exposures, and from these we learn that its highlands are 

 capped with CatsMll strata while Chemung outcrops line its 

 valleys and hill sides. 



About one and a half miles northwest from the borough of 

 Friendship, we come to one of these high rounded knobs 

 capped with the greenish gray sandstones of the CatsMll 

 which exhibit bold cliff out-crops at 1700' A. T. and also con- 

 tinue making cliffs at short intervals up to the summit at 

 1825'. The surface of the ground on the southern slope of 

 the hill is strewn with large blocks of Catskill sandstone 

 from top to bottom. 



The base of the CatsMll sandstone series is seen at 1700' 

 A. T. in the western portion of the township, near J. Kiley' s, 

 and there many detached masses of rock occur as well as 

 the out-cropping cliffs of the same. The base of the Cats- 

 7c ill measures would then occur here at 1500' above tide ; and 

 as the elevation of the Apolacon valley where it passes 

 out of the township to the north is about 1050', the CI te- 

 rming rocks would line the hill slopes for about 400' above : 

 though none of the strata can be seen, for the deep coating 

 of Drift and debris. 



CatsMll cliff sandstones are also seen capping the sum- 

 mits of hills near the eastern line of the township. 



The Chemung or Fall Creek conglomerate {3rd Oil 

 Sand?) of Sherwood's Bradford Co. section is seen about 

 li miles from the northwest corner of Susquehanna Co. just 

 over the N. Y. line. The blocks of conglomerate covering the 

 ground at this horizon (1650' A. T.) are filled with flat 

 quartz pebbles, and the matrix is a coarse dark sand. 



The crest of the Blossburg axis occurs not far from the 

 outcrop of the conglomerate and it is the passage of this 

 axis near the N. W. corner of the county which brings up 

 the C7iemung rocks to so much greater an elevation than 

 we find them along the Susquehanna river further east in 

 the vicinity of Great Bend.
