The fonds consists of Turner's handwritten diary (1911-1912). Much of the diary refers to his construction activities and to the political events of the time. The diary is written in a copying book that interleaves an "onion skin"-type paper with regular paper to allow for the creation of a copy. In this instance the copies appear to have been sent to his family - the first entry is dated November 12-13, 1911 and is addressed to "Mother dearest & all."
