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 _débris_: 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 bowels of the earth. For some time longer, we continued to stare about us, and then, noticing that there was a clear space away to the north of the chasm, we bent our steps in that direction. Here, distant from the mouth of the mighty pit by some hundreds of yards, we came upon a great lake of silent water--silent, that is, save in one place where there was a continuous bubbling and gurgling. Now, being away from the noise of the spouting cataract, we were able to hear one another speak, without having to shout at the tops of our voices, and I asked Tonnison what he thought of the place--I told him that I didn't like it, and that the sooner we were out of it the better I should be pleased. He nodded in reply, and glanced at the woods behind furtively. I asked him if he had seen or heard anything. He made no answer; but stood silent, as though listening, and I kept quiet also. Suddenly, he spoke.
