NATURAL HISTORY AND PHYSIOGRAPHY OF NEW BRUNSWICK 341 
country is so heavily buried in drift and covered by forest that 
extremely few rock exposures were seen. On Patchel Brook 
granite and felsite both appear (Note 63), while on Upper 
Graham Plains there are considerable ledges of schist. The 
upper valley of the eastern branch of Patchel Brook has cut 
deeply into schists, and the stream at the head of the MacDougal 
Lakes has cut into granite. No other exposures were found, 
except a doubtful ledge of granite below Gover Lake, until the 
lower course of the river was reached, when ledges of schist and 
granite were passed, as noted on the map. The distribution of 
rocks shown by these, with some other, facts will be considered 
in the next note. 
The vegetation of the region presents no features of especial 
interest. It is all heavily forested, with the exception of three 
great open areas, the Upper Graham Plains, Lower Graham 
Plains, and the Mitchell Plains, all of which have been 
opened by early fires, and now bear the plants of open dry bar- 
rens. In places, especially along the river below the Mitchell 
Lake outlet, these barrens are growing up to forest, the two 
characteristic trees being the Princes Pine (P. Banksiana) and 
the American Larch (L. Americana). The forest on the ridges 
is the usual mixed growth of the typical New Brunswick forest 
type, including some good pine and spruce, while on the lower 
levels and around the lakes and deadwaters it is chiefly of the 
worthless black spruce-heath-hypnum type, characteristic every- 
where of granite boulder districts. 
The region is extremely rich in big game, especially in moose, 
caribou and deer. Beaver are also abundant, and are building 
new dams and other extensive work at several points, notably at 
the inlet of Hough Lake, and at the inlet of the eastern 
end of Dunn Lake. Probably in no part of New Brunswick are 
the large animals so abundant and so little disturbed.
