John M. Phillips appreciates the pamphlet on “Concealing Coloration in Birds and Mammals” sent by Theodore Roosevelt and thinks it is a valuable contribution to the scientific field. He denigrates Abbott Handerson Thayer’s views on camouflage and is glad that Roosevelt will be writing a letter to the editor of The Open. He also appreciated Roosevelt’s words against William J. Long’s fake natural history.
