In many sections of the West, how- 

 ever, water power possibilities are not 

 present, and it becomes necessary to 

 locate a cheap fuel supply for the pro- 

 duction of steam power. Coal and oil 

 are found in many parts of the arid re- 

 gion, and aften may be delivered at 



rieties of coals from all parts of the 

 United States. The results of various 

 commercial tests indicate that under 

 similar conditions one pound of the 

 bituminous coal of Pennsylvania or 

 West Virginia will evaporate about 10 

 pounds of water into steam ; one pound 

 of Illinois or Missouri coal will evapo- 

 rate about / pounds of water into 

 steam ; and one pound of western lig- 

 nite, about five pounds.

the pumping plants at very low cost. 

 Western coals are, as a rule, poorer 

 steam producers than coals from the 

 Eastern or Middle States. Tests to 

 determine the relative evaporative 

 powers are now being made by the 

 United States Geological Survey at tS. 

 Louis, and the data obtained will be 

 reliable and important for comparing 

 the steam producing qualities of va- 



Many grades of coal besides lig- 

 nite are, however, found in different 

 sections of the West, Colorado alone 

 producing coals ranging all the way 

 from lignite to anthracite. On account 

 of the extreme variations in the kinds 

 of western coals it is just as important 

 to know the steam producing power 

 of the coal to be used as its cost per 

 ton, in order to estimate closely the
