At Port Jervis the upper terrace is about 470 feet A. T., while 

 the lower one is 425. From Port Jervis to Huguenot this former 

 fills nearly the whole valley, but above this it narrows rapidly, so 

 that only a narrow shelf remains, leaving the lower terrace to form 

 the valley bottom. 



The two are well seen north of Huguenot village, where the 

 upper one projects out into the valley with great distinctness. 



Following up the valley, other good developments of the upper 

 terrace are at Port Clinton and again at Cuddebackville, though 

 here there is no longer the same difference in level between the two 

 terraces, the upper being only 35 feet above the lower according to 

 harometric determinations. The upper terrace also extends up the 

 valley of Neversink river as far as Oakland Yalley. At this latter 

 point there is a deposit of fine-grained pottery clay in an embay- 

 ment of the valley, which is said to be 60 feet thick as determined 

 by boring. 



At West Brookville the upper terrace appears to be wanting, 

 while the lower extends a short distance up a sniall valley'to the 

 northwest. 



From West Brookville nearly up to Wurtsboro the b'^ttom of the 

 valley is flat and swampy with an occasional island of gravel. This 

 swamp was foi'med some years ago during a period of freshet, 

 when the tributary of Basherkill washed down such a quantity of 

 gravel as to form a low dam across the valley at this point. A 

 comparatively small outlay would clean out the river bed and drain 

 the tract, which at present is, to a large extent, useless. 



There are benches at several points on the west side of the val- 

 ley between West Brookville and Wurtsboro, which are probably 

 stream terraces, but the rain wash from the hillsides, and erosion of 

 the terrace escarpment, has rendered them somewhat indefinite. 



The stream which occupied the valley when the bottom was at 

 the level of the upper terrace, has left evidence of its meanderings, 

 for on this terrace, northeast of Port Jervis, can be seen an oxbow 

 formed by the stream at this earlier date, and now occupied in part 

 by a pond. 



Summitville, on the l^ew York, Ontario and Western railroad, is 

 the dividing point of the drainage into the Delaware and Hudson 

 rivers. Homowack creek flows from Summitville northeast to
