He departed up river on a tour of inspection from which he returned almost immediately.
“Hurry up! Hurry up!” he cried. “She can't last much longer!”
Indeed even to the men on the pile-driver, evidences of the pressure sustained by the slender boom piles were not wanting. Above the steady gurgle of the water and the intermittent puffing and other noises of the work, they could hear a creaking and groaning of timbers full of portent to those who could read the signs.
The driver's crew laboured desperately, hoisting the piles into the carriage, tripping the heavy hammer, sending it aloft again, binding feverishly the clumps of piles together by means of cables. Each man worked with an eye over his shoulder, fearful of the power that menaced him.
Two of the clumps had been placed and bound; a third was nearly finished, when suddenly, with a crack and a roar the upper booms gave way, projecting their logs upon the opening and the driver.
The half dozen members of the crew, caught utterly unaware in spite of the half warning they had been receiving for an hour past, were scattered by the winds of a panic. Two or three flung themselves on their faces; several ran from one end of the scow to the other; one leaped into the river! Imminent destruction seemed upon them.
Tom North, at the winch that operated the arm of the swing, however, retained his presence of mind. At the first sag outward of the boom piles he set in operation the machinery that closed the gate. Clumsy and slow as was his mechanism, he nevertheless succeeded in getting the long arm started. The logs, rushing in back of it, hurried it shut. Immediately they jammed again, and heaped up in a formidable tangle behind the barrier. Tom North, his little black pipe between his teeth, stood calm, the lever of his winch in his hand. A short three feet from the spot on which he stood, the first saw log of the many that might have overwhelmed him thrust forward its ugly head. The wash of the water lifted the huge pile-driver bodily and deposited it with a crash half on the bank and half in the water.
Instantly after the first break Orde had commenced running out over the booms from the shore.
“Good boy, Tom!” he shot at North as he passed.
Across the breast of the jam he hurried, and to the other bank where the pile-driver lay. The crew had recovered from their panic, and were ashore gazing curiously underneath the scow. Captain Aspinwall examined the supports of the derrick on deck.
