So we glanced back simultaneously, 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. Unhappy 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!"

I might as well be frank – even if I cannot bear to be quite direct – in stating what we saw; though at the time we felt that it was not to be admitted even to each other. The words reaching the reader can never even suggest the awfulness of the sight itself. It crippled our consciousness so completely that I wonder we had the residual sense to dim our torches as planned, and to strike the right tunnel toward the dead city. Instinct alone must have carried us through – perhaps better than reason could have done; though if that was what saved us, we paid a high price. Of reason we certainly had little enough left.

Danforth was totally unstrung, and the first thing I remember of the rest of the journey was hearing him lightheadedly chant an 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 vaultings ahead, and-thank God-through the now empty vaultings behind. He could not have begun it at once – else 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.

"South Station Under – Washington Under – Park 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. We 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 see – for the mists were indeed all too malignly thinned – was 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 platform – the great black front looming colossally out of infinite subterranean distance, constellated with strangely colored lights and filling the prodigious burrow as a piston fills a cylinder.

But 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. It was a terrible, indescribable thing vaster than any subway train – a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and un-forming 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. Still came that eldritch, mocking cry– "Tekeli-li! Tekeli-li!" and at last we remembered that the demoniac Shoggoths – given life, thought, and plastic organ patterns solely by the Old Ones, and having no language save that which the dot groups expressed – had likewise no voice save the imitated accents of their bygone masters.

Danforth and I have recollections of emerging into the great sculptured hemisphere and of threading our back trail through the Cyclopean rooms and corridors of the dead city; yet these are purely dream fragments involving no memory of volition, details, or physical exertion. It was as if we floated in a nebulous world or dimension without time, causation, or orientation. The gray half-daylight of the vast circular space sobered us somewhat; but we did not go near those cached sledges or look again at poor Gedney and the dog. They have a strange and titanic mausoleum, and I hope the end of this planet will find them still undisturbed.

It was while struggling up the colossal spiral incline that we first felt the terrible fatigue and short breath which our race through the thin plateau air had produced; but not even fear of collapse could make us pause before reaching the normal outer realm of sun and sky. There was something vaguely appropriate about our departure from those buried epochs; for as we wound our panting way up the sixty-foot cylinder of primal masonry, we glimpsed beside us a continuous procession of heroic sculptures in the dead race's early and undecayed technique – a farewell from the Old Ones, written fifty million years ago.

Finally scrambling out at the top, we found ourselves on a great mound of tumbled blocks, with the curved walls of higher stonework rising westward, and the brooding peaks of the great mountains showing beyond the more crumbled structures toward the east. The low antarctic sun of midnight peered redly from the southern horizon through rifts in the jagged ruins, and the terrible age and deadness of the nightmare city seemed all the starker by contrast with such relatively known and accustomed things as the features of the polar landscape. The sky above was a churning and opalescent mass of tenuous ice-vapors, and the cold clutched at our vitals. Wearily resting the outfit-bags to which we had instinctively clung throughout our desperate flight, we rebuttoned our heavy garments for the stumbling climb down the mound and the walk through the aeon-old stone maze to the foothills where our aeroplane waited. Of what had set us fleeing from that darkness of earth's secret and archaic gulfs we said nothing at all.

In less than a quarter of an hour we had found the steep grade to the foothills-the probable ancient terrace – by which we had descended, and could see the dark bulk of our great plane amidst the sparse ruins on the rising slope ahead. Halfway uphill toward our goal we paused for a momentary breathing spell, and turned to look again at the fantastic tangle of incredible stone shapes below us-once more outlined mystically against an unknown west. As we did so we saw that the sky beyond had lost its morning haziness; the restless ice-vapors having moved up to the zenith, where their mocking outlines seemed on the point of settling into some bizarre pattern which they feared to make quite definite or conclusive.

There now lay revealed on the ultimate white horizon behind the grotesque city a dim, elfin line of pinnacled violet whose needle-pointed heights loomed dreamlike against the beckoning rose color of the western sky. Up toward this shimmering rim sloped the ancient table-land, the depressed course of the bygone river traversing it as an irregular ribbon of shadow. For a second we gasped in admiration of the scene's unearthly cosmic beauty, and then vague horror began to creep into our souls. For this far violet line could be nothing else than the terrible mountains of the forbidden land – highest of earth's peaks and focus of earth's evil; harborers of nameless horrors and Archaean secrets; shunned and prayed to by those who feared to carve their meaning; untrodden by any living thing on earth, but visited by the sinister lightnings and sending strange beams across the plains in the polar night – beyond doubt the unknown archetype of that dreaded Kadath in the Cold Waste beyond abhorrent Leng, whereof primal legends hint evasively.
