Here is the entry for Horace Kephart in my book The Illustrated Encyclopaedia of Walking & Backpacking, 1991 (now out of print).
Kephart, Horace (1862-1932). American librarian and author of The Book of of Camping & Woodcraft, 2nd ed., 1909 which was later revised and expanded as Camping & Woodcraft; a Handbook for Vacation Campers and for Travelers in the Wilderness, 1917. These comprehensive manuals contain extremely detailed instructions on all aspects of surviving in the American wilderness, and cover such subjects as pack-carrying, fire-making and camp cooking, cabin-building, axemanship, navigation, path-finding, and trail-blazing etc. They were issued in this country, where conditions are entirely different, and some of the more popular British outdoor writers continued to extol is methods until the nineteen fifties. Kephart is rightly acknowledged as an early and influentail writer about wilderness travel and survival, with a sound knowledge of his subject, but his influence in Britain has not been beneficial.
