Fonds consists of twelve daily diaries, intermittently spanning between 1907 and 1948, that contain entries pertaining to daily farm operations. Included, though unrelated, are two ledgers from a Berlin (Kitchener), Ontario general store for the years 1893 and 1907. Accounts listed include purchases by John King, father of William Lyon Mackenzie King, that help document the lifestyle of the King family while living at Woodside, now a National Historic Site.
