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.

Having completed the circle, I stood in the passage, and endeavored to get an idea of how the place looked. But I discovered, immediately, that they were totally insufficient for my purpose. They did little more than make the gloom visible. One thing they did, however, and that was, they confirmed my opinion of the size of the opening; and, although they showed me nothing that I wanted to see; yet the contrast they afforded to the heavy darkness, pleased me, curiously. It was as though fifteen tiny stars shone through the subterranean night.

Then, even as I stood, Pepper gave a sudden howl, that was taken up by the echoes, and repeated with ghastly variations, dying away, slowly. With a quick movement, I held aloft the one candle that I had kept, and glanced down at the dog; at the same moment, I seemed to hear a noise, like a diabolical chuckle, rise up from the hitherto, silent depths of the Pit. I started; then, I recollected that it was, probably, the echo of Pepper's howl.

Pepper had moved away from me, up the passage, a few steps; he was nosing along the rocky floor; and I thought I heard him lapping. I went toward him, holding the candle low. As I moved, I heard my boot go sop, sop; and the light was reflected from something that glistened, and crept past my feet, swiftly toward the Pit. I bent lower, and looked; then gave vent to an expression of surprise. From somewhere, higher up the path, a stream of water was running quickly in the direction of the great opening, and growing in size every second.

Again, Pepper gave vent to that deep-drawn howl, and, running at me, seized my coat, and attempted to drag me up the path toward the entrance. With a nervous gesture, I shook him off, and crossed quickly over to the left-hand wall. If anything were coming, I was going to have the wall at my back.
