Wallis' papers are grouped into three series: general scrapbooks, military scrapbooks, and military diaries. General scrapbooks, covering the years 1908-1977, contain letters, photographs, and printed materials relative to Wallis' career. Some volumes include his diary for the period, and all are heavily annotated. They cover all aspects of his career from high school to post-retirement, with special emphasis on his military career and social life. Military scrapbooks contain the same variety of materials for the period 1911-1969, but are devoted exclusively to Wallis' activities during the two World Wars, and his roles in the Black Watch and as an Honorary A.D.C. Military journals give brief reports of his daily activities form 1941 to 1945.

Booth's autobiographical notes, ca 1949, apparently prepared for a Congregational Yearbook, are supplemented by sixteen photographs, printed notices of Booth's performances as an elocutionist, and diplomas.

Tobin's papers consist of a scrapbook and photo album containing programmes, menus and newspaper clippings concerning the "King Cook" celebrations, 1911-1927, newspaper obituaries and photographs of Medical Faculty professors, programmes for social events of the Medical Society, Pharmaceutical Society and the McGill Employees Association (of which Tobin was secretary) and letters of recommendation from the Medical Students Society, 1921-1931.

The Lyman-Scrimger Family Fonds consists of the papers of the Lyman, Scrimger and Johnston Families. Reverend John Scrimger's daughter married Walter Ernest Lyman and their daughter, Elizabeth, in turn married Wyatt Galt Johnston. Elizabeth's sister is Mary Minta Turnor.

The Lyman-Scrimger papers largely consist of approximately 42 cm of photographs. Two albums contain family portraits, while two others assembled by Albert Clarence Lyman (B.A., 1878) and Walter E. Lyman (B.A., 1881) also include pictures of McGill classmates. The large collection of unbound photographs contain a number of views of Western Canada taken ca. 1900, Montreal scenes, and travel snapshots taken in Europe (ca. 1905-1910). Two scrapbooks compiled by the Reverend John Scrimger contain newsclippings, poems, cards, letters, photographs, and memorabilia of a family or sentimental nature. The reminder of the papers consists of newsclippings, programmes and so forth related to members of the family as well as a few scattered items of correspondence, probably collected by Mrs. Walter Lyman.

The Johnston Family papers comprise Wyatt Galt Johnston’s laundry lists and grocery accounts, ca. 1899; a letter to Elizabeth Johnston from her mother in Lennoxville, 1906; H. Wyatt Johnston’s school reports, 1907-1911; and letters of sympathy and memorial cards sent to H. Wyatt Johnston on the death of his mother Elizabeth Johnston, 1943 and his aunt Mary Tunor, 1945.

Mary Minta Turnor’s papers consists of correspondence, largely with members of her family in the Eastern Townships on domestic news. A few photographs of houses and pets, as well as some recipes, are also included.

Adams' papers are largely concerned with his experiments on the mechanical deformation of rocks. Glass lantern slides, both for lectures and private record, are also included, as well as some materials on his interest in religion and in the history of geology. His scientific research is documented by working papers and experimental materials on rock deformation, 1896-1912. These consist of ten notebooks and one scrapbook recording his experiments, as well as notes, photographs, and carbons of typescript chapters on background literature, equipment used, and specific minerals. There are also graphs recording results, and over 1,000 photographs, glass negatives, and petrographic microscope slides. Adams' index-card bibliography lists articles and reports on Canadian geology and mining (ca 1900-1920). Adams' collection of glass slides and negatives were used for teaching geology and as a private record of his travels and family life. These slides number approximately 1,000, and show mines (particularly in Canada) volcanoes and glaciers, a large collection of views of Mexico, the Laurentians, China, the Rockies, England and Palestine, as well as family and vacation scenes. Also included are two essays, and an outline for a third on the Christian life (1937), short reflexions on his activities from 1937 to 1942, a photocopy of his will (1943), clippings of articles where he is mentioned (1919-1942), and notices of his history of Christ Church Cathedral (1941). Adams' interest in the history of geology is reflected in a manuscript biography of A.R.C. Selwyn, for the centenary of the Geological Society of Edinburgh, and a handful of letters and notes on the early use of the word "geology" (1932). His post-retirement travels resulted in a manuscript essay on mining in Malaya.

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.

Madame Fischer's papers are evenly divided between records of her own career as a performer and material on the Sarah Fischer Concerts. Her performing career is documented by newsclippings, tributes and programmes, reports from the Royal College of Music, and publicity photographs in opera costume. Most of the approximately 50 items of correspondence date from the last five years of her life and concern the disposal of her papers. Taped interviews, in which she discusses her career, include recordings from 1918 and 1925. Material connected with the Sarah Fischer Concerts comprises 143 programmes (1941-1975), press notices, announcements, and a report for 1973-1974. Photographs from this period show Fischer with government and musical celebrities.

The records of the Montreal-Ottawa Conference of the United Church are arranged in the following series:

1. Denominational records prior to Union, 1824-1925
   Records of each of the three parent denominations follow the same general pattern. There are minutes, usually printed, of the national executive body, and original minutes of the local unit corresponding to the geographical boundaries of the present Conference. Papers of associations at this level generally include the files of Sabbath School associations, ministerial associations, missionary societies, and theological colleges. A number of interdenominational clergy and mission groups are also represented; while a special series of correspondence, minutes, and conference reports covers the debates concerning union, 1906-1925. The Methodist materials begin in 1824, and the Presbyterian in 1841, and the Congregational in 1842.

2. Conference records, 1925-
   Minutes of the Conference, and of the Conference-based Women's Missionary Society, Women's Union and United Church Women, are extant from the time of Union. The Montreal Presbytery maintains a record of proceedings, and supports a number of groups and associations (Minister's Wives Association, young peoples' groups, camps, missionary societies, United Church Women) whose work is documented by minutes, financial records and, occasionally, correspondence files. Also included are records of the Joint Theological Colleges of McGill University and of the United Theological College, 1912-1948.

3. Local Churches, 1832-
   Many local churches retain their historical records, including civil registers. The Archives' holdings include records of approximately 75 individual congregations in the Montréal and Québec-Sherbrooke Presbyteries, consisting of minutes of governing bodies, communion rolls, minutes of organizations, accounts, annual reports, and occasionally photographs and architectural drawings. The most substantial and significant records are those of the Erskine and American (from 1832), including records of Canada Education and Home Missionary Society, 1833-1848, St James (from 1820), Zion Congregational (from 1832), and Odelltown (from 1829) congregations.

4. Missionary Work in French Canada, 1848-1861, 1876-1969
   The importance to the United Church and its parent denominations of mission work in French Canada is documented by minutes of the French Canadian Missionary Society (1848-1861), and papers, including sermons, notebooks and correspondence of the French Evangelical Church of Canada (1876-1969).

5. Papers of individuals, 1822-1925
   Papers of individuals include the correspondence, essays and sermons, 1870-1917, of Calvin E. Amaron; the Bieler Family; J. Armitage Ewing (largely concerning the controversies surrounding Union in 1925); William Mair, sermons, 1827-1855; Richard Robinson, diaries, personal records, sermon outlines, 1857-1912; Henry Wilkes, 1822-1878, and others.

Gould's papers fall into two series. Family correspondence covers the years 1856 to 1860, when Joseph and his brother Charles were travelling in Europe, and consists of letters home from both young men, and their parents' replies. Manuscript music comprises two volumes of church anthems, with some organ music; some are original compositions by Gould and Samuel Warren. Related to this is Gould's brief manuscript account of the origin of the Mendelssohn Choir. Some family photographs are also included.

These papers contain Forbes' personal files of correspondence and clippings, some design materials and films of McGill football games. The personal files contain biographical materials such as his birth certificate, military commission and service records, and letters concerning his employment at McGill. Other files concern Forbes' designs for decorations for the 1951 Royal Visit, the McGill C.O.T.C., the Forbes Trophy for athletics, Forbes' involvement with McGill athletics and museums, and the career of his brother Kenneth Forbes, a painter. A number of diplomas and certificates awarded Forbes, as well as a photograph album, complete this series. Materials for designs include files on heraldry, a collection of illustrations from 19th century periodicals, designs for the Royal Visit decorations (a few, by Percy Nobbs, were used for the 1939 visit), maps, linocuts, bookplates, and programmes designed by Forbes for McGill events, ca 1925-1950. Thirty-four reels of motion picture film record McGill extramural football games (1947-1951). Films with sound track show the construction of the Currie gymnasium (1939-1940), and demonstrate the swimming techniques of Matt Mann. Additional biographical material is provided by obituary notices and letters of condolence to Mrs. Forbes, and by clippings of articles about Forbes.
