This fonds consists of copies of the certificates granted to William Vaughan as an engineer and for the inspection of the passenger riverboat "Exota", both issued by the Canadian Department of Marine and Fisheries.

It also consists of photographic copies of 61 technical drawings for small water craft and boats, including a 74 ft. dragger, designed by Vaughan, as well as photographic copies of 4 maps, including a detailed map of properties on Campobello Island. Also included are a handwritten biography of artist and historical illustrator C. W. Jefferys and a photocopy of a printed guide to hunters and anglers in Northumberland County. The latter copy is of poor quality.
