The officers of the Indian Affairs Office in Washington City give an enumeration of the Indian tribes within the bounds of the Confederate and United States with the population of each. They state the aggregate number at 238,079. The largest tribes are the Creeks 25,000, the Cherokees 17,350, the Choctaws 16,000, the Navajoes 15,000, the Sioux 14,636. The Comanches, of whom we have heard so much, are stated at only 1,800; the Apaches 7,300.
