A mark was cut upon the stone, as indicated by the dot upon the meridian line above, from which these measurements were made. At Rouses Point a monument of wrought stone was set up at the intersection of the boundary by the meridian of the transit instrument used there by Major Graham, and an inscription was cut upon it stating the latitude and longitude, the names of the observer and his assistant, the names of the commissioners, and the territories divided. To mark the position of the instruments used at the following astronomical stations along the west line, two monuments within a few feet of each other have been erected at each station, and they have been placed on the boundary line due north or south of the instrument, as the case may have been. The stations are: Lake Memphremagog, Richford, John McCoy's, Trout River. The boundary along the west line, though very far from being a straight line, is generally about half a mile north of the true parallel of latitude 45° from Halls Stream to Rouses Point. At about 28 miles west of Rouses Point it, however, crosses that parallel to the south until it reaches Chateaugay River, where it bends northward, and, crossing the parallel again about 4 miles east of St. Regis, it strikes the St. Lawrence 151 feet north of 45°. At that point a large monument has been erected on the bank of the St. Lawrence. Two large monuments have also been erected, one on either side of the river Richelieu near Rouses Point. No marks of the old line were to be found about St. Regis. It was therefore agreed to run a line due west from the last blaze which should be found in the woods on the east side of St. Regis. That blaze occurred about 1 mile east of the St. Regis River. The maps, which exhibit the boundary on a scale of 4 inches to 1 statute mile, consist of 62 consecutive sheets of antiquarian paper as constructed by the British and of 61 as constructed by the American commission. A general map has also been constructed on a scale of 8 miles to 1 inch by the British and of 10 miles to 1 inch by the American commission, upon which the before-mentioned sheets are represented. The following portions of the boundary have been laid down by the British commission, on detached maps, on a scale of 12 inches to 1 mile, which have been signed by both commissioners: Grand Falls of the St. John, including the intersection of that river by the north line; islands of the St. John; the outlet of Lake Pohenagamook; the turning point of the boundary on the Northwest Branch of the St. John; the intersection of the Southwest Branch by the parallel of latitude 46° 25'; the source of the Southwest Branch; the source of Halls Stream; the intersection of Halls Stream by the west line; Rouses Point; St. Regis; Derby.
