inadequacy of water power as a substitute for oil and coal. Those who 

 think otherwise usually consider the question from the standpoint of 

 factory power only, leaving out of consideration the enormous quantities of 

 energy required to heat our homes, and to supply heat for such processes 

 as ore smelting, cement manufacture, brick, tile and glass making, and 

 thousands of others. To equal one ton of coal per month for heating 

 purposes one would require the entire output of a fourteen horse-power 

 plant, running twenty-four hours per day thirty days per mouth. If there 

 are five hundred thousand families in Indiana and if each family con- 

 sumes an average of two tons of coal per month during the winter season. 

 the consumption is the heat equivalent of fourteen million horsepower. 

 Remember, too. that Indiana is not a very populous State and that its 

 climate is not severe. 



Professor Soddy states the facts in his little volume on "Matter and 

 Energy" when he says that "the age in which we live, the age of coal, 

 draws its vivifying stream from a dwindling puddle left between the com- 

 ings and goings of the cosmical tide." 



We are to "witness a race, a race between science on the one hand an 1 

 the depletion of our natural resources on the other hand." This race will 

 be run chiefly by pure science, not by applied science. Engineers and in- 

 ventors make their reputations and their fortunes by devising new and im- 

 proved methods of using our natural resources ; they are not concerned with 

 the atom, the latest and the greatest energy reservoir discovered by man. 

 We must look to such scientists as Beequerel, Curie. Rutherford. Ramsay. 

 We must look to the humble, overworked, underpaid scholar toiling away in 

 his laboratory. If he fails us. darkness comes.
