[GANONG] BOUNDARIES OF NEW BRUNSWICK 273 
evidently he made no survey in Passamaquoddy. He marks, however, 
Passamaquadi, which he appears to apply to the West Passage (be- 
tween Campobello and Maine) and east of this he places simpiy the 
inscription Mouth of St. Croix River. Now the position of this in- 
scription, together with the fact that no mouth of a river is shown, 
seems to make it clear that it refers simply to the region,— that in 
that vicinity lay the mouth of the St. Croix, and no particular river 
is intended to be designated. Southack seems to have taken the region 
from Point Lepro to St. Croix from this map (compare the two Nos. 23 
and 26), and finding a passage resembling as it does the mouth of a 
large river, where the name Mouth of the St. Croix River occurs on 
Blackmore, he naturally applied the name to the passage as on his 
map. Or, it is possible that both he and Blackmore took the St. Croix 
from a common source, which may even have been the supposed South- 
ack map of earlier date, (given in these Transactions, first series, Vol. 
IX, Section ii., 72) in which St. Croix indicates simply a locality, not a 
particular river. 
However this may be, it seems clear that on Mitchell’s map 
the source and course of his River St. Croix is that of the present river 
of that name, while its mouth is erroneously placed at a spot which 
is really the present Letete passage. No part of Mitchell’s St. Croix 
can represent any part of the Magaguadavic, therefore, while most of 
it does represent the Scoodic or present St. Croix. This is a very 
satisfactory solution of the problem, for it tends to show that not 
only did the commissioners of 1798 chose the correct river as the St. 
Croix as meant by the treaty, but that they also chose the St. Croix 
represented upon Mitchell’s map. This should remove every vestige of 
support for the claim still made by writers on the United States side 
of these questions,’ that the Magaguadavic should have been chosen, 
just as the testimony of comparative cartography and topography re- 
moves the support from the writers on the British side, that the west- 
ern branch of the Scoodic should have been chosen. As a whole, 
therefore, the decision of this commission seems to me to have been 
in every particular in accord with the true merits of the case, and each 
nation received its precise dues. The St. Croix Commission of 1798 

1 Thus Washburn takes this extreme view in his work in Collections of 
the Maine Historical Society, VIII. ; so does Winsor, in America VII. 173, 
where he says, ‘If the testimony of Mitchell’s Map was worth anything, 
there was no question that the easterly or Magaguadavie river (Mitchell’s St. 
Croix) was the river intended by the treaty.” Kilby in his ‘‘ Eastport and 
Passamaquoddy,” takes the same view, and it is re-affirmed in the Collections 
of the Maine Historical Society (Series 2, I., 189), and it is repeated by Men- 
denhall in his ‘ Twenty Unsettled Miles of the Northeastern Boundary.” John 
Adams held this view also in 1784 (page 246).
