_c._ _Shyennes._--Between the head-waters of the Yellow-stone River and the River Platte. Conterminous with the Upsaroka, Pawnees, and probably the northern Shoshonis. As such, isolated from the other Algonkins. _d._ _Blackfoot Algonkins._--Head-waters of the south branch of the Saskatchewan, and extended as far west as the Rocky Mountains, by which they are divided from the Kútanis. Bounded on the north by the Athabaskans, the south by the Upsarokas (Sioux), the east by the Ahnenin and Crees. The Blackfoots have been but recently recognised as Algonkin. The numerous details of this great division prevent anything beyond the doubtful points of the classification being noticed. These apply to three members of it, the Bethuck, the Shyennes, and the Blackfoots. 1. _The Bethuck._--The particular division to which the aborigines of Newfoundland belonged, has been a matter of doubt; some writers considering them to have been Eskimo, others to have been akin to the Micmacs, who have now a partial footing in the island. Reasons against either of these views are supplied by a hitherto unpublished Bethuck vocabulary with which I have been kindly furnished by my friend Dr. King, of the Ethnological Society. This makes them a _separate section of the Algonkins_,[122] and such I believe them to have been. 2. _The Shyennes._--It has been already stated that the present Shyenne area is isolated. This had a tendency to mislead inquirers and to originate the notion that the Shyennes were Sioux. Again,--in a treaty between the United States and the Shyennes, in 1825, the names of the chiefs who signed are Sioux. This misled also. Still, on the evidence of Mr. Kennet M'Kenzie, of the St. Louis Fur Company, who informed Mr. Gallatin that "there was not at that time any European interpreter for the Shyenne, that the treaty was carried on through the medium of some Sioux, and that he had reason to believe that the names subscribed to it were Sioux translations of those of the Shyenne chiefs," their position was left as doubtful by that philologist.
