Led to believe that his natural mother is a chimpanzee, a young boy knows only the savage ways of the great apes. Kept in a cage, he is systematically trained to become a savage killer by the fiendish Dr. Bracken. The target of Bracken’s rage is none other than the woman who spurned him-the orphan boy’s own mother!After fate causes him to be shipwrecked on the coast of Venezuela, the feral youngster, accompanied by his surrogate mother, Chicma the chimp, escapes into the jungle and discovers a strange land inhabited by prehistoric dinosaurs and primitive man-monsters. Transformed by contact with the beautiful Ramona, the teenaged beast-boy learns the ways of civilization and becomes Jan of the Jungle!Otis Adelbert Kline was a popular Argosy writer in the vein of Edgar Rice Burroughs. He specialized in planetary romances set on Mars and Venus, so it was inevitable that he would follow in Burroughs’ literary footsteps by creating a version of Tarzan of the Apes to call his own. Jan of the Jungle reappeared in the Argosy sequel, Jan in India, and was adapted as a 1935 Universal serial, Call of the Savage.Volume #28 in The Argosy Library.
