[Ganona ] BOUNDARIES OF NEW BRUNSWICK 321 
In the meantime, however, although no further surveys were made 
along the north line, some others of interest to New Brunswick were 
made. In August Dr. Tiarks, the British astronomer, with Mr. Burn- 
ham, the American surveyor, were sent to examine the nature of the 
country where the principal rivers headed on the watershed. They 
ascended Green River, crossed to the Kedgewick, descended that river 
to the north line and proceeded along the latter to make sure that it 
reached waters of the Metis, returned to Green River and ascended its 
north-western branch and crossed to the lake named on our maps Lake 
Tiarks. Returning they ascended the Madawaska and examined the 
portages on the Touladi. Their maps are the originals for those 
regions for a long time thereafter. Tiarks’ report, of great local in- 
terest, is published in the “Statement” of 1829 and elsewhere. In 
these years many other explorations and surveys of great importance 
(of which a list is given by Moore, 7%) were made in central Maine, 
and on the headwaters of the St. John, which were thus mapped with 
approximate correctness for the first time. 
At various meetings in May, June, August and September the board 
met in New York, and as pointed out by Moore (76), their proceedings 
were not marked by that harmony which characterized the operations of 
the preceding commissions. There was much recrimination as to the 
causes of the delays in the completion of the surveys, which also had 
proven extremely expensive. The arguments of the commissioners were 
heard at these meetings, and wêre brought to a close on Oct. 4th (1821). 
The arguments of the agents are all preserved in the huge folio 
manuscript of which, as in the case of the documents of the other com- 
missions, several copies exist. They are in the form of opening argu- 
ments, second arguments, replies, observations upon replies, etc., etc. 
They are not however as voluminous as would naturally be expected in 
comparison with the records of the earlier commissions. It is needless 
to attempt to summarize the contents of these various documents indi- 
vidually, and I shall attempt rather to describe concisely the position 
of each of the agents. 
The British agent claimed that the north-west angle of Nova Scotia 
was at Mars Hill, where the due north line from the source of the St. 
Croix meets with a range of highlands running westward south of the 
Aroostook river, the continuation of a range which runs north-easterly 
to Bay Chaleur (see Map No. 30). This claim was not, however, 
entirely original with him, for a boundary on the highlands south of 
the St. John had been suggested in 1815 by Bouchette in his topogra- 
phical description of the Province of Lower Canada, where he advocates
