It was on Monday, June 3, that we saw the first of the half-buried blocks. I cannot describe the emotions with which I actually touched — in objective reality — a fragment of Cyclopean masonry in every respect like the blocks in the walls of my dream-buildings. There was a distinct trace of carving — and my hands trembled as I recognised part of a curvilinear decorative scheme made hellish to me through years of tormenting nightmare and baffling research.
A month of digging brought a total of some 1250 blocks in varying stages of wear and disintegration. Most of these were carven megaliths with curved tops and bottoms. A minority were smaller, flatter, plain-surfaced, and square or octagonally cut — like those of the floors and pavements in my dreams — while a few were singularly massive and curved or slanted in such a manner as to suggest use in vaulting or groining, or as parts of arches or round window casings. The deeper — and the farther north and east — we dug, the more blocks we found; though we still failed to discover any trace of arrangement among them. Professor Dyer was appalled at the measureless age of the fragments, and Freeborn found traces of symbols which fitted darkly into certain Papuan and Polynesian legends of infinite antiquity. The condition and scattering of the blocks told mutely of vertiginous cycles of time and geologic upheavals of cosmic savagery.
We had an aëroplane with us, and my son Wingate would often go up to different heights and scan the sand-and-rock waste for signs of dim, large-scale outlines — either differences of level or trails of scattered blocks. His results were virtually negative; for whenever he would one day think he had glimpsed some significant trend, he would on his next trip find the impression replaced by another equally insubstantial — a result of the shifting, wind-blown sand. One or two of these ephemeral suggestions, though, affected me queerly and disagreeably. They seemed, after a fashion, to dovetail horribly with something which I had dreamed or read, but which I could no longer remember. There was a terrible pseudo-familiarity about them — which somehow made me look furtively and apprehensively over the abominable, sterile terrain toward the north and northeast.
Around the first week in July I developed an unaccountable set of mixed emotions about that general northeasterly region. There was horror, and there was curiosity — but more than that, there was a persistent and perplexing illusion of memory. I tried all sorts of psychological expedients to get these notions out of my head, but met with no success. Sleeplessness also gained upon me, but I almost welcomed this because of the resultant shortening of my dream-periods. I acquired the habit of taking long, lone walks in the desert late at night — usually to the north or northeast, whither the sum of my strange new impulses seemed subtly to pull me.
Sometimes, on these walks, I would stumble over nearly buried fragments of the ancient masonry. Though there were fewer visible blocks here than where we had started, I felt sure that there must be a vast abundance beneath the surface. The ground was less level than at our camp, and the prevailing high winds now and then piled the sand into fantastic temporary hillocks — exposing some traces of the elder stones while it covered other traces. I was queerly anxious to have the excavations extend to this territory, yet at the same time dreaded what might be revealed. Obviously, I was getting into a rather bad state — all the worse because I could not account for it.
An indication of my poor nervous health can be gained from my response to an odd discovery which I made on one of my nocturnal rambles. It was on the evening of July 11th, when a gibbous moon flooded the mysterious hillocks with a curious pallor. Wandering somewhat beyond my usual limits, I came upon a great stone which seemed to differ markedly from any we had yet encountered. It was almost wholly covered, but I stooped and cleared away the sand with my hands, later studying the object carefully and supplementing the moonlight with my electric torch. Unlike the other very large rocks, this one was perfectly square-cut, with no convex or concave surface. It seemed, too, to be of a dark basaltic substance wholly dissimilar to the granite and sandstone and occasional concrete of the now familiar fragments.
Suddenly I rose, turned, and ran for the camp at top speed. It was a wholly unconscious and irrational flight, and only when I was close to my tent did I fully realise why I had run. Then it came to me. The queer dark stone was something which I had dreamed and read about, and which was linked with the uttermost horrors of the aeon-old legendry. It was one of the blocks of that basaltic elder masonry which the fabled Great Race held in such fear — the tall, windowless ruins left by those brooding, half-material, alien Things that festered in earth’s nether abysses and against whose wind-like, invisible forces the trap-doors were sealed and the sleepless sentinels posted.
