The result of these explorations may be stated as follows:
About 160 miles of country along or near the "_height of land_" have
been traversed, the traveled distances carefully estimated, and the
courses measured with a compass. Barometrical observations were made
as often as necessary for giving a profile of the route from the head
of Halls Stream to Arnold or the Chaudiere River, and thence to Lake
Magaumac via the corner of the State of New Hampshire. Some further
barometrical observations were made between the lake and the Kennebec
road, but for a portion of that distance the barometer was unserviceable
in consequence of air having entered the tube. Astronomical observations
were made as often as there was an opportunity, but, owing to the
prevalence of clouds, not as often as was desirable. They will serve for
correcting the courses and estimated distances traveled. Barometrical
observations for comparison were made at the intersection of the
Kennebec road and height of land hourly from 7 a.
