The first rollway broke badly.

A thick-butted log slanted and met the others head-on as they thundered down the bank, tossing them high in the air whence they fell splashing into the river, or crashed backward among the tumbling logs, upending, and hurling them about like jack-straws.

The air was filled with the heavy rumble of rolling logs as other rollways tore loose at the swift blows of the axes, where, at the crack of toggle-pins, men leaped from in front of the rolling, crushing death; and the surface of the river became black with bucking, pitching logs which shot to the opposite bank.

Coincident with the snapping of the first toggle-pin, the branches of a gigantic, storm-blasted pine, whose earth-laded butt dragged heavily along the bottom of the river, became firmly entangled in the low-hanging limbs of a sweeper, and swung sluggishly across the current.

Against this obstruction crashed the leaping, upending logs of the wrecked rollway. Other logs swept in and wedged, forcing the heavy butt and the riven trunk of the huge tree firmly against the rocks at the head of the rapid.

Rollway after rollway tore loose and the released logs, swept downward by the resistless push of the current, climbed one upon another and lodged. Higher and higher the jam towered, the interlocking logs piling in hopeless tangle.

Moncrossen was beside himself. Up and down the bank he rushed, bellowing orders and hurling curses at the men who, gripping their peaveys, swarmed over the heaving jam like flies.

The bateau men, forty of them, lifted the heavy boat bodily, and working it out to the very forefront of the jam, lowered it into the water, while other men made the heavy cable fast to the trunk of a tree. Close under the towering pile the bateau was snubbed with a short, light line, and the men clambered shoreward, leaving only Moncrossen, Stromberg, Fallon, and one other to search for the key-log.

It was a comparatively simple jam, the key to which was instantly apparent to the experienced rivermen, in two large logs wedged in the form of an inverted V. The quick twist of a peavey inserted at the vertex of the angle, and the drive should move.

Fallon and Stromberg, past masters both of the drive made ready while the other stood by to cast off the light line and allow the bateau to swing free on the main cable.
