Summary

The New International Encyclopædia…

The Pittsburg coal district, embracing an area of 14,000 square miles, is the richest coal field in the world. It is from the excessive consumption of coal in its mills and furnaces that Pittsburg derives its sobriquet, “The Smoky City.” As a manufacturing city Pittsburg is best known, and until recent years it possessed all of the unattractive characteristics of such a community. Recently, however, great progress has been made, and fine streets, splendid boulevards, a system of parks, costly residences, and other evidences of municipal and civic pride have come into existence.

The city's rapid growth, however, is due to its industrial activities, and these owe their supremacy to the abundant fuel supply. Coal and coke form the largest items in the immense freight tonnage of Pittsburg, a tonnage which surpasses that of New York and Chicago combined, and which has no equal in the world. The railroad freight for 1902 exceeded 80,000,000 tons, while the water tonnage approximated 9,500,000 tons. The manufacturing interests of the city date back to the close of the eighteenth century.

Natural and artificial gas is piped to all parts of the city. For a decade previous to 1895 natural gas was the principal fuel in the mills and factories, but, owing to a decrease in the supply, the larger factories have been forced to resume the use of coal. Natural gas still forms the favorite fuel for domestic purposes. An extensive system of street railways, operated by electricity, connects the city with the surrounding towns. All the lines in Pittsburg and Allegheny and many of those reaching to the boroughs have been consolidated under one management.
