COAL. 
97 
In a report on "run of mine" made to James W. Ellsworth & Co., 
by Doctor Bogdahn, chief chemist of the United Coke and Gas Com- 
pany, Otto, Allegheny County, Pa., analyses of dry coal and of 
crucible-made coke from the Ellsworth mines are given. The com- 
positions were as follows: 
Analyses of dry coal from Ellsworth collieries and of coke made in a, crucible from the same coal.

A comparison of this coal analysis with those on page 9(5 made by 
the United States ( Geological Survey shows lower ash and sulphur than 
the other samples, indicating that this is probably picked coal and 
that the analysis may be taken as representative of tne best coal in 
the quadrangle. 
In addition to these analyses, several others have been gathered 
from miscellaneous sources and are given in the following table. In 
several cases where analyses were made years ago it is not known 
whether or not the locality is inside the quadrangle, but the name of 
the township indicates the probability that it is within the area or close 
to its borders.
