"Gordon's men are camped just above," he told them. "But we must get through without waking them. No talking, now, until we're safe."
Silently the crew resumed their tow-lines, fitting them to their aching shoulders; gingerly the boats were edged out into the current.
It was fortunate that the place was noisy, and that the voice of the river and the periodic bombardment from the glaciers drowned the rattle of loose stones dislodged by their footsteps. But it was a trying half-hour that followed. Dan did not breathe easily until his party had crossed the bar and were safely out upon the placid waters of the lake, with the last stage of the journey ahead of them.
About mid-forenoon of the following day Curtis Gordon halted his party at the lower end of the rapids and went on alone. To his right lay the cataract and along the steep slope against which it chafed wound a faint footpath scarcely wide enough in places for a man to pass. This trail dipped in and out, wound back and forth around frowning promontories. It dodged through alder thickets or spanned slides of loose rock, until, three miles above, it emerged into the more open country back of the parent range. It had been worn by the feet of wild animals and it followed closely the right-of-way of the S. R. & N. To the left the hills rose swiftly in great leaps to the sky; to the right, so close that a false step meant disaster, roared the cataract, muddy and foam-flecked.
As Gordon neared the first bluff he heard, above the clamor of the flood, a faint metallic "tap-tap-tap," as of hammer and drill, and, drawing closer, he saw Dan Appleton perched upon a rock which commanded a view in both directions. Just around the shoulder, in a tiny gulch, or gutter from the slopes above, were pitched several tents, from one of which curled the smoke of a cook-stove. Close at hand were moored four battered poling-boats.
"Look out!" Appleton shouted from on high.
Gordon flushed angrily and kept on, scanning the surroundings with practised eye.
"Hey, you!" Dan called, for a second time. "Keep back! We're going to shoot."
Still heedless of the warning, Gordon held stubbornly to his stride. He noted the heads of several men projecting from behind boulders, and his anger rose. How dared this whipper-snapper shout at him! He felt inclined to toss the insolent young scoundrel into the rapids. Then suddenly his resentment gave place to a totally different emotion. The slanting bank midway between him and Appleton lifted itself bodily in a chocolate-colored upheaval, and the roar of a dynamite blast rolled out across the river. It was but a feeble echo of the majestic reverberations from the glacier across the lake, but it was impressive enough to send Curtis Gordon scurrying to a place of safety. He wheeled in his tracks, doubling himself over, and his long legs began to thresh wildly. Reaching the shelter of a rock crevice, he hurled himself into it, while over his place of refuge descended a shower of dirt and rocks and debris. When the rain of missiles had subsided he stepped forth, his face white with fury, his big hands twitching. His voice was hoarse as he shouted his protest.
Appleton scrambled carefully down from his perch in the warm sunshine and approached with insolent leisure.
