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.

Most of this archive documents the High School for Girls. The administrative records comprise prospecti for both High Schools, registers of attendance, 1875-1896, examinations, 1855-1858, 1884-1888, fees, 1863-1869, and corporal punishment, 1892-1896, 1949-1960, and memoranda from the Rector applying to either the boys' division or to both High Schools, 1897-1904. There are also working notes for teachers, 1902-1903, 1921-1931, and scrapbooks of programmes, clippings and notes concerning activities in both schools, covering the years 1913 to 1960. Examination papers, 1872-1882, a guest book, 1919-1943, an annotated address book of High School for Girls staff prepared by Principal L.M. Hendrie, 1911-1945, and photographic portraits of the Principals of the High School for Girls round out this series. Student activities are reflected not only in the official scrapbooks, but also in minute books, photograph albums and scrapbooks of the High School for Girls' Athletic Association, 1912-1913, Literary and Debating Society, 1906-1908, and English Club, 1935-1940. There are a large number of photographs of girls' sports teams, 1915-1941, as well as a scrapbook of clippings on the activity of High School for Girls Alumnae, 1953-1956.

The collection documents the involvement of McGill faculty, students, alumni, and staff during the Second World War. It contains information on 5568 men and women on active service, including 295 women. It also provides information on the 298 dead, 52 prisoners of war, and 629 recipients of medals.

The greater portion consists of folders, index cards, newspaper clippings, correspondence, and photographs of individual soldiers and civilians. Index cards, documents and photographs were created and accumulated by Fetherstonhaugh and placed in alphabetical order within specific categories. The collection contains four distinct series: index cards; textual documents, including newspaper clippings; correspondence and articles arranged by subject; and photographs. The first series contains subseries reflecting Fetherstonhaugh’s original subdivision categories.

The index cards are arranged in the following groupings:

-Subversive activities
-Killed
-Prisoners of war
-University staff
-Macdonald College
-Army course
-COTC
-US
-General list A-H
-General list I-Mc
-General list M-Z
-Returned from active service
-Photos in extension file
-Photos on loan
-Women
-Civil

Other files in the collection include correspondence and newspaper clippings arranged by particular subjects; correspondence and newspaper clippings concerning the McGill War Memorial Campaign, 1947-1949; Fetherstonhaugh's account book of income and expenditures, and some vouchers, 1942-1946; McGill News articles, 1942-1946; correspondence, memoranda, invoices, reviews, and newspaper clippings, 1947-1948, concerning the book McGill University at War, 1914-1918; 1939-1945.

Andreassen's papers fall into three series: personal materials, diaries, and professional files. Personal materials include family correspondence, 1929-ca 1932, and ca 30 cm of class notes and draft papers stemming from his student years, largely at Louisiana State. There are also files of private correspondence, some addressed to Mrs Andreassen, from the period 1975-1980. Andreassen's diaries cover the years 1936-1940, 1945-1952, 1962-1965, and 1968-1976. They record the working day and are interleaved with memoranda and correspondence, often of a personal nature. Professional files vary in nature with each stage of Andreassen's career, but correspondence and reports are consistent elements. To these may be added copies of surveys and inventories of the Louisiana Historical Records Survey, expense accounts and photographs arising from his work for UNRRA, records of archival deposits and drafts on an institutional history prepared as Archivist of CNR, and annual reports written as McGill Archivist.

Very few of the McLeod papers actually concern the Observatory. However, his work for the railways and in Newfoundland is documented, as are his views on the education and employment of engineers. The basic record for the early part of his career is a diary kept from 1870 to 1875, regarding student days and early work on the Observatory. An essay, "Winter under canvas" (1868) describes an early surveying job, and a letter from his father (1872) inquires about his academic progress. His work for the railways is documented by three letters of recommendation, and two letters (one from Stanford Fleming) on the work of his colleagues in the West. The Newfoundland survey (1875) is described in McLeod's diary, a manuscript essay "Across Newfoundland" (1876), his printed reports and three letters. His work at McGill is represented by six letters (largely official acknowledgements of appointments), and McLeod's manuscript notes on McGill history. McLeod's concern with the engineering profession is reflected in two addresses on education and professional development, and copies of about a dozen letters to Sir Wilfrid Laurier (1906-1908), C.A. McGrath and E.F. Wurtele (1912), largely on the employment of engineers in the civil service.

The fonds consist of draft reports and texts of speeches given by Vincent de Pasciuto-Ponte as well as bound reports and promotional material related to projects that Ponte was involved in through his work with architect I.M. Pei including McGill College Avenue and Place Ville Marie in Montreal, Quebec. In addition, the fonds contains published materials such as periodicals related to art and architecture, maps, travel literature and guidebooks (mostly relating to travel to Rome, Italy). Six black and white photographs of Ponte are included.
