"Lost Island" by Ralph Henry Barbour and H. P. Holt is a seafaring adventure novel written in the early 20th century. It follows Brooklyn teenager Dave Hallard, a born sailor, who is stirred by tales of the South Seas and a mysterious wreck—the bark Hatteras—rumored to have carried a fortune in platinum. Drawn by the promise of adventure, he ships out, learns the hard realities of life at sea, and crosses paths with storms, derelicts, and distant islands. Expect classic nautical thrills—salvage gambles, shipboard rivalries, and hints of treasure—told as a coming‑of‑age voyage under the Southern Cross. The opening of the novel begins with Dave hearing an old mariner’s account of sighting the wreck of the Hatteras near the Fanning–Christmas Islands and, at home, learning from his father’s clippings that the lost ship once carried platinum. Fired by the sea’s lure, he quietly signs on to the steamer Pacific Queen, leaves a note for his family, and endures rough apprenticeship: a kind but gruff cook (Barnes), a hostile mate (Quick), seasickness, and hard work. Mid‑voyage the crew tries to tow a derelict, the Miriam; she founders, the dories are nearly sucked down in the whirlpool, and Dave helps spot and save a drowning sailor. After rounding Cape Horn, he decides to leave the ship at Auckland to escape the mate’s rancor, boards briefly with kind locals, then—strapped for options—signs onto the decrepit tramp Kingfisher for Australia, immediately regretting the choice as its engineer decries the failing machinery.
