Very cautiously, I crept forward, and peered down; but could see nothing. Then, I crossed to the left of the passage, to see whether there might be any continuation of the path. Here, right against the wall, I found that a narrow track, some three feet wide, led onward. Carefully, I stepped on to it; but had not gone far, before I regretted venturing thereon. For, after a few paces, the already narrow way, resolved itself into a mere ledge, with, on the one side the solid, unyielding rock, towering up, in a great wall, to the unseen roof, and, on the other, that yawning chasm. I could not help reflecting how helpless I was, should I be attacked there, with no room to turn, and where even the recoil of my weapon might be sufficient to drive me headlong into the depths below. To my great relief, a little further on, the track suddenly broadened out again to its original breadth. Gradually, as I went onward, I noticed that the path trended steadily to the right, and so, after some minutes, I discovered that I was not going forward; but simply circling the huge abyss. I had, evidently, come to the end of the great passage. Five minutes later, I stood on the spot from which I had started; having been completely 'round, what I guessed now to be a vast pit, the mouth of which must be at least a hundred yards across. For some little time, I stood there, lost in perplexing thought. 'What does it all mean?' was the cry that had begun to reiterate through my brain. A sudden idea struck me, and I searched 'round for a piece of stone. Presently, I found a bit of rock, about the size of a small loaf. Sticking the candle upright in a crevice of the floor, I went back from the edge, somewhat, and, taking a short run, launched the stone forward into the chasm--my idea being to throw it far enough to keep it clear of the sides. Then, I stooped forward, and listened; but, though I kept perfectly quiet, for at least a full minute, no sound came back to me from out of the dark. I knew, then, that the depth of the hole must be immense; for the stone, had it struck anything, was large enough to have set the echoes of that weird place, whispering for an indefinite period. Even as it was, the cavern had given back the sounds of my footfalls, multitudinously. The place was awesome, and I would willingly have retraced my steps, and left the mysteries of its solitudes unsolved; only, to do so, meant admitting defeat. Then, a thought came, to try to get a view of the abyss. It occurred to me that, if I placed my candles 'round the edge of the hole, I should be able to get, at least, some dim sight of the place. I found, on counting, that I had brought fifteen candles, in the bundle--my first intention having been, as I have already said, to make a torch of the lot. These, I proceeded to place 'round the Pit mouth, with an interval of about twenty yards between each.
