hen I commenced to examine the surface
of the ground, near the edge of the abyss, to see whether there were not
left other remnants of the building to which the fragment of ruin
evidently belonged. But though I scrutinized the earth with the greatest
care, I could see no signs of anything to show that there had ever been
a building erected on the spot, and I grew more puzzled than ever.

Then, I heard a cry from Tonnison; he was shouting my name, excitedly,
and without delay I hurried along the rocky promontory to the ruin. I
wondered whether he had hurt himself, and then the thought came, that
perhaps he had found something.

I reached the crumbled wall and climbed 'round. There I found Tonnison
standing within a small excavation that he had made among the _debris_:
he was brushing the dirt from something that looked like a book, much
crumpled and dilapidated; and opening his mouth, every second or two, to
bellow my name. As soon as he saw that I had come, he handed his prize
to me, telling me to put it into my satchel so as to protect it from the
damp, while he continued his explorations. This I did, first, however,
running the pages through my fingers, and noting that they were closely
filled with neat, old-fashioned writing which was quite legible, save in
one portion, where many of the pages were almost destroyed, being
muddied and crumpled, as though the book had been doubled back at that
part. This, I found out from Tonnison, was actually as he had discovered
it, and the damage was due, probably, to the fall of masonry upon the
opened part. Curiously enough, the book was fairly dry, which I
attributed to its having been so securely buried among the ruins.

Having put the volume away safely, I turned-to and gave Tonnison a hand
with his self-imposed task of excavating; yet, though we put in over an
hour's hard work, turning over the whole of the upheaped stones and
rubbish, we came upon nothing more than some fragments of broken wood,
that might have been parts of a desk or table; and so we gave up
searching, and went back along the rock, once more to the safety of
the land.

The next thing we did was to make a complete tour of the tremendous
chasm, which we were able to observe was in the form of an almost
perfect circle, save for where the ruin-crowned spur of rock jutted out,
spoiling its symmetry.

The abyss was, as Tonnison put it, like nothing so much as a gigantic
well or pit going sheer down into the
