Excerpt: "The wilderness rolled away to north and to south, and also it rolled away to east and to west, an unbroken sweep of dark, glossy green. Straight up stood the mighty trunks, but the leaves rippled and sang low when a gentle south wind breathed upon them. It was the forest as God made it, the magnificent valley of North America, upon whose edges the white man had just begun to nibble."
