This coal contains a notable portion of pyrites, and is not usually held 

 in favor. It was found impossible to procure satisfactory specimens for 

 analysis. 



The strata above Coal No. 10 are somewhat variable. Usually there are 

 two beds of limestone of considerable thickness, but occasionally only one 

 is found. These limestones are very ferruginous, and apt to weather into 

 an ochreous mud. The upper one is sometimes conglomerate. 



Coal No. 11 is a thin seam, of no economical importance, is nowhere 

 worked, and is seen only on the ridge roads leading from Cadiz and Moore- 

 field to New Athens. 



Coal No. 12 is seen only at the junction of the Flushing and Moorefield 

 roads, in Athens township, two miles west of New Athens. 



SUMMARY. 



The important mineral of Harrison county is coal. The distribu- 

 tion is very irregular, owing to the extensive removal of Coal No. 8 

 by natural agencies. Coal No. 7 attains to suflicient thickness in Mon- 

 roe and Washington townships to be of economical importance. For 

 domestic use it is fully equal to Coal No. 6, and being of the same thick- 

 ness along the Pittsburgh, Cincinnati and St. Louis Railway, could easily 

 be brought into competition with it. Coal No. 8, however, is likely to 

 be the main source of supply for home use and export, as it is more gen- 

 erally distributed, and is thicker and better than any other seam. The 

 analyses of this coal show a large proportion of volatile combustiljle mat- 

 ter, rendering it a useful gas coal, although the sulphur may make the 

 purification process somewhat expensive. The percentage of sulphur 

 remaining in the coke manufactured from it in the ordinary way unfits 

 it for use in the reduction of iron, and necessitates washing previous to 

 coking. The washing process has been introduced successfully in Jefier- 

 son county, and will be here as soon as a demand arises for the coke.
