The fonds consists primarily of Logan's scientific work. A small percentage relates to the affairs of his family and to memorials to Logan after his death. The great majority of the papers consists of scientific correspondence from about 1820 to 1874, but mostly for the years following his appointment to the Survey in 1842. The letters deal with the collection, exchange and description of geological specimens, expeditions under the aegis of the survey, problems of research and scientific interpretation, scientific meetings, and visits by scientists. The number of correspondents, both individuals and learned societies, is very large, but the most substantial bodies of letters are from J.W. Dawson, geologist and Principal of McGill University, James Hall, paleontologist of the New York Geological Survey, Alexander Murray, Logan's chief assistant, and James Lowe of Grenville, Québec, who supplied Logan with specimens and appears to have been casually employed by him on surveying jobs and field trips. Other correspondents include Sanford Fleming, E.D. Ashe of the Québec Observatory, Thomas Sterry Hunt, and R.I. Murchison of the Geographical Society of Great Britain. Some letters pertain to political or social affairs, but usually in close connection with the scientific work of Logan or the Survey. These files contain copies of some of Logan's outgoing letters, as well as some letters addressed to other individuals, generally his assistants. Other scientific papers consist of field trip records (a journal kept during an expedition in 1845, a weather table kept on Lake Superior in the winter of 1846-1847, work records and astronomical readings for surveying projects, notes on mineral deposits, and lists of specimens), manuscripts of three scientific papers, as well as "Observations on the proposed Geological Survey", and manuscript and printed maps and geological schemata, including some by Logan of the Bay of Fundy, Labrador, and Hamilton, Ontario regions. Manuscript catalogues of specimens were prepared by Logan for the Paris Exhibitions of 1855 and 1867. Official reports include Logan's annual reports for 1842-1844, an overview of the work of the Geological Survey, 1866, two reports by Logan on prospects for mining on the north shore of Lake Superior, 1846, 1847, and one on mineral deposits around Rivière-du-Loup, 1853, as well as Logan's copy of his proposed Geological Survey Bill, 1844, and some copies of reports on mining and cartography prepared by others. Logan's financial records include expense accounts for Geological Survey expeditions, as well as other professional expenditures, such as books. His private and family life is reflected by a very brief diary of an Atlantic crossing in 1856, letters to and from his brothers James and Henry, his father, his uncle Hart Logan, and Hart Logan's partner John Fleming, covering the years 1772-1856. There are also baptismal and burial certificates, and legal documents, particularly bills of sale pertaining to James Logan's farm. Memorials to Logan after his death include J.W. Dawson's correspondence concerning the Logan Memorial Fund and Collection, 1881, and a manuscript biography by Alexander Murray. There is a chronological and author/recipient index to these papers.

Additional materials received from McGill Library's Rare Books and Special Collections consist of correspondence, 1837-1871; notices of admission to scientific and historical societies, 1842-1867; a history of the geological survey 1850; a report on mining locations addressed to B. Papineau, 1847; and correspondence with Robert Bell, 1861-1874.

Fonds reflects Jones’ work as a scientist, but not her activities as a poet. Over two-thirds of the materials are student notes coupled with quizzes, laboratories and reports. These largely stem from her Cornell period, and cover graduate seminars in population genetics and biochemistry as well as her doctoral research in plant breeding and plant physiology. There are also notes for courses on statistics, genetics, agriculture and animal physiology from the University of the West Indies.

Materials related to Jones' research comprise laboratory notes and graphs, drafts of papers and correspondence with publishers, scientific supply companies, and other scientists in her field. Administrative papers related to research include applications to the National Research Council, budget statements, requisitions and invoices for equipment, records of laboratory assistants and summer students, and correspondence on travel arrangements.

Her teaching of genetics and zoology is illustrated by her class and seminar notes, laboratory outlines, reading lists, and examinations. The administrative side is represented by memoranda on course changes and course evaluations, correspondence on the rental of films and the purchase of equipment, files on freshman counseling and the supervision of graduate students and letters of recommendation for students. Supplementing this are minutes of faculty meetings and materials relating to the McGill Association of University Teachers.

Biographical material on Jones may be found in a file containing curricula vitae, obituaries, and correspondence concerning the Barbara Jones Fund.

This file contains chapter two of a family history of Fairlie Candlish (1915-1948) written by his child.
