Sims dated March 23, 1938, commenting on Harvey's report of Florence's increased good health and on Harvey's opinion of John Buchan, Lord Tweedsmuir's biography of the Roman Emperor Augustus. King offers to send Buchan Harvey's comments. King is sending Harvey the Hansard he requested, "containing my speech on the Export of Power Bill. The communications from the United States, recently received, make it pretty clear that I have not been far wrong in my estimate of what the attitude of the United States would be, toward the attitude taken by the government of Ontario, and not far wrong in the strategy I have employed in not permitting Hepburn's behaviour either to embarrass me or Members of the Party in the Federal Parliament. He has only himself to thank for the door of the United States being shut so completely in his face." King comments that his own health is better due to his own determination not to take on more in a day than he can handle without fatigue.
Salutation: "My dear Peter [handwritten]"; Signature: "With kindest remembrances and best of wishes to Florence and yourself, Believe me, as always, dear Peter [typewritten], Yours affectionately, Billy [handwritten]."
