g from the Blue Ridge, near the Virginia line, just between the sources of the Yadkin and the Roanoke, in a south-easterly direction some two hundred miles, almost to the sea-coast below Wilmington. In the divide between the first and second systems, which is also the great watershed between the Atlantic slope and the Mississippi Valley, a singular anomaly is presented, for it is formed not by the lofty Smoky range, but by the Blue Ridge--not, therefore, at the crest of the great slope which the surface of the State presents, but on a line lower down.
