_Yavapais and Apaches._--These Indians are estimated to number from 8,000 to 12,000, the lower estimate being the more reasonable. Their ranging grounds are in the central, northern, and eastern parts of the Territory. Most of them have long been hostile to the government, committing numerous robberies and murders. Earnest efforts have been made during the past year to settle them on reservations, three of which, viz., Camp Apache, Camp Grant, and Camp Verde, were set apart for their occupancy by executive order dated Nov. 9, 1871. These efforts, however, have not resulted very successfully; the Indians occasionally coming upon the reservations in large numbers, but leaving without permission, and, indeed, defiantly, whenever so disposed, oftentimes renewing their depredations before their supplies of government rations are exhausted. Many of the bands of this tribe (if it can be called a tribe; habits, physical structure, and language all pointing to a great diversity in origin among the several bands) are seemingly incorrigible, and will hardly be brought to cease their depredations and massacres except by the application of military force. NEVADA. The tribes residing in Nevada are Pah-Utes, Pi-Utes, Washoes, Shoshones, and Bannocks, and are native to the districts inhabited by them respectively. _Pah-Utes._--These Indians, numbering about 6,000, inhabit the western part of the State. Two reservations have been set apart for them,--one known as the Walker River, the other as the Pyramid Lake reservation, containing each 320,000 acres. These Indians are quiet, and friendly to the whites, are very poor, and live chiefly upon fish, game, seeds, and nuts, with such assistance as the government from time to time renders them. They show considerable disposition to labor; and those on the reservations, especially the Walker River reservation, are cultivating small patches of ground. The Pyramid Lake reservation affords, in addition, excellent fishing, and the surrounding settlements a ready market for the catch over and above what the Indians require for their own consumption. No schools have been established for these Indians. They have no treaty relations with the government, and receive no annuities. _Pi-Utes._--The Pi-Utes, numbering probably 2,500, inhabit the south-eastern part of the State. They have no reservation set apart for them; nor have they any treaty with the United States. They roam about at will, are very destitute, and obtain a living principally by pilfering from the whites, although a few of them are engaged in a small way in farming. But very little can be done for these Indians by the government in their present unsettled condition. They should be brought upon one of the reservations set apart for the Indians in Nevada, or upon the Uintah reservation in Utah, where they could receive suitable care, and proper instruction in the arts of civilized life.
