“Do you think you'll go up there?” asked North.

Orde shook his head.

“They're in a nice pickle,” he acknowledged; “but Nolan's in charge and will do his best. I think we may have troubles of our own right here at home.”

He slept that night at the booms. The water, contrary to all expectation, rose steadily. By morning it had crept so far up the piles that there began to be danger that it would overflow their tops. In that case, of course, the logs in the booms would also run out.

“Guess it's time we did a little work,” remarked Orde.

He set a crew of men to raising the height of the piling by tying logs firmly to the bolted timbers atop. This would take care of an extra two feet of water; a two feet beyond all previous records. Another crew stretched the fifteen inch manilla cables across the field of logs in order to segregate them into several units of mass, and so prevent them from piling up at the down-stream end of the enclosure. The pile-driver began to drop its hammer at spots of weakness. In spite of the accelerated current and the increased volume of the river, everything was soon shipshape and safe.

“We're all right now,” said Orde. “The only thing I'm a little uneasy about is those confounded temporary booms upstream. Still they're all right unless they get to piling up. Then we'll have to see what we can do to hold them. I think as soon as the driver is through down at the sorting end, she'd better drive a few clumps of piles to strengthen the swing when it is shut. Then if the logs pile down on us from above, we can hold them there.”

About two hours later the pile-driver moved up. The swing was opened; and the men began to drive clumps of piles in such a position as to strengthen the swing when the latter should be shut. It was a slow job. Each pile had to be taken from the raft at the stern of the scow, erected in the “carrier,” and pounded into place by the heavy hammer raised and let drop in the derrick at the bow.

Long before the task was finished, the logs in the temporary booms had begun to slide atop one another, to cross and tangle, until at last the river bed inside the booms was filled with a jam of formidable dimensions. From beneath it the water boiled in eddies. Orde, looking at it, roused himself to sudden activity.

“Get a move on,” he advised Captain Aspinwall of the driver. “If that jam breaks on us, we want to be ready; and if it don't break before you get this swing strengthened, maybe we can hold her where she is. There's no earthly doubt that those boom piles will never stand up when they get the full pressure of the freshet.”
