The fonds consists of a handwritten copy of the Engineer's (Mr. Tom S. Rubidge) report on the prospects for the development of the Trent Canal as an industrial navigation system linking Lakes Huron (through Georgian Bay) and Ontario. The fonds also includes comments on the state of repair of the existing locks, amount of work needed and estimated costs.

Fonds pertains to the work of Hazel Bird and her involvement with the Eastern Bluebird restoration project in Northumberland County. Included are 30 bird box observation journals, publications and newsletters of the Willow Beach Young Naturalists and the Willow Beach Field Naturalists, newspaper articles and information regarding the development of the bluebird project, statistical records, reports, and educational materials. The bird box observation journals also include notes about native flowers and other birds observed when checking the boxes. Also included are hundreds of letters which were sent to the Willow Beach Field Naturalists Club of Port Hope and to Bird requesting copies of the pattern and specifications of the bluebird nest box mentioned in two newspaper articles, Toronto Telegram, 14 May 1971 and Toronto Star, 19 September 1972; in these letters, many authors provide details of their experiences with bluebirds in various Ontario locations. Also included is a removable USB memory stick containing maps and lists which pertain to the locations of bluebird sightings/boxes referred to in the various statistical records and reports.
