They were like fantastic monolithic tapers; but their luminosity failed to reveal the giddy depth above and beneath.

He met none of the Oumnis in this inexhaustible world of night and silence. But after he had rounded the great gulf, and had started to re-ascend in smaller caverns, he began to encounter, at intervals, certain blind, white, repulsive creatures the size of an overgrown rat, but without even the rudiments of tail or legs. In his demoralized condition of mind and body, he felt a primitive fear of these things, rather than the mere repugnance which their aspect would normally have aroused. However, they were non-aggressive and shrank sluggishly away from him. Once, he trod inadvertently on one of the creatures and leapt away, howling with fright, when it squirmed nauseously beneath his heel. Finding he had crushed its head, he took courage and began to belabor the flopping abnormality with the metal rod which he still carried. He mashed it into an oozy pulp—a pulp that still quivered with life; and then, overcome by bestial, atavistic hunger, and forgetting all the painfully acquired prejudices of civilized man, he knelt down and devoured the pulp with shameless greed. Afterward, replete, he stretched himself out and slept for many hours.

He awoke with renewed physical strength, but with nerves and mind that were still partially shattered by his experiences. Like a savage who awakens in some primordial cave, he felt the irrational terror of darkness and mystery. His memories were dazed and broken, and he could recall the Oumnis only as a vague and almost supernatural source of fear, from which he had fled.

The fungus-bough, which had served him in lieu of a torch or lantern, was lying beside him in the darkness. With the bough in one hand and the metal rod in the other, he resumed his wanderings. He met more of the white, legless creatures; but he had conquered his fear of them now, and looked upon them only as a possible source of food. He proceeded to kill and eat one of them anon, relishing the worm-soft flesh as an aborigine would have relished a meal of grubs or white ants.

He had lost all notion of the passing of time or its measurement. He was a thing that clambered endlessly on Tartarean cavern-slopes or along the brink of lightless rivers and pools and chasms, killing when he was hungry, sleeping when his weariness became too urgent. Perhaps he went on for days; perhaps for many weeks, in a blind, instinctive search for light and outer air.

The flora and fauna of the caverns changed. He dragged himself through passages that were wholly lined with bristling, glowing thallophytes, some of which were tough and sharp as if fibered with iron. He came to tepid lakes whose waters were infested by long, agile, hydra-bodied creatures, divided into tapeworm segments, that rose to dispute his way but were powerless to harm his mouffa-covered limbs with their toothless, pulpy mouths.

For awhile, he seemed to be passing through a zone of unnatural warmth, due, no doubt, to the presence of hidden volcanic activity. There were hot geysers, and gulfs from which sultry vapors rose, filling the air with queer, metallic-smelling gases that seemed to burn corrosively in his nostrils and lungs. Some remnant of his former scientific knowledge caused him to recoil from such neighborhoods and retrace his footsteps into caverns free of these gases.

Fleeing from one of the mephitic-laden caves, he found himself in a mile-wide chamber, lined with fungi of uncommon exuberance, amid whose luminiferous growths he met with one of his most terrible adventures. A vast and semi-ophidian monster, white as the other life-forms he had met, and equally legless but owning a single, Cyclopean, phosphoric eye, leapt upon him from the unearthly vegetation and hurled him to the ground with the ram-like impact of its blunt, shapeless head. He lay half-stunned, while the monster began to ingest him in its enormous maw, starting with his feet. Seemingly the metal which he wore was no barrier to its appetite. The creature had swallowed him nearly to the hips, when he recovered his senses and realized his frightful predicament.

Smitten with hideous terror, howling and gibbering like a caveman, he lifted the metal rod, which his clutching fingers had somehow retained, and struck frantically at the awful head into whose mouth he was being drawn by inches. The blows made little or no impression on the great rubbery mass; and soon he was waist-deep in the monstrous maw. In his dire need, a trace of reasoning-power returned to him; and using the rod like a rapier he thrust it into the immense, glaring eye, burying it to his hand, and probably penetrating whatever rudimentary semblance of brain the animal possessed. A pale and egg-like fluid oozed from the broken eye, and the slobbering lips tightened intolerably upon Howard, almost crushing him in what proved to be the death-spasm. The white, swollen barrel-thick body tossed for many minutes; and during its convulsions, Howard was knocked insensible. When he came to again, the creature was lying comparatively still; and the sack-like mouth had begun to relax, so that he was able to extricate himself from the dreadful gorge.

The shock of this experience completed his mental demoralization and drove him even further into primitive brutehood. At times, his brain was almost a blank; and he knew nothing, remembered nothing but the blind horror of those infra-planetary caverns and the dumb instinct that still impelled him to seek escape.

Several times, as he continued his way through the thickets of fungi, he was forced to flee or hide from other monsters of the same type as the one that had so nearly ingested him. Then he entered a region of steep acclivities that took him ever upward. The air became chill and the caverns were seemingly void of vegetable or animal life. He wondered dully as to the reason of the growing cold; but his broken mind could suggest no explanation.

Before entering this realm, he had supplied himself with another fragment of luminiferous fungus to light his way. He was groping through a mountain-like wilderness of chasms and riven scarps and dolomites, when, at some distance above, he saw with inexpressible fright a glimmering as of two cold green eyes that moved among the crags. He had virtually forgotten the Oumnis and their lamps; but something—half intuition, half memory—warned him of direr peril than any he had hitherto met in the darkness.

He dropped his luminous torch and concealed himself behind one of the dolomitic formations. From his hiding-place, he saw the passing of two of the Immortals, clad in silvery mouffa, who descended the scarp and vanished in the craggy gulfs below. Whether or not they were hunting for him, he could not know; but when they had gone from sight, he resumed his climb, hurrying at breakneck speed and feeling that he must get as far away as possible from the bearers of those icy green lights.

The dolomites dwindled in size, and the steep chamber narrowed like the neck of a bottle and closed in upon him presently from all sides, till it was only a narrow, winding passage. The floor of the passage became fairly level. Anon, as he followed it, he was startled and blinded by a glare of light directly ahead—a light that was brilliant as pure sunshine. He cowered and stepped back, shielding his eyes with his hands till they became somewhat tempered to the glare. Then, stealthily, with a mingling of confused fears and dim, unworded hopes, he crept toward the light and came out in an endless metal hall, apparently deserted but filled as far as eye could see with the apparently sourceless brilliance.

The mouth of the rough natural passage from which he had emerged was fitted with a sort of valve, which had been left open, doubtless by the Immortals he had seen among the nether crags. The boat-shaped vehicle they had used was standing in the hall. This vehicle, and the hall itself, were familiar to him, and he began to recollect, in a partial way, the ordeals he had undergone among the Oumnis before his flight into outer darkness.
