Letters from Gibraltar by the Minerva, Capt. Calhan, who is arrived at Portsmouth, bring advice, that a vessel was put in there from Cadiz; and the master reports, that two days before he left that place three vessels loaded with wheat, and other things, the produce of America, arrived in that port; that he was informed, that the Spaniards carried on a considerable trade with the Americans; and that they took but a few goods in return, but were generally paid in hard dollars.
