With the exception of the Shyennes, who seem to have moved within the historical period, the Algonkin area is _continuous_; but though _continuous_, it is not _uninterrupted_. The important class of the Mohawk, or Iroquois, tribes, is different from the Algonkin. It lies _within_ the Algonkin area, surrounded by Algonkins, but not itself Algonkin. THE IROQUOIS. Measured by the extent of ground that it covers the Iroquois class is of less importance than the Algonkin. Measured by its prominence in history it is equal or greater. The _Five Nations_ were Iroquois. The once formidable _Mohawks_ were Iroquois. Before the arrival of the Europeans the Five Nations were dominant over their Algonkin neighbours; and after the arrival of the Europeans the Iroquois warriors were more feared than those of the Algonkins. At one time the head of the Algonkin confederacy was an Iroquois chieftain. It has been stated above that the Iroquois are, at present, encompassed (or nearly encompassed) by Algonkins; so as to have become isolate in respect to the other classes of Indians, and cut off from contact with them. This, and more than this, is the case. Portions of the Iroquois family are cut off from each other, so that in coming to the details we shall expect to hear of the Northern division of the Iroquois, and of the Southern division of the Iroquois. At present it is sufficient to state that such a division exists, and that the localities for the Northern Iroquois are the parts about Lake Huron; for the Southern, North Carolina. In the latter locality alone are they in contact with tribes other than the Algonkin. _Area._--Discontinuous. _Divisions._--_a._ Northern Iroquois. _b._ Southern Iroquois. _Sub-divisions._--_a._ Northern Iroquois. 1. The Five Nations=The Mohawks, the Oneidas, the Onondagoes, the Senecas, and the Cayugas. 2. The Confederacy (?) of the Hurons (or Wyandots), the Erigas, the Andastes, and the Attiondarons, the Tionontates, the Anies(?), &c. _b._ Southern Iroquois.--The Tutelo, Nottoway, Meherrin, and Tuscaroras. _Localities._--_a._ For the Northern Iroquois the parts about and between Lakes Huron, Ontario, and Erie. _b._ For the Southern Iroquois.--North Carolina. Separation effected by tribes of the Algonkin division, especially the Delawares. The Iroquois and Algonkins exhibit in the most typical form the characteristics of the North American Indians as exhibited in the earliest descriptions, and are the two families upon which the current notions respecting the physiognomy, habits, and moral and intellectual powers of the so-called Red Race are chiefly founded. THE SIOUX. _Area._--Central North America, between the Mississippi and the Rocky Mountains, east and west. Between Lake Winebago and the Arkansas, north and south. The valley of the Missouri. The water-system of Lake Winebago. One division east of the Mississippi.
