A down-and-out new chum attacked by aborigines en route to the Gilbert River goldfield and left "not right in the head" is befriended by the supercargo of an Island trader in Port Denison (Bowen.) After he helps save his benefactor's life in a savage fight with natives in the Admiralty Islands, his health is restored by a stunning blow on the other side of his head, according to the theory that "like cures like" as propounded by the officiating German doctor.
