Dear Sir
We have at length closed the calculations
for the maps of the survey of last year, and are now em-
-ployed in the fair maps.One 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, on the scale of
6 inches to one degree of Longitude, 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
47º-52 h to 49º-50 north and from Longitude 89º-45h
to 95º west. and even this scale is too small to clearly
represent the Brooks, small Lakes, Islands &c &c, thro’
and along which, we pass.I expect by the 15th
March, please God, to forward to Mr Ross for you, a
fair map of the interior Country on the above Scale.
And as soon after as possible, a map of Lake Superior
&c&c.I should be happ to learn your opinion
of the Survey for the following Summer, as without
it, I am at a loss how to act, not having heard from
you since last October, and Mr Hale has wrote me for
an Estimate for the ensuing Season &c
My last Letter was under fate of the 6 Febry
which inclosed my receipt for the quarter ending
end p1
begin p2
April 5th. Duplicates of which Receipt are now also sent.
The Snow is uncommonly deep the weather unusually
severe, and no appearance of Spring.
Your most Obedient
and humble Servant
David Thompson

Anthony Barclay, Esq.

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.
