Contains one ledger book (cashbook), half-filled, for Blackwood who was a retailer in Montréal.

The collection contains materials related to a bicycle relay ride between Sarnia, Ontario, and Montreal, Quebec, held June 15-16, 1894 by the Canadian Wheelmen's Association (CWA) under its president, A. T. Lane, an early importer of bicycles to Canada who is credited by many contemporary sources as the first person to ride a high wheel bicycle in North America. The relay ride was organised as a promotional event for the CWA's annual meet, hosted in Montreal that year. The collection contains a newspaper article from the Toronto Mail (June 16, 1894) detailing the route and listing the participants, as well as a leather travel satchel used to carry a congratulatory letter to the president of the Canadian Wheelman's Association to be signed by the mayors of the cities and towns along the route. The satchel is embossed with the text: "Sarnia to Montreal relay ride, 1894." The collection also contains a published programme from the CWA annual meet, entitled, "Our city and our sports : souvenir and official programme of the 12th annual meet of the Canadian Wheelmen's Association, Montreal, July 1894."

Moshe Safdie's undergraduate thesis, "A Three-Dimensional Modular Building System," contains all of the concepts that would be realized in Habitat '67 at the World Exposition in Montreal. Officially titled "A Case for City Living," the thesis outlines Safdie's central premise: how can high-density urban housing include the amenities found in low-density suburban housing developments?

The building system developed in the thesis combines three distinct concepts: an integrated three-dimensional urban structure, a construction system based on three-dimensional modules or boxes, and a system adaptable to a wide range of site conditions. The thesis explores three possible construction systems, applied to a community of 5000, each with its own structural system and geometry. In the first system (single repetitive module), a structural frame supports non-load-bearing, factory-produced modular units. In the second system (bearing-wall construction), the same modules are assembled in a load-bearing arrangement. In the third system (load-bearing module), prefabricated walls are arranged in a crisscross pattern.

Overall the systems allow for flexibility, identity, privacy, community, and individual outdoor space. The modules may be stacked in many configurations to create a variety of housing types. The flexible arrangement allows for a complex in which no two dwellings are exactly alike and each can be recognized from the exterior. Because the modules are stacked on top of one another, walls and ceilings are doubled up, providing sound attenuation and privacy not achievable in conventional city-apartment high-rise construction. Modules are arranged in a staggered form, stepping back and allowing each roof to become an outdoor terrace for another dwelling. Pedestrian streets and vertical elevator and stair cores form the primary circulation systems. Finally, the modules are manufactured in a factory, lowering the individual-unit cost and allowing for relatively quick construction.

Consists of a statement from the Keerper of the Common Gaol of Montreal presented to the Grand Jury of the Court of Oyer & Terminer for the District of Montreal, 1821. The statement declares that the prison under itscurrent configuration is inadequate for the increasing number of prisoners that have been lodged therein rendering it almost impossible to separate different classes of prisoners. The Keeper, Peter Holt, requests that the lower part of the prison ought to be restored to its original use and reunited to the Common Gaol to create more space for prisoners.
