Keep close to Nature's heart, yourself, and break clear away, once in a while, and climb a mountain or spend a week in the woods. Wash your spirit clean from the earthstains of this sordid, gold-seeking crowd in God's pure air. It will help you in your efforts to bring to these men something better than gold. Don't lose your freedom and your love of the Earth as God made it.
