BULLETIN OF THE NATURAL HISTORY SOCIETY. 
The most interesting and most important fact brought out by the- 
measurements in the vicinity of Nictor Lake is that Mount Carleton 
is higher than Sagamook. In confirmation of the testimony of the 
aneroid measurements, I may add the following facts. Standing 
upon the highest point of Carleton one can look clear over the summit 
of Sagamook, and see the hills on the horizon beyond except in one 
small spot where they dip down below their average level ; but as 
seen from Sagamook, Carleton stands out against the sky without any- 
thing showing beyond, though the hills are higher to the south than 
to the north. Again, in order to settle their relative heights, I took 
with me a spirit-level and tripod. When set level on the summit of 
Carleton and sighted upon Sagamook, the horizontal line of sight 
passed clean over it ; when the same level was sighted from Sagamook 
upon Carleton, the horizontal line of sight struck Carleton considerably 
below its top. This evidence is conclusive as to the relative heights of 
the two.

As earlier pointed out (Note 26) we have in New Brunswick two 
good examples of great peneplains, the eastern Carboniferous plain 
and the Northern Silurian plateau. Peneplains frequently possess 
islands or remnants of the old materials left behind in the general 
planing down of the surface, and such islands are called monadnocks. 
Have our New Brunswick peneplains any monadnocks 1 When one 
stands upon the top of Bald Mountain (or Mount Champlain)* on the 
Kings-Queens boundary and looks off to the north-eastward, he will 
see what appears to be a very typical monadnock in the hill on which 
Marr Settlement is situated, which rises abruptly from the plain east 
of Grand Lake. It is not, however, a real monadnock, for, as Dr. 
Matthew informs me, though of Lower Carboniferous age, it is com- 
posed of a ridge of volcanic rocks, and hence remains, not because it 
is left behind in the general erosion, but because it resists erosion 
better than the surrounding rock. The larger elevation north of 
Grand Lake on which the Emigrant settlement stands is of similar 
nature. As to the Silurian plateau, there appears to be a typical 
monadnock in Green River Mountain, which stands up prominently
