248 GEOLOGY OF OHIO. 



No. 1 is really a bituminous shale. It will burn, but is not equal to 

 the poorest cannel. Below No. 6 the coal is very bad and contains nouch 

 pyrites in nodules, while above the same parting there are numerous 

 streaks of the same. The coal here is by no means equal to that obtained 

 east of the Muskingum River. The same coal is worked by Mr. C. Mat- 

 tingly and by Mr. Lane, at whose banks it is said t6 be four feet thick. 

 A specimen from Mr. Bland's bank gives the following: 



Specific gravity 1.308 



Moisture 3.00 



Volatile comtiiistible matter 38.40 



Fixed carbon 56.70 



Ash 1.90 



Total 100.00 



Sulphur 1.83 



Sulphur remaining in coke 0.79 



Sulphur forming of the coke 1.34 



Fixed gas per pound, in cubic feet 3.80 



Character of coke Compact. 



Color of ash YcUott. 



A cannel coal, probably No. 4, was formerly worked on the old Blunt 

 farm, near the line between Cass and Muskingum. It was found impos- 

 sible to determine accurately whether it is No. 4 or No. 3a, as there is no 

 satisfactory exposure of the accompanying strata. The thickness' is vari- 

 able, ranging from four to seven feet. It was mined to a considerable 

 extent by a Newark company for distillation. The discovery of petro- 

 leum rendered the manufacture unprofitable, and the works have fallen 

 into decay. 



The limestones here are three in number, each with a coal bed under 

 it. The ore bed can be traced into this township, but has never been 

 worked, and there are no means of determining its thickness or value, as 

 the exposures are very bad. 



Madison Township. — At Mr. J. Closen's salt works, in the northern por- 

 tion of the township, Coal No. 6 is worked. It is about four feet thick, 

 and yields a good coal throughout, though the upper portion is the better. 

 Near the works Coal No. 4 is seen by its smut, accompanied by the gray 

 limestone above. The salt well is 408 feet deep, beginning about 120 

 feet below Coal No. 6. No record of the boring could be found. The 

 brine contains from five to six per cent, of salt, and the average weekly 

 manufacture is about fifty barrels. A specimen of Coal No. 6, obtained 

 here, gives as follows
