To return to the narration of operations:
The exploring line of Colonel Bouchette and Mr. Johnson, as directed by the treaty, was traced from the monument at the source of the St. Croix to the intersection of the St. John.
The monument found at the source of the St. Croix, as described in the report of Colonel Bouchette and Mr. Johnson, and the course of their exploring line, was traced by blazes or marks upon the trees.
An old line, cut out by the assistant surveyors of Colonel Bouchette and Mr. Johnson, was also found, which terminated about half a mile north of the South Branch of the Meduxnikeag, where, by records to which the undersigned referred, they ascertained that it had been abandoned because of its deviation from the exploring line of Colonel Bouchette and Mr. Johnson.
After the exploration and re-marking of the north line it was cut out 30 feet wide. The same was afterwards done in all parts where the boundary passed through woodland. After thus opening the north line it was surveyed, and iron posts were erected at intervals to mark it.
The general bearing of the line was rather to the west of the meridian of the monument at the source of the St. Croix. The precise line laid down by the undersigned was determined by successive courses, of which each was made to be as long as was convenient, provided it did not pass out of the opening of 30 feet.
At each angle of deflection an iron monument was erected, and placed anglewise with the line. Other monuments were erected at the crossing of roads, rivers, and at every mile, commencing from the source of the St. Croix. Those which were not intended to mark angles of deflection were placed square with the line.
At the intersection of the St. John by the north line the river is deep and broad. The boundary runs up the middle of the channel of the river, as indicated by the maps, dividing the islands as follows:
