Renwick.

The height of a part of the line explored by Captain Talcott in 1840,
lying at the source of Arnolds River, was not determined for the want of
a barometer.

Two or three miles in length of the line of highlands near the source of
the river Du Loup require to be reexamined.

The longitudes of Lake Megantic, Lake Etchemin, the source of the
Metjarmette, upon the line of Captain Talcott, and of some one point
on the line of Professor Renwick ought to be ascertained with greater
precision than the time that could be allowed during the last season
would permit.

The instructions of Mr. Forsyth contemplated an exploration of the
highlands described in the proclamation of 1763 as beginning on the
north shore of the Bay of Chaleurs. The existence of a continuous
elevated region from the tide of that bay to the termination of the
exploring meridian line has been ascertained in a manner satisfactory to
the commission, but the heights have not been measured on that part of
it which lies nearest to the Bay of Chaleurs.

Under these circumstances the undersigned are of opinion that as no
delay in the presentation of a final report will arise from further
explorations of the parts of the territory thus pointed out and the more
accurate examination of the uncertain matters, it would add to the
confidence which may be placed in their results that a party be employed
under the direction of each of the above-named commissioners upon the
said work. For this object it is estimated--

1. That $25,000 in all, say $12,500 to be expended under the direction
of each of the two above-named commissioners, will suffice. A less sum
than this will not keep two parties in the field during the working
season; a larger sum could not advantageously be expended on this part
of the work.

2. In estimating the amount necessary for completing the delineation of
the meridian of the source of the river St. Croix, it will be borne in
mind that numerous astronomical observations must be made in aid of the
operations with the transit instrument, in order constantly to preserve
the true north direction, a condition of the utmost consequence, not
alone as affecting the extent of territory that will be embraced by
it, but more particularly because the character and position of the
highlands alluded to in the treaty of 1783 would be exhibited in a very
different light as encountered by a line running _due north_, as is
required by the treaty, a
