it at intervals of many miles
apart, is here exhibited through at least two-thirds of its extent in so
satisfactory a manner as in itself to preclude the idea of an "axis of
maximum elevation" composed of anything like a connected or continuous
chain in this region of country.

MAY 1 1842.]

In addition to the surveys upon the boundary line claimed by the United
States, an exploring line was run under the direction of Professor
Renwick, as is more particularly described in Appendix No. 1. This line
extended to an eminence on the eastern side of Lake Matapediac, elevated
1,743 feet above the level of the sea. The views obtained from this
eminence established the fact that a chain of highlands extended thence
to the north shore of the Bay des Chaleurs. They are believed to
terminate in an eminence, which from its imposing appearance has been
called by the Scotch settlers at its foot Ben Lomond. This was measured
during the operations of the summer of 1840, and found to rise from
the tide of the bay to the height of 1,024 feet. This exploring line,
coupled with the more accurate surveys, appears to establish the fact of
the existence of a continuous chain of eminences entitled to the epithet
of highlands from the north shore of the Bay des Chaleurs at its western
extremity to the sources of the Connecticut River. Returning from the
latter point, they exhibit the aspect of well-marked ranges of mountains
as far as the sources of the Metjarmette. Thence to the sources of the
Etchemin extends an undulating country whose mean height is 1,300 or
1,500 feet above the level of the sea. The boundary line is thence
prolonged to the Temiscouata portage over well-defined ridges to the
eastern side of Lake Temiscouata. At the sources of two of the streams
which run into this lake the minimum heights of 651 feet and 676 feet
have been observed.

With these exceptions, the sources of the streams which rise to the
north of the Temiscouata portage and between the lake of that name and
Lake Matapediac average more than 900 feet above the level of the sea.
For the purpose of describing this portion of the line claimed by the
United States, we may take this height of 900 feet as the elevation of
a horizontal plane or base. On this are raised knolls, eminences, and
short ridges whose heights above this assumed base vary from 300 to
1,300 feet. The more elevated of these are universally designated by the
hunters who occasionally visit the
