a mile below Stony Brook the river passes through an interesting- 
gorge, which appears not to be post-glacial, but probably belongs 
to the type described elsewhere as “ inter-glacial,” for, while it 
has vertical cliffs on both sides, the stream hows through it over 
drift, and its bed does not fill the gorge. Finally as the river 
nears the junction with Little River it is fiowing over a broad 
shoal bed with low banks, rising to occasional cliffs on one side 
or the other, through a country showing no hills above the vege- 
•tation of the banks. It now bears a remarkable resemblance to 
the part of the Xepisiguit between the Narrows and the Grand 
Falls, and probably has had a similar origin and history. This 
•character is preserved to the Tomogonops, a dark-colored stream 
from the northwest, or approaching which fertile intervales with 
some signs of cultivation begin to appear.* Here the river 
swings into what is obviously the Tomogonops valley, which it 
follows to Portage River, through a charming level country be- 
tween intervales and terraces. 
This part of the river is certainly puzzling physiographically. 
Its swing to the northeast when the general direction of the val- 
leys of this region would lead us to expect a southeast course, 
suggests that the part below Little River at least should be post- 
glacial. but it obviously is not. Its course from Little River to 
Tomogonops suggests that it may have had a pre-glacial outlet 
into the Xepisiguit by way of Portage River, and this may have 
been the case, unlikely as it seems. An objection to this is that 
the same explanation would seem to have to be given for the 
■direction of the South Branch Sevogle just above the Square 
Forks, and this is hardly at all probable. On the other hand this 
curious northeasterly turn is characteristic not only of this river 
and the South Branch Sevogle, already mentioned, but of other 
Tranches of the Miramichi, Dungarvon, Renous, Little Southwest, 
•etc. ( see map with Note 50), and of the Xepisiguit above Grand 
Falls, so that this change of direction of them all would seem to 
be due to a common cause. The Geological maps show th?t in 
general this common change of direction occurs just west of the 
line of Lower Carboniferous rocks, and hence it may in some way 
* The arranjjement of the rivers on the map suijgests that Little River may at one time 
have followed the brook emptying near Tomogonops.
