Huron-Iroquois, extending of old from the St. Lawrence to North Carolina; the Algonkin, from Hudson Bay to South Carolina; the Dakotan, from the Mississippi to the Rocky Mountains; the Athabascan, from the Eskimo frontier, within the Arctic circle, to New Mexico; and the Tinné family of languages west of the Rocky Mountains, from the Youkon and Mackenzie rivers, far south on the Pacific slope. With those, as with the more cultured languages, or rather languages of the more cultured races, of Central and Southern America, elaborate comparisons have been made with vocabularies of Asiatic languages; but the results are, at best, vague. Curious points of agreement have, indeed, been demonstrated, inviting to further research; but as yet the evidence of relationship mainly rests on correspondence in structure. The agglutinative suffixes are common to the Eskimo and many American Indian tongues. Dr. H. Rink describes the polysynthetic process in the Eskimo language as founded on radical words, to which additional or imperfect words, or affixes, are attached; and on the inflexion, which, for transitive verbs, indicates subject as well as object, likewise by addition. But, while Professor Flower unhesitatingly characterises the Eskimo as belonging to the typical North Asiatic Mongols; he, at the same time, speaks of them as almost as perfectly isolated in their Arctic home “as an island population.” Nevertheless, the same structure is common to their language and to those of the great North American families already named. All alike present, in an exaggerated form, the characteristic structure of the Ural-Altaic or Turanian group of Asiatic languages.
