Aug. 19
Dear John,
Just a note for your birthday – It is now about 0700 and before breakfast just out of Ogden Utah. It is raining and a little cool.
I’m going to send Mother a telegram at O. So again Happy Birthday.
Daddy

Very cool letter all the way around!
How cool to have a letter written on the train stationery.
All this is news to me, i.e., the return to San Francisco.
