"[Speaking to a crowd regarding the sale of tribal land to the US Government] My friends, you have all heard what my father-in-law says, but I do not think he is right. He believes what the white people tell him; but this is only another trick of the whites to take our land away from us, and they have played these tricks before. We do not want to trust the white people. They come to use with sweet talk, but they do not mean it. We will not sign any more papers for these white men."
