NEW JERSEY AND PENNSYLVANIA ORISKANY 311 



be seen above W. Nearpass' quarries ; near Peters valley ; at Walpeck Center, and 

 west of Flatbrookville. Lying on this is a thick body of shale, which constitutes 

 the principal part of the formation. 



" The shale is light-colored, soft, and disintegrates easily. Some of the beds are 

 very calcareous, while others are gritty. Fossils are quite abundant, especially in 

 the upper layers, near the Cauda-galli grit. 



"This formation maybe seen almost everywhere, from the Stateline to Walpeck 

 bend. ... A fine locality for examining rocks and included fossils is along 

 Chamber's Mill brook, northwest of Isaac Bonnell's residence. 



"As estimated, west of Flatbrookville the shaly rock is about 120 feet thick. 

 From the breadth of the outcrop west of Walpeck Center, and with a uniform dip 

 of 40 degrees to the northwest, its thickness would be made to be over 300 feet. 

 The difficulty of always fixing the angle of the dip renders this examination a 

 matter of uncertainty." 



The Oriskany of New Jersey is intimately connected with that of New 

 York and Pennsylvania, and the reader is referred to these sections of 

 this paper for other details.
