These four samples were taken from the same opening, and represent 
different parts of the bed from below upwards. 
These analyses, copied from Prof. Andrews’s report, were made by Prof. 
Wormley, of the geological corps, as are the other analyses given in this- 
report, except where credit is given to other chemists. 
They indicate a 
peculiarity in regard to the manner in which the sulphur is combined 
in the coal, to the practical importance of which Prof. Wormley first 
called attention. 
It will be seen that a very large percentage of the sul- 
phur passes off with the volatile portion of the coal, so that if the raw 
coal is used in the smelting furnace, the coke in the stack, where the iron 
is reduced, is remarkably free from sulphur. 
For purposes of comparison we give the following table of analyses of 
selected specimens of the best qualities of the Mahoning Valley coal:
