George Westinghouse was another Pittsburgh capitalist. His early days were spent in making agricultural implements in Schenectady. He was called Lazy George because he was always making pieces of machinery to save doing work with his hands. Later, by his invention of air brakes for trains, he became rich. Choosing Pittsburgh as his home, he established in and near the city the great Westinghouse Electric Company. It was Mr. Westinghouse who gave to Pittsburgh natural gas, conveying it through forty miles of pipe from Murrysville. Towering above Pittsburgh are high hills, which are reached from the business districts by inclined planes. Passengers and freight are carried up the inclines in cable cars. Up the steepest of these planes, the Monongahela, whose summit is four hundred feet above the river, the railroad runs through a tunnel and brings the passengers out upon a high bluff. [Illustration: FROM THE HEIGHTS ABOVE THE CITY] From the heights above the city one views the surrounding country--a wonderful panorama of hills and valleys, with the three great rivers, spanned by seventeen splendid bridges, stretching away in the distance. In every direction are towns called "little Pittsburghs," where live the workers engaged in the gigantic industries of the Pittsburgh district. And looking down, one sees the Point--the center of this great city, the heart of the "workshop of the world." =PITTSBURGH= FACTS TO REMEMBER Population (1910), over half a million (533,905).
