Next moment, Madden saw right beneath him a smack. The vessel was floating by, and the peak of its boom scraped the high iron wall of the dock. This boom had struck his platform.

Madden clutched impotently at the blank iron wall, then flung an arm for one of the supporting ropes and missed.

"Jump to me!" yelled Smith. The Englishman was still on the rope ladder, but had climbed down rapidly when he saw his mate in distress. The boom was tilting the platform straight up and down. The deck of the smack below promised to mash the American into a pulp. The fishermen were shouting. Leonard made a falling leap toward Caradoc's extended hand. He caught it in both his own. The Englishman's other hand gripped the rope rung. Unfortunately Madden's body flung out with a twisting motion, and he could feel Smith's arm grow tense in an effort to keep from being wrenched.

Madden was scrambling with his legs for a foothold on the ladder when the boom dragged past the platform and the whole thing swung back on the distressed boys. A flying end caught Madden in the side. The blow sickened him. He clung desperately to Caradoc's hand, his grip weakening, his senses swimming with the feeling of an awful void beneath him. The strength in his fingers gave way, and he felt a chill sensation before the coming downward plunge. But even in his twisted, straining position, the Englishman's long fingers did not loose Madden's wrist. A moment later, Leonard had lost consciousness completely, swung in midair, limp as a bag.

The American had a dim impression of being drawn to the top of the side wall, and the crew clustering about him. Someone splashed water in his face and the world cleared up before his eyes. The young fellow called Greer was whisking on the water, but when Madden opened his eyes, he set the bucket down and returned silently to his work.

"There, ye're bether now," grinned Hogan stooping over the wounded man. "That platform caught yez a little love lick in the slats—break any of 'em?"

Leonard reached across and felt his side. "How came the smack there?" he inquired weakly. "Why didn't I see it?"

"Ye was lookin' astern, an' th' vissil barely turned the bow of th' dock an' her boom kissed us all th' way down. I yilled at ye, so did Dashalong an' th' silent man. Thin I got so interested in l'arnin' he could say a worrd, I quit lookin' at you complately."

"I couldn't hear for the gulls—I'll be all right in a minute."

Leonard looked around and saw Caradoc massaging his twisted arm. He had an impulse to thank the Briton, but he changed it to, "I hope your arm isn't badly wrenched, Smith."
