CHEYENNE. This Algonkin tribe of the Plains, in Minne sota in the 57th century, drifted gradually westward through South Dakota to Wyoming and Colorado, and is now on reserva tions in Montana and Oklahoma. Their speech is much closer than either Blackfoot or Arapaho to the central Algonkin dialects, so that their divergence from the main body of the family is evi dently relatively late. Since about 185o the Sutaio, speaking a Cheyenne dialect, have been part of the tribe, though in 1804 they were still separate. The Cheyenne took a leading part in the Custer massacre of 1876. They were a typical Plains tribe— brave, warlike, non-agricultural, roving after the buffalo or for adventure ; and they show the physical type at its best, being perhaps the tallest tribe in the area. The tribal fetish was a set of four sacred arrows. In 1922 the population was 3,20o.
