My dear Mr. Secretary:
It was good to see a letter from you written in Washington, because I have been anxious about your health and am delighted that you are back. I hope with all my heart that you are feeling better and will take the rest necessary entirely to restore your health.
It was kind and thoughtful of you to write me on my birthday and you may be sure I appreciate it as coming from on whom I count a real and invaluable friend.
Cordially and sincerely yours,
