General Features. — By reference to the details of these records it will be 

 observed that the Upper Coal Measures ' XV i, Barren Measures ( XIV |, 

 Lower Coal Measures (XIII), Pottsville conglomerate (XII), and the 

 Mauch Chunk shale and Mountain limestone (XI) are all well repre- 

 sented, and that the latter series rests immediately on top of the Mount 

 Morris oil sand, which corresponds to formation X of Rogers, or the 

 Pocono sandstone of Lesley. 



Another interesting fact will also ho observed, viz, that the interval 

 from the Waynesburg coal to the tup of the oil sand is 1,624 feet at Mount 

 Morris, 1,706 feet at Fairview, and 1,725 feet at Mannington. thus show- 

 ing a progressive increase in this interval from Mount Morris to Manning- 

 ton of about 100 feet. This condition of affairs, as will he seen hereafter. 

 plays a very important part in determining the exact course of the Mount 

 Morris oil held when traced south westward.
