AN ADVERTISEMENT OF THE WESTINGHOUSE ELECTRIC & MFG. CO. * PITTSBURGH, PA. Electricity's eyes never close.., its service is never asleep ABABY'S cry in the night .. a midnight prowler ... sickness that strikes in the dark. How grateful we may well be in emergencies for the never-failing service of electric light! Yet how few of us realize what it takes to make that service possible - what it has cost over the past 50 years in the way of invest ment, invention, engineering, and human toil. Trace the wires from your light switches, and you will find them connected to an intricate system of transformers, pro tective devices, transmission lines, substations and generat ing plants that cost millions to build. To keep such systems functioning day and night, through heat and cold, storm and flood, costs millions more. Vast additional sums go yearly into research, development, and improvement. Electric service can never be called "perfect," because its engineers are always making it better and cheaper! Westinghouse contributions to this progress have helped to blaze the trail ofelectricity from its source to its infinite uses. The generating systems - the transformers and networks the lamps that burn longer and brighter at less cost - all owe something to Westinghouse co operation with progressive power companies. This partner ship in the public interest is of direct benefit to every industry, business office, farm and home, all over America. @ Westinghouse "Mention the Geographic-It identifies you."
