Pokemouche Landing- and Lord and Foy Brook, the river is run- 
ning at the bottom of a deep V-shaped vallley cut sharply into the 
surface of a very flat plateau. Nowhere in New Brunswick 
have I seen a valley so sharply cut into so level a country, features 
which can be plainly seen since the entire region is burnt to a 
barren. Below, the country falls off somewhat and the valley 
opens a little down to Lord and Foy Brook, which, itself in a 
similar deep valley, enters the main stream in a very pleasant} in- 
tervale basin. Below this stream the character of the river re- 
mains much the same, the plateau becoming slightly lower but 
the valley remaining narrow down to the Little South Branch, 
where the entire river swings abruptly to the eastward. Such a 
character for the valley suggests a rough river bed, which, how- 
ever does not occur. The flow is somewhat swifter than above, 
and a few small rocky rapids occur; but for the most part the 
river runs rippling over gravel or stones, or smoothly through 
swiftwater pools, a remarkably easy and very charming stream 
for the canoeman. This part of the river certainly has an at- 
tractiveness of its own, especially in the contrast of the pleasing 
stream and its dense margin of woods with the wildness of the 
great bare, steep, abruptly-winding rocky valley walls, sharply 
lined above by their angle with the plateau. But while the valley 
is narrow, the bed of the river, which is always over drift, never 
quite fills it, and narrow strips of alluvium occur on one side or 
the other, with considerable intervale points at the bends. 
We consider now the origin of this part of the river. Evident- 
ly it has cut directly across a plateau-ridge which is highest half 
way between Pokemouche Landing and Lord and Foy; and this 
ridge, I take it, extends southwestward with the sources of the 
Tabusintac upon its southern slope, and northeastward between 
the Pokemouche and Little Tracadie, reaching the sea at the up- 
land Green Point, and extending beyond to form the islands of 
Shippegan and Miscou. It is thus one of the ancient ridges sep- 
arating the Pokemouchian and the Tracadian Valleys of the 
original Northumbrian system of rivers (Note 93). But what 
sent the Tracadie across this ridge? It was, I think, changes
