The pyramidal rock upon which I saw and shot the pterodactyl was more accessible. Being something of a cragsman, I did manage to get half way to the top of that. From that height I had a better idea of the plateau upon the top of the crags. It appeared to be very large; neither to east nor to west could I see any end to the vista of green-capped cliffs. Below, it is a swampy, jungly region, full of snakes, insects, and fever. It is a natural protection to this singular country.”</p>
