boundary
line had before the orders of recall reached them successfully
accomplished that duty, having connected their survey with points in the
survey of the previous year and thoroughly explored the culminating
points of the valley of Rimouski. As had been anticipated from the level
of the streams seen in 1841, this portion of the boundary claimed by the
United States is more elevated than any other portion of that line
between the Temiscouata portage and the northwest angle of Nova Scotia.
This survey would therefore have added an important link to the argument
of the United States had not the question been settled by treaty.

The party having received its orders of recall, all the articles of
equipment which could not be carried in the boats which had been
launched on the waters of the Restigouche were transported to the other
end of the portage and embarked in pirogues sent up Green River for that
purpose under the direction of the assistant commissary. The engineers
then set out on their return by the Bell Kedgwick, the Grande Fourche,
and the Southwest Branch of Restigouche. Ascending the latter stream,
this party reached the Wagansis portage on the 21st August, and arrived
at the Grand Falls on the 25th August.

The descent of the Bell Kedgwick was attended with great difficulties
in consequence of the low state of the waters. Until its junction with
Katawamkedgwick, to form the Grande Fourche of Restigouche, it was
necessary to drag the boats by hand.

10. The detailed map of the surveys of this division, exhibiting the
more important points whose altitudes were determined by the barometer,
has already been lodged in the Department of State under date of 27th
December.

Although the interest of this survey to the United States has now passed
away, yet, as it is probable that many years may elapse before this
country shall be again explored, and as it may still possess some
interest to the nation into whose undisputed possession it has now
fallen, it may not be improper to state the methods employed in the
survey, for the purpose of showing to what degree of faith it is
entitled.

The latitude and longitude of the mouth of Green River were furnished by
Major Graham. The three portages on that river were surveyed by chain
and compass. The courses on the navigable parts of the river were taken
with a compass and the distances measured by a micrometrical telescope
by Ertil, of Munich. This instrument, which
