When he reached the blast lamp, which was raised on a tall tripod, Vane stood with his back to the pulsating blaze while he grasped the details of a somewhat impressive scene. A little up-stream of him the river leaped out of the darkness, breaking into foaming waves, and a wall of dripping firs flung back the roar it made, the first rows of serried trunks standing out hard and sharp in the fierce white light. Nearer where he stood, a projecting spur of rock narrowed in the river, which boiled tumultuously against its foot, while about half-way across the top of a giant boulder rose above the flood.
Vane could only just see it, because a mass of driftwood, which was momentarily growing, stretched from bank to bank. A big log, drifting down sideways, had brought up upon the boulder and once fixed had seized and held fast each succeeding trunk. Some had been driven partly out upon those that had preceded them; some had been drawn beneath the latter, and catching the bottom had jambed. Then the rest had been wedged by the current into the gathering mass; trunks, branches, and brushwood all finding a place. When the stream is strong, a jamb, as it is called, usually extends downwards, as well as rises, as the water it pens back increases in depth, until it forms a solid barrier from surface to bed. If it occurs during a log-drive, the river is choked with lumber. Bent figures were at work with axes at the shoreward end of the mass; others had crawled out along the logs, in search of another point where they could advantageously be attacked; but Vane, watching them with practised eyes, decided that they were largely throwing their toil away. Next, he glanced down-stream; but powerful as the light was, it did not pierce far into the darkness and the rain, and the mad white rush of the rapid vanished abruptly into the surrounding gloom. Then he caught the clink of a hammer on a drill, and seeing Salter not far away strode towards him.
“How are you getting to work?” he asked.
Salter pointed to the foot of the rock they stood upon. “I reckoned if we could put a shot in yonder, we might cut out stone enough to clear the butts of the larger logs that are keying up the jamb.”
“You’re wasting time—starting at the wrong place.”
“It’s possible, but what am I to do? I’d sooner split that boulder or chop down to the king log there, but the boys can’t get across.”
“I think I could,” Vane answered. “I’ll try, if it’s necessary.”
Salter expostulated, “I want to point out that you’re the boss director of this company. I don’t know what you’re making out of it, but you can hire men to do the kind of work you think of undertaking for three dollars a day.”
“We’ll let the boys try it, if they’re willing.” Vane raised his voice. “Are any of you open to earn twenty dollars? I’ll pay that to the man who’ll put a stick of giant-powder in yonder boulder, and another twenty to whoever can find the king log and chop it through.”
Three or four of them crept cautiously along the driftwood bridge. It heaved and worked beneath them; the foam sluiced across it, and the stream forced the thinner tops of shattered trees above the barrier. It was obvious that the men were risking life and limb, and there was a cry from the rest when one of them went down and momentarily disappeared. He scrambled to his feet again, but those behind him stopped, bracing themselves against the stream, knee-deep in rushing froth. Most of them had followed rough and dangerous occupation in the bush; but they were not professional river-Jacks trained to high proficiency in log-driving, and one turning shouted to the watchers on the bank.
