To this group some writers add Maryland, founded in 1632, because its territory had been claimed by the London Company; but the earliest settlements in Maryland, its principal towns, and almost the whole of its territory, come north of latitude 38° and within the middle zone. [Sidenote: 3. The middle zone.] Between the years 1614 and 1621 the Dutch founded their colony of New Netherland upon the territory included between the Hudson and Delaware rivers, or, as they quite naturally called them, the North and South rivers. They pushed their outposts up the Hudson as far as the site of Albany, thus intruding far into the northern zone. In 1638 Sweden planted a small colony upon the west side of Delaware Bay, but in 1655 it was surrendered to the Dutch. Then in 1664 the English took New Netherland from the Dutch, and Charles II. granted the province to his brother, the Duke of York. The duke proceeded to grant part of it to his friends, Berkeley and Carteret, and thus marked off the new colony of New Jersey. In 1681 the region west of New Jersey was granted to William Penn, and in the following year Penn bought from the Duke of York the small piece of territory upon which the Swedes had planted their colony. Delaware thus became an appendage to Penn's greater colony, but was never merged in it. Thus five of the original thirteen states--Maryland, New York, New Jersey, Pennsylvania, and Delaware--were constituted in the middle zone. As we have already observed, the westward movement of population in the United States has largely followed the parallels of latitude, and thus the characteristics of these three original strips or zones have, with more or less modification, extended westward. The men of New England, with their Portland and Salem reproduced more than 3000 miles distant in the state of Oregon, and within 100 miles of the Pacific Ocean, may be said in a certain sense to have realized literally the substance of King James's grant to the Plymouth Company. It will be noticed that the kinds of local government described in our earlier chapters are characteristic respectively of the three original zones: the township system being exemplified chiefly in the northern zone, the county system in the southern zone, and the mixed township-county system in the central zone.
