188 GEOLOGY OF OHIO. 



is the purest portion, and in good repute for smithing purposes. No. 9 

 contains a band of bone coal, three to four inches thick, which ignites 

 with difficulty, and after burning leaves a flaky ash, like that from hick- 

 ory wood. Nodules of pyrites are of frequent occurrence in this layer. 

 No. 11 makes the hottest fire, but leaves much cinder. 



Directly opposite this opening is one belonging to Mr. Gause, in which 

 the section is the same as that already given. The bed here is very badly 

 cut out by horsebacks and clay veins. The latter strike the bed at an 

 angle of about 50°. The forraer are so serious as to impair the value ©f 

 the bank. One hundred yards from the mouth a sandstone horseback 

 crosses the entry, which replaces not only the coal but also the underly- 

 ing rocks to a depth of fifteen feet. Its width, as shown in the entry, is 

 twenty yards. A few yards beyond this another occurs, and to avoid it 

 the entry was turned, so that nothing is known respecting its extent. 

 Unfortunately for science, though fortunately for themselves, the owners 

 of the adjoining banks have not driven their entries in the direction to 

 meet these horsebacks, and it is impossible to determine, with any de- 

 gree of accuracy, the extent or direction of the disturbances. The re- 

 moval must have occurred during or immediately before the deposition of 

 the sandstone above, as the horsebacks are of a constitution similar to 

 that of the sandstone stratum. In the neighboring bank, belonging to 

 Mr. Staley, the coal is from five to six feet thick. Near CarroUton the in- 

 terval between this bed and the Crinoidal limestone is only one hundred 

 and forty feet. In Tuscarawas and Guernsey counties it is two hundred 

 and forty to two hundred and sixty feet. 



Midway between CarroUton and Cannonsburg, on the border of Monroe 

 township. Coal No. 6 is mined by Mr. W. Scott, at whose opening the fol- 

 lowing section is seen-:

In the entry the coal occasionally becomes five feet six inches, and in 

 one spot it reaches six feet. Throughout the greater portion of the bed 

 little pyrites is visible, and nodules occur only near the bottom, where 

 they are comparatively rare. "Where exposed to atmospheric influence.
