SUMMARY. 

 From these results, ihe Kansas coals thus far examined are to be arranged in the 

 following order as regards their evaporative powers. 



[Note. — About one-half the evaporative powers here given under the 10 per cent, correction, will 

 be obtained in practice.]

The coals depreciate in their steam-producing powers from the southeastern 

 part of the State toward the north and west. Prof. Bailey finds they depreciate in 

 the amounts of fixed carbon in a similar order.

THE COMPOSITION OF KANSAS COALS. 



BY E. H. S. BAILEY, PH.D. 



The eastern part of the State of Kansas is fortunately underlaid with a fair qual- 

 ity of coal. With the increased population, the introduction of important man- 

 ufacturing industries, and the extension of the several lines of railway, there is
