Other sections show alternations of red and gray compact sandstones and red arenaceous 
shales, to the exclusion of limestones and marls, and, generally speaking, the limestones are 
not connected with extensive sections of sandstones. 
About three-quarters of a mile below the Springville Bridge, is an exposure of lime- 
stone (No. 5) quarried for building purposes. Here there are several thick beds of argilla- 
ceous and calcareous shales, gray and breaking into thin splinters, and enclosing beds of 
pale blue or gray argillaceous limestone. These beds are very hard and compact and, 
owing to the presence of thin layers of calcareous fireclay or shale, split readily into blocks 
six to twelve inches thick. Similar limestones of a darker blue color, occur on the West 
Branch, and have been used successfully for construction purposes. 
The measures referred to above are exposed in varying sequence in the river banks, 
as far as the forks, and preserve a general dip to the north and north-west, with frequent
