enfolding such portion of
the selvedges which may have been rolled over in the manipulations to
which it was subjected after being taken from the loom.

MACHINE FOR SHARPENING SAWS.--E. B. Rich, South Boston, Mass.--This
invention relates to a machine for the sharpening of saw blades, whether
straight or circular, and consists in the combination of a revolving or
rotating grinding wheel made of any suitable material, and a holder for
the saw blade, so arranged together that as the grinding wheel revolves
the saw will be presented to the same, or the wheel to the saw-blade,
in such a manner as to produce the desired sharpening of the teeth, in
regular order and succession.

DOOR SPRING.--Rudolph Schrader, Indianapolis, Ind.--The present
invention relates to a spring for doors, that being properly connected
with the door will operate to close, whether when opened it swings
inside or outside through the casing to the door, the spring being
especially applicable to doors hung to swing through their casing, or
inside and outside.

PORTABLE DERRICK.--D. J. McDonald, Gold Hill, Nevada.--This invention
relates to a new and improved derrick, and it consists in a novel
construction and arrangement of parts, whereby the device may be readily
drawn from place to place, the crane or derrick frame adjusted in any
desired position within the scope of its movement, friction avoided, and
the whole apparatus manipulated with the greatest facility.

J. F. McK., of Md.--"What kind of silk is used for balloons, what is the
varnish which covers them, and what amount of common illuminating gas
will support one pound weight?" Silk for large balloons is now rarely
used, stout cotton cloth being substituted. Ordinary boiled linseed oil
makes a good varnish. Any elastic varnish will do, however. The specific
gravity of ordinary illuminating gas ranges from 0.540 to 0.700, air
being 1.000. Its weight may be called one-thirty-second of a pound to
the cubic foot and atmospheric air about three-fourths of a pound.

R. B. C., of Pa., says: "Here is a proposition in geometry which I would
like to see demonstrated theoretically by one of your correspondents.
The side of a regular heptagon is equal to half the side of an
equilateral triangle inscribed in the same circle. The mechanical
construction is very simple and will be found useful. I discovered it
some years ago and am not aware of its ever having been in print."

F. H., of Mich., asks "if sal-soda will scale a boiler?" H. N. Winans,
11 Wall street, N. Y. replies that in some waters it is partially
effective but at the expense of the boiler, with a certainty of foaming
and corrosion. The most reliable and positively uninjurious remedy for
incrustations is his anti-incrustation powder--in successful use for 12
years past.

T., of R. I., speaks of the famous mechanical horse shown at the Paris
Exposition which is said to have accomplished with its rider a little
over an English mile in fifty seconds, and asks what is the motive
power. As it is said that the French Government took possession of the
machine and preserves its mechanical construction a secret, we know no
more about it than about the much vaunted Napoleon cannon.

S.S., of N. Y.--"Please give the ingredients of the composition used for
tipping matches." Different manufacturers employ different materials and
in varying proportions; the mixture of phosphorus melted and stirred up
with thin glue is sufficient, although some add a quantity of powdered
glass, niter, chlorate of potash, sulphur, etc. The phosphorus, however
is the light-producing material.

R.S.B., of N.Y., alluding to the inquiry of S.W.P., in No. 23, for a
waterproof paste. "Calico printers when they wish to leave white figures
on a dark ground use what they term a 'resist paste' to cover such
places as are designed to be unaffected by the dye. If the ingredients
of this paste were known it might be what S.W.P., desires." This "resist
paste" is 1 lb. of binacetate of copper (distilled verdigris), 3 lbs.
sulphate of copper dissolved in 1 gal. water. This solution to be
thickened with 2 lbs. gum senegal, 1 lb. British gum and 4 lbs. pipe
clay; adding afterward, 2 oz. nitrate of copper as a deliquescent.

M.A.H, of Vt.--"I have a surplus of water power and desire to know the
probable cost of the apparatus for producing the electric light, with
a view of employing my surplus power in that direction." A serviceable
magneto-electrical machine for giving light is quite expensive.

MANUFACTURING, MINING, AND RAILROAD ITEMS.


For the benefit of the Union Pacific railroad, the base of the Rocky
Mountains has been fixed at the base of the Black Hills, a distance of
6.637 miles west of Cheyenne, and, according to the railway surveys
525.078 miles from Omaha.

The Pittsburg, Fort Wayne and Chicago railway have just rebuilt in
the most permanent manner an iron bridge over the Alleghany river, to
replace the old wooden Howe truss bridge, which had become inadequate
to the increasing traffic. The new bridge opens like a fan towards the
freight yard at Pittsburg being at the narrowest part, next to the main
span 55 feet wide. The river is crossed with spans averaging 1531/2 feet
in the clear, with a bearing of five feet on each pier. The principle
of the construction is known as the lattice girder plan, with vertical
stiffening. The work was executed under the superintendence of its
designer, the engineer and architect of the company Felician Stataper.

The production of precious metals in the United States from 1849 to 1867
inclusive, has amounted in value to $1,174,000,000.

The president of one of the New Jersey railroads proposes a plan to
avoid the danger to life and limb from the series of trains that run
into and out of Jersey city. The new project is to elevate the present
tracks fifteen feet above the streets, and by safe machinery to lower at
once an entire train in the depot at the river.

A mining company at Newton, Nev., are making preparations to work their
claims by means of a steam engine which will be used to throw a stream
of water instead of the ordinary hydraulic pressure They estimate that
with a ten or twelve horse power engine, then can throw 100 inches of
water with a force equal to at least 150 feet fall. The result of this
experiment is looked upon with a good deal of interest, as there is a
vast amount of good hydraulic ground in the adjoining countries, which,
as in this case, cannot be worked by the ordinary process for want of
water fall, but which, if the expedient in this case proves successful,
will soon be worked by steam engines.

By an oversight in the article on the trans-continental railroad,
published in our last issue, the Western or California section of the
road was styled the Union Pacific, instead of the Central railroad. In
the race to reach Salt Lake the California company have 400 miles more
to build, while the Union company have only 328 miles. But the country
to be traversed by the former is comparatively level, and favorable for
winter work, while that on the other side crosses four distinct mountain
ranges, and winter storms must interrupt work for several months in the
year.

PATENT OFFICE DECISIONS ON APPEAL.

USEFUL COMPOUNDS ARE PATENTABLE--THE APPLICANT NOT REQUIRED TO PROVE THE
FUNCTION OF EACH INGREDIENT.


S.H. HODGES for the Board of Examiners-in Chief.

_Application of Rew for a Patent for Preventing and Curing Swine
Cholera_.--The applicant's specific is composed of a number of medical
articles, the nature of which is not important upon the present
occasion, and it is unnecessary to enumerate them. But it is objected
that "a medical prescription" "should contain some recognition of the
medicinal properties of the several ingredients" "and the part they
perform in the compound:" or, as it is elsewhere expressed, such a
mixture should not receive the sanction of this department "unless
perhaps a satisfactory rationale should be given for the use of each of
the ingredients in the proportions named."

If the medical faculty were always satisfied themselves as to the
operation of the various remedies they employ, there might be more
reason in the objection. But it is well known that different schools
disagree widely on this subject, and there are remedies employed with
success the effect of which the most intelligent are unable to account
for. So long as there is a single one of this character to be found, and
while the operations of the vital functions are so concealed from us
that we are unable fully to comprehend the process by which any specific
operates, so long it is impossible to prescribe as a conditon of
patentability, a full explanation of the mode in which any one acts that
is brought forward. It would be still less justifiable to require such
an explanation as would content any particular class of medical men.
Every year new therapeutics are introduced into practice, and not
unfrequently some whose beneficial results are not understood. And as
long as one such may be found, it is not just to make it a condition of
its being protected by a patent, that the discoverer should bring the
scientific world to agree with him in his theory respecting it, nor even
that he should have one.

The man who stumbles upon a new and useful article is just as much
entitled to the exclusive use of it as if he had elaborated it by the
most profound and painful study. It is true that there is danger upon
this principle of countenancing mere nostrums, and giving them undue
prestige This can only be guarded against by the exercise of great
caution and requiring convincing proof of utility. Such his been
furnished in this case, in abundance.

The application cannot be rejected except upon such grounds as would
insure the rejection of nearly all medicines whatever. Nor is the Office
responsible for the false importance which the public may attach to its
proceedings, so long is they are confined to its legitimate province.
Its duties certainly must not be neglected, and meritorious petitions
refused, in order to obviate such misapprehensions.

The decision of the Primary Examiner is reversed.
