586 GEOLOGY OF OHIO. 



mines to the soutli and east of Coshocton, are altogether in Coal No. 6. 

 Those of the Home Mining Company, a mile south-east from the town, 

 isupply a large part of the coal there consumed. They are situated on 

 the west side of the high hill, near together, and are worked by means 

 of twelve separate entrances. The bed is about 150 feet above the level 

 ■of the railroad, and the coal is run down to the town by a gravity track, 

 the cars being hauled back by mules. The thickness of the bed is three 

 feet eight inches; the coal is very free from sulphur, bright, hatd. and 

 compact, and breaks with clear and brilliant smooth faces; is better 

 adapted for steam and domestic purposes, than for blacksmiths' use. not 

 having the melting and coking quality to the extent they require ; still, 

 it is in demand for this purpose, and is, in fact, the best this part of the 

 -country affords. It is transported by railroad to Newark and Columbus, 

 and is said to be as good for railroad use as any coals obtained there It 

 is worked by large chambers, the roof being strong A thin s<am of 

 shale divides the bed into two benches, and the upper bench supplies 

 the best coal. It is overlaid by gray shales and sandstones; and 115 feet 

 above it is the outcrop of another coal bed (No. 7), not opened, overlaid 

 with limestone and some iron-ore — the position in which to look for the 

 black-band iron-ore. The gray limestone is about sixty-five feet below 

 •Coal No. 6. 



Of the Coshocton Mining Company, Colonel Stanhope is manager. 

 About 40,000 bushels are mined per month. The analysis of this coal is 

 as follows : 



Specific gravity 1.303 



Water 3.1-0 



Ash i.yo 



Volatile matter 37.10 



Fixed carbon 57. 20 



100 00 



Sulphur 1.75 



■Sulphur left in coke 0,11 



Sulphur forming percentage of coke IS 



Fixed gas, per pound, c. f M-i 



Ash — .. .. gray. 



Coke compact. 



This analysis indicates a superior coal, specially adapted for coking, 

 from its cementing character and extraordinary loss of sulphur in coking. 

 The seam contains, here, as generally, a slate parting, which can only be 

 xemoved by some care in mining. 



In the hill north-east from the last described locality, toward the coal
