He promised and left her. Then, cautiously, step by step, he made his way along the ledge in the other direction from that where he had found the senseless girl.

To the very end of the ledge he penetrated, but found no hope. Nothing was to be seen through the mists save the mad foam-rush of the waters that leaped and bounded like white-maned horses in a race of death.

Bold as the man was, he dared not look for long. Dizziness threatened to overwhelm him with sickening lure, its invitation to the plunge.

So, realizing that nothing was to be gained by staying there, he drew back and once more sought Beatrice.

"Any way out?" she asked him, anxiously, her voice sounding clear and pure through the tumult of the rushing waters.

He shook his head, despairingly. And silence fell again, and each sat thinking long, long thoughts, and dawn came creeping grayly through the spume-drive of the giant falls.

More than an hour must have pa.s.sed before Stern noted a strange phenomenon--an hour in which they had said few words--an hour in which both had abandoned hopes of life--and in which, she in her own way, he in his, they had reconciled themselves to the inevitable.

But at last, "What's that?" exclaimed the man; for now a different tone resounded in the cataract, a louder, angrier note, as though the plunge of waters at the bottom had in some strange, mysterious way drawn nearer. "What's that?" he asked again.

Below there somewhere by the tenebrous light of morning he could see--or thought that he could see--a green, dim, vaguely tossing drive of waters that now vanished in the whirling mists, now showed again and now again grew hidden.

Out to the edge of the rocky shelf he crept once more. Yes, for a certainty, now he could make out the seething plunge of the waters as they roared into the foam-lashed flood below.

But how could this be? Stern's wonder sought to grasp a.n.a.lysis of the strange phenomenon.

"If it's true that the water at the bottom's rising," thought he, "then there must either be some kind of tide in that body of water or else the cavity itself must be filling up. In either case, what if the process continues?"

And instantly a new fear smote him--a fear wherein lay buried like a fly in amber a hope for life, the only hope that had yet come to him since his awakening there in that trap sealed round by sluicing maelstroms.

He watched a few moments longer, then with a fresh resolve, desperate yet joyful in its strength, once more sought the girl.

"Beta," said he, "how brave are you?"

"How brave? Why, dear?"

He paused a moment, then replied: "Because, if what I believe is true, in a few minutes you and I have got to make a fight for life--a harder fight than any we've made yet--a fight that may last for hours and may, after all, end only in death. A battle royal! Are you strong for it? Are you brave?"

"Try me!" she answered, and their eyes met, and he knew the truth, that come what might of life or death, of loss or gain, defeat or victory, this woman was to be his mate and equal to the end.

"Listen, then!" he commanded. "This is our last, our only chance. And if it fails--"

CHAPTER XIII

ON THE CREST OF THE MAELSTROM

Stern's observation of the rising flood proved correct. By whatever theory it might or might not be explained, the fact was positive that now the water there below them was rising fast, and that inside of half an hour at the outside the torrent would engulf their ledge.

It seemed as though there must be some vast, rhythmic ebb and flux in the unsounded abysses that yawned beneath them, some incalculable regurgitation of the sea, which periodically spewed forth a part, at least, of the enormous torrent that for hours poured into that t.i.tanic gulf.

And it was upon this flux, stormy and wild and full of seething whirlpools, that Allan Stern and the girl now built their only possible hope of salvation and of life.

"Come, we must be at work!" he told her, as together they peered over the edge and now beheld the weltering flood creeping up, up along the thunderous plunge of the waterfall till it was within no more than a hundred feet of their shelter.

As the depth of the fall decreased the spray-drive lessened, and now, with the full coming of day, some reflection of the golden morning sky crept through the spray. Yet neither to right nor left could they see sh.o.r.e or anything save that long, swift, sliding wall of brine, foam-tossed and terrible.

"To work!" said he again. "If we're going to save ourselves out of this inferno we've got to make some kind of preparation. We can't just swim and trust to luck. We shall have to malice float of some sort or other, I think."

"Yes, but what with?" asked she.

"With what remains of the yawl!"

And even as he spoke he led the way to the crevice where the splintered boards and the torn sail had been wedged fast.

"A slim hope, I know," he admitted, "but it's all we've got now."

Driven home as the wreckage was by the terrific impact of the blow, Stern had a man's work cut out for him to get it clear; but his was as the strength of ten, and before half an hour had pa.s.sed he had, with the girl's help, freed all the planks and laid them out along the rock-shelf, the most sheltered spot of the ledge.

Another hour later the planks had been lashed into a rough sort of float with what cordage remained and with platted strips of the mat sail.

"It's not half big enough to hold us up altogether," judged the man, "but if we merely use it to keep our heads out of water it will serve, and it's got the merit of being unsinkable, anyhow. G.o.d knows how long we may have to be in the water, little girl. But whatever comes we've got to face it. There's no other chance at all!"

They waited now calmly, with the resignation of those who have no alternative to hardship. And steadily the flood mounted up, up, toward the ledge, and now the seethe was very near. Now already the leaping froth of the plunge was dashing up against their rock. In a few moments the shelter would be submerged.

He put his lips close to her ear, for now his voice could not carry.

"Let's jump for it!" he cried. "If we wait till the flood reaches us here we'll be crushed against the rock. Come on, Beatrice, we've got to plunge!"

She answered with her eyes; he knew the girl was ready. To him he drew her and their kiss was one that spoke eternal farewell. But of this thought no word pa.s.sed their lips.

"_Come!_" bade the man once more.

How they leaped into that vortex of mad waters, how they vanished in that thunderous welter, rose, sank, fought, strangled, rose again and caught the air, and once more were whirled down and buried in that crushing avalanche; how they clung to the lashed planks and with these spiraled in mad sarabands among the whirlpools and green eddies; how they were flung out into smoother water, blinded and deafened, yet with still the spark of life and consciousness within them, and how they let the frail raft bear them, fainting and dazed, all their senses concentrated just on gripping this support--all this they never could have told.

Stern knew at last, with something of clarity, that he was floating easily along an oily current which ran, undulating, beneath a slate-gray mist; he realized that with one hand he was grasping the planks, with the other arm upbearing the girl.

Pale and with closed eyes, she lay there in the hollow of his arm, her face free from water, her long hair floating out upon the tide.

He saw her lids twitch and knew she lived. Yet even as he thanked G.o.d and took a firmer hold on her, consciousness lapsed again, and with it all realization of time or of events.

Yet though the moments--or were they hours?--which followed left no impress on his brain, some intelligence must have directed Stern. For when once more he knew, he found the mist and fog all gone; he saw a golden sun that weltered all across the heaving flood in a brave splendor; and, off to northward, a wooded line of hills, blue in the distance, yet beautiful with their promise of salvation.

Stern understood, then, what must have happened. He saw that the upfilling of the abyss, whatever might have caused it, had flung them forth; he perceived that the temporary flood which had taken place before once more another terrific down-draft should pour into the gaping chasm, had cast them out, floated by their raft of planks, even as match-straws might be flung and floated on the outburst of a geyser.

He understood; he knew that, fortune favoring, life still beckoned there ahead.

And in his heart resolve leaped up.

"Life! Life!" he cried. "Oh, Beatrice, look! See! There's land ahead, there--_land!_"

But the girl, still circled by his arm, lay senseless. Allan knew he could make no progress in that manner. So by dint of great labor, he managed to draw her somewhat onto the float and there to lash her with a loose end of cordage in such wise that she could breathe with no danger of drowning.

Himself he summoned all his forces, and now began to swim through the smooth tides, which, warm with some grateful heat, vastly unlike the usual ocean chill, stretched lazily rolling away and away to that far off sh.o.r.e.
