THE PITTSBURGH DISTRICT

Pittsburgh leads the world in the manufacture of steel and iron, glassware (including plate and window glass), armor plate, steel cars, air brakes, iron and steel pipe, tin plate, fire brick, coke, sheet steel, white lead, cork wares, electrical machinery, and pickles.

To carry on these important industries, Pittsburgh, the city of McKeesport, the boroughs of Homestead and Braddock, and many other places,—all together known as the Pittsburgh district,—have more than 5000 manufacturing plants and employ over 350,000 people. The amount paid the laborers in these factories in prosperous times is over $1,000,000 a day.

The famous Homestead mills make armor plate for battleships. At Braddock are steel works, where great furnaces turn out enough rails in a year to span the United States from the Atlantic to the Pacific. The great Carnegie Steel Company has its headquarters in the city of Pittsburgh and leads the world in the production of structural steel, steel rails, and armor plate.
