Perhaps I am like Carrie Jensen, the sister of one of my hired men. She had never been out of the cornfields, and a few years ago she got despondent and said life was just the same thing over and over, and she didn't see the use of it. After she had tried to kill herself once or twice, her folks got worried and sent her over to Iowa to visit some relations. Ever since she's come back she's been perfectly cheerful, and she says she's contented to live and work in a world that's so big and interesting. She said that anything as big as the bridges over the Platte and the Missouri reconciled her. And it's what goes on in the world that reconciles me.
