about five miles southwest of Lake Mohonk, and occupies a shallow 

 basin of purely glacial origin. The observations were made in Sep- 

 tember, 1878, are uncorrected for magnetic variation, and are recorded 

 in order along the usual path taken by visitors from the hotel to the 

 summit of Sky-Top and back.

At this northern end of the range, where its own trend is about S. 

 by E., the course of striation and the main glacial movement appear 

 to have been about S. by W. The divergences from this direction in 

 the instances noted, from S. even to S. E., appear in some cases to be 

 merely local variations through valleys and around the shoulders of 

 the range. Those on and near the summit of Sky-Top may possibly 

 record the southeastern movement of the older and thicker glacial 

 strearh, to which reference has been more fully made in my observa- 

 tions on the glaciation of the Catskills.*
