Such is the dramatic history, in epitome, of the glacial waters in cen- 

 tral New York. The remainder of this pa-peris n)ainly a record of theoij- 

 served facts, with only as much statement of theory and interpretation as 

 is necessary to show the significance and relationship of the i)henomena.

Tonawanda Valley 



Below Attica, or northward, toward Batavia the valle}' bottom is a 

 l)road })lain with low walls, declining 100 feet in the 10 miles to Batavia. 

 Southward the valley is narrow, with high steep borders, like the other 

 north and south valleys of western and central New York. Up the val-

 visible near stream deltas. The highest one has an estimated elevation
