The third group in this western region consists of the Pawnees and Arickarees,[39] of the Platte valley in Nebraska, with a few kindred tribes farther to the south. [Footnote 39: For the history and ethnology of these interesting tribes, see three learned papers by J. B. Dunbar, in _Magazine of American History_, vol. iv. pp. 241-281; vol. v. pp. 321-342; vol. viii. pp. 734-756; also Grinnell's _Pawnee Hero Stories and Folk-Tales_, New York, 1889.] [Sidenote: Maskoki family.] Of the three groups eastward of the Mississippi we may first mention the Maskoki, or Muskhogees, consisting of the Choctaws, Chickasaws, Seminoles, and others, with the Creek confederacy.[40] These tribes were intelligent and powerful, with a culture well advanced toward the end of the lower period of barbarism. [Footnote 40: These tribes of the Gulf region were formerly grouped, along with others not akin to them, as "Mobilians." The Cherokees were supposed to belong to the Maskoki family, but they have lately been declared an intrusive offshoot from the Iroquois stock. The remnants of another alien tribe, the once famous Natchez, were adopted into the Creek confederacy. For a full account of these tribes, see Gatschet, _A Migration Legend of the Creek Indians_, vol. i., Philadelphia, 1884.] [Sidenote: Algonquin family of tribes.] The Algonquin family, bordering at its southern limits upon the Maskoki, had a vast range northeasterly along the Atlantic coast until it reached the confines of Labrador, and northwesterly through the region of the Great Lakes and as far as the Churchill river[41] to the west of Hudson's Bay. In other words, the Algonquins were bounded on the south by the Maskoki,[42] on the west by the Dakotas, on the northwest by the Athabaskans, on the northeast by Eskimos, and on the east by the ocean. Between Lake Superior and the Red River of the North the Crees had their hunting grounds, and closely related to them were the Pottawatomies, Ojibwas, and Ottawas. One offshoot, including the Blackfeet, Cheyennes, and Arrapahos, roamed as far west as the Rocky Mountains. The great triangle between the upper Mississippi and the Ohio was occupied by the Menomonees and Kickapoos, the Sacs and Foxes, the Miamis and Illinois, and the Shawnees. Along the coast region the principal Algonquin tribes were the Powhatans of Virginia, the Lenape or Delawares, the Munsees or Minisinks of the mountains about the Susquehanna, the Mohegans on the Hudson, the Adirondacks between that river and the St. Lawrence, the Narragansetts and their congeners in New England, and finally the Micmacs and Wabenaki far down East, as the last name implies. There is a tradition, supported to some extent by linguistic evidence,[43] that the Mohegans, with their cousins the Pequots, were more closely related to the Shawnees than to the Delaware or coast group.
