It seems to the uninitiated a simple matter toshovjl coal into the furnace of a boiler, supplythe boiler with water, and use the resulting you who do this, know that lo do it right, to doit so aa to get the best attainable results, is very farfrom being a simple matter On the contrary youknow that it is an txcetdingtj complex matter amatter about which the wi-est will always findsomething to learn We are continually being told that tht process ofgetting mechanical work from cua! is an extremelywasteful process. In the sense that it is possible toutilize but a small perctj|ta>-e of the latent energyof coal, OS useful work this is true enough But.
