From there, I found that I could see nothing. The gardens presented a dim blur of shadows--a little blacker, perhaps, where the trees stood. That was all, and I knew that it was useless to shoot down into all that darkness. The only thing to be done, was to wait for the moon to rise; then, I might be able to do a little execution. In the meantime, I sat still, and kept my ears open. The gardens were comparatively quiet now, and only an occasional grunt or squeal came up to me. I did not like this silence; it made me wonder on what devilry the creatures were bent. Twice, I left the tower, and took a walk through the house; but everything was silent. Once, I heard a noise, from the direction of the Pit, as though more earth had fallen. Following this, and lasting for some fifteen minutes, there was a commotion among the denizens of the gardens. This died away, and, after that all was again quiet. About an hour later, the moon's light showed above the distant horizon. From where I sat, I could see it over the trees; but it was not until it rose clear of them, that I could make out any of the details in the gardens below. Even then, I could see none of the brutes; until, happening to crane forward, I saw several of them lying prone, up against the wall of the house. What they were doing, I could not make out. It was, however, a chance too good to be ignored; and, taking aim, I fired at the one directly beneath. There was a shrill scream, and, as the smoke cleared away, I saw that it had turned on its back, and was writhing, feebly. Then, it was quiet. The others had disappeared. Immediately after this, I heard a loud squeal, in the direction of the Pit. It was answered, a hundred times, from every part of the garden. This gave me some notion of the number of the creatures, and I began to feel that the whole affair was becoming even more serious than I had imagined. As I sat there, silent and watchful, the thought came to me--Why was all this? What were these Things? What did it mean? Then my thoughts flew back to that vision (though, even now, I doubt whether it was a vision) of the Plain of Silence. What did that mean? I wondered--And that Thing in the arena? Ugh! Lastly, I thought of the house I had seen in that far-away place. That house, so like this in every detail of external structure, that it might have been modeled from it; or this from that. I had never thought of that--
