"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 shore. 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.
