_Grand-Ronde Agency._--The Indians at this agency comprise the Molalla, Clackama, Calapooia, Molel, Umpqua, Rogue River, and other bands, seventeen in all, with a total population of eight hundred and seventy. The reservation upon which these bands are located is in the north-western part of the State. It contains 69,120 acres, and was set apart for their occupation by treaty of Jan. 22, 1855, with the Molallas, Clackamas, &c., and by executive order of June 30, 1857. Some portions of this reservation are well adapted to grain-raising, though much of it is rough and heavily timbered. An allotment of land in severalty has been directed to be made, much to the gratification and encouragement of the tribes. These Indians are inclined to industry, and show commendable zeal in cultivating their farms, growing crops which compare favorably with those of their white neighbors. Their customs and habits of life also exhibit a marked improvement. One school is in operation, with an attendance of fifty scholars. _Siletz Agency._--The Indians at this agency are the Chasta Scotons, and fragments of fourteen other bands, called, generally, Coast-tribes, numbering altogether about 2,500. These Indians, including those at the Alsea sub-agency, have a reservation of 1,100,800 acres set apart for them by treaty of Aug. 11, 1855; which treaty, however, has never been ratified, although the reservation is occupied by the Indians. They were for a long time much averse to labor for a support; but recently they have shown more disposition to follow agriculture, although traditionally accustomed to rely chiefly upon fish for food. Many already have their farms well fenced and stocked, with good, comfortable dwellings and out-houses erected thereon. There is no reason why they should not, in time, become a thoroughly prosperous people. The failure to make allotments of land in severalty, for which surveys were commenced in 1871, has been a source of much uneasiness to the Indians, and has tended to weaken their confidence in the good intentions of the government. One school is in operation on the reservation, with an attendance of twenty scholars. None of the tribes or bands at this agency have any treaty relations with the United States, unless it may be a few members of the Rogue-River band, referred to under the head of the Grand-Ronde agency.
