San Antonio, Texas.--My Dear Chum: Dad and I left Hot Springs because the man who kept the hotel where we stopped got prejudiced against me. I suppose I did carry the thing a little too far. You see dad has got into this breakfast food habit, and reads all the advertisements that describe new inventions of breakfast food, and he has got himself so worked up over the bran mash that he is losing appetite for anything substantial, and he is getting weak and nutty. Ma told me when I went away with dad that she wanted me to try my best to break dad of the breakfast food habit, and I promised to do it. Say, kid, if you ever expect to succeed in life, you have got to establish a reputation for keeping your promises.
