With the Seseptioh of the reduction of this in the Atlas, it is 
believed that no geological map has appeared which presents to 
the student a connected view of so great an area of the continent. 
It extends from the Cretaceous and Tertiary rocks of New Jersey, 
to those of Nebraska and Dakota, and shows = a glance by far 
the greater part of the wide paleozoic basin of North America. It

On the other hand, we cannot fail to be struck with the extent of 
the Acadian coal basin, including large portions of Nova Scotia, 
and New Brunswick, and part of Newfoundland, Out of it, in 
fact, the Gulf of St. Lawrence has been excavated; and this wide 
maritime area, with its thick seams of superior ituminous coal, con-
