OF INDIAN LANGUAGES. While the literature relating to the languages of North America is very extensive, that which relates to their classification is much less extensive. For the benefit of future students in this line it is thought best to present a concise account of such literature, or at least so much as has been consulted in the preparation of this paper. 1836. Gallatin (Albert). A synopsis of the Indian tribes within the United States east of the Rocky Mountains, and in the British and Russian possessions in North America. In Transactions and Collections of the American Antiquarian Society (Archæologia Americana) Cambridge, 1836, vol. 2. The larger part of the volume consists of Gallatin’s paper. A short chapter is devoted to general observations, including certain historical data, and the remainder to the discussion of linguistic material and the affinities of the various tribes mentioned. Vocabularies of many of the families are appended. Twenty-eight linguistic divisions are recognized in the general table of the tribes. Some of these divisions are purely geographic, such as the tribes of Salmon River, Queen Charlotte’s Island, etc. Vocabularies from these localities were at hand, but of their linguistic relations the author was not sufficiently assured. Most of the linguistic families recognized by Gallatin were defined with much precision. Not all of his conclusions are to be accepted in the presence of the data now at hand, but usually they were sound, as is attested by the fact that they have constituted the basis for much classificatory work since his time. The primary, or at least the ostensible, purpose of the colored map which accompanies Gallatin’s paper was, as indicated by its title, to show the distribution of the tribes, and accordingly their names appear upon it, and not the names of the linguistic families. Nevertheless, it is practically a map of the linguistic families as determined by the author, and it is believed to be the first attempted for the area represented. Only eleven of the twenty-eight families named in this table appear, and these represent the families with which he was best acquainted. As was to be expected from the early period at which the map was constructed, much of the western part of the United States was left uncolored. Altogether the map illustrates well the state of knowledge of the time. 1840. Bancroft (George). History of the colonization of the United States, Boston. 1840, vol. 3.
