an interval, however, we approached the pit again, and found the exhalations less unbearable. Our lanterns disclosed the top of a flight of stone steps, dripping with some detestable ichor of the inner earth, and bordered by moist walls encrusted with niter. And now for the first time my memory records verbal discourse, Warren addressing me at length in his mellow tenor voice; a voice singularly unperturbed by our awesome surroundings.
"I'm sorry to have to ask you to stay on the surface," he said, "but it would be a crime to let anyone with your frail nerves go down there. You can't imagine, even from what you have read and from what I've told you, the things I shall have to see and do. It's fiendish work, Carter, and I doubt if any man without ironclad sensibilities could ever see it through and come up alive and sane. I don't wish to offend you, and Heaven knows I'd be glad enough to have you with me; but the responsibility is in a certain sense mine, and I couldn't drag a bundle of nerves like you down to probable death or madness. I tell you, you can't imagine what the thing is really like! But I promise to keep you informed over the telephone of every move—you see I've enough wire here to reach to the center of the earth and back!"
I can still hear, in memory, those coolly spoken words; and I can still remember my remonstrances. I seemed desperately anxious to accompany my friend into those sepulchral depths, yet he proved inflexibly obdurate. At one time he threatened to abandon the expedition if I remained insistent; a threat which proved effective, since he alone held the key to the thing. All this I can still remember, though I no longer know what manner of thing we sought. After he had obtained my reluctant acquiescence in his design, Warren picked up the reel of wire and adjusted the instruments. At his nod I took one of the latter and seated myself upon an aged, discolored gravestone close by the newly uncovered aperture. Then he shook my hand, shouldered the coil of wire, and disappeared within that indescribable ossuary.
For a minute I kept sight of the glow of his lantern, and heard the rustle of the wire as he laid it down after him; but the glow soon disappeared abruptly, as if a turn in the stone staircase had been encountered, and the sound died away almost as quickly. I was alone, yet bound to the unknown depths by those magic strands whose insulated surface lay green beneath the struggling beams of that waning crescent moon.
In the lone silence of that hoary and deserted city of the dead, my mind conceived the most ghastly fantasies and illusions; and the grotesque shrines and monoliths seemed to assume a hideous personality—a half-sentience. Amorphous shadows seemed to lurk in the darker recesses of the weed-choked hollow and to flit as in some blasphemous ceremonial procession past the portals of the moldering tombs in the hillside; shadows which could not have been cast by that pallid, peering crescent moon.
I constantly consulted my watch by the light of my electric lantern, and listened with feverish anxiety at the receiver of the telephone; but for more than a quarter of an hour heard nothing. Then a faint clicking came from the instrument, and I called down to my friend in a tense voice. Apprehensive as I was, I was nevertheless unprepared for the words which came up from that uncanny vault in accents more alarmed and quivering than any I had heard before from Harley Warren. He who had so calmly left me a little while previously, now called from below in a shaky whisper more portentous than the loudest shriek:
