On the evening of August 7th we reached Exham Priory, where the servants assured me that nothing unusual had occurred. The cats, even old Nigger-Man, had been perfectly placid; and not a trap in the house had been sprung. We were to begin exploring on the following day, awaiting which I assigned well-appointed rooms to all my guests. I myself retired in my own tower chamber, with Nigger-Man across my feet. Sleep came quickly, but hideous dreams assailed me. There was a vision of a Roman feast like that of Trimalchio, with a horror in a covered platter. Then came that damnable, recurrent thing about the swineherd and his filthy drove in the twilit grotto. Yet when I awoke it was full daylight, with normal sounds in the house below. The rats, living or spectral, had not troubled me; and Nigger-Man was quietly asleep. On going down, I found that the same tranquillity had prevailed elsewhere; a condition which one of the assembled savants—a fellow named Thornton, devoted to the psychic—rather absurdly laid to the fact that I had now been shewn the thing which certain forces had wished to shew me.
All was now ready, and at 11 a.m. our entire group of seven men, bearing powerful electric searchlights and implements of excavation, went down to the sub-cellar and bolted the door behind us. Nigger-Man was with us, for the investigators found no occasion to despise his excitability, and were indeed anxious that he be present in case of obscure rodent manifestations. We noted the Roman inscriptions and unknown altar designs only briefly, for three of the savants had already seen them, and all knew their characteristics. Prime attention was paid to the momentous central altar, and within an hour Sir William Brinton had caused it to tilt backward, balanced by some unknown species of counterweight.
There now lay revealed such a horror as would have overwhelmed us had we not been prepared. Through a nearly square opening in the tiled floor, sprawling on a flight of stone steps so prodigiously worn that it was little more than an inclined plane at the centre, was a ghastly array of human or semi-human bones. Those which retained their collocation as skeletons shewed attitudes of panic fear, and over all were the marks of rodent gnawing. The skulls denoted nothing short of utter idiocy, cretinism, or primitive semi-apedom. Above the hellishly littered steps arched a descending passage seemingly chiselled from the solid rock, and conducting a current of air. This current was not a sudden and noxious rush as from a closed vault, but a cool breeze with something of freshness in it. We did not pause long, but shiveringly began to clear a passage down the steps. It was then that Sir William, examining the hewn walls, made the odd observation that the passage, according to the direction of the strokes, must have been chiselled
I must be very deliberate now, and choose my words.
After ploughing down a few steps amidst the gnawed bones we saw that there was light ahead; not any mystic phosphorescence, but a filtered daylight which could not come except from unknown fissures in the cliff that overlooked the waste valley. That such fissures had escaped notice from outside was hardly remarkable, for not only is the valley wholly uninhabited, but the cliff is so high and beetling that only an aëronaut could study its face in detail. A few steps more, and our breaths were literally snatched from us by what we saw; so literally that Thornton, the psychic investigator, actually fainted in the arms of the dazed man who stood behind him. Norrys, his plump face utterly white and flabby, simply cried out inarticulately; whilst I think that what I did was to gasp or hiss, and cover my eyes. The man behind me—the only one of the party older than I—croaked the hackneyed “My God!” in the most cracked voice I ever heard. Of seven cultivated men, only Sir William Brinton retained his composure; a thing more to his credit because he led the party and must have seen the sight first.
It was a twilit grotto of enormous height, stretching away farther than any eye could see; a subterraneous world of limitless mystery and horrible suggestion. There were buildings and other architectural remains—in one terrified glance I saw a weird pattern of tumuli, a savage circle of monoliths, a low-domed Roman ruin, a sprawling Saxon pile, and an early English edifice of wood—but all these were dwarfed by the ghoulish spectacle presented by the general surface of the ground. For yards about the steps extended an insane tangle of human bones, or bones at least as human as those on the steps. Like a foamy sea they stretched, some fallen apart, but others wholly or partly articulated as skeletons; these latter invariably in postures of daemoniac frenzy, either fighting off some menace or clutching other forms with cannibal intent.
