Letter from John Burroughs to Theodore Roosevelt

John Burroughs read Theodore Roosevelt’s reply to Abbott Thayer in The Outlook, “You cut the ground from under him every time.” Burroughs has not yet seen Thayer’s article in Popular Science Monthly, but plans to get it upon his return home. Burroughs sends Roosevelt the table of contents for his new book. The volume he hopes to put out next year will include Pine Knot. Burroughs suggests that Roosevelt read Henri Bergson’s Creative Evolution.
