northwestward, to within ten miles of Wheeling, when 

 the strata again rise and soon bring the Pittsburg coal to 

 the surface. 



On the eastern flank of the "Dividing Ridge," Dunkard 

 creek rises, and flows a little north of east, reaching the Mo- 

 nongahela two miles above Greensboro, Peun. The eastern 

 section was made along this stream. 



On the opposite side of the ridge and a few miles north, 

 Wheeling creek rises, and, following a southwesterly direc- 

 tion, enters the Ohio at Wheeling. The western section, 

 commencing on the south fork, was taken on this stream. 



For the sake of a ready comparison we give both sections 

 together, but will confine our remarks chiefly to the eastern 

 one. 



No. I is the eastern or Dunkard creek section. 



No. II is the western or Wheeling creek section.
