116 J. J. STEVENSON CARBONIFEROUS OF APPALACHIAN BASIN 



The Upper Freeport coal bed is from a few inches to 5 feet or more in 

 thickness, the variations being so great that the bed is only locally im- 

 portant. The Lower Freeport is unimportant. A thin coal was seen at 

 a little way northeast from the village of Cambridge, which Professor 

 Orton is inclined to refer to the Upper Kittanning. The Middle Kit- 

 tanning shows its characteristic roof, in which the nodnles often contain 

 a nucleus of sphalerite. The coal is good enough for local use and the 

 bed is 3 to 4 feet thick. The Lower Kittanning is accompanied by its 

 fireclay. The Brookville varies from 18 inches to 5 feet and yields poor 

 coal. The interval to the Middle Kittanning in one township is only 

 26 feet, the Putnam Hill limestone being present.* 



In Belmont county, east from Guernsey to the Ohio river, the Alle- 

 gheny is deeply buried. Xo information is available for this county 

 aside from the record of a well in Washington township 3 or 4 miles 

 from the river, which shows only shales for 750 feet below the Pittsburg 

 coal bed to a great sandstone which belongs to the Pottsville.f 



Returning to the west: In Wayne county, west from Stark, Mr Read 

 identifies with Goal 6, the Middle Kittanning, a bed only 25 to 30 feet 

 above the Gray or Putnam Hill limestone. It is 2 to 4 feet thick, with 

 black lustrous caking but sulphurous coal. It has the characteristic 

 roof, black fossiliferous shale. The Brookville coal bed underlies the 

 limestone and is 2 to 4 feet thick, sometimes cannel and generally slaty 

 and sulphurous. The Freeport sandstone was seen at one locality 25 feet 

 thick and, as in parts of Stark, Tuscarawas, Carroll, and Harrison, very 

 coarse or finely conglomerate. J 



Holmes county is south from Wayne and west from Tuscarawas. 

 Professor Wright's generalized section for the county is :
