Mr. Charles John Sayer

I have to request of you
on behalf of Anthony Barclay Esqr. His Majestys Commissi-
oner under the 6th & 7th Articles of the Treaty of Ghent that
you will from this date to the month of next June 1823
use, and employ your knowledge of this country, and
of the Indian language, to obtain from the natives, every
Information possible of the headwaters of the Rivers that
fall into Lake Superior from the River St. Louis, to the Dog
River of Fort William, both inclusive. And also of the
situation of all the head waters of the various streams
that form the Rainy Lake River; from the most eastern
of those that form the new road from Fort William
to the most western that fall direct into the west side
of the Rainy Lake River. If any of the headwaters
of the Rivers that fall into Lake Superior, do not approach
within one mile of the headwaters of the streams, lakes
&c&c that at length form the Rainy Lake River, they
may be noticed merely as showing their respective
distances. But all those headwaters that are
within one mile of each other, as correct information
as possible must be obtained; and the nearer these
headwaters approach each other, the greater attention
must be paid to have the most accurate information
of their situation &c&c And it is particularly request-
ed, that the Indians draw with coal &c&c on birch
Rind, maps of the countries, rivers, lakes &c&c.
These maps you will be so good as bring out with you
to Fort William in the latter end of next May; when,
with an Indian Guide, you are requested to meet the
person employed on the survey, to act as interpreter-
Guide &c in conjunction with one, or more of the native

Indians. It is also particularly requested of you to in-
form yourself. If any lake between Lake Superior, and the
Lake of the Woods, is known to the natives by the name of
the Long Lake and if any lake is known to the natives by
the name of the Long Lake; inform yourself, and get a map
made, of its situation extne &c; and its connection with
the waters that fall into Lake Superior; or that flow into the
Lake of the Woods. And also note down the names
of all those old persons, who inform you, the Lake now
known to them by the name of the Long Lake was so cal-
led by the natives from their most early memory.
In consideration of these services, and those you have al-
ready rendered us, I shall apply to his majesty's Com-
missioners for a salary to remunerate you during the
time you are employed in the service of the Commission.
Your humble servant
David Thompson
Ast. Surveyor to the Board of
Commission under the 6 & 7 Art
of the Treaty of Ghent.

The above Mr. Charles Sayer, is a native, a son of a Mrs. Sayer
one of the first partners of the North West Coy. He was edu-
cated at Detroit; he then became a clerk to the North West
Coy. and for several years has had the charge of a trading
post in the countries between the Rainy Lake and the
NW Coast of Lake Superior at a salary of L150 pro ann.
The new order of affairs by the union of the two coys, reduces
the salaries of all the clerks, and he is one of several who have
refused to accept less. In this state he was recommended
to me, by his intelligence and education as the person best
adapted for the purpose of interpreter, guide &c &c.

To David Thompson Esqur
It was found that to transport Mr. Ferguson's provisions
and necessaries &c to Rainy Lake House, would require
five canoes, bsides his own canoe. Hence the freight
alone would have been 1727$.

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.
