While there is something to choose between the products of these 
two mines, the figures show searcely wider differences than we ought to 
expect from different rooms of the same mine. 
The range of the several elements in these 10 mines is also shown 
below:

These figures evidently show one of the very best coals of the 
State, and beyond question the steadiest in composition of any of the 
large fields. When it is remembered that each analysis represents all 
of the seam that is sent out by the miner, just as it is found in the 
mine from which it is taken, as far as this can be provided for by 
careful and thorough sampling, it will be seen that the average 
above given actually and accurately represents the lump coal that 1s 
sent out from the central and western portions of the Hocking Valley 
field. 
In strength and ability to bear handling, the coal is somewhat
