Dear Sir
We have at length closed the calculations
for the Maps of the Survey of last year, and are now em-
-ployed on the four Maps. -Onne Sheet of Antigua
-rian Paper of 52 Inches by 30 Inches, just contains The
Survey of Lake Superior, and of the interior Countries
so far as we proceeded last Summer, which is about 9 In-
ches to one degree of Latitude. - Distinct Maps
of the Survey of the interior Country, are also in hand
of 30 Inches to one degree of Longitude; which is three
fourths of an Inch to one geographical Mile.
If we consider the interior Country to the North West
Corner of the Lake of the Woods, to form only one Map
on this Scale; it will be, 7 feet in height by 14 feet in
width, containing an extent of Country from Latitude
Admin/Biographical History This compiled collection includes papers from Thomas Barclay (1753-1830), his son, Anthony Barclay (1792-1877), John Ogilvy (d. 1819), Ward Chipman (1754-1824), Ward Chipman, [Jr.] (1787-1851), David Thompson (1770-1857), Alexander Wadsworth Longfellow (1814-1901) and others related to the determination of the boundary between Canada and the United States. Materials include government documents, correspondence, maps, surveys, diaries and Indian deeds related to the determination of the boundary between Canada and the United States, particularly of the years of the St. Croix Commission, 1796-1812, the Commissions appointed after the Treaty of Ghent, 1814-1838, and the Commissions under the Treaty of Washington, 1842. Papers of diplomats appointed by the British and American governments include the correspondence of explorers who surveyed the boundary zones and of several other diplomats, political officers and aids who became involved in the arbitration of the border. The explorations around the Island of St. Croix by Robert Pagan and Native American Francis Joseph Neptune, and a map by Chief Wasp of the Ojibway tribe in the vicinity of Ontario and Minnesota are noteworthy.
