HOCKING VALLEY. 



683 



No. 3 gives the average of eighteen samples from this seam, in the 

 immediate valley of the Hocking and about Straitsville. 

 No. 4, an analysis of the Ashland, Kentucky, furnace coal. 

 No. 5, an analysis of the Brazil, Indiana, furnace coal. 



As the analyses, condensed in column No. 1, are from chips brought 

 up in the sand pump from drilled wells, it is quite probable the amount 

 of ash is increased by the presence of shale from the roof of the coal. 

 In all other respects the coal is fully up to the standard of this coal, and 

 it will be observed that there is an important improvement in the di- 

 minished amount of combined water. The sulphur is also quite low, 

 and the greater part of it passes off in the volatile! matter, leaving a coke 

 almost free from this impurity. The analysis o: the borings from the 

 well on Green Run, showed 0.60 per cent, of fulphur, while there re- 

 mains in the coke only 0.054 per cent. 



The following is the result of the analysis of a specimen from the 

 lower bench of the Shaft coal, made by Spencer B. Newberry : 



Moisture 6.11 



Volatile combustible matter 35.22 



Fixed carbon 51.19 



Ash 7.48 



100.00 



Sulphur 1'02 



In the coke used in the Cleveland iron district, England, Mr. Bell re- 

 ports the average amount of sulphur to be about 0.60 per cent., or nearly 

 twelve times as much as that remaining in the Green Run coke. 



All the wells sunk in this field, disclose the coal at its proper horizon, 

 and there are no indications of erosion. At Chauncy, it has been mined 

 by a shaft 100 feet deep, for more than thirty years, is from six to seven
