y this portion of the boundary as fixed by that treaty.

The south shore of Lake Pohenagamook forms an angle of about 100 deg. with
the direction of the stream which flows from it, and marks with great
certainty the point at which, according to the late treaty, the straight
line is to be commenced in running the boundary southwestward to the
Northwest Branch of the river St. John.

The work of this division was connected with that of Captain Talcott's
division of the preceding year by noting the position of a common point
on the western shore of Lake Pohenagamook near its head.

The commissioner and his party reached the Grand portage, or British
military road, where it crosses the river St. Francis on the 2d of
November, and connected their work with that of Professor Renwick's
division of the preceding year at the bridge near Fournier's house.

Observations were also made at this bridge for the latitude and
longitude, when the weather was favorable, between the nights of the
2d and 5th of November, and a connection was made in longitude with
the meridian of Quebec by comparisons of the local time with three
chronometers transported from the first to the last mentioned place
between the 6th and 10th of November.

This comparison was repeated on the return of the commissioner by
observing again at the St. Francis bridge before mentioned on the night
of the 10th of December, with the thermometer ranging during these
observations from 11 to 15 deg. below zero of Fahrenheit's scale, there
being then near 4 feet of snow upon the ground. The commissioner then
proceeded by the Grand portage road, and the road which pursues the
margin of Temiscouata Lake and the valleys of the Madawaska and St. John
rivers, to the mouth of Green River, where on the night of the 12th of
December he again observed at the same point where his observations of
the 29th of September were made while ascending the St. John. These
completed, he proceeded to the Grand Falls, and on the 14th of December
discharged his party, which terminated his field duties for the season.

The distance surveyed along the new line of boundary by this division
the past season is--

Miles.
1. Along the river St. John from the meridian of the
monument of the source of the St. Croix to the mouth
of the river St. Francis 71-1/2

2. Along the river St. F
