actor down to the u]:)permost old settlement a few miles above 
Ledbetters Brook. Farther downward the river becomes still 
larger, quieter, and more open, with the country gradually 
rising, although the valley of the river remains ever open, 
mature and trough-like. It is a decidedly pretty stream, though 
rather monotonously so, and the forests are everywhere un- 
broken and unburnt. And thus it continues down to the 
long deadwater made by the Blackville Dam and to the set- 
tlement, where the country rises gently some hundred feet 
abovT" the river. 
Summarizing the characteristics of the river as a whole, its 
most notable feature is its singular homogeneity of character, 
and its consequent lack of any striking features of any kind. 
It has a remarkably even slope, regularly decreasing from its 
source downward. 
We turn now to the probable physiographic evolution of 
the river. So scant is the relief of the country in which it 
Hows that it is impossible to tell from the river anything more 
than the maps suggest, and almost anything they suggest 
may be possible. Its parallelism with' the Main Southwest 
and the Dungarvon, between which it lies, implies, of course, 
a history identical with theirs as part of the remarkable North- 
umbrian system, already discussed in these Notes (No. 93). 
Its extremely wide open and mature-looking character, how- 
ever, suggests very strongly that it may once have been the 
outlet of a much larger river. And this fact correlates very 
well with the curious alignment of the stream with the Main 
Southwest Miramichi above Fall Brook, suggesting that it may 
once have been the outlet of some part or tributary of that 
river. Indeed, I think it not beyond possibility that Burnt 
Hill Brook may once have had a course l)y way of McBeans 
Brook and the lower part of Salmon Brook, into the south 
branch of Bartholomew, in which case the Clearwater may 
have flowed by way of Ciilman Brook and the present main 
river t(^ Fall Brook, and thence across to the North Branch 
or i)erha[)s the Dungarvon. Other possible connections, of 
minor importance, are suggested by the map, including a con-
