Last Week a small Privateer, belonging to Bristol, seized a Sloop at Nantucket, and convoyed her to a safe Port. She was from New-York, and had taken on board, at Nantucket, a large Quantity of valuable Houshold Furniture, &c. the Property of Frederick William Geyer, a Boston Tory, who fled from that Place to Halifax with the British Fleet, and has since taken up his Residence at New-York.
