Sequel to Half Deck -- autobiographical account of a voyage on the half deck of a British tramp steamer, the Monarch, under Capt. McFarlane, from the Firth of Clyde to Africa, across the Atlantic to the Barbadoes, New Orleans, and back. War was declared while they were in Africa, and the ship is pursued by a submarine, and blown up. Pranks and adventures of four cadets -- lots of excitement. A chance for a double sale, as it would appeal to men liking sea stories, and to teen age boys.
