The decadent cartouches and dadoes telling this story were, as I have said, the latest we could find in our limited search. They left us with a picture of the Old Ones shuttling back and forth betwixt the land city in summer and the sea-cavern city in winter, and sometimes trading with the sea-bottom cities off the antarctic coast. By this time the ultimate doom of the land city must have been recognised, for the sculptures shewed many signs of the cold’s malign encroachments. Vegetation was declining, and the terrible snows of the winter no longer melted completely even in midsummer. The saurian livestock were nearly all dead, and the mammals were standing it none too well. To keep on with the work of the upper world it had become necessary to adapt some of the amorphous and curiously cold-resistant shoggoths to land life; a thing the Old Ones had formerly been reluctant to do. The great river was now lifeless, and the upper sea had lost most of its denizens except the seals and whales. All the birds had flown away, save only the great, grotesque penguins.
What had happened afterward we could only guess. How long had the new sea-cavern city survived? Was it still down there, a stony corpse in eternal blackness? Had the subterranean waters frozen at last? To what fate had the ocean-bottom cities of the outer world been delivered? Had any of the Old Ones shifted north ahead of the creeping ice-cap? Existing geology shews no trace of their presence. Had the frightful Mi-Go been still a menace in the outer land world of the north? Could one be sure of what might or might not linger even to this day in the lightless and unplumbed abysses of earth’s deepest waters? Those things had seemingly been able to withstand any amount of pressure—and men of the sea have fished up curious objects at times. And has the killer-whale theory really explained the savage and mysterious scars on antarctic seals noticed a generation ago by Borchgrevingk?
The specimens found by poor Lake did not enter into these guesses, for their geologic setting proved them to have lived at what must have been a very early date in the land city’s history. They were, according to their location, certainly not less than thirty million years old; and we reflected that in their day the sea-cavern city, and indeed the cavern itself, had no existence. They would have remembered an older scene, with lush Tertiary vegetation everywhere, a younger land city of flourishing arts around them, and a great river sweeping northward along the base of the mighty mountains toward a far-away tropic ocean.
And yet we could not help thinking about these specimens—especially about the eight perfect ones that were missing from Lake’s hideously ravaged camp. There was something abnormal about that whole business—the strange things we had tried so hard to lay to somebody’s madness—those frightful graves—the amount and nature of the missing material—Gedney—the unearthly toughness of those archaic monstrosities, and the queer vital freaks the sculptures now shewed the race to have. … Danforth and I had seen a good deal in the last few hours, and were prepared to believe and keep silent about many appalling and incredible secrets of primal Nature.
IX.
I have said that our study of the decadent sculptures brought about a change in our immediate objective. This of course had to do with the chiselled avenues to the black inner world, of whose existence we had not known before, but which we were now eager to find and traverse. From the evident scale of the carvings we deduced that a steeply descending walk of about a mile through either of the neighbouring tunnels would bring us to the brink of the dizzy sunless cliffs above the great abyss; down whose side adequate paths, improved by the Old Ones, led to the rocky shore of the hidden and nighted ocean. To behold this fabulous gulf in stark reality was a lure which seemed impossible of resistance once we knew of the thing—yet we realised we must begin the quest at once if we expected to include it on our present flight.
It was now 8 p.m., and we had not enough battery replacements to let our torches burn on forever. We had done so much of our studying and copying below the glacial level that our battery supply had had at least five hours of nearly continuous use; and despite the special dry cell formula would obviously be good for only about four more—though by keeping one torch unused, except for especially interesting or difficult places, we might manage to eke out a safe margin beyond that. It would not do to be without a light in these Cyclopean catacombs, hence in order to make the abyss trip we must give up all further mural deciphering. Of course we intended to revisit the place for days and perhaps weeks of intensive study and photography—curiosity having long ago got the better of horror—but just now we must hasten. Our supply of trail-blazing paper was far from unlimited, and we were reluctant to sacrifice spare notebooks or sketching paper to augment it; but we did let one large notebook go. If worst came to worst, we could resort to rock-chipping—and of course it would be possible, even in case of really lost direction, to work up to full daylight by one channel or another if granted sufficient time for plentiful trial and error. So at last we set off eagerly in the indicated direction of the nearest tunnel.
According to the carvings from which we had made our map, the desired tunnel-mouth could not be much more than a quarter-mile from where we stood; the intervening space shewing solid-looking buildings quite likely to be penetrable still at a sub-glacial level. The opening itself would be in the basement—on the angle nearest the foothills—of a vast five-pointed structure of evidently public and perhaps ceremonial nature, which we tried to identify from our aërial survey of the ruins. No such structure came to our minds as we recalled our flight, hence we concluded that its upper parts had been greatly damaged, or that it had been totally shattered in an ice-rift we had noticed. In the latter case the tunnel would probably turn out to be choked, so that we would have to try the next nearest one—the one less than a mile to the north. The intervening river-course prevented our trying any of the more southerly tunnels on this trip; and indeed, if both of the neighbouring ones were choked it was doubtful whether our batteries would warrant an attempt on the next northerly one—about a mile beyond our second choice.
As we threaded our dim way through the labyrinth with the aid of map and compass—traversing rooms and corridors in every stage of ruin or preservation, clambering up ramps, crossing upper floors and bridges and clambering down again, encountering choked doorways and piles of debris, hastening now and then along finely preserved and uncannily immaculate stretches, taking false leads and retracing our way (in such cases removing the blind paper trail we had left), and once in a while striking the bottom of an open shaft through which daylight poured or trickled down—we were repeatedly tantalised by the sculptured walls along our route. Many must have told tales of immense historical importance, and only the prospect of later visits reconciled us to the need of passing them by. As it was, we slowed down once in a while and turned on our second torch. If we had had more films we would certainly have paused briefly to photograph certain bas-reliefs, but time-consuming hand copying was clearly out of the question.
I come now once more to a place where the temptation to hesitate, or to hint rather than state, is very strong. It is necessary, however, to reveal the rest in order to justify my course in discouraging further exploration. We had wormed our way very close to the computed site of the tunnel’s mouth—having crossed a second-story bridge to what seemed plainly the tip of a pointed wall, and descended to a ruinous corridor especially rich in decadently elaborate and apparently ritualistic sculptures of late workmanship—when, about 8:30 p.m., Danforth’s keen young nostrils gave us the first hint of something unusual. If we had had a dog with us, I suppose we would have been warned before. At first we could not precisely say what was wrong with the formerly crystal-pure air, but after a few seconds our memories reacted only too definitely. Let me try to state the thing without flinching. There was an odour—and that odour was vaguely, subtly, and unmistakably akin to what had nauseated us upon opening the insane grave of the horror poor Lake had dissected.
Of course the revelation was not as clearly cut at the time as it sounds now. There were several conceivable expla
nations, and we did a good deal of indecisive whispering. Most important of all, we did not retreat without further investigation; for having come this far, we were loath to be balked by anything short of certain disaster. Anyway, what we must have suspected was altogether too wild to believe. Such things did not happen in any normal world. It was probably sheer irrational instinct which made us dim our single torch—tempted no longer by the decadent and sinister sculptures that leered menacingly from the oppressive walls—and which softened our progress to a cautious tiptoeing and crawling over the increasingly littered floor and heaps of debris.
Danforth’s eyes as well as nose proved better than mine, for it was likewise he who first noticed the queer aspect of the debris after we had passed many half-choked arches leading to chambers and corridors on the ground level. It did not look quite as it ought after countless thousands of years of desertion, and when we cautiously turned on more light we saw that a kind of swath seemed to have been lately tracked through it. The irregular nature of the litter precluded any definite marks, but in the smoother places there were suggestions of the dragging of heavy objects. Once we thought there was a hint of parallel tracks, as if of runners. This was what made us pause again.
It was during that pause that we caught—simultaneously this time—the other odour ahead. Paradoxically, it was both a less frightful and a more frightful odour—less frightful intrinsically, but infinitely appalling in this place under the known circumstances … unless, of course, Gedney. … For the odour was the plain and familiar one of common petrol—every-day gasoline.
Our motivation after that is something I will leave to psychologists. We knew now that some terrible extension of the camp horrors must have crawled into this nighted burial-place of the aeons, hence could not doubt any longer the existence of nameless conditions—present or at least recent—just ahead. Yet in the end we did let sheer burning curiosity—or anxiety—or auto-hypnotism—or vague thoughts of responsibility toward Gedney—or what not—drive us on. Danforth whispered again of the print he thought he had seen at the alley-turning in the ruins above; and of the faint musical piping—potentially of tremendous significance in the light of Lake’s dissection report despite its close resemblance to the cave-mouth echoes of the windy peaks—which he thought he had shortly afterward half heard from unknown depths below. I, in my turn, whispered of how the camp was left—of what had disappeared, and of how the madness of a lone survivor might have conceived the inconceivable—a wild trip across the monstrous mountains and a descent into the unknown primal masonry—
But we could not convince each other, or even ourselves, of anything definite. We had turned off all light as we stood still, and vaguely noticed that a trace of deeply filtered upper day kept the blackness from being absolute. Having automatically begun to move ahead, we guided ourselves by occasional flashes from our torch. The disturbed debris formed an impression we could not shake off, and the smell of gasoline grew stronger. More and more ruin met our eyes and hampered our feet, until very soon we saw that the forward way was about to cease. We had been all too correct in our pessimistic guess about that rift glimpsed from the air. Our tunnel quest was a blind one, and we were not even going to be able to reach the basement out of which the abyssward aperture opened.
The torch, flashing over the grotesquely carven walls of the blocked corridor in which we stood, shewed several doorways in various states of obstruction; and from one of them the gasoline odour—quite submerging that other hint of odour—came with especial distinctness. As we looked more steadily, we saw that beyond a doubt there had been a slight and recent clearing away of debris from that particular opening. Whatever the lurking horror might be, we believed the direct avenue toward it was now plainly manifest. I do not think anyone will wonder that we waited an appreciable time before making any further motion.
And yet, when we did venture inside that black arch, our first impression was one of anticlimax. For amidst the littered expanse of that sculptured crypt—a perfect cube with sides of about twenty feet—there remained no recent object of instantly discernible size; so that we looked instinctively, though in vain, for a farther doorway. In another moment, however, Danforth’s sharp vision had descried a place where the floor debris had been disturbed; and we turned on both torches full strength. Though what we saw in that light was actually simple and trifling, I am none the less reluctant to tell of it because of what it implied. It was a rough levelling of the debris, upon which several small objects lay carelessly scattered, and at one corner of which a considerable amount of gasoline must have been spilled lately enough to leave a strong odour even at this extreme super-plateau altitude. In other words, it could not be other than a sort of camp—a camp made by questing beings who like us had been turned back by the unexpectedly choked way to the abyss.
Let me be plain. The scattered objects were, so far as substance was concerned, all from Lake’s camp; and consisted of tin cans as queerly opened as those we had seen at that ravaged place, many spent matches, three illustrated books more or less curiously smudged, an empty ink bottle with its pictorial and instructional carton, a broken fountain pen, some oddly snipped fragments of fur and tent-cloth, a used electric battery with circular of directions, a folder that came with our type of tent heater, and a sprinkling of crumpled papers. It was all bad enough, but when we smoothed out the papers and looked at what was on them we felt we had come to the worst. We had found certain inexplicably blotted papers at the camp which might have prepared us, yet the effect of the sight down there in the pre-human vaults of a nightmare city was almost too much to bear.
A mad Gedney might have made the groups of dots in imitation of those found on the greenish soapstones, just as the dots on those insane five-pointed grave-mounds might have been made; and he might conceivably have prepared rough, hasty sketches—varying in their accuracy or lack of it—which outlined the neighbouring parts of the city and traced the way from a circularly represented place outside our previous route—a place we identified as a great cylindrical tower in the carvings and as a vast circular gulf glimpsed in our aërial survey—to the present five-pointed structure and the tunnel-mouth therein. He might, I repeat, have prepared such sketches; for those before us were quite obviously compiled as our own had been from late sculptures somewhere in the glacial labyrinth, though not from the ones which we had seen and used. But what this art-blind bungler could never have done was to execute those sketches in a strange and assured technique perhaps superior, despite haste and carelessness, to any of the decadent carvings from which they were taken—the characteristic and unmistakable technique of the Old Ones themselves in the dead city’s heyday.
There are those who will say Danforth and I were utterly mad not to flee for our lives after that; since our conclusions were now—notwithstanding their wildness—completely fixed, and of a nature I need not even mention to those who have read my account as far as this. Perhaps we were mad—for have I not said those horrible peaks were mountains of madness? But I think I can detect something of the same spirit—albeit in a less extreme form—in the men who stalk deadly beasts through African jungles to photograph them or study their habits. Half-paralysed with terror though we were, there was nevertheless fanned within us a blazing flame of awe and curiosity which triumphed in the end.
Of course we did not mean to face that—or those—which we knew had been there, but we felt that they must be gone by now. They would by this time have found the other neighbouring entrance to the abyss, and have passed within to whatever night-black fragments of the past might await them in the ultimate gulf—the ultimate gulf they had never seen. Or if that entrance, too, was blocked, they would have gone on to the north seeking another. They were, we remembered, partly independent of light.
Looking back to that moment, I can scarcely recall just what precise form our new emotions took—just what change of immediate objective it was that so sharpened our sense of expectancy. We certainly did not mean to face wh
at we feared—yet I will not deny that we may have had a lurking, unconscious wish to spy certain things from some hidden vantage-point. Probably we had not given up our zeal to glimpse the abyss itself, though there was interposed a new goal in the form of that great circular place shewn on the crumpled sketches we had found. We had at once recognised it as a monstrous cylindrical tower figuring in the very earliest carvings, but appearing only as a prodigious round aperture from above. Something about the impressiveness of its rendering, even in these hasty diagrams, made us think that its sub-glacial levels must still form a feature of peculiar importance. Perhaps it embodied architectural marvels as yet unencountered by us. It was certainly of incredible age according to the sculptures in which it figured—being indeed among the first things built in the city. Its carvings, if preserved, could not but be highly significant. Moreover, it might form a good present link with the upper world—a shorter route than the one we were so carefully blazing, and probably that by which those others had descended.
At any rate, the thing we did was to study the terrible sketches—which quite perfectly confirmed our own—and start back over the indicated course to the circular place; the course which our nameless predecessors must have traversed twice before us. The other neighbouring gate to the abyss would lie beyond that. I need not speak of our journey—during which we continued to leave an economical trail of paper—for it was precisely the same in kind as that by which we had reached the cul de sac; except that it tended to adhere more closely to the ground level and even descend to basement corridors. Every now and then we could trace certain disturbing marks in the debris or litter under foot; and after we had passed outside the radius of the gasoline scent we were again faintly conscious—spasmodically—of that more hideous and more persistent scent. After the way had branched from our former course we sometimes gave the rays of our single torch a furtive sweep along the walls; noting in almost every case the well-nigh omnipresent sculptures, which indeed seem to have formed a main aesthetic outlet for the Old Ones.
