During the Northeast boundary dispute after the Treaty of Ghent (1814), maps detailed the American and British / Canadian perspectives. This manuscript map depicts "Part of Cornwall Island, Part of Bug Island," two islands in the St. Lawrence River. It references two 1817 camps on Bug Island, one for "Gen.Porter" and one for "Col. Ogilvy" — American commissioner General Peter B. Porter and British commissioner Colonel John Ogilvy—both appointed under the treaty's 6th and 7th Articles. It also marks an observatory and tavern at St. Regis village across the river.

As of the 21st century, Kawehno:ke (Cornwall Island) and St.Regis Island (Bug Island) are largely part of the Mohawk Council of Akwesasne reserve, which falls geographically across international and Canadian province borders. This map is part of a larger archive, the Thomas Barclay collection (Coll. 26).
