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 benth remarkably bright and 
handsome. | 
Near New Philadelphia this is the coal mined by Daniel Knisely, J. W. 
King, and 8. 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. O. 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- 
town it is just above the surface of the valley, and beyond this locality
