It is possible to document almost endlessly the ways in which the labels "Shoshone," "Digger," and "Snake" were applied in turn or at the same time to Shoshone-Comanche and Mono-Bannock speakers alike. Since political or social significance has frequently been attributed to Indians' names--both those bestowed by the whites and those by which the several sectors of the Shoshone population referred to each other--we will discuss this nomenclature in the context of each section of the following report. II. THE EASTERN SHOSHONE It is necessary to preface all discussions of Shoshone Indians with a clarification of what is implied by the names attached to Shoshone subgroups. The commonly used appellation "Wind River Shoshone" implies no more than reservation membership. Thus, we also have "Owyhee Shoshone" and "Fort Hall Shoshone" (and Bannock). Wind River residents of admitted descent from other groups are also referred to as "Wind River people," if they are on the agency rolls. They were, of course, not known by this name or a native equivalent in the pre-reservation period. The names, "Eastern Shoshones" and "Eastern Snakes," by which the Shoshone of Wyoming are also known in anthropology, were first consistently applied by government officials during the 1850's and 1860's (cf. Lander, 1860, p. 131; Head, 1868, p. 179; Mann, 1869, p. 616). Lander also referred to the Eastern Shoshone as the "Wash-i-kee band of the Snake Indians" (Lander, 1859, p. 66). This term came into common use after Chief Washakie rose to prominence in the eyes of the whites. Previous to this period the Eastern Shoshone were called Snakes and Shoshones (or variations thereof), indiscriminately. As has been mentioned, the only firm distinction was made according to whether or not the Indians in question owned horses and hunted buffalo. Although Lewis and Clark never visited the Wyoming lands, the tribal lists which they compiled at Fort Mandan before pushing west mention a group, said by Clark to be "Snake," called the "Cas-ta-ha-na" or "Gens de Vache" (Lewis and Clark, 1904-06, 6:102). They were said to number 500 lodges having a population of about 5,000 people. The Shoshone identity of this people is somewhat obscured by Clark's report of an affinity between their language and that of the Minitaree, but, on the other hand, they were said to "rove on a S. E. fork of the Yellow Rock River called Big Horn, and the heads of the Loup" (ibid.). The "Cas-ta-ha-na" are mentioned also during the return trip of the expedition. Lewis and Clark noted of the Big Horn River: "It is inhabited by a great number of roving Indians of the Crow Nation, the paunch Nation (a band of Crows) and the Castahanas (a band of Snake In.)." The editor of the journals, Reuben Thwaites, identifies the latter as "Comanche." (Ibid., 5:297.)
