COAL OPENINGS. 



Pittsburgh Coal. — The Pittsburgh coal bed has been opened at only 

 one place on the Peytoua tract or in the neighborhood ; and that was near 

 the top of the mountain above the mines and east of them. The section 

 measured there was as follows, from above downward : 



FT. IN. FT. IN. 



Loose sandstone blocks, somewhat limy ? 



Sand rock, thick

 it is in the northern part of the State, that it seems not unreasonable to 

 hope that its average throughout the tract may prove better than at this 

 opening. 



On Lens creek the bed forms but small patches on the hilltops, and 

 has (1872) been opened in only one place, namely, on the hill opposite 

 Mrs. Nuby's house and King's Hollow, about the middle of the eastern 

 edge of the map ; with the following section, from above downward :

Coal, with half-inch layers of clay at about four and

 The opening is not a very perfect one, and perhaps does not show the
