Below the Lower North Branch the river keeps the same 
general character though rapidly enlarging. It flows in 
a series of fine long stillwaters or quickwaters broken by 
occasional rips, between banks occasionally of meadow, 
though oftener of sand gravel or -sandstone rising at times to 
low cliffs, while w'ooded upland and open terrace succeed 
in a fine alternation that baffles attempts at description. All 
of this part of the river we found most attractive, though the 
troubles that low water may bring to the canoeman might 
give a different impression. Then gradually the country 
opens out, more intervale appears, the uppermost settlement 
is met, and the river enters a fine great open intervale-filled 
basin in which it receives Nevers and Prices Brooks; and 
here the upper section of the river may be considered to end. 
The large branches of this part of the river are known 
to me only at their mouths, and their representation on the 
map is the best I have been able to give from various sources 
of information. All of them take their rise on low minor 
watersheds of the Eastern Plain, which exhibit, apparently, 
all the distinctive aspects of that plain, — low swells of wooded 
upland separated by wide swamps, meadows and bogs, in 
which the streams wind sluggishly. I could not learn that 
any of the streams exhibit notable features, though a gulch is 
reported from Riders Brook, and springs of unusual size or 
mineral quality are said to occur at several places. Of course 
a great deal of lumbering has been done on all of these 
branches. 
The intervale-filled basin in which Nevers and Prices 
Brooks meet the main river is of great extent, too great 
indeed, as it seems, to have been formed as a result of 
simple erosion. Below, the river continues to wind in wide 
intervales of the typical elm-studded sort, all farmed and 
attractive, down to the bridge at the Petitcodiac Road. 
In this distance occurs one feature of very special interest, 
namely, just below the large island marked on the map the 
river becomes constricted by the presence of a rocky ledge 
which pushes out from the left or south bank. This ledge
