He then gives a brief of his proposed argument, indicating the 
points on which he afterwards based the British claim, as we shall 
see later. This letter, therefore, is a contemporary record of the 
genesis of the British claim to the Mars Hill highlands as a boundary, 
showing that it was formulated by Chipman (or rather by Chipman 
and his son of the same name, for they were joint agents for Great 
Britain in 1817 and 1818). Ward Chipman, sr., died in 1824, and his 
son continued as British agent to the end of the controversy. 
Bouchette’s and Johnson’s reports have been published in part in 
the “ Statement” of 1829, and the former in the Journaux du Conseil 
Leg. de Canada, 1844-45. 
The next year the exploratory north line was continued from the 
watershed between the Restigouche and the St. John by Mr. Johnson 
for the United States, and Mr. Odell, aided by Campbell, for Great 
Britain, and in September they reached the waters of Beaver Brook, 
a branch of the Metis and thus for the first time located the point at 
which the due north line from the source of the St. Croix meets the 
watershed south of the St. Lawrence. But this point of course did 
not fulfil the description given by the treaty to the north-west angle 
of Nova Scotia, for it separates the waters flowing into the River St. 
Lawrence from those falling into Bay Chaleur, and not into the At- 
lantic Ocean. The journal of this survey is preserved,’ and while of 
great local interest, and giving a vivid picture of the great difficulties of 
surveying in that wilderness country far from settlements and bases of 
supplies, contains nothing essential to our present subject. 
This survey had, however, a great influence upon the cartography 
of this region, for it gave the original for that section on all of the 
maps (for twenty years), down to the new survey made in 1842, as 
we shall later trace. Odell’s and Johnson’s Reports of this survey 
were published in Synopsis in the “Statement” of 1829, and Odell’s 
is given fully in the Journaux du Conseil Leg. de Canada, 1844-45. 
In the meantime the commissioners had reassembled May 15, 1818, 
at Burlington, Vt., and later in the month they met at Montreal and 
St. Regis. There was much delay in the completion of surveys, how- 
ever, on other parts of the boundary, and the commission did not meet 
again until May, 1819, but yet further delay being necessary it 
adjourned for a year, and again to November, 1820, when the Board met 
in New York, decided that no further surveys were necessary, and 
adjourned until May, 1821, to allow the agents time to prepare their 
memorials. The full accounts of these meetings are given by Moore.
