Holding the light high, I passed on into the cellar, and, keeping to the right, paced slowly up, until I reached the further end. I walked quietly, and looked cautiously about, as I went. But, so far as the light showed, I saw nothing unusual. At the top, I turned to the left, still keeping to the wall, and so continued, until I had traversed the whole of the vast chamber. As I moved along, I noticed that the floor was composed of solid rock, in places covered with a damp mould, in others bare, or almost so, save for a thin coating of light-grey dust. I had halted at the doorway. Now, however, I turned, and made my way up the center of the place; passing among the pillars, and glancing to right and left, as I moved. About halfway up the cellar, I stubbed my foot against something that gave out a metallic sound. Stooping quickly, I held the candle, and saw that the object I had kicked, was a large, metal ring. Bending lower, I cleared the dust from around it, and, presently, discovered that it was attached to a ponderous trap door, black with age. Feeling excited, and wondering to where it could lead, I laid my gun on the floor, and, sticking the candle in the trigger guard, took the ring in both hands, and pulled. The trap creaked loudly--the sound echoing, vaguely, through the huge place--and opened, heavily. Propping the edge on my knee, I reached for the candle, and held it in the opening, moving it to right and left; but could see nothing. I was puzzled and surprised. There were no signs of steps, nor even the appearance of there ever having been any. Nothing; save an empty blackness. I might have been looking down into a bottomless, sideless well. Then, even as I stared, full of perplexity, I seemed to hear, far down, as though from untold depths, a faint whisper of sound. I bent my head, quickly, more into the opening, and listened, intently. It may have been fancy; but I could have sworn to hearing a soft titter, that grew into a hideous, chuckling, faint and distant. Startled, I leapt backward, letting the trap fall, with a hollow clang, that filled the place with echoes. Even then, I seemed to hear that mocking, suggestive laughter; but this, I knew, must be my imagination. The sound, I had heard, was far too slight to penetrate through the cumbrous trap. For a full minute, I stood there, quivering--glancing, nervously, behind and before; but the great cellar was silent as a grave, and, gradually, I shook off the frightened sensation. With a calmer mind, I became again curious to know into what that trap opened; but could not, then, summon sufficient courage to make a further investigation. One thing I felt, however, was that the trap ought to be secured. This, I accomplished by placing upon it several large pieces of 'dressed' stone, which I had noticed in my tour along the East wall.
