his opinion on the north west Corner of the Lake of the Woods,
-that the Northwest side of the Lake of the Woods being laid
down on a Map in strict geographic position, there, that
convex curve, or Bay of water, which shall be found to
combine in its position, the greatest Longitude, with the
highest latitude; in the north west Corner or angle of the
said Lake.And the angular curve or curves, of the
Lake, on which this north west Point is most likely to
be found, can be determined in geographical position
by no other means than astronomical observations
for latitude and longitude. --For the northwest
angle of the Lake, is a geographical point, deducible
only from its geographical position on the globe.

Lake, let a line be drawn due south, until it intersects
a line drawn due east from the extreme west point of
the Lake; we have then a parallel of Latitude ap-
-plicable to the north western Point and a Meridian
applicable t the extreme north point. Then from this
parallel of latitude and meridian determine which of the
angles, or Bays, of the Lake; combines in its geographi-
-cal Position, the greatest west Longitude with the highest
north latitude, and this angle of the Lake will be
its most north western corner.--

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.
