However, this is no treatise upon Natural History. He who wishes to know more of this horrid creature may read of it in recognised works of science. For myself, to have felt once its quick, hairy legs upon my bare neck and shoulders is enough for many a day, and the thing may belong to any species and genus that it likes, so long as I never set eyes upon one again.

For I was thoroughly scared; I had become as jumpy as a bean on a hot plate. I trust that I am not by nature a coward; but the atmosphere of that ghostly, misty place, the mysterious groans that I had heard, which had seemed to come from nowhere, and the long-legged, furry spider, had all so played upon my nerves that I knew neither what I was doing nor what would happen next.

I had made, in any case, as much noise as a harlequinade. I had cried out at the top of my voice and had sent my wooden blow-pipe rattling to the ground. And then I stood motionless, breathless, waiting--as it seemed--for some new calamity.

This time it was no groan I heard, but a human voice calling, at first loudly, and then more softly, in a strange foreign tongue.

I listened, and I dared not move. The silence that followed endured for minutes, during which the seconds were punctuated by the violent beating of my heart. And, presently, I began to think. As I mastered my fears, I became capable of reasoning.

It was folly to consider ghosts. Such superstitions were well enough for untutored savages, wild men of the forests, but they would never do for Richard Treadgold, who had lived his years in Sussex--though, of a certainty, I had heard of more than one so-called haunted house between Beachy Head and Selsey Bill.

I was convinced that I had heard a human voice. I had been able even to distinguish words, howbeit in a language that I did not comprehend. And if that were so, it must follow that I was not the only human soul within that gloomy ruin.

I looked about me, and saw in the starlight my blow-pipe, lying on the floor. I picked it up, and placing a dart within the mouthpiece, began to explore the place, starting at the wide entrance and making a tour of the walls.

It was not long before I came upon a square hole in the ground, edged with shallow coping stones to keep out the water when the place was flooded by the rains. It reminded me of a hatchway on board a ship.

Below it was quite dark. I lay down upon the floor at full length with the idea of listening: for I was now sure that I was on the track of the secret of the place. But presently my eyes grew accustomed to the darkness, and I saw before me a flight of narrow steps, leading downward--as it seemed--into the very bowels of the earth.
