Summary

The New International Encyclopædia…

No State in the Union compares with Pennsylvania as to mining. Its mineral wealth has been in a large measure the basis of its diversified and highly developed industrial life. The annual output of coal alone exceeds in value the total mineral product of any other State, and has annually, since 1880, been equal in amount to that of all the coal mined in the other States.

The New International Encyclopædia…

The Mississippi system was of great moment in the early period of development, enabling Pennsylvania to supply the frontier with manufactured products, while the Lake system more recently played a similar important part in rendering accessible vast resources of raw materials. An important network of canals and canalized rivers also figured early, and an elaborate system of railways figured in the later period. Furthermore, the manufacturing interests have been carefully fostered by a number of societies, which owe much to the activities and inspiration of one man, Benjamin Franklin.

The New International Encyclopædia…

No other industry has contributed so greatly to the reputation of the State as that of iron and steel. Although it developed earlier in other colonies, it was spoken of as ‘most advanced’ in Pennsylvania as early as 1756. In 1900 it furnished 54 per cent. of the total product for the United States. The localization of the industry is determined by the accessibility to ore and fuel, and consequently until about 1850 the industry was most extensive in the eastern anthracite coal and iron ore district.
