The interval between the Wayneshurg and the Sewichdy is very much 

 smaller than in the northern portion of the State, where it varies from 

 one hundred and seventy-five to two hundred feet, averaging about one 

 hundred and eighty feet. Near Morgantown, this interval is one hun- 

 dred and eighty, at Fairmont almost the same,* at Clarksburg one hun- 

 dred and sixty, and ten miles west from Clarksburg, as given in the section 

 above. The interval seems to decrease in this direction. Were this 

 evidence absent, the character of the bed itself would leave no room for 

 doubt respecting its identity with the 'Wa,ynes'burg. 



No satisfactory exposures of this coal were observed except near the 

 railroad. Its blossom is seen on the north side of the railroad near Clarks- 

 burg, at one hundred and sixty feet above the SewicJily. It is worked 

 slightly at about nine miles west from Clarksburg, where it shows four 

 feet of coal, divided nearly midway by a clay parting one foot thick. 

 From this point westward, it was not seen until within two or three 

 miles of Smithton, where there have been numerous openings, nearly all 

 of them now deserted. At all of these, the bed is overlaid by twelve feet 

 of dark argillaceous shale, containing vegetable impressions and holding 

 midway, a layer of calcareous iron ore. At Smithton, the coal is worked 

 by Mr. Smith, at whose bank the following structure is shown : 



Shale, with vegetable impressions, 4 ft.; Coal, 2 ft. 2 in.; Claiy, 3in. ; 

 Coal, 2 in.; Cannel, 3 in.; Shale, dark-gray, fissile, 8 ft.; Coal, 1 ft. 6 in. 



The coal is not very good, owing to the considerable proportion of sul- 

 phur. The bottom layer yields the best fuel, but as it is mined by strip- 



* The Sewickly has not been seen at Fairmont, and this calculation is based on the 

 relation of the Waynesburg to the Redstone.
