Letters from South Carolina, brought by a ship that is arrived at Nantz, mention, that on the 8th of April last, four large ships were then loading at Charlestown with indigo and rice, for a foreign market, they mounted from 20 to 30 guns; and that a transport, laden with porter, had been brought into [South] Carolina by two American privateers, who had taken the cargo out, and were then proceeding to fit her as a privateer, being a very good ship.
