314 On the Geology of ihe Northwestern Regions of America. 
induced to undertake it in the belief that, in the absence of any 
general view of the geological structure of this extensive but 
interesting region, even the most cursory classification of its 
ormations might be useful to those employed in developing the 
structure of the crust of the earth,—the more especially as it is 
not probable that the attention of practical geologists will soon 
be directed to this distant and almost inaccessible field of inves- 
tigation. 
To render the present attempt as complete as the state of our 
knowledge will admit, I have carefully studied all the published 
documents and the geological collections relating to the subject 
to which I have been able to obtain access. And I have myself 
resided for many years in various parts of the territory, which 
may add, I have traversed from one extremity to the other,— 
from the borders of the United States to the Arctic Ocean in one 
direction, and from the frontiers of Russian America to Hudson’s 
Bay in the other. 
The titles of the publications.to which I have referred are in- 
dicated below, and may be considered as presenting a biblio- 
 pomtiag view of what is now of the geology of this part of 
Amer
