In Massachusetts, the westward movement is recorded in the founding of Springfield in 1636 and Great Barrington in 1725. By the opening of the eighteenth century the pioneers of Connecticut had pushed north and west until their outpost towns adjoined the Hudson Valley settlements. In New York, the inland movement was directed by the Hudson River to Albany, and from that old Dutch center it radiated in every direction, particularly westward through the Mohawk Valley. New Jersey was early filled to its borders, the beginnings of the present city of New Brunswick being made in 1681 and those of Trenton in 1685. In Pennsylvania, as in New York, the waterways determined the main lines of advance. Pioneers, pushing up through the valley of the Schuylkill, spread over the fertile lands of Berks and Lancaster counties, laying out Reading in 1748. Another current of migration was directed by the Susquehanna, and, in 1726, the first farmhouse was built on the bank where Harrisburg was later founded. Along the southern tier of counties a thin line of settlements stretched westward to Pittsburgh, reaching the upper waters of the Ohio while the colony was still under the Penn family. In the South the westward march was equally swift. The seaboard was quickly occupied by large planters and their slaves engaged in the cultivation of tobacco and rice. The Piedmont Plateau, lying back from the coast all the way from Maryland to Georgia, was fed by two streams of migration, one westward from the sea and the other southward from the other colonies--Germans from Pennsylvania and Scotch-Irish furnishing the main supply. "By 1770, tide-water Virginia was full to overflowing and the 'back country' of the Blue Ridge and the Shenandoah was fully occupied. Even the mountain valleys ... were claimed by sturdy pioneers. Before the Declaration of Independence, the oncoming tide of home-seekers had reached the crest of the Alleghanies." [Illustration: DISTRIBUTION OF POPULATION, 1790] Beyond the mountains pioneers had already ventured, harbingers of an invasion that was about to break in upon Kentucky and Tennessee. As early as 1769 that mighty Nimrod, Daniel Boone, curious to hunt buffaloes, of which he had heard weird reports, passed through the Cumberland Gap and brought back news of a wonderful country awaiting the plow. A hint was sufficient. Singly, in pairs, and in groups, settlers followed the trail he had blazed. A great land corporation, the Transylvania Company, emulating the merchant adventurers of earlier times, secured a huge grant of territory and sought profits in quit rents from lands sold to farmers. By the outbreak of the Revolution there were several hundred people in the Kentucky region. Like the older colonists, they did not relish quit rents, and their opposition wrecked the Transylvania Company. They even carried their protests into the Continental Congress in 1776, for by that time they were our "embryo fourteenth colony."
