Character of the Drainage 



The prevailing direction of streams within the state of Connecticut is 

 southerly to southeasterly, in general correspondence with the slope of 

 the Cretaceous plane of erosion. There are many small tributary streams 

 which have northerly courses, but the most notable exceptions to the 

 general rule are two streams which flow almost due north, and which, 

 though separated by a distance of less than 25 miles, bear each the name 

 Still river. The easternmost of these rivers is a tributary of the Farm- 

 ington, while the other flows into the Housatonic. The name Still river 

 is in both instances appropriate, for while the average fail of the normal 

 streams of the region for the first 15 miles in their courses is about 70 

 feet to the mile, the Still river which is tributary to the Farmington 

 falls but 100 feet in 10 miles, an average of 10 feet per mile, while that
