June 6, 1924 Dear Gregg: I am sorry you are going. I don't know what in the devil I am going to do without you. It is true I have not seen much of you in the last few weeks, but I have always known where I could get you when I wanted you to help out on anything that came up. I am going to miss you frightfully, but on the other hand I am satisfied that you are going to have a wonderful year or two and that you are going to accomplish an enormous amount of good work for the Division as well as add to your own training. I, of course, count on seeing you occasionally during the winter, but I am counting especially on your return when I hope we may continue our work together. Don't work too hard; get enough vacation and relaxation to give zest to the real work; and don't feel that you have to cover all Europe at once or to reform medical education in a year. Take plenty of time for languages and for reading. I am counting on you to do a splendid job, and I know you will. Don't let the job interfere with giving Mrs. Gregg a good time or with the early education of Alan. Don't hesitate at any time to let us know when we can do anything for you here. With my best regards to the entire Gregg entourage, Yours sincerely, R.M.P.
