At length, when it seemed that they were irretrievably lost in the solid abysmal murk, when their eyes had forgotten the very memory of sight, the darkness before them was pierced by a pinpoint of light. The light increased by slow, uncertain degrees, but for awhile they were doubtful as to its nature, not knowing whether they were approaching another vault of phosphorescence, or the actual outer daylight. However, they were thankful for its dim glimmering. The stream had become still swifter and rougher, with boulder-cloven rapids in which their descent was impetuous and dangerous. More than once the men were almost thrown against the dark and jagged masses that towered about them.
All at once the current slackened and the seething rapids died in a broad pool above which the arching of the lofty cavern-dome was now discernible. The light poured in a stream of pale radiance across this pool, from what was evidently the cavern’s mouth; and beyond the mouth a large sheet of sun-white water stretched away and was lost in the luminous distance.
All three men were suddenly conscious of a crushing, dragging fatigue—an overwhelming reaction from all the peril and hardship they had undergone. But the prospect of emergence from this underworld of mysterious horror prompted them to summon their remaining strength; with sodden limbs, they swam toward the cavern-mouth and floated through its black arch into the silver dazzle of a great lake.

The lake was probably the same body of water they had seen from afar on the previous day. Its aspect was ineffably weird and desolate. High cliffs with many buttresses and chimneys overhung the cavern from which they had emerged, and ran away on either side in gradually descending lines till they ceased in long flats of ooze and sand. There was no trace of vegetation anywhere—nothing but the swart stone of the cliffs, and the grey mud of the marshes, and the wan, dead waters. And at first the men thought that there was no life of any kind.
They swam along the cliff, looking for a place to land. The levels of ooze and sand were seemingly miles away; and their progress in the sluggish lake was excruciatingly slow and tedious. They felt as if the strange, lifeless waters had soaked them to the bone; and a deadly inertia dragged them down and drugged their very senses till everything became blurred in a monotone of faintness. They were all too exhausted to speak or even think. Dimly, despairingly, they plowed on toward the receding goal of the far-off shore.
Somehow, they were aware that a shadow had fallen upon them, breaking the diffused glare of the foggy sun. They were too weary to look up, or even speculate as to the origin of the shadow. Then they heard a harsh, jarring cry and a beating as of stiff, enormous wings, and something swooped down and hovered above them.
Turning their heads in the water, the three men saw an incredible sight. The thing that shadowed them was a mammoth bird-like creature with ribbed and leathern wings that were at least fifty feet from tip to tip. It suggested that prehistoric flying monster, the pterodactyl; and also it suggested a pelican, for beneath its seven-foot beak there hung a prodigious pouch.
Scarcely crediting their eyes, the swimmers stared at the hovering apparition. It glowered upon them with malevolent orbs of fire big as dinner-plates; and then, with horrible swiftness, it descended. Adams, who was nearest, felt the huge beak close upon him and lift him from the water; and before he could realize what was happening he found himself in the interior of the pouch. Deming was seized and deposited beside him a moment later; and Roverton, who had instinctively dived beneath the surface, was retrieved and drawn out by the questing beak as if he had been a flounder, and joined the other two.
Utterly stunned, they groped about in the noisome darkness of the pouch and were thrown prostrate in a heap as they felt the monster rise and soar heavenward. There were eel-like things that squirmed beneath them; and they breathed a medley of suffocating stenches. They could see nothing; but the gloom in which they lay was not absolute blackness, for the walls of the pouch were sufficiently permeable by light to create a blood-like dusk. The men could hear the loud beating of the leathern wings, could feel the rhythmic throb of their vibration; and while they were trying to habituate themselves to the unique situation, they had the sense of being borne onward in vertiginous flight at a great altitude.
Roverton was the first to speak.
“Of all the ineffable predicaments! Even a fiction-writer wouldn’t dare to imagine this. I suppose the creature has a nest somewhere and is carrying us home to provide food for its young or its mate.”
“Or,” suggested Adams, “having caught a supply of live meat, it’s going off somewhere to secure its vitamins.”
A faint laughter greeted the jest.
“Well,” put in Deming, “we’re getting a free ride, anyhow—for once we’re not having to walk, run or swim. ”
Time passed in a doubtful, confused way. The beating of the wings had died to a swish of rushing air as about the unflapping level of flight of some giant vulture or bird of prey. Still there was the sense of prodigious speed, of horizon on horizon left behind, of plains and waters and mountains slipping away beneath in a swift recession.
The men grew sick and dizzy with the noxious air of their prison, they fell into periods of semi-consciousness from which they revived with a start. In the novel horror of their position, they almost lost the feeling of identity. It was as if they were part of some monstrous dream or hallucination.
After an undetermined lapse of time, they felt a slackening of the headlong flight and then heard once more the thunderous flap of those huge wings as the bird sank groundward. It seemed to descend from an alp-surpassing height, with tremendous velocity.
Now the descent was arrested with abrupt ease, like the stopping of an elevator. A sudden glimmering of light in the interior of the pouch, and Roverton and his companions were aware that the creature had opened its bill as if to seize something. Then, with a raucous, deafening cry, it began to thresh about as in some stupendous convulsion, and the men were thrown violently from side to side in the tossing pouch. It was impossible to imagine what had happened—the whole occurrence was supremely mysterious and terrifying. Adams and Deming were knocked almost senseless by the shaking they received; and Roverton alone was able to retain anything like full cognizance. He realized that the bird was engaged in some sort of struggle or combat. After a brief interval its heavings became less tumultuous and powerful; and at last, with one hoarse, diabolic shriek, it appeared to collapse and lay still except for an occasional shuddering that shook body and neck and was communicated to the pouch. These shudderings diminished in force and frequency. The bird was now lying on its side, and the light entered the pouch directly through its wide-open beak.
Making sure that his companions had recovered their senses, Roverton crawled toward the light. The others followed in turn. Wriggling out through the slimy mouth, from which a frothy blood-like fluid was dripping, Roverton stood up dizzily and looked around.
The scene upon which he had emerged was wilder and madder than the grotesqueries of fever-delirium. For an instant he thought that the things about him were products of hallucination, were born of his overwrought nerves and brain. The flying monster was stretched on the ground and was wrapped from head to tail in the coils of something which Roverton could only designate to himself as a vegetable anaconda. The coils were pale-green with irregular brown and purplish mottlings and were manifestly hundreds of feet in length. They terminated in three heads covered with mouths like the suckers of an octopus. The coils had encircled the bird many times, and were evidently possessed of enormous constrictive power, for they had tightened upon their prey so that the body bulged between them in loathsome knots and protuberances. They were visibly rooted in a black, viscid-looking soil and were swollen at their base like the bole of some ancient tree. The three heads had applied themselves to the back of their prostrate victim and were obviously drawing sustenance from it with their myriad suckers.
