Pease Township. — In this township Coal No. 8 is extensively worked 

 along the Ohio River, on Wheeling Creek, and near Kirkwor^d. Coals 

 Nos. 8c, 9, 10, and 11 thin out either altogether or so as to be traceable 

 with the utmost difficulty, while Nos. 11 and 12 attain extraordinary 

 thickness in the central portion of the township along the river. 



In the deep cut, on the road leading from Martinsville, is a coal nearh' 

 six feet thick, containing much pyrites, and evidently a very inferior 

 article. It is slaty in structure, and resembles the low-grade cannel 

 so common in the Coal Measures in Ohio. At this locality it is three 

 hundred and twenty feet above Coal No. 8. On the property of Mr. W. 

 J. Rainey, in section 13, it is four feet thick, and lies about three hundred 

 feet above Coal No. 8. On Captain R. Crawford's property, near Bridge- 

 port, it is seen three hundred and forty feet above No. 8. It is evidently 

 of no economical value, and is Coal No. 12. 



On Captain Crawford's place, at two hundred and forty-five feet above 

 Coal No. 8, a bed three feet six inches thick is worked. The immediate 

 section is:

The development of this coal, No. 11, is local. The ore overlying the 

 coal is worthless, owing to the large proportion of sulphur. The coal
