When the militia of one county in South Carolina was mustered during the Revolution, it was found that every one of the thirty-five hundred men enrolled were natives of Pennsylvania.

These were mainly sons of North Irishmen, and from the Carolina Irish sprang Calhoun, the most aggressive statesman that has appeared in America, and Jackson, the most brilliant military genius in the whole course of our history.

Before the close of the Revolution this adventurous race had begun to break over the passes of the Alleghanies into the dark and bloody ground of Kentucky and Tennessee.

Soon afterward a multitude of Pennsylvanians of all stocks--the Scotch-Irish and those Germans, Swiss, and Hollanders who are commonly classed together as the Pennsylvania Dutch, as well as a large number of people of English descent--began to migrate down the Ohio Valley.

Along with them came professional men and people of more or less culture, chiefly from eastern Virginia and Maryland.
