Yankees in King George and Westmoreland.
A correspondent, writing from Port Royal under date of the 21st, states that the Yankees have withdrawn their pickets from Port Conway, just opposite Port Royal; but scouting parties appeared there almost daily. A courier had just arrived, bringing information that five Yankee gunboats had come up to Layton's Ferry, in Westmoreland, about 15 miles below Port Royal. He also stated that about 1,000 Yankee cavalry were encamped in Westmoreland, just opposite Layton's, and that they were committing many depredations upon the country adjacent to that point.
