1Still another time have I come to a place where it is very difficult to proceed. I ought to be hardened by this stage; but there are some experiences and intimations which scar too deeply to permit of healing, and leave only such added sensitiveness that memory re-inspired all the original horror.

2We saw, as I have said, certain obstructions on the polished floor ahead; and I may add that our nostrils were assailed almost simultaneously by a very curious intensification of the strange, prevailing fetor, now quite plainly mixed with the nameless stench of those others which had gone before us.

3The light of the second torch left no doubt of what the obstructions were, and we dared approach them only because we could see, even from a distance, that they were quite as past all harming power as had been the six similar specimens unearthed from the monstrous star-mounded graves at poor Lake's camp.

4They were, indeed, as lacking in completeness as most of those we had unearthedthough it grew plain from the thick, dark-green pool gathering around them that their incompleteness was of infinitely greater recency. There seemed to be only four of them, whereas Lake's bulletins would have suggested no less than eight as forming the group which had preceded us. To find them in this state was wholly unexpected, and we wondered what sort of monstrous struggle had occurred down here in the dark.

5Penguins, attacked in a body, retaliate savagely with their beaks; and our ears now made certain the existence of a rookery far beyond. Had those others disturbed such a place and aroused murderous pursuit? The obstructions did not suggest it, for penguin beaks against the tough tissues Lake had dissected could hardly account for the terrible damage our approaching glance was beginning to make out. Besides, the huge blind birds we had seen appeared to be singularly peaceful.

6Had there, then, been a struggle among those others, and were the absent four responsible? If so, where were they? Were they close at hand and likely to form an immediate menace to us? We glanced anxiously at some of the smooth-floored lateral passages as we continued our slow and frankly reluctant approach.

7Whatever the conflict was, it had clearly been that which had frightened the penguins into their unaccustomed wandering. It must, then, have arisen near that faintly heard rookery in the incalculable gulf beyond, since there were no signs that any birds had normally dwelt here.

8Perhaps, we reflected, there had been a hideous running fight, with the weaker party seeking to get back to the cached sledges when their pursuers finished them. One could picture the demonic fray between namelessly monstrous entities as it surged out of the black abyss with great clouds of frantic penguins squawking and scurrying ahead.

9I say that we approached those sprawling and incomplete obstructions slowly and reluctantly. Would to Heaven we had never approached them at all, but had run back at top speed out of that blasphemous tunnel with the greasily smooth floors and the degenerate murals aping and mocking the things they had supersededrun back, before we had seen what we did see, and before our minds were burned with something which will never let us breathe easily again!

10Both of our torches were turned on the prostrate objects, so that we soon realized the dominant factor in their incompleteness. Mauled, compressed, twisted, and ruptured as they were, their chief common injury was total decapitation.

11From each one the tentacled starfish head had been removed; and as we drew near we saw that the manner of removal looked more like some hellish tearing or suction than like any ordinary form of cleavage.

12Their noisome dark-green ichor formed a large, spreading pool; but its stench was half overshadowed by that newer and stranger stench, here more pungent than at any other point along our route.

13Only when we had come very close to the sprawling obstructions could we trace that second, unexplainable fetor to any immediate sourceand the instant we did so Danforth, remembering certain very vivid sculptures of the Old Ones' history in the Permian Age one hundred and fifty million years ago, gave vent to a nerve-tortured cry which echoed hysterically through that vaulted and archaic passage with the evil, palimpsest carvings.

14I came only just short of echoing his cry myself; for I had seen those primal sculptures, too, and had shudderingly admired the way the nameless artist had suggested that hideous slime coating found on certain incomplete and prostrate Old Onesthose whom the frightful Shoggoths had characteristically slain and sucked to a ghastly headlessness in the great war of resubjugation.

15They were infamous, nightmare sculptures even when telling of age-old, bygone things; for Shoggoths and their work ought not to be seen by human beings or portrayed by any beings.

16The mad author of the Necronomicon had nervously tried to swear that none had been bred on this planet, and that only drugged dreamers had ever conceived them. Formless protoplasm able to mock and reflect all forms and organs and processesviscous agglutinations of bubbling cellsrubbery fifteen-foot spheroids infinitely plastic and ductileslaves of suggestion, builders of citiesmore and more sullen, more and more intelligent, more and more amphibious, more and more imitative! Great Heaven! What madness made even those blasphemous Old Ones willing to use and to carve such things?

17And now, when Danforth and I saw the freshly glistening and reflectively iridescent black slime which clung thickly to those headless bodies and stank obscenely with that new, unknown odor whose cause only a diseased fancy could envisageclung to those bodies and sparkled less voluminously on a smooth part of the accursedly resculptured wall in a series of grouped dotswe understood the quality of cosmic fear to its uttermost depths.

18It was not fear of those four missing othersfor all too well did we suspect they would do no harm again. Poor devils! After all, they were not evil things of their kind. They were the men of another age and another order of being. Nature had played a hellish jest on themas it will on any others that human madness, callousness, or cruelty may hereafter drag up in that hideously dead or sleeping polar wasteand this was their tragic homecoming.

19They had not been even savagesfor what indeed had they done? That awful awakening in the cold of an unknown epochperhaps an attack by the furry, frantically barking quadrupeds, and a dazed defense against them and the equally frantic white simians with the queer wrappings and paraphernalia! Poor Lake. Poor Gedney. And poor Old Ones! Scientists to the lastwhat had they done that we would not have done in their place? Lord, what intelligence and persistence! What a facing of the incredible, just as those carven kinsmen and forbears had faced things only a little less incredible! Radiates, vegetables, monstrosities, star spawnwhatever they had been, they were men!

20They had crossed the icy peaks on whose templed slopes they had once worshiped and roamed among the tree ferns. They had found their dead city brooding under its curse, and had read its carven latter days as we had done. They had tried to reach their living fellows in fabled depths of blackness they had never seenand what had they found?

21All this flashed in unison through the thoughts of Danforth and me as we looked from those headless, slime-coated shapes to the loathsome palimpsest sculptures and the diabolical dot groups of fresh slime on the wall beside themlooked and understood what must have triumphed and survived down there in the Cyclopean water city of that nighted, penguin-fringed abyss, whence even now a sinister curling mist had begun to belch pallidly as if in answer to Danforth's hysterical scream.

22The shock of recognizing that monstrous slime and headlessness had frozen us into mute, motionless statues, and it is only through later conversations that we have learned of the complete identity of our thoughts at that moment.

23It seemed æons that we stood there, but actually it could not have been more than ten or fifteen seconds. That hateful, pallid mist curled forward as if veritably driven by some remoter advancing bulkand then came a sound which upset much of what we had just decided, and in so doing broke the spell and enabled us to run like mad past squawking, confused penguins over our former trail back to the city, along ice-sunken megalithic corridors to the great open circle, and up that archaic spiral ramp in a frenzied, automatic plunge for the sane outer air and light of day.

24And then came a sounda horrible soundwhich enabled us to run like mad for the sane outer air——

25The new sound, as I have intimated, upset much that we had decided; because it was what poor Lake's dissection had led us to attribute to those we had just judged dead. It was, Danforth later told me, precisely what he had caught in infinitely muffled form when at that spot beyond the alley corner above the glacial level; and it certainly had a shocking resemblance to the wind pipings we had both heard around the lofty mountain caves.

26At the risk of seeming puerile I will add another thing, too, if only because of the surprising way Danforth's impression chimed with mine. Of course, common reading is what prepared us both to make the interpretation, though Danforth has hinted at queer notions about unsuspected and forbidden sources to which Poe may have had access when writing his "Arthur Gordon Pym" a century ago.

27It will be remembered that in that fantastic tale there is a word of unknown but terrible and prodigious significance connected with the antarctic and screamed eternally by the gigantic, spectrally snowy birds of that malign region's core. "Tekeli-li! Tekeli-li!" That, I may admit, is exactly what we thought we heard conveyed by that sudden sound behind the advancing white mistthat insidious, musical piping over a singularly wide range.

28We were in full flight before three notes or syllables had been uttered, though we knew that the swiftness of the Old Ones would enable any scream-roused and pursuing survivor of the slaughter to overtake us in a moment if it really wished to do so.

29We had a vague hope, however, that nonaggressive conduct and a display of kindred reason might cause such a being to spare us in case of capture, if only from scientific curiosity.

30After all, if such a one had nothing to fear for itself it would have no motive in harming us. Concealment being futile at this juncture, we used our torch for a running glance behind, and perceived that the mist was thinning. Would we see at last, a complete and living specimen of those others? Again came that insidious musical piping—"Tekeli-li! Tekeli-li!"

31Then, noting that we were actually gaining on our pursuer, it occurred to us that the entity might be wounded. We could take no chances, however, since it was very obviously approaching in answer to Danforth's scream, rather than in flight from any other entity. The timing was too close to admit of doubt.

32Of the whereabouts of that less conceivable and less mentionable nightmarethat fetid, unglimpsed mountain of slime-spewing protoplasm whose race had conquered the abyss and sent land pioneers to recarve and squirm through the burrows of the hillswe could form no guess; and it cost us a genuine pang to leave this probably crippled Old Oneperhaps a lone survivorto the peril of recapture and a nameless fate.

33Thank Heaven we did not slacken our run. The curling mist had thickened again, and was driving ahead with increased speed; whilst the straying penguins in our rear were squawking and screaming and displaying signs of a panic really surprising in view of their relatively minor confusion when we had passed them.

34Once more came that sinister, wide-ranged piping—"Tekeli-li! Tekeli-li!" We had been wrong. The thing was not wounded, but had merely paused on encountering the bodies of its fallen kindred and the hellish slime inscription above them. We could never know what that demon message wasbut those burials at Lake's camp had shown how much importance the beings attached to their dead.

35Our recklessly used torch now revealed ahead of us the large open cavern where various ways converged, and we were glad to be leaving those morbid palimpsest sculpturesalmost felt even when scarcely seenbehind.

36Another thought which the advent of the cave inspired was the possibility of losing our pursuer at this bewildering focus of large galleries. There were several of the blind albino penguins in the open space, and it seemed clear that their fear of the oncoming entity was extreme to the point of unaccountability.

37If at that point we dimmed our torch to the very lowest limit of traveling need, keeping it strictly in front of us, the frightened squawking motions of the huge birds in the mist might muffle our footfalls, screen our true course, and somehow set up a false lead.

38Amidst the churning, spiraling fog, the littered and unglistening floor of the main tunnel beyond this point, as differing from the other morbidly polished burrows, could hardly form a highly distinguishing feature; even, so far as we could conjecture, for those indicated special senses which made the Old Ones partly, though imperfectly, independent of light in emergencies.

39In fact, we were somewhat apprehensive lest we go astray ourselves in our haste. For we had, of course, decided to keep straight on toward the dead city; since the consequences of loss in those unknown foothill honeycombings would be unthinkable.

40The fact that we survived and emerged is sufficient proof that the thing did take a wrong gallery whilst we providentially hit on the right one. The penguins alone could not have saved us, but in conjunction with the mist they seem to have done so. Only a benign fate kept the curling vapors thick enough at the right moment, for they were constantly shifting and threatening to vanish.

41Indeed, they did lift for a second just before we emerged from the nauseously resculptured tunnel into the cave; so that we actually caught one first and only half glimpse of the oncoming entity as we cast a final, desperately fearful glance backward before dimming the torch and mixing with the penguins in the hope of dodging pursuit. If the fate which screened us was benign, that which gave us the half glimpse was infinitely the opposite; for to that flash of semivision can be traced a full half of the horror which has ever since haunted us.

42Our exact motive in looking back again was perhaps no more than the immemorial instinct of the pursued to gauge the nature and course of its pursuer; or perhaps it was an automatic attempt to answer a subconscious question raised by one of our senses.

43In the midst of our flight, with all our faculties centered on the problem of escape, we were in no condition to observe and analyze details; yet even so our latent brain cells must have wondered at the message brought them by our nostrils. Afterward, we realized what it wasthat our retreat from the fetid slime coating on those headless obstructions, and the coincident approach of the pursuing entity, had not brought us the exchange of stenches which logic called for.

44In the neighborhood of the prostrate things that new and lately unexplainable fetor had been wholly dominant; but by this time it ought to have largely given place to the nameless stench associated with those others. This it had not donefor instead, the newer and less bearable smell was now virtually undiluted, and growing more and more poisonously insistent each second.

45So we glanced backsimultaneously, it would appear; though no doubt the incipient motion of one prompted the imitation of the other. As we did so we flashed both torches full strength at the momentarily thinned mist; either from sheer primitive anxiety to see all we could, or in a less primitive but equally unconscious effort to dazzle the entity before we dimmed our light and dodged among the penguins of the labyrinth center ahead.

46Unhappy act! Not Orpheus himself, or Lot's wife, paid much more dearly for a backward glance. And again came that shocking, wide-ranged piping—"Tekeli-li! Tekeli-li!"

47Danforth was totally unstrung, and the first thing I remember of the rest of the journey was hearing him light-headedly chant a hysterical formula in which I alone of mankind could have found anything but insane irrelevance. It reverberated in falsetto echoes among the squawks of the penguins; reverberated through the vaulting ahead, andthank Heaventhrough the now empty vaultings behind. He could not have begun it at onceelse we would not have been alive and blindly racing. I shudder to think of what a shade of difference in his nervous reactions might have brought.

48"South Station UnderWashington UnderPark Street Under—Kendall—Central—Harvard——" The poor fellow was chanting the familiar stations of the Boston-Cambridge tunnel that burrowed through our peaceful native soil thousands of miles away in New England, yet to me the ritual had neither irrelevance nor home feeling. It had only horror, because I knew unerringly the monstrous, nefandous analogy that had suggested it.

49We had expected, upon looking back, to see a terrible and incredible moving entity if the mists were thin enough; but of that entity we had formed a clear idea. What we did seefor the mists were indeed all too malignly thinnedwas something altogether different, and immeasurably more hideous and detestable. It was the utter, objective embodiment of the fantastic novelist's 'thing that should not be'; and its nearest comprehensible analogue is a vast, onrushing subway train as one sees it from a station platformthe great black front looming colossally out of infinite subterraneous distance, constellated with strangely colored lights and filling the prodigious burrow.

50But we were not on a station platform. We were on the track ahead as the nightmare, plastic column of fetid black iridescence oozed tightly onward through its fifteen-foot sinus, gathering unholy speed and driving before it a spiral, rethickening cloud of the pallid abyss vapor.

51It was a terrible, indescribable thing, vaster than any subway traina shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unforming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter.

52Still came that eldritch, mocking cry—"Tekeli-li! Tekeli-li!" And at last we remembered that the demonic Shoggoths—given life, though, and plastic organ patterns solely by the Old Ones, and having no language save that which the dot groups expressedhad likewise no voice save the imitated accents of their bygone masters.
