Early colonial iron mills were operated by the Germans, whose muskets, made in Nazareth, Pa., were used by the continental troops. In later years, the Poles and Slavs have labored in the great steel mills of Ohio, Pennsylvania, Indiana, and New York. It is the endurance and physical heritage of these sturdy people that have made it possible for us to lead the world in the production of steel.

Coal
The Welsh with the Scotch-Irish were the first to develop our coal mines in Pennsylvania and West Virginia. These, together with the English, Irish, Germans, Poles, and Slavs, have made us the chief coal producer of the world.
