connected with the glacial period. Although the valley is 
obviously not post-glacial, nevertheless its sharpness of angle and 
evident newness seems to admit, in view of the softness of its 
rocks, of no greater age than the glacial epoch. The entire valley 
has the characters and the appearance of those parts of the Nepisi- 
guit, and of the Northwest Miramichi, whicn I have described 
in earlier notes as “inter-glacial/’ ( or perhaps one should sav, 
“sub-glacial”) valleys. I have no doubt these streams are all of 
the same origin, and all connected with glacial phenomena, and 
the determination of the exact origin of one will give the ex- 
planation of them all. lit is very likely that the damming of the 
old outlet through the Pokemouche, whether this was by glacial 
ice or solid drift, sent the waiters over the lowest point of the 
plateau to the southward, which point would naturally lie where 
streams on its northern and southern slopes approached one 
another at their heads. Thus it is very possible that the com- 
parativety straight reach of the Tracadie below Pokemouche 
Landing was originally the head of Red Pine Brook, for not only 
are they in a direct line, but, as Mr. O’Connor tells me, the source 
of Red Pine Brook is here within a mile of the Pokemouche. On 
the other hand the part of the Tracadie south of the highest part 
of the plateau, at least the part for a mile or two above Lord and 
Foy, was very probably in pre-glacial times simply a branch of 
the present lower Tracadie below Little South Branch, as was 
Lord and Foy itself. But more detailed study is needed to de- 
termine these interesting details. 
The Little South Branch also runs in a narrow valley, cut 
deeply into the plateau. Its direction continues that of the river 
below it, of which probably it is the morphological head. Below 
it the Tracadie valley down to the tide is very much wider than 
anywhere above, wide enough so that the river winds sinuously 
back and forth from wall to wall around great int:rvale points, 
the windings shown on the map being of this minor character 
and not major windings of the valley itself. But the valley wads 
are fairly steep '(aside from the places where the stream is 
obviously cutting into them and forming cliffs), and the plateau
