These possible lines of foot-square impressions appeared to lead in two directions, as if something had gone somewhere and returned. They were, of course, very faint, and may have been illusions or accidents; but there was an element of dim, fumbling terror about the way I thought they ran. For at one end of them was the heap of cases which must have clattered down not long before, while at the other end was the ominous trapdoor with the cool, damp wind, yawning unguarded down to abysses past imagination.

That my strange sense of compulsion was deep and overwhelming is shown by its conquest of my fear. No rational motive could have drawn me on after that hideous suspicion of prints and the creeping dream memories it excited. Yet my right hand, even as it shook with fright, still twitched rhythmically in its eagerness to turn a lock it hoped to find. Before I knew it I was past the heap of lately fallen cases and running on tiptoe through aisles of utterly unbroken dust towards a point which I seemed to know morbidly, horribly well.
My mind was asking itself questions whose origin and relevancy I was only beginning to guess. Would the shelf be reachable by a human body? Could my human hand master all the aeon-remembered motions of the lock? Would the lock be undamaged and workable? And what would I do - what dare I do - with what - as I now commenced to realise - I both hoped and feared to find? Would it prove the awesome, brain-shattering truth of something past normal conception, or show only that I was dreaming?
The next I knew I had ceased my tiptoed racing and was standing still, staring at a row of maddeningly familiar hieroglyphed shelves. They were in a state of almost perfect preservation, and only three of the doors in this vicinity had sprung open.
My feelings towards these shelves cannot be described - so utter and insistent was the sense of old acquaintance. I was looking high up at a row near the top and wholly out of my reach, and wondering how I could climb to best advantage. An open door four rows from the bottom would help, and the locks of the closed doors formed possible holds for hands and feet. I would grip the torch between my teeth, as I had in other places where both hands were needed. Above all I must make no noise.
How to get down what I wished to remove would be difficult, but I could probably hook its movable fastener in my coat collar and carry it like a knapsack. Again I wondered whether the lock would be undamaged. That I could repeat each familiar motion I had not the least doubt. But I hoped the thing would not scrape or creak - and that my hand could work it properly.
Even as I thought these things I had taken the torch in my mouth and began to climb. The projecting locks were poor supports; but, as I had expected, the opened shelf helped greatly. I used both the swinging door and the edge of the aperture itself in my ascent, and managed to avoid any loud creaking.
Balanced on the upper edge of the door, and leaning far to my right, I could just reach the lock I sought. My fingers, half numb from climbing, were very clumsy at first; but I soon saw that they were anatomically adequate. And the memory rhythm was strong in them.
Out of unknown gulfs of time the intricate secret motions had somehow reached my brain correctly in every detail - for after less than five minutes of trying there came a click whose familiarity was all the more startling because I had not consciously anticipated it. In another instant the metal door was slowly swinging open with only the faintest grating sound.
Dazedly I looked over the row of greyish case ends thus exposed, and felt a tremendous surge of some wholly inexplicable emotion. Just within reach of my right hand was a case whose curving hieroglyphs made me shake with a pang infinitely more complex than one of mere fright. Still shaking, I managed to dislodge it amidst a shower of gritty flakes, and ease it over towards myself without any violent noise.
Like the other case I had handled, it was slightly more than twenty by fifteen inches in size, with curved mathematical designs in low relief. In thickness it just exceeded three inches.
Crudely wedging it between myself and the surface I was climbing, I fumbled with the fastener and finally got the hook free. Lifting the cover, I shifted the heavy object to my back, and let the hook catch hold of my collar. Hands now free, I awkwardly clambered down to the dusty floor and prepared to inspect my prize.
Kneeling in the gritty dust, I swung the case around and rested it in front of me. My hands shook, and I dreaded to draw out the book within almost as much as I longed - and felt compelled - to do so. It had very gradually become clear to me what I ought to find, and this realisation nearly paralysed my faculties.
If the thing were there - and if I were not dreaming - the implications would be quite beyond the power of the human spirit to bear. What tormented me most was my momentary inability to feel that my surroundings were a dream. The sense of reality was hideous - and again becomes so as I recall the scene.
At length I tremblingly pulled the book from its container and stared fascinatedly at the well-known hierogylphs on the cover. It seemed to be in prime condition, and the curvilinear letters of the title held me in almost as hypnotised a state as if I could read them. Indeed, I cannot swear that I did not actually read them in some transient and terrible access of abnormal memory.
I do not know how long it was before I dared to lift that thin metal cover. I temporised and made excuses to myself. I took the torch from my mouth and shut it off to save the battery. Then, in the dark, I collected my courage - finally lifting the cover without turning on the light. Last of all, I did indeed flash the torch upon the exposed page - steeling myself in advance to suppress any sound no matter what I should find.
I looked for an instant, then collapsed. Clenching my teeth, however, I kept silent. I sank wholly to the floor and put a hand to my forehead amidst the engulfing blackness. What I dreaded and expected was there. Either I was dreaming, or time and space had become a mockery.
I must be dreaming - but I would test the horror by carrying this thing back and showing it to my son if it were indeed a reality. My head swam frightfully, even though there were no visible objects in the unbroken gloom to swirl about me. Ideas and images of the starkest terror - excited by the vistas which my glimpse had opened up - began to throng in upon me and cloud my senses.
I thought of those possible prints in the dust, and trembled at the sound of my own breathing as I did so. Once again I flashed on the light and looked at the page as a serpent’s victim may look at his destroyer’s eyes and fangs.
Then, with clumsy fingers, in the dark, I closed the book, put it in its container, and snapped the lid and the curious, hooked fastener. This was what I must carry back to the outer world if it truly existed - if the whole abyss truly existed - if I, and the world itself, truly existed.
Just when I tottered to my feet and commenced my return I cannot be certain. It comes to me oddly - as a measure of my sense of separation from the normal world - that I did not even once look at my watch during those hideous hours underground.
Torch in hand, and with the ominous case under one arm, I eventually found myself tiptoeing in a kind of silent panic past the draught-giving abyss and those lurking suggestions of prints. I lessened my precautions as I climbed up the endless inclines, but could not shake off a shadow of apprehension which I had not felt on the downward journey.
I dreaded having to repass through that black basalt crypt that was older than the city itself, where cold draughts welled up from unguarded depths. I thought of that which the Great Race had feared, and of what might still be lurking - be it ever so weak and dying - down there. I thought of those five-circle prints and of what my dreams had told me of such prints - and of strange winds and whistling noises associated with them. And I thought of the tales of the modern blackfellows, wherein the horror of great winds and nameless ruins was dwelt upon.
I knew from a carven wall symbol the right floor to enter, and came at last - after passing that other book I had examined - to the great circular space with the branching archways. On my right, and at once recognisable, was the arch through which I ha
d arrived. This I now entered, conscious that the rest of my course would be harder because of the tumbled state of the masonry outside the archive building. My new metal-cased burden weighed upon me, and I found it harder and harder to be quiet as I stumbled among debris and fragments of every sort.
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 afterwards the slipping of blocks under my feet raised a sudden unprecedented din.
That 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. If so, what followed has a grim irony - 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 shows 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 blackness. 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 trapdoors 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 recross, 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 demon 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 whistlings in front of me - tides of abomination surging up through the cleft itself from depths unimagined and unimaginable.
Now, indeed, the essence of pure nightmare was upon me. Sanity departed - and, ignoring everything except the animal impulse of flight, I merely struggled and plunged upwards over the incline’s debris as if no gulf had existed. Then I saw the chasm’s edge, leaped frenziedly with every ounce of strength I possessed, and was instantly engulfed in a pandemoniac vortex of loathsome sound and utter, materially tangible blackness.
That is the end of my experience, so far as I can recall. Any further impressions belong wholly to the domain of phantasmagoric delirium. Dream, madness, and memory merged wildly together in a series of fantastic, fragmentary delusions which can have no relation to anything real.
There was a hideous fall through incalculable leagues of viscous, sentient darkness, and a babel of noises utterly alien to all that we know of the Earth and its organic life. Dormant, rudimentary senses seemed to start into vitality within me, telling of pits and voids peopled by floating horrors and leading to sunless crags and oceans and teeming cities of windowless, basalt towers upon which no light ever shone.
Secrets of the primal planet and its immemorial aeons flashed through my brain without the aid of sight or sound, and there were known to me things which not even the wildest of former dreams had ever suggested. And all the while cold fingers of damp vapour clutched and picked at me, and that eldritch, damnable whistling shrieked fiendishly above all the alternations of babel and silence in the whirlpools of darkness around.
Afterwards there were visions of the cyclopean city of my dreams - not in ruins, but just as I had dreamed of it. I was in my conical, non-human body again, and mingled with crowds of the Great Race and the captive minds who carried books up and down the lofty corridors and vast inclines.
Then, superimposed upon these pictures, were frightful, momentary flashes of a non-visual consciousness involving desperate struggles, a writhing free from clutching tentacles of whistling wind, an insane, bat-like flight through half-solid air, a feverish burrowing through the cyclone-whipped dark, and a wild stumbling and scrambling over fallen masonry.
Once there was a curious, intrusive flash of half sight - a faint, diffuse suspicion of bluish radiance far overhead. Then there came a dream of wind-pursued climbing and crawling - of wriggling into a blaze of sardonic moonlight through a jumble of debris which slid and collapsed after me amidst a morbid hurricane. It was the evil, monotonous beating of that maddening moonlight which at last told me of the return of what I had once known as the objective, waking world.
I was clawing prone through the sands of the Australian desert, and around me shrieked such a tumult of wind as I had never before known on our planet’s surface. My clothing was in rags, and my whole body was a mass of bruises and scratches.
Full consciousness returned very slowly, and at no time could I tell just where delirious dream left off and true memory began. There had seemed to be a mound of titan blocks, an abyss beneath it, a monstrous revelation from the past, and a nightmare horror at the end - but how much of this was real?
 
; My flashlight was gone, and likewise my metal case I may have discovered. Had there been such a case - or any abyss - or any mound? Raising my head, I looked behind me, and saw only the sterile, undulating sands of the desert.
The demon wind died down, and the bloated, fungoid moon sank reddeningly in the west. I lurched to my feet and began to stagger south-west towards the camp. What in truth had happened to me? Had I merely collapsed in the desert and dragged a dream-racked body over miles of sand and buried blocks? If not, how could I bear to live any longer?
For, in this new doubt, all my faith in the myth-born unreality of my visions dissolved once more into the hellish older doubting. If that abyss was real, then the Great Race was real - and its blasphemous reachings and seizures in the cosmos-wide vortex of time were no myths or nightmares, but a terrible, soul-shattering actuality.
Had I, in full, hideous fact, been drawn back to a prehuman world of a hundred and fifty million years ago in those dark, baffling days of the amnesia? Had my present body been the vehicle of a frightful alien consciousness from paleogean gulfs of time?
