100 THE ALLEGHANY COAL FIELD. 



fore they are not easily traced from place to place, especi- 

 ally in the new and mountainous districts, where mines are 

 not much worked. 



1 first present the measured and estimated dip of the 

 rocks, beginning at the Pennsylvania line on the North, 

 and proceeding East and South into Virginia. These are 

 taken from the Pennsylvania and Virginia Reports. 



Valley of the Alleghany River, (Tarentum,) S. S. West, 

 15 feet per mile. 

 Valley of the Monongahela, (Morgan town,) nearly West. 



Valley of the Kanhawa, seven miles below the Falls, 

 Northwest, 2° per mile. 



This large dip on the Kanhawa does not hold good 

 throughout the valley, being subject to deductions for 

 local counter dip. Below Charlestown, Virginia, it is 

 reversed, and rises towards the Northwest to the Western 

 margin of the field, at the mouth of the little Scioto, in 

 Ohio. 



From thence I have obtained frequent measurements, 

 by levels made along lines from one to ten miles in length, 

 and in some cases forty miles, which give precise results. 

 They are shown in the following table:
