The D'Aigle papers fall into three series: diaries, correspondence and a scrapbook of photographs and memorabilia. The diaries (1912-1914, 1927, 1935-1952) are largely devoted to a day-by-day account of prospecting journeys. Correspondence with members of his family, partners, prospective financial backers and government mining bureaus covers the years 1900-1959. The scrapbook contains personal mementos, newsclippings about D'Aigle, photographs of his journeys, lists of supplies for prospecting trips, and maps, some drawn by D'Aigle himself.

Papers consist of personal correspondence, including substantial family correspondence, diaries, journals, engagement books, ledgers, menus, manuscript poems, galley proofs, lecture notes, scrapbooks, and photographs. It includes correspondence, 1874-1935; a diary of Drummond's trip to Great Britain, 1902; dinner menus, 1902-1903; engagement books, 1902-1906; galley proofs, 1905-1911; Journal of Impressions kept at Savanna la Mar, Jamaica, Windsor and Montreal, 1903-1911; lecture notes taken at McGill, 1878-1882; ledgers containing financial entries and patients' accounts during Drummond's practice in Knowlton and Montreal, 1885-1889; notebooks containing manuscripts poems, drafts and clippings, 1894-1909; scrapbooks related to literary topics, including clippings about Drummond's public readings, and book reviews, 1854-1907 and scrapbooks related to Drummond's dogs, 1890-1907. There are also some papers of Mrs. W.H. Drummond, including a typescript of her Life of W.H. Drummond; and diaries recording her trips to United States and Canada, 1892, 1903.

The project files which occupy most of the archives of J.T. Donald and Co. fall into two series: ordinary business and special assignments. Both series contain the firms report's, and correspondence. Special assignments were largely connected with wartime armaments production. A few files concern work for the Imperial Munitions Board in World War I, but most consist of reports for the Chemical and Explosives Branch of the Department of Munitions and Supply, 1939-1948. Ordinary projects involve consultation for food, pulp and paper, petroleum, and chemical manufacturies, as well as for some government departments, 1888-1940. Outgoing correspondence from 1881 to 1909 is contained in letterbooks. A file of legal documents, 1924-1946, refer to claims against the company, agreements, and partnerships. Also included are an undated notebook on chemical analysis, and scrapbooks and files of newsclippings of professional interest (e.g. reports of explosions caused by oil and gas) covering the period 1916-1958. There are also reports on mining and energy sources prepared by Donald alone and also in partnership with J.H. Ross for various private and government bodies.

A small number of letters between Graham and E.B. Tiffany, an offical of Henry Birks and Co., discuss the occurrance of diamonds in Canada (1949). A record of Graham's work as a teacher in his field is a set of notes on the use of the petrographic microscope.

Fonds consists of six letters, with four manuscript letters from Rilke written between 1896 and 1922 and two discussing letters discussing these. The four letters from Rilke are addressed to various correspondents, including on 8 November 1896 to the author Gabriele Reuter regarding her book, 15 October 1904 to Anette Vedel, and 9 July 1907 to an unidentified correspondent. The fourth letter dates likely from August or September 1922 and is addressed to Elfriede Nicolaus. The two later letters which discuss the Rilke letters include one dated 13 December 1954 from Hedvig Wahlgren regarding the date of the 1922 letter to Nicolaus and one dated 29 November 1955 from Ruth Fritzsche (née Rilke) to McGill Librarian Richard Pennington.

Fonds consists of private correspondence related to Clarke’s professional work, a few musical manuscripts and texts of addresses, and a large body of personal financial accounts. His correspondence falls into two series. The general correspondence discusses arrangements for concerts in England and Canada, compositions (his own and others), the problems of musical life in Montréal, and private matters such as travel arrangements and club memberships. Much of the correspondence concerns the social aspects of music and of Clarke's position: patronage of musical events, organization of celebrations for the Jubilee of 1935 and the Coronation in 1937, and complementary tickets to concerts. Amongst his correspondents are a number of musicians and composers, including Sir Ernest MacMillan and Healey Willan. A very small percentage of this material concerns university business. A second series consists of invitations to address or attend meetings, with related correspondence. Both series cover the years 1929-1952.

Over half of the papers consist of personal financial accounts (1929-1953) for Clarke's insurance, taxes, apartment rental, various domestic expenses (e.g. groceries), telegrams, travel, and transportation.

There are two undated addresses: one on Christmas and the second on musical education. There are also two music sketchbooks from around 1920. Pictorial material comprises two photographs (approximately 1923, 1954) and a pencil sketch (1933).

Bovey's papers document his involvement with a number of organizations, his political, literary, and military careers, and his travels. His files as president of the Canadian Handicrafts Guild, 1930-1936, include reports, correspondence and speeches, while those connected with the Canadian Legion Educational Services also include photographs and printed material, 1939-1946. The C.B.C. series comprises programmes, draft speeches and letters, 1936-1944. His political correspondents include St. Laurent and MacKenzie King, 1940-1944. Speeches made by Bovey before the Legislative Council, business and other groups discuss a wide range of political, social and educational issues are supplemented by clipping files on Québec politics. Bovey's literary ventures generated correspondence and book reviews, as well as manuscript poems, 1939-1941, n.d., while his World War I military service is the subject of a small file of correspondence, 1915-1953. Finally, Bovey assembled scrapbooks of photographs and souvenirs of his voyages between 1930 and 1939. For Bovey's files as director of Extra-Mural Relations and Extension at McGill, see McGill Administrative Records, Record Group 44.

Fonds consists of correspondence and literary manuscripts, documenting all aspects of MacMillan’s career. Biographical background is provided by his own notes on his life and family history. From his student years come certificates and testimonials in support of his application for a Rhodes Scholarship (1904-1909). His war experience is recorded in letters from the front preserved by his family, and by a personal diary for 1917. There are also approximately twenty photographs of Macmillan and his family taken between about 1905 and 1940.

Macmillan's correspondence includes files of letters to his wife (1917-1936) on his war service and political affairs; personal and social letters (1923-1929); political correspondence, including several letters from McKenzie King (1926-1946); letters concerning McGill, including a number from Sir Arthur Currie and from Stephen Leacock (1920-1947); post-retirement correspondence on McGill and public affairs; and correspondence concerning his publications (1920-1960). There are also files of invitations to events at McGill and elsewhere.

The manuscripts fall into two categories: political speeches and literary manuscripts. Besides notes and texts for his own speeches, there are also texts of, and newspaper clippings about speeches written by Macmillan for Sir Arthur Currie and others (1920-1950). Drafts and typescripts of his literary works are supplemented by notes, clippings and correspondence.
