Anthony Barclay Esqr.
The express brought
your letter of the 10 April to me, on the 13th Instant
in the afternoon, at River St. Clair. At 3 1/2 Am we
set off and the same evening late arrived here.
On the 16th the Steam Boat arrived and in ?
Dr. Bigsby and the American surveying party
from the former I received your letters &c
which I have not time to answer, but shall
the very first leisure hours I get. On pursu-?
=sing the Resolutions of the Board of this year
I must confess I did not well? comprehend
them, until Mr. Bird explained them to me
by the conversatio he had heard, which is
also confirmed by Dr. Bigsby: from those
explanations the following Plan of operations
has been agreed on between Mr. Bird and my-
self. Myself and Son to continue our secti-
=ion //////// of the Survey of the Channels
(which 4 fine days will finish) and to ex-
=tend it up the River st. Clair, until the
Confiance shall heave in sight. Mr. Steven-
=son to continue his Survey to the Thames.

to my Base Line. mr. Bird and Party to commence
their side of Lake St. Clair, and follow up this
Survey upon the Plan proposed until it is
finished. When the Lake St. Clair & its Chan-
=nels, with the River St. Clair up to Lake Huron
shall have bec surveyed. mr. Bird and
the surveyors of both parties (myself & Son
excepted) go down to Point Pele to my Base
Line, and from thence finish that section
up to near Amherstburgh all which it is
supposed will be finished by middle of
July, provided the season is somewhat favor-
=able; they are then to make the best of their
way to Black Rock &c as soon as the confi-
=ance shall heave in sight. I shall go on
board her, and if I find she can be then im
mediately placed at my command, shall
with my son proceed directly to settle the
6 or 6 de? points in Lake Huron by astro-
=nomical observations - taking only two men
the Confiance
with me. But if the ^ must proceed down
to Fort Erie, I am then to take 6 men in the
Cutter, with my son, and directly proceed
to finish the business of lake Huron; by
which arrangement both parties, British
and American will be done at the same time
and probably at Fort Erie by that 1 August.

It is at the request of Mr. Bird, that I have
undertaken the whole of the required observa-
=tions of Lake Huron. The above arrangement
seems ? to be the Plan which will terminate
the Survey of the 6th Article in the least possible
time. Mr. Stevenson from bad weather,
I suppose, has not been fortunate in that part
of the survey allotted to him. Mr. Gibbs is just
so far recovered as to be able to go up to the
Camp and help forward the drawings back?
around take an active part. I am very
much obliged to yuo for the kindness and at-
=tention showed my son, I can assure ^ he has
been doing seven? severe? duty ; more so than any
draftsman has done before him; and I
consider the salary allowed hi sufficient.
We do not expect the ensuing summer
to be a season of good weather, but every
exertion will be made to close the Survey
of the 6th article as soon as possible, and bring
everything to the desired conclusion.
Your most Obedient
and very humble servant
David thompson

P.S. I have thankfully received my bills of
exchange for the 5th? April 1821 with the mag?
