every respect, except in its greater elevation, which, however, is^ 
readily explained by an upwarping of this region. Unlike the central 
Carboniferous plain, it does not slope off to the eastward, but holds its 
height to near the mouth of the Restigouche (if, indeed, it does not 
slope slightly thence to the westward), whence it falls ofip relatively 
rapidly to Bay Chaleur. Why, now, does this plateau not slope 
to the eastward when its contemporary, the Carboniferous plain, does 
so ! Here Daly’s suggestion as to warping about a hinge line extend- 
ing through Cape Sable, Digby, and east of St. John, is most import- 
ant. If, now, that line be continued in a northerly direction, it will 
pass over the eastern end of Grand Lake (through the highlands 
occupied by Marr’s and Emigrant Settlements),* through the highest 
part of the Central Highlands, and across the mouth of the Resti- 
gouche River, t This would represent an anticlinal uplift from which 
the old peneplain sloped on the one side to the eastward (thus explain- 
ing the slope of the Carboniferous plain), and on the other to the 
westward (thus explaining the lack of easterly slope in the Silurian 
plateau). But it explains many other facts as well, of which the most 
important are these, that the St. John has been turned south from 
its proper morphological course into Bay Chaleur, and that the Tobique 
runs southwest instead of northeast (Note 45) ; and further, that the 
St. John, after thus reaching the Carboniferous basin, does not follow' 
it to the sea, but continues southward into the Bay of Fundy. It 
perhaps explains also the turning of the Miramichi southward from its 
course into the Dungarvon to the Taxes, near Boiestown (Note 50). 
Such a syncline usually is accompanied by corresponding anticlines^ 
however, and one of these we doubtless have in the great trough 
occupied by Nepisiguit Bay, the Lower Nepisiguit, the north and 
south part of the Northwest Miramichi, and the right-angled bends of 
the main Southwest Miramichi. East of this appears to come another 
anticline, followed by a syncline, forming Northumberland Straits, 
while another anticline forms the higher lands of Prince Edward 
* Independently of Daly's suggestion as to the anticlinal hinge line, I had previously 
come to the conclusion that the ancient watershed east of the lower St. John was at the 
head of Grand Lake, that most of Salmon River formerly flowed into Richibucto (whose 
morphological head was Salmon Creek, west of the Gaspereau), and imich of the Canaan 
into the Buctouche (whose morphological head was Prices Brook), a subject to which I 
shall return in a future note. 
+ Possibly the south branch of Nepisiguit and the Upsalquitch may occupy the crest of 
this anticline.
