They pulled two seats together so Darl could sit by the window. One of them sat beside him, the other sat on the seat facing him, riding backward. One of them had to ride backward because state's money has a face to each backside and a backside to each face, and they are riding on the state's money which is incest. A nickel has a woman on one side and a buffalo on the other; two faces and no back. I don't know what that is. Darl had a little spy-glass he got in France at the war. In it it had a woman and a pig with two backs and no face. I know what that is.
