The Madman and the Pirate

According to Wikipedia: "R. M. Ballantyne (24 April 1825 – 8 February 1894) was a Scottish juvenile fiction writer... For some time he was employed by Messrs Constable, the publishers, but in 1856 he gave up business for the profession of literature, and began the series of adventure stories for the young with which his name is popularly associated. The Young Fur-Traders (1856), The Coral Island (1857), The World of Ice (1859), Ungava: a Tale of Eskimo Land (1857), The Dog Crusoe (1860), The Lighthouse (1865), Deep Down (1868), The Pirate City (1874), Erling the Bold (1869), The Settler and the Savage (1877), and other books, to the number of upwards of a hundred, followed in regular succession, his rule being in every case to write as far as possible from personal knowledge of the scenes he described."
