the northern part of the New Haven region. Even West 
miver was a stream of more power. In view of the relation 
m drainage areas and slope, I am led to conclude that the en- 
ergy or effective force of these streams, the Quinnipiac, West 
River and Mill River, may be approximately represented by _ 
the ratio 1: 4:95, 
The slope of the land was probably less than now through a 
change of level, as deduced in a former paper; but any dimi- 
hution of slope would increase, not diminish the contrast; for 
2 feet less would be a large deduction from 34 feet, but from 
9 or 29 very small.
