"The limits of their accustomed range are rapidly contracting, and their means of subsistence undergoing a corresponding diminution. The white man is advancing with rapid strides upon all sides of them, and they are forced to give way to his encroachments. The time is not far distant when the buffalo will become extinct, and they will then be compelled to adopt some other mode of life than the chase for a subsistence.... No man will quietly submit to starvation when food is within his reach, and if he cannot obtain it honestly he will steal it or take it by force. If, therefore, we do not induce them to engage in agricultural avocations we shall in a few years have before us the alternative of exterminating them or fighting them perpetually. That they are destined ultimately to extinction does not in my mind admit of a doubt. For the reasons above mentioned it may at first be necessary for our government to assert its authority over them by a prompt and vigorous exercise of the military arm.... The tendency of the policy I have indicated will be to assemble these people in communities where they will be more readily controlled; and I predict from it the most gratifying results." Another well-informed army officer, Colonel Richard Dodge, himself a hunter, a trailer, and a rider able to compete with the savages in their own fields, penetrated to the heart of the Indian problem when he wrote: "The conception of Indian character is almost impossible to a man who has passed the greater portion of his life surrounded by the influences of a cultivated, refined, and moral society.... The truth is simply too shocking, and the revolted mind takes refuge in disbelief as the less painful horn of the dilemma. As a first step toward an understanding of his character we must get at his standpoint of morality. As a child he is not brought up.... From the dawn of intelligence his own will is his law. There is no right and no wrong to him.... No dread of punishment restrains him from any act that boyish fun or fury may prompt. No lessons inculcating the beauty and sure reward of goodness or the hideousness and certain punishment of vice are ever wasted on him. The men by whom he is surrounded, and to whom he looks as models for his future life, are great and renowned just in proportion to their ferocity, to the scalps they have taken, or the thefts they have committed. His earliest boyish memory is probably a dance of rejoicing over the scalps of strangers, all of whom he is taught to regard as enemies. The lessons of his mother awaken only a desire to take his place as soon as possible in fight and foray. The instruction of his father is only such as is calculated to fit him best to act a prominent part in the chase, in theft, and in murder.... Virtue, morality, generosity, honor, are words not only absolutely without significance to him, but are not accurately translatable into any Indian language on the Plains."
