Footprints in the Forest by Edward Ellis

Classic adventure novel. According to Wikipedia: Edward Sylvester Ellis (April 11, 1840 – June 20, 1916) was an American author who was born in Ohio and died at Cliff Island, Maine. Ellis was a teacher, school administrator, and journalist, but his most notable work was that that he performed as author of hundreds of dime novels that he produced under his name and a number of noms de plume. Notable works by Ellis include The Huge Hunter, or the Steam Man of the Prairies and Seth Jones, or the Captives of the Frontier. Internationally, Edward S. Ellis is probably best known for his Deerhunter novels widely read by young boys up to the 1950s (together with works by James Fenimore Cooper and Karl May). In the mid-1880s, after a fiction-writing career of some thirty years, Ellis eventually turned his pen to more serious works of biography, history, and persuasive writing.
