Communications have been received from Dr. Elijah White, sub-agent for the Indians in Oregon Territory, dated, severally, November 15, 1843, and March 18, 1844.----They contain much of interest in considerable detail. The establishment of white settlements from the United States, in that remote region, seems to be attended with the circumstances that have always arisen out of the conversion of an American wilderness into a cultivated and improved region, modified by the great advance of the present time in morals, and benevolent and religious institutions. It is very remarkable that there should be so soon several well-supported, well-attended, and well-conducted schools in Oregon. The Nez Percé tribe of Indians have adopted a few simple and plain laws of their code, which will teach them self-restraint, and is the beginning of government on their part. It is painful, however, to know that a distillery for the manufacture of whisky was erected and in operation west of the Rocky Mountains, which, however, the sub-agent, sustained by the resident whites, broke up and destroyed. There was, in February last, an affray between a very boisterous and desperate Indian and his party and a portion of the settlers, which ended in the death of several of the combatants. This unfortunate affair was adjusted, as it is hoped, satisfactorily and permanently, by the sub-agent, though he seems to apprehend an early outbreak. I trust he is mistaken. Respectfully submitted, T. HARTLEY CRAWFORD. Hon. WILLIAM WILKINS, Secretary of War. CHAPTER XXXII. Dr. E.
