HOCKING VALLEY COAL FIELD. 949 
The figure clearly represents the structure and general character of 
the seam. The roof coal, 29 to 33 inches in thickness, is not taken 
down in entries, nor in rooms, until pillars are drawn, as it makes an 
excellent roof under which to work. A portion of it is finally recovered. 
Its composition, as sampled in the mine, is shown below:

This analysis indicates that the top coal brings down to some ex- 
tent the standing of the lower benches. The latter run higher in fixed 
carbon by 3 to 5 per cent., and lower in ash by abcut 2 per cent., but 
there is no warrant for leaving in any mine of the State any coal of 
this character that good mining can bring out. 
The upper bench of the normal seam and the lower of the supple- 
mentary seam are run together in the 50 inches of coal that are shown 
above the second slate. The division comes about 5 feet from the bot- 
tom of the coal. The 4 inches of soft coal come in the placejof the 
horn coal of other mines of the vicinity. 
In the Fannie Furnace mine, which belongs strictly; to the same 
body of coal, the entries being worked through from one mine to the 
other, the roof coal is not always found. A section of the coal taken 
here is shown in the following diagram:
