with perhaps 100 feet of shales and limestone to the limestone. It may 

 be that here there is a local thickening of the Allegheny, but the section 

 is again that which is familiar in the northern counties, with the 157 feet 

 of Connoquenessing as practically the lowest member. At Clarksburg, 

 in Harrison county, about 10 miles southeast from Browns Mills and 

 11 miles east of south from Joetown, a record shows

to red beds. Here one finds the sandstone beginning directly under the 

 coal bed, and almost continuous for 396 feet, there being in the interval 

 only 40 feet of clay and coal beds. This condition recalls that at Web- 

 ster, and it is found measurably at Long Run, in Doddridge county, 

 15 miles southwest from Browns Mills and 22 miles west from Clarks- 

 burg, for the sandstone is almost continuous from the Freeport to the 

 upper portion of the Pottsville, which there is a sandstone 143 feet thick. 

 The lower part must be shaly, for the driller reports only " slate, shells, 

 and limestone " 230 feet to the limestone. In northern Doddridge, 10 

 miles west of north from Long Run and about 20 miles south of west 

 from Joetown, the record, beginning at 864 feet below the Pittsburg, 

 shows seven alternations of shale and sandstone, in all 240 feet, with 

 underlying beds
