The Mentor: Game Animals of America, Vol. 4, Num. 13, Serial No. 113, August 15, 1916

An illustrated survey by a naturalist recounts the dramatic decline of North American big-game species, tracing causes of wasteful slaughter and noting surviving populations and the limited opportunities for hunting. The text describes efforts to save species through governmental herds, national ranges, and zoo-sponsored programs, urges appreciation of wildlife beyond killing, and recommends photography and study as higher forms of sport. It treats particular species — bison, prong-horn antelope, elk, moose, sheep, goat, caribou, and bears — outlining their status, vulnerabilities, and the need for sanctuaries and intelligent preservation policies.
