Kirhivood Township. — In the neighborhood of Hendrysburg, Coal No. 8 

 is quite extensively mined. In section 20 Mr. J. McCartney's opening 

 gives the following section : 



FT. IK. 



1. Coal 10 



2. Clay 4 



3. Hard shale- 1 



4. Coal 4 8 



No. 3 contains numerous thin streaks of coal. Mr. J. Whittle's open- 

 ing, in the same neighborhood, shows the same section. The coal is 

 handsome and quite compact. The limestone appears ten feet above the 

 coal. Formerly, Coal No. 10 was mined to some extent, and deserted 

 openings can be seen in the hills on "both sides of Hendrysburg. The 

 thickness varies little from three feet and a half, and the roof-coal is not 

 persistent. Coal No. 9 was formerly opened, but the bank has fallen in, 

 so that no measurement could be obtained. The bed is said to be three 

 feet thick. Coals Nos. 10, 11, and 12 are frequently seen in the road-side, 

 between Hendrysburg and Sewellsvillo, but are not opened. In sections 

 33 and 28 Coal No. 8 is worked, and has a thickness of five feet. In sec- 

 tion 34 this coal is worked by Mr. William Armstrong, at whose opening 

 the sandstone rests directly upon the coal, which is from five feet to five 

 feet eight inches thick. About one foot from the bottom is a band three 

 inches thick, and six inches higher is another of the same thickness — both 

 strongly marked by pyrites. Near the top two thinner streaks of pyrites 

 were observed. 



At Sewellsville Nos. 8 and 10 are conspicuous, while No. 9 is absent. 

 Coal No. 10 was opened many years ago, but the coal proved utterly
