KIRKUS REVIEW

Story of electricity, its sources and its application and its future, done very simply for the uninitiated who wants to know where electricity comes from, how power is converted into usable form, how it is applied in industry, commerce, agriculture, medicine, entertainment, transportation, etc. Then there are sidelights on such subjects as lightening, balbs for night driving, and so on. The sections dealing with future developments suggest the demonstrations at the World's Fair. Plus sale for boys.
