Dear Sir/

Since our arrival here, we have been
employed in duties tending to produce as accurate
maps as possible of the countries interior of Lake
Superior. The assitant has been laying down
(on sheets of cartridge? paper) the lines of the various
routes of the three summers past, that we may
be able to compare them at one view; and is
now commencing a sclection of the courses, by
the compass &c. My Business has been a fair
journal of the survey of last summer, and the
calculations of all the observations for latitude
longitude &c &c which I hope to finish about
the 20th of this month.
From the rough lines laid
down it appears the monument No 1 of the
north west corner of the Lake of the Woods, is
that which will be adopted, it is the most
southern of those monuments; and the arc
of a great circle passing thro any two given

points of the Lake of the Woods, will not be perceptibly
different from a right line.
If any thing necessary for your
voyage should occur to you, I shall be much
obliged to you to inform me of it, that I may
attend to it. Will not raisins, currants
hone &c &c be required. What wines, or other
liquors do you prefer; what quality & kind
of tea, coffee, chocolate &c &c. It is as easy
to procure and bring up the things that are agreeable
to you, as those things which may not be well
selected; for with all precautions, those distant
dreary, barren countries have unavoidable
privations enough. At the latter end
of February or beginning of March, I shall go to
Montreal to arrange with Mssrs. Ross and Pomain-
ville for every thing that is required for the voyage
& for the guides, boats and men to be engaged
and for these latter all? must be more active
than ever, on account of the demand for the
Hudson's Bay Company & for Captain Franklin.
This will give time for every thing to be completed

in good order, and enable us to set off as soon as
the navigation permits.

Your most obedient
and humble servant
David Thompson

His Majesty's Commissioner
&c &c &c

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.
