Affairs in Gloucester.
[Correspondence of the Richmond Dispatch.]The gunboats continue their usual voyages up York over as far as West Point. Last week a deserter, named Woodard, from the Gloucester Light Dragoons, escorted by several marines, burnt a barn, filled with grain, belonging to Lieut Leavitt, of same company.
Large fleets of Eastern vessels are busily engaged stealing oysters, Brig Gen. Wistar, commanding at Yorktown, informs the citizens that for every vessel that is destroyed by our troops he (Gen Wistar) intends retaliating by applying the torch to some peaceful dwelling located on the river. Surely the condition of the Gloucester people is heart-rending.
