The Indians fought because they wanted to keep the west for themselves. They felt as an old chief did, who had been forced to move many times by the white men. One day a military officer came to his wigwam to tell him that he and his tribe must go still further west. The chief said, General, let's sit down on this log and talk it over. So they both sat down. After they had talked a short time, the chief said, Please move a little further that way; I haven't room enough. The officer moved along. In a few minutes the chief asked him to move again, and he did so. Presently the chief gave him a push and said, Do move further on, won't you? I can't, said the general. Why not? asked the chief. Because I've got to the end of the log, replied the officer. Well, said the Indian, now you see how it is with us. You white men have kept pushing us on until you have pushed us clear to the end of our country, and yet you come now and say, Move on, move on.
