The Huge Hunter; Or, The Steam Man of the Prairies

The Steam Man of the Prairies by Edward S. Ellis was the first U.S. science fiction dime novel and archetype of the Frank Reade series. The first novel starts when Ethan Hopkins and Mickey McSquizzle—a "Yankee" and an "Irishman"—encounter a colossal, steam-powered man in the American prairies. This steam-man was constructed by Johnny Brainerd, a teenage boy, who uses the steam-man to carry him in a carriage on various adventures.
