_The History of Prince Lee Boo_ (1789) is an early example of this interest in coloured races. Children’s books of the early nineteenth century include many stories of the Slave Trade and adventures of Negroes. Some of the most popular were _The Adventures of Congo_ (1823); Mary Ann Hedge’s _Samboe; or, the African Boy_ (1823); _Radama; or, the Enlightened African_ (1824).
