growth. Their aspect here is almost identically that of the raised 
bogs which have been described from other parts of New Brunswick.* 
At the lower margin they are most bog-like, some two feet thick, and 
they end downwards with an abrupt* rounded edge. Evidently the 
water in them settles to the lower edge, promoting the more vigorous 
growth there, and causing them to grow down the slopes. Such bogs 
demand much pure water for their growth, and the question now arises 
as the source of supply in this case. Two explanations appear possible. 
First, the bogs may have formed when the whole slope was heavily 
forested (as the many blackened stumps show that it was until 
recently), and since then they have managed to soak in enough water 
from the rains to keep them growing, the northern abrupt slope of the 
mountain protecting them from great evaporation. In this case they 
would simply be the remnants, rapidly disappearing, of once extensive 
bogs. Against this view, however, is the fact that such bogs do not 
appear to grow upon forested felsite hills in this region. I have been 
upon a number of them and have never seen such bogs Moreover, 
even if they are such remnants, it does not explain the source of the 
water sufficient to keep such extensive bogs supplied, for rain alone 
could scarcely do it in such a perfectly drained situation. The other 
explanation is that there is some peculiarity in the structure of this 
mountain which produces the storage of water under the rocks in 
spots, allowing it to escape gradually after the manner of springs. 
But no trace of such a structure is to be seen. The subject is very 
puzzling. 
43. — Evidences of the Sinking of the Coast of New Brunswick. 
Several of our writers on recent geology, notably Gesner, Matthew 
and Chalmers, have given evidence to show that the New Brunswick 
coast is sinking at several points. The following facts are of interest 
in this connection : 
In 1797 a very careful survey of Dochet Island was made by Thos. 
Wright, Surveyor-General of Prince Edward Island, in connection 
with the boundary controversies, and his map has recently been 
published.! One prominent and easily-recognized ledge has this
