HOCKING VALLEY COAL FIELD. 985 
cover, and is weaker than usual on this account. The working of the 
lower coal is carried on in the same tract with the workings of the 
upper seam, the latter workings being kept in advance as far as prac- 
ticable. No perceptible effect has yet been produced upon the upper 
seam by the removal of the lower coal. 
The coal, as has long been known, is moderately cementing, gather- 
ing up its slack into a fairly firm coke. A dozen ovens have been erected 
here, the only ovens now in operation west of Columbiana county 
in the State. Only the slack is used in the ovens, and for reasons 
already given, this is found to be quite impure. The sulphurous 
character of the seam shows also in the slack, and the coke is so high 
in this element as to forbid its application in most foundry work. If 
the best of the seam were used for coking, somewhat better results 
would be secured. A great improvement would doubtless be effected 
by washing the slack or coal. 
The composition of the coal is shown in the appended analysis, the 
entire seam being sampled in the mine.

The analyses given of the Bayley’s Run coal in the Hocking Valley 
field show that it has lost a little fixed carbon as it has been followed 
westward. From Cambridge to the Pennsylvania line, it nowhere con- 
tains less than 50 per cent. of this element. The Happy Hollow coal 
is used almost exclusively as a steam coal. 
The Half Moon mine, No. 25 of the C. & H. C. & I. Company, is 
arranged to handle the coal of both the upper and the lower seams 
(Nos. 6 and 7) by the same chute. It is located near Akron Furnace. 
All of the descriptions already given apply without change to this 
mine. It is oneand the same body of coal as that in which the Happy 
Hollow mines are located. The working of the upper coal is not 
pressed at present. 
There is promise of a valuable field of the Upper Freeport coal in
