[68:1] For the settled area in 1660, see the map by Lois Mathews in Channing, "United Stales" (N. Y., 1905), i, p. 510; and by Albert Cook Myers in Avery, "United States" (Cleveland, 1905), ii, following p. 398. In Channing, ii, following p. 603, is Marion F. Lansing's map of settlement in 1760, which is on a rather conservative basis, especially the part showing the interior of the Carolinas. Contemporaneous maps of the middle of the eighteenth century, useful in studying the progress of settlement, are: Mitchell, "Map of the British Colonies" (1755); Evans, "Middle British Colonies" (1758); Jefferson and Frye, "Map of Virginia" (1751 and 1755). On the geographical conditions, see maps and text in Powell, "Physiographic Regions" (N. Y., 1896), and Willis, "Northern Appalachians," in "Physiography of the United States" (N. Y., 1896), pp. 73-82, 169-176, 196-201. [70:1] See Osgood, "American Colonies" (N. Y., 1907), iii, chap. iii. [70:2] See chapter ii, _ante_.

Y., 1904), i, chap. xi; and Egleston, "Land System of the New England Colonies," Johns Hopkins Univ. _Studies_ (Baltimore, 1886), iv. Compare the account of Virginia, about 1696, in "Mass. Hist. Colls." (Boston, 1835), 1st series, v, p. 129, for a favorable view of the New England town system; and note the probable influence of New England's system upon Virginia's legislation about 1700.
