In obedience to the terms of the treaty, the undersigned met at Bangor, in the State of Maine, on the 1st day of May, 1843, where they produced and verified the authority under which they each were respectively to act.  They then adjourned, because the weather was not sufficiently open for taking the field, to the 1st of the following month (June), and agreed to meet again at that time at Houlton.

Accordingly, they did meet at that place, and began their operations.

It may be desirable to state at the outset that for the sake of convenience the whole line of boundary marked by the undersigned has been divided in the mention made of the different portions into the following grand divisions, viz: 

“North line,” from the source of the St. Croix to the intersection of the St. John.

“River St. John,” from the intersection of the north line to the mouth of the St. Francis.

“River St. Francis,” from its mouth to the outlet of Lake Pohenagamook.

“Southwest line,” from the outlet of Lake Pohenagamook to the Northwest Branch of the St. John.

“South line,” from the Northwest Branch to the parallel of latitude 46 deg. 25’ on the Southwest Branch.

“Southwest Branch,” from the parallel 46 deg. 25’ to its source.

“Highlands,” from the source of the Southwest Branch of the St. John to the source of Halls Stream.

“Halls Stream,” from its source to the intersection of the line of Valentine and Collins.

“West line,” from Halls Stream to the St. Lawrence near St. Regis, along the line of Valentine and Collins.

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.
