The Blackfeet, the Crows (their inveterate enemies), the Crees, the Assinneboins, occupying the country from the mouth of the Yellow Stone River to Lake Winnipeg, the Ojibbeways or Chippeways, holding the southern shores of Lake Superior, the Lake of the Woods, and the Athabasca; the Flatheads, on the head-waters of the Columbia; and the Cherokees, removed from Georgia to the upper waters of the Arkansas, are also important tribes; as are the Muskogee or Creek Indians, recently transplanted from Georgia and Alabama to the Arkansas, seven hundred miles west of the Mississippi. The Seminolees are also in process of removal to the Arkansas, as are the Enchees, once a powerful tribe, but now merging into the above, and with them forming one people. Most of these tribes, as well as others that we have not room even to specify, have been reduced, by the different scourges before alluded to, in a manner frightful to contemplate. The Delawares, for example, have lost 10,000 by small-pox alone; and from a large and numerous tribe, now reckon 824 souls only! The Senecas, Oneidas and Tuskaroras, once forming part of that great compact known as the “Six Nations,” are now a mere name. The Kaskaskias, the Peorias, and the Piankeshaws, have fallen victims to the practice of drinking spirits, and to the diseases this fearful habit engenders, so that all are now reduced to a few individuals. Some tribes are totally extinguished;--as, for example the hospitable and friendly Mandans, of whom even the traders themselves report that no one of them was ever known to destroy a white man. These afford a melancholy instance of the rapidity with which the extermination before alluded to is effected. In the year 1834, when Mr Catlin visited these warlike and spirited, yet kindly dwellers of the woods, their number was 2000; three years after, they were infected by the traders with small-pox; and this, with certain suicides committed by individuals who could not survive the loss of all they loved, destroyed the whole tribe, some forty excepted, who were afterwards cut off by their enemies of a neighbouring tribe, so that at this moment not a Mandan exists over the whole wide continent, where, before the baleful appearance of the white man, his free ancestors ranged so happily.
