All the coal received liy the T'nited States Government from Virginia 

 and West Virginia had percentages of ash 0.03 and 0.09 lower respectively 

 than the average ash from "nineteen of the leading mines of the State 

 (Indiana).""' Pennsylvania coal showed 1.70% more ash than the Indiana 

 coal. No one thinks that Indiana coal is as good as comparisons fi'oni 

 these analyses indicate. However, if Indiana coal is given the value of 

 11.04% ash and 12.719 B. T. U., it will occupy a position where it seems 

 to belong. While there are objections to Indiana coal, nevertheless it makes 

 a good showing when compared with the eastern coals, which are actually 

 of a higher grade. A maximum number of heat units for a dollar is what 

 one wishes in a coal and "* * * it is possible to burn coal of low 

 heating value as efficiently as higli grade coals."'- Indiana coal, as deliv- 

 ered, generally contains more moisture than eastern coal, say 10 per cent, 

 in the place of 3 per cent. There is. say 1 per cent., additional expense 

 for the extra cost of handling the greater amount of ash in the Indiana 

 coal. This gives eastern coal an advantage of, say 8 per cent., over 

 Indiana coals, i. e., if two samples of coal (dried at 103 degrees Centi- 

 gi'ade) have equal calorimetric value, the Indiana coal, as delivered (with 

 the water in it) is worth 8 per cent, less than the eastern coal. The 

 B. T. U. values of Indiana coal, after deducting 8 per cent, for the excess 

 of water and ash, were compared with the B. T. U. values of coals from 

 the different States which are represented in the United States Purchase 

 Bull.-' 



If one ton of Indiana coal is wortli $2.00; then 

 One ton of Pennsylvania coal is worth $2.45 ; 

 One ton of West Virginia coal is worth $2.52 ;
