For a moment he could not answer. She, sensing some trouble, peered closely at him.

"What is it, Allan?" cried she, her woman's intuition telling her of trouble. "Tell me--is anything wrong?"

"Listen, dearest!"

"Yes, what?"

"We're in some kind of--of--"

"What? Danger?"

"Well, it may be. I don't know yet. But there's something wrong. You see--"

"Oh, Allan!" she exclaimed, and started up. "Why didn't you waken me before? What is it? What can I do to help?"

"I think there's rough water ahead, dear," the engineer answered, trying to steady his voice, which shook a trifle in spite of him. "At any rate, it sounds like a waterfall of some kind or other; and see, there's a line, a drift of vapor rising over there. We're being carried toward it on a strong current."

Anxiously she peered, now full awake. Then she turned to Allan.

"Can't we sail away?"

"Not enough wind. We might possibly row out of the current, and--and perhaps--"

"Give me one of the sweeps quick, quick!"

He put the sweeps out. No sooner had he braced himself against a rib of the yawl and thrown his muscles against the heavy bar than she, too, was pulling hard.

"Not too strong at first, dear," he cautioned. "Don't use up all your strength in the first few minutes. We may have a long fight for it!"

"I'm in it with you--till the end--whichever way it ends," she answered; and in the moonlight he saw the untrammeled swing and play of her magnificent body.

The yawl came round slowly till it was crosswise to the current, headed toward the mainland sh.o.r.e. Now it began to make a little headway. But the breeze slightly impeded it.

Stern whipped out his knife and slashed the sheets of platted rush.

The sail crumpled, crackled and slid down; and now under a bare pole the boat cradled slowly ahead transversely across the foam-streaked current that ran swiftly soughing toward the dim vapor-swirls away to the northeast.

No word was spoken now. Both Beatrice and Stern lay to the sweeps; both braced themselves and put the full force of back and arms into each long, powerful stroke. Yet Stern could see that, at the rate of progress they were making over that black and oily swirl, they could not gain ten feet while the current was carrying them a thousand.

In his heart he knew the futility of the fight, yet still he fought.

Still Beatrice fought for life, too, there by his side. Human instinct, the will to live, drove them on, on, where both understood there was no hope.

For now already the current had quickened still more. The breeze had sprung up from the opposite direction; Stern knew the boiling rush of waters had already reached a speed greater than that of the wind itself. No longer the stars trembled, reflected, in the waters. All ugly, frothing, broken, the swift current foamed and leaped, in long, horrible gulfs and crests of sickening velocity.

And whirlpools now began to form. The yawl was twisted like a straw, wrenched, hurled, flung about with sickening violence.

"Row! _Row!_" Stern cried none the less. And his muscles bunched and hardened with the labor; his veins stood out, and sweat dropped from his brow, ran into his eyes, and all but blinded him.

The girl, too, was laboring with all her might. Stern heard her breath, gasping and quick, above the roar and swash of the mad waters.

And all at once revulsion seized him--rage, and a kind of mad exultation, a defiance of it all.

He dropped the sweep and sprang to her.

"Beta!" he shouted, louder than the droning tumult. "No use! No use at all! Here--come to me!"

He drew the sweep inboard and flung it in the bottom of the yawl.

Already the vapors of the cataract ahead were drifting over them and driving in their faces. A vibrant booming shuddered through the dark air, where now even the moon's faint light was all extinguished by the whirling mists.

Heaven and sea shook with the terrible concussion of falling waters.

Though Stern had shouted, yet the girl could not have heard him now.

In the gloom he peered at her; he took her in his arms. Her face was pale, but very calm. She showed no more fear than the man; each seemed inspired with some strange exultant thought of death, there with the other.

He drew her to his breast and covered her face; he knelt with her among the heaped-up furs, and then, as the yawl plunged more violently still, they sank down in the poor shelter of the cabin and waited.

His arms were about her; her face was buried on his breast. He smoothed her hair; his lips pressed her forehead.

"Good-by!" he whispered, though she could not hear.

They seemed now to hover on the very brink.

A long, racing sluicelike incline of black waters, streaked with swirls of white, appeared before them. The boat plunged and whirled, dipped, righted, and sped on.

Behind, a huge, rushing, wall-like ma.s.s of lathering, leaping surges.

In front, a vast nothingness, a black, unfathomable void, up through which gushed in clouds the mighty jets of vapor.

Came a lurch, a swift plunge.

The boat hung suspended a moment.

Stern saw what seemed a long, clear, greenish slant of water. Deafened and dazed by the infernal pandemonium of noise, he bowed his head on hers, and his arms tightened.

Suddenly everything dropped away. The universe crashed and bellowed.

Stern felt a heavy dash of brine--cold, strangling, irresistible.

All grew black.

"_Death!_" thought he, and knew no more.
