Yet the first distinctive American frontier was not created alone by the movement of population westward from the older settlements; like every successive frontier in our history, it became the mecca of emigrants from British and continental lands. Before 1700, exiled Huguenots and refugees from the Palatinate began to seek the New World; and during the eighteenth century men of non-English stock poured by the thousands into the up-country of Pennsylvania and of the South. In 1700 the foreign population in the colonies was slight; in 1775 it is estimated that 225,000 Germans and 385,000 Scotch-Irish, together nearly one fifth of the entire population, lived within the provinces that won independence. Persecution and the ravages of war, taxes that were heavy at any time and intolerable in time of famine, were among the causes that disposed many thousands of Protestant families from Ulster, and from the thickly populated districts of Switzerland and the Rhine country, to seek new homes in a land of better promise. To cross the ocean was no slight undertaking for unlettered and home-keeping people. But since the founding of Pennsylvania knowledge of America had spread among the peasants of Germany, and there was no lack of "Neulanders"--the emigrant agents of that day--who described the New World in glowing terms, and stood ready for a consideration to carry any who wished to be transported to its shores. And the way was facilitated by the English and colonial Governments: to forestall the French in settling the interior, secure the trade of the Indians in time of peace, and erect a barrier against them in time of war, foreigners were accorded naturalization, land was offered on easy terms, and toleration granted to all Protestant sects.
Foreigners were not attracted to New England, where the Puritans scrutinized all newcomers with a jealous eye; while New York was avoided on account of the unhappy experience of Governor Hunter's Palatines and the refusal of the great landowners along the Hudson to grant freehold title. Most of the Germans, seeking homes in the best advertised and most German of all the colonies, landed at the port of Philadelphia. Germantown had been founded by Francis Daniel Pastorius in 1683, but it was not until forty years later, after the devastating wars of the Spanish Succession, that his countrymen occupied in force the neighboring counties of Lancaster, Montgomery, and Bucks, pushed up into Lehigh and Northampton, and across the Susquehanna into Cumberland and Adams. Much to their surprise, doubtless, for it was scarcely the business of the emigrant agent to inform them, they learned that land in this German mecca sold for from £10 to £15 per hundred acres, and bore a quit-rent of one halfpenny. Many occupied the land as squatters, and it is estimated that 400,000 acres were settled without title between 1732 and 1740. But the newcomers or their children soon learned of better opportunities to the south, where Maryland land sold for from £2 to £5 per hundred acres, and the up-country forestallers, such as Carter and Beverley, under-sold the Pennsylvania land office in order to attract settlers. As early as 1726 the stream of German migration began, therefore, to move along the mountain slopes to the south and west. During the middle decades of the century, they occupied in increasing numbers the Piedmont of Virginia, crept southward along the west side of the Blue Ridge in the Shenandoah Valley, and out into the up-country of the Carolinas west of the great Pine Barrens.
