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.
