The uplands in eastern Chautauqua County, N. Y., as ah'eadj" noted, 

 rise in a few places to an altitude of 2,100 feet, but are generally 1,600 

 to 1,800 feet. Probably the ice slieet extended to the highest points at the 

 time it was forming the Cleveland morainic belt, for the uplands are 10 to 

 15 miles farther north than the southern end of Lake Chautauqua and the 

 supposed limits of the ice tongues in Cassadaga and Conewango valleys; 

 but, as above noted, there seems to be no definite moraine on these uplands. 

 The altitude in Cassadaga and the Conewango valleys, as indicated above, 

 is scarcely 1,300 feet. East of Conewango it rises within a few miles to 

 nearl}^ 2,000 feet. From there eastward to the reentrant angle on the divide
