326 Messrs. Jackson and Alger on the 
Theories which are generally known and adopted, we have 
merely alluded to en passant ; but when appearances justified it, 
we have advanced opinions, some of which are perhaps novel, 
although they are the legitimate inferences from the facts discov- 
ered in our investigations, which were carefully made, and the 
results recorded on the spot where they were observed. Some 
errors will probably be found in our statements, such as must 
unavoidably occur in an account of the geology of an unexplored 
country, where there are but few of those conveniences, which 
abound in our own, to facilitate researches into its physical 
structure. In the main, however, we trust that they will be found 
correct, although some omissions will doubtless be discovered, and 
the boundaries of the rock formations may not always have 
been exactly portrayed. This was a necessary consequence 
of the obscurity occasioned by the uniform covering of soil which 
exists in the interior, and which, although it enriches the country 
in an agricultural point of view, greatly embarrasses researches 
into its geology. The sea-coast, denuded by the action of the 
waves, exhibits the most satisfactory views of its rock formations ; 
and when defeated in our search for the outcroppings of strata 
in the interior, we scarcely ever failed in obtaining a view of them 
somewhere along the extensive coast of the Province. The sim- 
plicity and remarkable regularity in geological structure exhibit- 
ed in Nova Scotia, cannot fail to excite the admiration of every 
Nova Scotia; although this mineral, accompanied by nearly the same substances 
that have been described in this paper, is abundant in the trap rocks of most other 
regions, and is never, we believe, wholly absent from any of them, when they occur 
to any considerable extent. And we are far from believing that it will not yet be 
met with when the rocks of Nova Scotia shall have been more minutely explored 
in search of it, and add another species to the interesting suite of substances which 
this country has already afforded.
