Surveyors working under the auspices of the 7th article of the treaty of Ghent created this manuscript map of a section of the northern boundary of Michigan, including Drummond Island and Lesser Manitou. This map is part of a larger archive, the Thomas Barclay collection (Coll. 26), related to the drawing of the Northeast boundary between British Canada and the United States.
