Pittsburgh, besides being the headquarters of the United States Steel corporation, is the largest producer of steel rails and armor plate in the United States.

The Westinghouse air- brake works employ 3,000 operatives. The natural-gas interests are enormous. Since 1911 the city is governed by a mayor, con- troller, and a board of nine councilmen elect- ed at large, to replace the old bi-cameral council of 67 members.

The population of Pittsburgh is 671,639, In 1753 Governor Dinwiddie of Virginia aeat George Washing- ton to warn the French—who had advanced into the region about the source of the Ohio, which they claimed—that the Colony would resist their encroachments. The next year he despatched militia to build a fort on the pres- ent site of Pittsburgh; but a large force of French and Indians compelled them to with- draw. In the same year the French built Fort Duquesne, and Washington captured a body of French troops in the first actual fight of the French and Indian War. In 1758 Gen- eral Forbes led a powerful expedition against the fort, which was burned by the French. At Washington's suggestion the place was named Pittsburgh, in honor of the British Prime Minister. A new fort was built, called Fort Pitt, which in Pontiac's War (1763) was besieged by the Indians, holding out until relieved by a British force. A town was laid out in 1784; in 1791 it became a county town ; a borough in 1804; and a city in 1816. In 1906 the citizens of Pittsburg and Al- legheny voted on the question of uniting the two cities. A majority of the citizens of Pittsburgh favored consolidation, but a ma- jority of the citizens of Allegheny voted against it, and subsequently appealed to the courts. In 1907 the U. S. Supreme Court held that the Consolidation Act was valid, and annexation became effective on Dec. 9 of that year. Allegheny is now the North Side of the present Pittsburgh. For years the prob- lem of smoke prevention has engaged the at- tention of municipal officials, and their efforts have resulted in a great improvement in the situation. In 1911 a thorough investigation of the smoke problem, authorized by the city, was undertaken by the Department of Indus- trial Research of the University of Pittsburgh. As a result, the smoke nuisance was abated fully 75 per cent. In 1940 further steps in smoke prevention were taken.
