_York River_ is formed by the junction of the _Mattapony_ and _Pamunky_. Beyond the junction, the Mattapony is navigable for seventy miles; and thirty miles higher up is its source in the Blue Mountains. The Pamunky is formed by the junction of the _North_ and _South Anna_ rivers, which rise in the north-west about fifty miles distant. The mouth of this river is three miles wide; and at high tide there is four fathoms water, twenty-five miles above Yorktown, where it is a mile and a half wide in the wet season, but has a channel of only seventy-five fathoms in the dry season. _James’ River_ is one of the most important rivers in the state of Virginia. It rises in the Alleghany Mountains, near two hundred miles to the west of Richmond; and, after widening and contracting alternately in a very winding course, it enters Chesapeak bay fifteen miles west of Cape Henry; its whole length being three hundred miles. Its principal tributary streams are the Rivanna, the Appomatox, the Chickahomany, the Nansemond, and the Elizabeth, on which last is situated the town of Norfolk. This river, anciently called the _Powhatan_, affords harbor for vessels of any burden, in Hampton Road, seventy miles below Richmond. Vessels of two hundred and fifty tons may go up to Warwick; and those of one hundred and fifty to within a mile of Richmond. The _Roanoake_ is formed by the junction of the _Dan_ and _Staunton_. It runs one hundred and twenty-five miles south-east till it enters Albemarle sound. Its whole course is two hundred miles. It is navigable by sloops sixty miles; the low lands on the banks are subjected to annual inundations. _Cape Fear River_ is the largest in North Carolina. It rises one hundred miles above Fayetteville; and thence running two hundred miles eastward, falls into the Atlantic ocean at Cape Fear, where it is three miles wide, and eighteen feet deep at high tide. It is navigable by vessels drawing ten feet water, up to Wilmington, a little below the confluence of its two principal streams. The _Great Pedee_ rises in the Blue Mountains, on the borders of North Carolina and Virginia, where it has the name of _Yadkin_ river. Its whole course is upwards of three hundred miles, half of which is in North Carolina. It is navigable by ships to Georgetown; and for smaller vessels, one hundred miles higher up. The _Santee_ is the largest river in the state of South Carolina, and is formed by the junction of the _Congaree_ and _Wateree_ rivers. The whole course of the Santee, including that of the Catawbaw or Wateree, is three hundred and fifty miles. It is navigable up to the point of junction by ships of burden.
