However, a vocabulary of Lieutenant Abert has since settled the matter, "in which no affinity whatever is discovered with the Sioux. Although from its nature it contains but a small number of primitive words, or of those for which we have equivalents in other languages, there are enough to establish the fact that the Shyennes are, like the Black-feet, an Algonkin tribe. Out of forty-seven Shyenne words for which we have equivalents in other languages, there are thirteen which are indubitably Algonkin, and twenty-five which have affinities more or less remote with some of the languages of that family. Of these last I would have rejected more than one half had they stood alone, but they corroborate, to some extent, the evidence afforded by the words, the etymology of which is clear. The nine remaining words (out of the forty-seven), which have no apparent affinity with the Algonkin, are _hill_, _mountain_, _stone_, _little_, _white_, and the numerals VI, VII, VIII, IX, on comparing the vocabulary with those of other families, I could discover no other words which had any resemblance but the following:--_little_=_nakee_, Shyenne, _okeye_, Wyandott; _fire_=_sist_, Shyenne; _ojishta_, _ojista_, Seneca, Oneida."[123] Furthermore, the evidence of Lewis and Clarke, confirmed by that of M'Kenzie and Gallatin, shows that the separation of the Shyennes from the other Algonkins, took place within the historical period. "They were originally settled on a stream called Chayenne, or Cayenne, an upper branch of the Red River of Lake Winnepeg, from which they were driven away by the Sioux; an account which is confirmed by Alexander M'Kenzie. They retreated west of the Missouri, below the river Warreconne, where their ancient fortifications still existed in 1804. Thence they were again compelled to retreat farther west, near the Black Hills, on the head branches of the river which now bears their name."[124] That the evidence of the Shyenne numerals, the only part of Lieut. Abert's vocabulary then known to him, made the Shyennes Algonkin, was also stated by the present writer at the meeting of the British Association, in 1847, at Oxford.--_Transactions of the Sections_, p. 123. 3. _The Blackfoots._--Until lately all that was known of the Blackfoot language was from two short vocabularies, one of Humphreville's and one of Mr. Catlin's. The addition of a third in MS. has fixed the language as Algonkin; such being the opinion formed independently by both Mr. Gallatin[125] and the present writer, who was favoured by Dr. Prichard with the MS. It is further confirmed by a tabulated vocabulary of Mr. Howse's, now in the press.[126]
