Fonds consists primarily of textual records offering comprehensive coverage of the business dealings of the Russells: correspondence, legal documents including estate records, indentures, agreements, leases, wills, etc., financial records, fragments of flock and herd registers, and printed matter. Some of the aforementioned textual material relates to Wm. Russell Sr.; of particular value here are real property tax assessment certificates, which comment on various aspects of the life of the elder Russell. The fonds also includes 2 postcards, one unidentified and one of the Richmond Hill Methodist Church; and two photographs depicting, presumably, the Russells, [ca. 1880]. Also present are 3 architectural renderings, floor plans, elevations, mouldings and casements, of an unidentified residential structure, [ca. 1880]. A variety of richly-ornamented diplomas, certificates, and ribbons and Stevensgraphs reflecting victories by James and William Russell cattle at contests sponsored by the West Riding of York and Township of Vaughan Agricultural Societies, the Woodbridge Agricultural Society, the Toronto Industrial Exhibition, the Dominion of Canada Industrial Exhibition, and the World's Columbian Exposition in Chicago, covering the period 1874-1900 provide ample and colourful evidence of the skill of the Russell brothers in their particular sub-field of agricultural science.
