A little higher more argillaceous and nearly olive shales occur in which 

 there are more species, Chonetes being abundant. This zone is but a 

 few feet in thickness when the shales again change to those that are 

 nearly bluish-gray, containing about the same species. On the bank of 

 the creek beloAv the road are bluish-gray to gray shales which are decidedly 

 argillaceous in composition, and when weathered more nearly buff in 

 color though along the stream they are for the most part quite compact 

 and bluish. Some of the layers show large, irregular, concretionary 

 structure. These shales which are quite bluish and contain numerous 

 small concretions, some of which are calcareous, are about in line with 

 the weathered buff and red shales of the middle outcrop on the road above. 

 A few specimens of Spirifcr mucronatus (Conrad) were found in the 

 shales on the bank of the creek but they are rare. 



A ledge of fairly massive, greenish-gray sandstone, as weathered, 

 occurs by the side of the road which is near the top of the Eomney 

 formation. It is supposed to be at about the same horizon as the sand- 

 stones in Allegany County which occur near the top of the Eomney. The 

 sandstone is quite compact, breaks into block-like pieces and has a dip 

 of 60° N., 50° W. The rocks are pretty well covered along this part of 

 the road which is to be regretted because the line of transition from the 

 Eomney to the Jennings formation is thereby obscured. No fossils were 

 found but there is vei^y little opportunity to hunt for them as the rocks 

 are so higUy inclined and the outcrops are so slight. After crossing a 

 narrow covered area there are fissile, olive shales with an occasional thin 

 sandstone, 2 or 3 inches in thickness. These shales stand at a high angle 

 and only the loose pieces could be examined but in these were found 

 fragments of Pterochaenia fragilis (Hall) and Goniatites. These rocks 

 do not have the lithologic appearance of the Genesee shales of Allegany 

 County, which appear to be wanting, and they were referred to the
