Cayugas at their lake, and the Senecas or Sonontowans, the Great Hill people, at a lofty eminence which rises south of the Canandaigua lake. In due time, as he is careful to record, the same result happened as had occurred with the Caniengas. The language of each canton "was altered;" yet not so much, he might have added, but that all the tribes could still hold intercourse, and comprehend one another's speech. A wider isolation and, consequently, a somewhat greater change of language, befell the "sixth family." Pursuing their course to the west they touched Lake Erie, and thence, turning to the southeast, came to the Allegheny river. Cusick, however, does not know it by this name. He calls it the Ohio,--in his uncouth orthography and with a locative particle added, the Ouau-we-yo-ka,--which, he says, means "a principal stream, now Mississippi." This statement, unintelligible as at the first glance it seems, is strictly accurate. The word Ohio undoubtedly signified, in the ancient Iroquois speech, as it still means in the modern Tuscarora, not "beautiful river", but "great river." [Footnote: See Appendix, note B.] It was so called as being the main stream which receives the affluents of the Ohio valley. In the view of the Iroquois, this "main stream" commences with what we call the Allegheny river, continues in what we term the Ohio, and then flows on in what we style the Mississippi,--of which, in their view, the upper Mississippi is merely an affluent. In Iroquois hydrography, the Ohio--the great river of the ancient Alligewi domain--is the central stream to which all the rivers of the mighty West converge.
