68 GEOLOGY OF OHIO. 



In the valley of the Conotton, Coal No. 6 crops out at a great number 

 of localities, and may be traced nearly to Leesburgh. At New Cumber- 

 land it is five feet in thickness, the upper bench remarkably bright and 

 handsome. 



Near New Philadelphia this is the coal mined by Daniel Knisely, J. W. 

 King, and S. G. Crite. At Knisely's mine, below town, the coal is fifty- 

 seven inches in thickness, with a slate parting eight inches above the 

 bottom ; coal of medium quality. At King's bank it is three and a half 

 to four feet in thickness, with a band of pyrites one foot from the bottom; 

 coal of fair quality. At Crite's mine the coal lies sixty feet higher than 

 at Knisely's, and the outcrop of Coal No. 4, with its limestone, is seen 

 ninety feet below it. 



South of New Philadelphia No. 6 is opened at numerous 'places in the 

 valley of the Tuscarawas and that of the Stillwater, showing local varia- 

 tion in thickness and quality, but usually recognizable by its position, 

 its thickness, its slate or sulphur parting, and by its black and pitchy 

 appearance. 



At Dennison, Coal No. 6 is worked for the supply of the railroad loco- 

 motives and machine shops, and for shipment west. The principal mine 

 is twenty-six feet above the railroad track. The bed is three feet ten 

 inches thick, free from slate, but with a small seam of pyrites eighteen 

 inches above the bottom. The dip of the bed is toward the north-east. 

 In this direction, about three-fourths of a mile distant, is an opening in 

 the same bed, worked by Mr. J. L. Morris and his associates. The coal 

 is of similar character to that of Dennison. At the east end of Morris's 

 mine the coal is considerably below the railroad. In this vicinity it is 

 carried by its easterly dip beneath the surface, and, going eastward, 

 nothing more is seen of it before reaching Steubenville, where the valley 

 of the Ohio is cut nearly to its level, and it is reached by shafts. 



Between Dennison and New Philadelphia Coal No. 6 is opened at in- 

 tervals in the hills along the east side of the Stillwater. The mines are, 

 however, for the most part worked only in the winter. The coal here 

 seems to be of the same general character as at Dennison. 



In the district lying between the New Philadelphia road and Rockford, 

 this coal seam crops out along the hill road from Eastport, and still more 

 conspicuously in the valley of Pike Run. In this valley the coal is from 

 four and a half to five feet thick, but sometimes contains two small seams 

 of pyrites. Messrs. 0. Young & Co. mine it quite largely for shipment. 

 Their coal is of good quality, with a parting two feet from the bottom, 

 the lower bench containing more sulphur than the upper. At Hanna- 

 iown it is just above the surface of the valley, and beyond this locality
