NATURAL HISTORY AND PHYSIOGRAPHY OF NEW BRUNSWICK. 337 
in New Brunswick. They are of all sizes and depths, from a 
few yards in diameter and depth up to considerable basins ; some 
are wooded in the bottom, others are open meadow, others are 
bare rocks, showing evidence that they are lakes for a part of 
the year, while others are permanent and pretty little lakes. No 
doubt they are much more numerous than the dozen or more 
which we saw and whose general positions are shown on the map. 
This part of the basin appears to contain a series of parallel 
northwest and southeast moraines extending out from the west- 
ern plateau, whose directions determine the courses of the brooks, 
which turn around their eastern ends into Gover Lake. The 
entire region exhibits glacial phenomena in great perfection, in- 
cluding the irregular moraines of Upper Graham Plains and the 
glacial gorge of Patchel Brook, earlier described (Notes 63, 64), 
the remarkable drumlin hills and islands of Mitchell Lake present- 
ly to be noticed, and the parallel moraines, the sink holes and 
other phenomena of this basin. 
The main stream below Gover Lake flows southeast in a val- 
ley between a high and finely curved ridge (Gover Mountain) 
on the west and a lower ridge on the east, and, falling a few feet 
over boulders, with a possible granite ledge in one place, enters 
the first of a long series of lake-like deadwaters separated by 
short abrupt boulder rips. These deadwaters have the boulderv 
and boggy shores, irregular depths, and other characteristics of 
true glacial lakes, which indeed they are, of the simplest type. 
Into the second of these enters the outlet of Mitchell Lake. 
Mitchell Lake, 1366 feet above the sea, is another very attrac- 
tive lake of marked individuality. It is notably irregular in out- 
line, with many islands and peninsulas, with abrupt low hills 
near it and loftier ridges and hills in the background. It exhibits 
one especially interesting feature, in which respect it surpasses 
all other New Brunswick lakes, namely, the islands, peninsulas 
and the abrupt rounded hills of the shores are all beautifully 
rounded glacial knolls of the drumlin type. Further, the distinct- 
ness and attractiveness of these knolls are greatly enhanced by 
the fact that they are in considerable part bare of forest, and 
covered only with a carpet of heaths, allowing their contours to
