Four new privateers, from 16 to 28 guns each, are just fitted out here; they are compleatly manned, and will in a few days sail on a cruize to intercept the transports expected to arrive in America from England. Yesterday two sloops from Curacoa, laden with powder and warlike stores, arrived safe in this port, and proceeded immediately to land their cargoes. They were chaced on their passage by an English frigate, which was once so near one of them, that she fired a bow-chace gun at her, and killed a negroe man who was at the helm, but the wind dying away, and dark night coming on, the sloops altered their course, when the King's ship lost sight of them.
