Materials include a Canadian dress uniform and hat, which belonged to Hugh B. Brown when he was an officer during the first World War (1914-1918). The uniform is red with white trim and gold metal on the shoulders. The hat is black and white.

The folder contains a handwritten letter dated 24 March 1915 and addressed O. A. Kirkham. J. Walter Low writes about the Boy Scouts of Canada, the possibility of Italy entering World War I, and that "Hugh Brown looks fine in his new field uniform and has an excellent squadron of well trained mounted rifles."
