of the 48th parallel, in the eastern part of the slate, indications 
arc, that lignite beds arc quite abundant in Valley county as

The Mohawk Valley sections. — Since the preparation of the 
writer's sections in the Mohawk valley and Saratoga county* 
Messrs. J. M. Clarke and Charles Schuchert have proposed 
Lowville limestone for the Birdseye and used Lorraine beds in 
place of the Hudson Riverf and these names should be substi- 
tuted for the synonymous ones used in my sections Still later 
Dr. Clarke has proposed the name Little Falls dolomite for the 
Calcifermis of the Mohawk valley.:!: 
Professor Cushing has also fully described the crystalline 
pre-Cambrian rocks at Little Falls and shown them to be sy- 
enite cut by two diabase dikes. § From Trenton Falls south-
