parting than in other portions of the bed, and that is known as the 

 "bearing-in bench." For the most part the coal is of good quality, and 

 contains about thirty-three per cent, of volatile matter. 



In Moorefield township it is extensively worked, near Moorefield village, 

 by Mr. C. A. Skinner in section 23, Mr. J. Comper in section 22, Mr. R. 

 Moore in section 25, Mr. J. Mansfield in section 17, and by many others. 

 A section of Mr. Wallace's bank in section 12 is as follows :

In Mr. Mansfield's opening the coal is about five feet thick. The pyrites 

 band is well marked, and nodules of pyrites are sometimes found weigh- 

 ing twenty or thirty pounds. There is no roof-coal visible in any of the 

 openings, the bed being roofed by two feet of shale. The coal is gener- 

 ally regarded as inferior to that obtained further to the east. 



In Athens township this coal is worked at numerous openings for 

 domestic use. It is accessible in nearly all the deep ravines, and may be 

 easily found, as it lies from ninety-five to one hundred feet below Coal No. 

 10, which is frequently seen along the ridge roads. The roof-coal was 

 not seen at any of the openings examined, and the roof appears to be 

 sandstone. Situated for the most part in ravines, the openings afford no 

 satisfactory section of the overlying rocks. At Mr. James Clemens's 

 bank, section 30, the coal is as follows :

Here the pyrites streak in the upper bench is not well marked, though 

 the upper parting contains much of the sulphuret. The parting near 

 the bottom is full of pyrites, and is distinguished near the mouth of the 

 bank by its white incrustation. 



In Short Creek township the openings are numerous near Harrisville
