It Hows southeast to join other branches, as shown by the map, 
the waters meeting in a large open pleasant basin. Thence the 
united stream flows southward, at first very gently over gravel, 
then more swiftly, until it soon comes to cut into a pre-glacial 
schistose and granite floor.* * Meantime the hills close in upon 
the river in a way 'to show that it is here cutting into a mass of 
highlands. Downward the valley is deep, narrow and rough, 
with occasional falls over granite, — evidently a pre-glacial but 
otherwise comparatively new valley. Thus it continues down 
towards the junction with the South Branch, where the country 
opens out somewhat and the hills are apparently a little lower. 
The South Branch, at the junction well-nigh as large as the main 
stream, gathers ample waters from the westward, as shown by 
the map. The southern waters of this Branch lie in another 
large basin, which lies so nearly in a line with the great basin 
at the sources of Burnt Hill and Clearwater in one direction, and 
with the McKeel Brook Basin in the other, as to suggest that 
they all occupy another great north and south structural valley, 
homologous with that of the North Branch. Below the junction 
of the two streams I have not seen the river except at the mouth, 
but I am told that it is continuously swift and broken, though 
without any high falls, and flows through a country continuously 
lofty on both sides. Its principal branch in this part comes from 
Beaver Brook Lake, a very pretty lake with highlands immediate- 
ly on the north but lower country on the south. At its mouth 
this Branch is narrow and rough, and the valley appears com- 
paratively new. 
shown on Allen’s map of 1831, and is of course named descriptively for the great 
burnt hill on the east side of its lower course. Its mouth was visited by Charles 
Robb in his geological journeys as recorded in the Geological Report for 1866-69 ; 
and in 1899, as he informs me, Mr. W. J. Wilson, of the Geological Survey, 
traversed the portage road and made the observations recorded in Chalmers’ 
Geological Report for 1902, and shown upon his Surface Geology map. A very 
interesting account of a trip up this river is given by Edward Jack in Acadiensis, 
V, 116. But further than these, no references to the stream occur, so far as I 
can find, in either scientific or sporting literature. 
* As to the rocks in this vicinity, I have noted schists, granites, felspathic 
granites, schists and veins of granite, all within a limited distance, a mixture 
recalling that described in Note No. 88.
