Then I came to the ceiling-high mound of debris through which I had wrenched a scanty passage. My dread at wriggling through again was infinite; for my first passage had made some noise, and I now — after seeing those possible prints — dreaded sound above all things. The case, too, doubled the problem of traversing the narrow crevice. But I clambered up the barrier as best I could, and pushed the case through the aperture ahead of me. Then, torch in mouth, I scrambled through myself — my back torn as before by stalactites. As I tried to grasp the case again, it fell some distance ahead of me down the slope of the debris, making a disturbing clatter and arousing echoes which sent me into a cold perspiration. I lunged for it at once, and regained it without further noise — but a moment afterward the slipping of blocks under my feet raised a sudden and unprecedented din.
The din was my undoing. For, falsely or not, I thought I heard it answered in a terrible way from spaces far behind me. I thought I heard a shrill, whistling sound, like nothing else on earth, and beyond any adequate verbal description. It may have been only my imagination. If so, what followed has a grim irony — since, save for the panic of this thing, the second thing might never have happened.
As it was, my frenzy was absolute and unrelieved. Taking my torch in my hand and clutching feebly at the case, I leaped and bounded wildly ahead with no idea in my brain beyond a mad desire to race out of these nightmare ruins to the waking world of desert and moonlight which lay so far above. I hardly knew it when I reached the mountain of debris which towered into the vast blackness beyond the caved-in roof, and bruised and cut myself repeatedly in scrambling up its steep slope of jagged blocks and fragments. Then came the great disaster. Just as I blindly crossed the summit, unprepared for the sudden dip ahead, my feet slipped utterly and I found myself involved in a mangling avalanche of sliding masonry whose cannon-loud uproar split the black cavern air in a deafening series of earth-shaking reverberations.
I have no recollection of emerging from this chaos, but a momentary fragment of consciousness shews me as plunging and tripping and scrambling along the corridor amidst the clangour — case and torch still with me. Then, just as I approached that primal basalt crypt I had so dreaded, utter madness came. For as the echoes of the avalanche died down, there became audible a repetition of that frightful, alien whistling I thought I had heard before. This time there was no doubt about it — and what was worse, it came from a point not behind but ahead of me.
Probably I shrieked aloud then. I have a dim picture of myself as flying through the hellish basalt vault of the Elder Things, and hearing that damnable alien sound piping up from the open, unguarded door of limitless nether blacknesses. There was a wind, too — not merely a cool, damp draught, but a violent, purposeful blast belching savagely and frigidly from that abominable gulf whence the obscene whistling came.
There are memories of leaping and lurching over obstacles of every sort, with that torrent of wind and shrieking sound growing moment by moment, and seeming to curl and twist purposefully around me as it struck out wickedly from the spaces behind and beneath. Though in my rear, that wind had the odd effect of hindering instead of aiding my progress; as if it acted like a noose or lasso thrown around me. Heedless of the noise I made, I clattered over a great barrier of blocks and was again in the structure that led to the surface. I recall glimpsing the archway to the room of machines and almost crying out as I saw the incline leading down to where one of those blasphemous trap-doors must be yawning two levels below. But instead of crying out I muttered over and over to myself that this was all a dream from which I must soon awake. Perhaps I was in camp — perhaps I was at home in Arkham. As these hopes bolstered up my sanity I began to mount the incline to the higher level.
I knew, of course, that I had the four-foot cleft to re-cross, yet was too racked by other fears to realise the full horror until I came almost upon it. On my descent, the leap across had been easy — but could I clear the gap as readily when going uphill, and hampered by fright, exhaustion, the weight of the metal case, and the anomalous backward tug of that daemon wind? I thought of these things at the last moment, and thought also of the nameless entities which might be lurking in the black abysses below the chasm.
My wavering torch was growing feeble, but I could tell by some obscure memory when I neared the cleft. The chill blasts of wind and the nauseous whistling shrieks behind me were for the moment like a merciful opiate, dulling my imagination to the horror of the yawning gulf ahead. And then I became aware of the added blasts and whistling in front of me — tides of abomination surging up through the cleft itself from depths unimagined and unimaginable.
