If a man is rich and strong anywhere, it must be on his native soil. Here I have been these forty years learning the language of these fields that I may the better express myself. If I should travel to the prairies, I should much less understand them, and my past life would serve me but ill to describe them. Many a weed here stands for more of life to me than the big trees of California would if I should go there. We need only travel enough to give our intellects an airing.
