"Good!" For a half-hour he walked over the herd-grounds, crossing, circling, and stopping; then back as near to the post as he dared. At last he turned and rode away. He was thoroughly familiar with the vicinity of the camp, and had no trouble so long as the post lights guided him. The mountain boy had brought little to the soldier camp but the qualities of mind which distinguished his remote ancestors of the north of Europe, who came out of the dark forests clad in skins, and bearing the first and final law of man, a naked sword on a knotted arm. An interval of many centuries intervened between him and his fellows; all the race had evolved, all the laws which they had made for the government of society, all the subtle customs which experience had decreed should circumscribe associates, were to him but the hermit's gossip in idle hours at the cabin. The bar sinister was on his shield; his credentials were the advice of an unreal person to fight in common with the whites. He came clad in skins on a naked horse, and could barely understand English when it was in the last adulteration; and still he had made his way without stumbling until the fatal evening. Now he was fleeing for life because he had done two of the most natural things which a man can do. "Good-by, good-by, white men, and good-by, white woman; the frost is in your hearts, and your blood runs like the melting snow from the hills. When you smile, you only skin your fangs; and when you laugh, your eyes do not laugh with you. You say good words which mean nothing. You stroke a man's back as a boy does a dog's, and kick him later as a boy does. You, woman, you who pick men's hearts and eat them as a squaw does wild plums, I want no more of you. You, Butler, I wish were out here in the dark with me; one of us would never see the sun rise. You would force me!" and the scout vented himself in a hollow laugh which was chill with murder. The lights were lost behind the rise of the land, and the pony trotted along. No horse or man not raised on the buffalo range could travel in that darkness; but both of them made steady progress. "Those Indians will have to crawl on their knees a whole day to pick up my pony tracks on the herd ground. The Crows will never try to follow me; the Shoshone may when the white men offer a reward. That fool of a boy may see his chance to even up the insult which I gave before the woman. He can shake her hand now for all I would do. I will ride for two hours before the sun comes, and then let the pony feed." Patting his horse's neck, he added: "And then, my boy, we will blind our trail in some creek. I will rub the medicine on your heels, you shall gallop until dark, and no horse in that camp will get near enough to spoil my sleep."
