The considerations which favor the policy of seclusion with more or less of industrial constraint are so direct and familiar, and are sustained by so general a concurrence of testimony and authority, that they will not require us greatly to protract this paper in their exposition and enforcement. These considerations are four in number; three of them having especial reference to the interests of the Indians, the fourth bearing on the welfare of the States to be formed out of the territory now roamed over by the native tribes. First: so long as an Indian tribe is left to its own proper forces and dispositions, free from all foreign attraction, it is not only easily governed, but the whole body obeys the recognized law of the community with almost absolute unanimity. No expressions would be too strong to characterize the social homogeneity of an Indian tribe, and the complete domination of the accepted ideas of right and wrong, of honor and baseness. Public opinion is there conclusive upon every individual; and the spectacle, seen in every town and village with us, of large numbers openly practising that which public opinion reprobates, or refusing to do that which public opinion prescribes, is wholly unknown. We do not say that this is the most desirable as the ultimate form of society; but this tyranny of sentiment may and should be made a most powerful auxiliary for good in the early stages of industrial and social progress for this people. Second: it is unfortunately true, that, when the Indian is, by the powerful attraction of a race which his savage breast never fails to recognize as superior, released from the control of the public sentiment which he has been accustomed to obey, he submits himself by an almost irresistible tendency to the worst and not to the best influences of civilized society. While there are undeniably exceptions to this statement, it is supported by such a mass of melancholy evidence in the history of scores of tribes once renowned for all the native virtues, that no one has the right to advocate the introduction to such influences of uninstructed and unprovided tribes, unless he is prepared to contemplate the ruin of nine-tenths of the subjects of his policy. Nor is it the worst elements of the Indian which thus submit themselves to the worst elements of the white community. The very men who bear themselves most loftily, according to the native standards of virtue, are quite as likely to fall, under exposure to white contact, as are the weakest of the tribe. Their familiar attractions all broken, their immemorial traditions rudely dispelled, their natural leadership destroyed, the members of a wild tribe, strong and weak together, become the easy prey of the rascally influences of civilized society.
