Reaching the place where I had shot that first creature, I stopped, and made a careful scrutiny; but could see nothing. From there, I went on to where the great copingstone had fallen. It lay on its side, apparently just as it had been left when I shot the brute that was moving it. A couple of feet to the right of the nearer end, was a great dent in the ground; showing where it had struck. The other end was still within the indentation--half in, and half out. Going nearer, I looked at the stone, more closely. What a huge piece of masonry it was! And that creature had moved it, single-handed, in its attempt to reach what lay below. I went 'round to the further end of the stone. Here, I found that it was possible to see under it, for a distance of nearly a couple of feet. Still, I could see nothing of the stricken creatures, and I felt much surprised. I had, as I have before said, guessed that the remains had been removed; yet, I could not conceive that it had been done so thoroughly as not to leave some certain sign, beneath the stone, indicative of their fate. I had seen several of the brutes struck down beneath it, with such force that they must have been literally driven into the earth; and now, not a vestige of them was to be seen--not even a bloodstain. I felt more puzzled, than ever, as I turned the matter over in my mind; but could think of no plausible explanation; and so, finally, gave it up, as one of the many things that were unexplainable. From there, I transferred my attention to the study door. I could see, now, even more plainly, the effects of the tremendous strain, to which it had been subjected; and I marveled how, even with the support afforded by the props, it had withstood the attacks, so well. There were no marks of blows--indeed, none had been given--but the door had been literally riven from its hinges, by the application of enormous, silent force. One thing that I observed affected me profoundly--the head of one of the props had been driven right through a panel. This was, of itself, sufficient to show how huge an effort the creatures had made to break down the door, and how nearly they had succeeded. Leaving, I continued my tour 'round the house, finding little else of interest; save at the back, where I came across the piece of piping I had torn from the wall, lying among the long grass underneath the broken window. Then, I returned to the house, and, having re-bolted the back door, went up to the tower. Here, I spent the afternoon, reading, and occasionally glancing down into the gardens. I had determined, if the night passed quietly, to go as far as the Pit, on the morrow. Perhaps, I should be able to learn, then, something of what had happened. The day slipped away, and the night came, and went much as the last few nights had gone.
