BrigEF DescrRIPTION OF THE REGION 
Stretching northward along the east side of the Quinnipiac 
River valley for fifteen or sixteen miles, almost the entire distance 
from New Haven to Meriden, Connecticut, is a narrow sand plain 
Or series of sand plains. Though perhaps once continuous, the 
area is now crossed by small streams which have cut their chan- 
nels through the sand. In some instances alluvium has been 
formed along the beds of these streams supporting a somewhat 
_ different class of plants than is found on the plains. In this way 
the area is divided transversely into a number of small plains.
