DEAR LITTLE ONES,
"I hope you are having a good time in that stuffy caravan, and manage to avoid blisters. I thought you would like to hear that father has given me leave to go to Sheppey, and stay for three days with Mr. Fowler, who has promised to take me up in an aeroplane. I am also to have riding-lessons, and Aunt Mildred has promised me a pony, being so sorry to hear that I was done out of the caravan trip by a fluke. Uncle Jim has sent me 5 pounds. According to the papers the weather is going to break up directly. Your affectionate and prosperous friend,
WILLIAM ROTHERAM.
