of the owners were ascertained to
reside on the United States side of the river.

Monuments were erected upon the islands, marking them for Great Britain
or the United States, as the case may have been.

After leaving the St. John the boundary enters the St. Francis, dividing
the islands at the mouth of that river in the manner shown in the maps.
It then runs up the St. Francis, through the middle of the lakes upon
it, to the outlet of Lake Pohenagamook, the third large lake from the
mouth of the river. At the outlet a large monument has been erected.

In order to determine the point on the Northwest Branch to which the
treaty directed that a straight line should be run from the outlet of
Lake Pohenagamook, a survey of that stream was made, and also of the
main St. John in the neighborhood of the mouth of the Northwest Branch,
and a line was cut between the St. John and the point on the Northwest
Branch ascertained by the survey to be 10 miles in the nearest direction
from it, and the distance was afterwards verified by chaining.

It was ascertained also, in accordance with the provisions of the
treaty, by a triangulation of the country toward the highlands dividing
the waters of the St. Lawrence and of the St. John, that more than 7
miles intervened between the point selected on the Northwest Branch and
the crest of the dividing ridge. A large iron monument was afterwards
erected on the point thus selected, and the space around was cleared and
sown with grass seed. It is a short distance below the outlet of Lake
Ishaganalshegeck.

The outlet of Lake Pohenagamook and the point on the Northwest Branch
designated by the treaty having been thus ascertained and marked, in the
spring of 1844 a straight line was run between them. Along that line,
which passes entirely through forest, monuments were erected at every
mile, at the crossings of the principal streams and rivers, and at the
tops of those hills where a transit instrument had been set up to test
the straightness of the line.

As soon as the parallel of latitude 46 deg. 25' had been determined on the
Southwest Branch, in the early part of the summer of 1844, a straight
line was drawn from the boundary point on the Northwest Branch to a
large monument erected on the left bank of the Southwest Branch where it
is intersected by the parallel of latitude 46 deg. 25'. The line so drawn
crosses the Southwest Branch once before it reaches the parallel of
latitude 46 deg
