In Brown township no opening upon No. 7 was seen, but the outcrop 

 of the coal was observed at several localities near Waynesburg, and at 

 each of these there were evidences of ore in connection with it. Through- 

 out this vicinity it lies one hundred feet above Coal No. 6, which is mined 

 by Mr. R. B. Hamilton, near Waynesburg. 



The interval between Coals Nos. 6 and 7 varies greatly. Near Carroll- 

 ton it is from forty to sixty feet ; near Leesville, thirty-five ; in northern 

 Monroe township, sixty ; while in Rose and western Brown it is one hun- 

 dred feet. The Mahoning sandstone, resting upon Coal No. 6, varies from 

 six to thirty feet in thickness. 



Coal No. 6 is the important bed of the county, but, unfortunately, is 

 available only along the valleys of the Conotton and Sandy Creek, which 

 include portions of Brown, Union, Monroe, and Orange townships. In 

 Union township, about one mile south from CarroUton, on the Indian 

 Fork of Conotton, it is mined extensively to supply CarroUton. At Mr. 

 John Moody's bank the following section was obtained :

This coal shows a considerable proportion of pyrites, both in seams and 

 nodules. When exposed to the atmosphere, it soon becomes covered with 

 white streaks, but shows little tendency to disintegrate. No. 3 of the 

 section is the best for burning, and is very clean. No. 6 has numerous 

 streaks, but few nodules of pyrites. No. 7 is variable in thickness, but
