Excellent writing and attractive bookmaking distinguish this book by the author of Swamp Fox Brigade, which was intended for somewhat younger readers. This is the story of a voyage made in 1945, just as the war in Europe was ending. The thirteenth voyage, with a cargo of explosives and two green seamen, under draft age, make an uneasy, tense trip full of excitement. Rusty, who earnestly wants to be a seaman, works hard, makes good friends, and learns about ships, men, cargoes, the history of ship conditions, the union, race relations in a boiling sea, and some of the satisfactions of the job. To his chum, Salty, it looked like a hard row, and he had more trouble than Rusty, but he learned in spite of himself. Sharks, subs, storms, all keep the story rolling. At times the incidents seem more forced than in Swamp Fox Brigade, but the writing is good enough to hold it up.
