Anthony Barclay and David Thompson created this double-sided rough manuscript map, part of an 8-map portfolio labeled "A" through "I," with detailed notes related to the drawing of the northern international boundary under the 7th article of the Treaty of Ghent (1814). This section is marked as "E," "Page 5 and Sheet No. 1" and the reverse "A," "Page 1. and Sheet No. 1."

Locations in this survey include the lakes and bodies of water between Northern Minnesota and Ontario.

Members of the British Commission included Anthony Barclay, David Thompson, and Samuel Thompson. Members of the American Commission were Peter B. Porter and William Bird. These items are part of a larger archive, the Thomas Barclay collection (Coll. 26).
