occasionally either splint or impure cannel. Overlying the coal in this 

 county is a succession of massive more or less pebbly sandstone, shown 

 on one knob in three benches, but with the intervals concealed. The 

 thickness is 200 feet. This great sandstone mass, the Charleston sand- 

 stone of M. E. Campbell, is a conspicuous feature from Kandolph county 

 southward. Passing over into Nicholas county, one finds the blossom 

 of the Brookville near Gilboa under 150 feet of massive pebbly sand- 

 stone, all other coal beds appearing to be absent. Two miles west from 

 this locality the Kanawha black flint appears, just over the Brookville 

 coal bed and under the great mass of sandstone. In western Nicholas, 

 the Flint is 8 feet thick and 10 feet above the Brookville, which is triple, 

 two of the benches being splint. From this locality, Doctor White has 

 followed the Brookville eastward and southward; it breaks into many 

 benches and the shale partings show great variations in thickness. At 

 Powell mountain in this county the section is:

At this Nicholas locality one is on the waters of Gauley river, along 

 which the Brookville coal bed is seen in all the hills to the Kanawha 

 river, in Fayette county, where one has this section at the mouth of Arm- 

 strong creek:

Number 9 is the Stockton coal bed of the Kanawha region. The exact 

 relations of the "Number 5" coal bed can not be determined. The in- 

 terval between it and the Stockton shows great variation along the Ka- 

 nawha, but the bed is characteristic throughout, its coal differing from 

 that of any other bed in the section. It is apparently the intermediate 

 bed occasionally seen farther north and doubtless represents a Kittanning
