to the limestone, which here is but 1,065 feet below the Pittsburg coal 

 bed. The shale is still present in abnormal proportion. It is not pos- 

 sible to determine how much of number 6 belongs to the Pottsville, as 

 no details are given in the record. Five miles farther west, in the same 

 county, at Moundsville, on the Ohio river, one finds, beginning at 780 

 feet

to the limestone, which is only 983 feet below the Pittsburg,- as against 

 1,170 feet in the Brown well. At Wheeling, on the Ohio river, and about 

 12 miles north from Moundsville, one finds a condition similar to that 

 already observed at several localities in southwestern Penns}dvania, for 

 a sandstone begins in one well at 564 feet below the Pittsburg, in 

 another at 534, which is continuous with the Logan sandstone. In one 

 of the wells it is broken by the Stockton (Kittanning) coal bed at 96 feet 

 below the Upper Freeport. Doctor White finds no difficulty in differ- 

 entiating the Pottsville in this well, for at 112 feet below the Kittanning 

 the section is

resting on the brown coarse sandstone of the Logan. The contrasts are 

 sharp in this well, yet in the other well, 3 miles south, where the sand- 

 stone is 706 feet thick, the portion assigned to the Pottsville is wholly 

 fine grained and white, as indeed is most of the Logan — an excellent 

 illustration of the variability of the deposits. 



At Wellsburg, in Brooke county, 15 miles north from Wheeling, the 

 Pottsville, beginning at 738 feet below the Pittsburg, shows

or 272 feet to the Logan sandstone, which is 1,035 feet. The coal bed is 

 at the Sharon horizon, number 3 being clearly the Connoquenessing. 

 At 15 or 16 miles farther north, near New Cumberland, the section is
