Extermination of the American Bison

The Extermination of the American Bison is a book by William Temple Hornaday first published in 1889 by the Government Printing Office. It was reprinted from a report Hornaday wrote for the Smithsonian Institution in the years 1886–87.
Extermination contains an exhaustive account of bison ecology and the story of the near-entire destruction of the bison population in the United States. The book argues for the consequent necessity of protecting the small number of bison then in Yellowstone National Park.
