Thirty-three of these points have been used in the correction of the paced and estimated distances.
Tables exhibiting these observations, their calculation and results, will accompany the detailed maps.
With a view to facilitate the operations of the joint commission it was conceived to be important that the intersection of the parallel of 46° 25' with the Southwest Branch should be ascertained, as also the point on the Northwest Branch (10 miles from the main St. John) where the boundary line from the outlet of Lake Pohenagamook intersects the said branch.
It is believed that these points are projected on the map which accompanies this report so near to their true position that the line indicating the boundary as drawn on the map may be considered to substantially exhibit the division of territory as effected by the late treaty.
The more thorough knowledge acquired through these explorations of the character of the territory which has been relinquished by the United States fully confirms the opinion previously entertained of its little value, either for its timber growth or for purposes of agriculture.
Bordering on the "Big Black" and "Little Black" rivers the growth of pine is large and apparently of good quality, and it is believed that most of the smaller streams falling into the St. John below the "Seven Islands" will be found fringed with pine, but it is quite certain that very little will be found included between the lines of boundary and the highlands as claimed by the United States to the westward of St. Francis River.
The office work of this party is nearly completed, all the calculations arising from the astronomical observations have been made, and the detailed maps (five in number) drawn to the scale of 1:50,000 (or nearly 1-1/4 inches to 1 mile), exhibiting the result of the surveys in 1840, 1841, and 1842, are in such a state of forwardness as to insure their completion by the middle of February.
These explorations and surveys embrace—
1. The highlands as claimed by the United States, extending from the northwesternmost head of the Connecticut River to the portage road which leads from the St. Lawrence River to Lake Temiscouata.
2. The highlands as claimed by Great Britain from the Metjarmette portage to the source of the Aroostook River.
