As Lane stood on the ledge, knee-deep in the water, with the certainty that he had a perfect photograph of the field of tumbling waters below in his mind's eye, a strange voice seemed to whisper in his ear. _"This is your great trial!"_ Without further hesitation he shoved the boat off the ledge. Round and round the back eddy he floated. At the outlet on the down-stream side, where the gleaming line of foam marked the escape of water into the on-rushing current, he whirled his boat, stern ahead. Down he shot with a plunge and then up with a rise. Racing on over the uneven swells he felt the hissing spray, and the malignant tips of the waves that broke their fury on the boat and expended it in a shower of stinging drops. The wind cut his face. He rode a sea of foam, then turgid rolling mounds of water that heaved him up and up, and down long planes that laughed with hollow boom, then into channels of smooth current, where the torrent wreathed the black stones in yellowish white. Lane saw the golden sun, the blue sky, the fleecy clouds, the red and purple of the colored hills; and felt his chest expand with the mounting glory of great effort. The muscles of his back and arms, strengthened by the long toil with his heavy axe, rippled and swelled and burned, and stretched like rubber cords, and strung tight like steel bands. The boat was a toy. He rodes the waves, and threaded a labyrinth of ugly stones, and shot an unobstructed channel, and evaded a menacing drift. The current carried him irresistibly onward. When his keen eye caught danger ahead he sunk the oars deep and pulled back. A powerful stroke made the boat pause, another turned her bow to the right or left, then the swift water hitting her obliquely sheered her in the safe direction. So Lane kept afloat through the spray that smelled fresh and dank, through the crash and surge and roar and boom, through the boiling caldron. The descent quickened. On! On! he was borne with increasing velocity. The yellow demons rose in fury. Boo--oom! Boo--oom! The old river god voiced his remorseless roar. The shrill screaming shriek of splitting water on sharp stones cut into the boom. On! On! Into the yellow mist that might have been smoke from hell streaked the boat, out upon a curving billow, then down! down! upon an upheaving curl of frothy water. The river, like a huge yellow mound, hurled its mass at Lane. All was fog and steam and whistling spray and rumble. At length the boat swept out into the open with a long plunge over the last bit of roughened water. Here the current set in a curve to the left, running off the rocky embankment into the natural channel of the river. The dam was now only a couple of hundred yards distant. The water was smooth and the drift had settled to a slow, ponderous, sliding movement.
