Space does not permit us to describe this movement of colonization.[100:3] The entrance to the fertile limestone soils of the Great Valley of Pennsylvania was easy, in view of the low elevation of the South Mountain ridge, and the watergaps thereto. The continuation along the similar valley to the south, in Maryland and Virginia, was a natural one, especially as the increasing tide of emigrants raised the price of lands.[100:4] In 1719 the proprietor's price for Pennsylvania lands was ten pounds per hundred acres, and two shillings quit-rents. In 1732 this became fifteen and one-half pounds, with a quit-rent of a half penny per acre.[101:1] During the period 1718 to 1732, when the Germans were coming in great numbers, the management of the lands fell into confusion, and many seated themselves as squatters, without title.[101:2] This was a fortunate possibility for the poor redemptioners, who had sold their service for a term of years in order to secure their transportation to America. By 1726 it was estimated that there were 100,000 squatters;[101:3] and of the 670,000 acres occupied between 1732 and 1740, it is estimated that 400,000 acres were settled without grants.[101:4] Nevertheless these must ultimately be paid for, with interest, and the concession of the right of preemption to squatters made this easier. But it was not until 1755 that the governor offered land free from purchase, and this was to be taken only west of the Alleghanies.[101:5] Although the credit system relieved the difficulty in Pennsylvania, the lands of that colony were in competition with the Maryland lands, offered between 1717 and 1738 at forty shillings sterling per hundred acres, which in 1738 was raised to five pounds sterling.[101:6] At the same time, in the Virginia Valley, as will be recalled, free grants were being made of a thousand acres per family. Although large tracts of the Shenandoah Valley had been granted to speculators like Beverley, Borden, and the Carters, as well as to Lord Fairfax, the owners sold six or seven pounds cheaper per hundred acres than did the Pennsylvania land office.[102:1] Between 1726 and 1734, therefore, the Germans began to enter this valley,[102:2] and before long they extended their settlements into the Piedmont of the Carolinas,[102:3] being recruited in South Carolina by emigrants coming by way of Charleston--especially after Governor Glenn's purchase from the Cherokee in 1755, of the extreme western portion of the colony. Between 1750 and the Revolution, these settlers in the Carolinas greatly increased in numbers.
