Popular novel, first published early in the twentieth century. According to Wikipedia: "Herbert Strang was the pseudonym of two English authors, George Herbert Ely (1866–1958) and Charles James L'Estrange (1867–1947). They specialized in writing adventure stories for boys. Both men were staff members of Oxford University Press, which published their books, giving them a patina of social status and approval for the parents of their intended audience. Their work showed a broad general debt to that of Jules Verne; Round the World in Seven Days was one of their most popular books. Ely and L'Estrange have been classified as "popular writers of imperial fiction" and "successors of G. A. Henty.”
