Extract of a letter from a young gentleman on board the United States frigate United States, dated Port Mahon, Jan. 23—received in Boston.

Within a few days the commandant has refused giving us our stores from the shore, alledging he had orders from government to charge import and export duty on them, amounting to 4000 dollars. Nothing of this having been mentioned when they were landed, our commodore is determined not to comply.

We have hauled directly opposite the custom-house, with our broadside facing it.

The Constellation is in dock refitting. Captain Gordon's health is not very good. The Erie, Ontario, Alert, John Adams, and schooner Hornet, and the Dutch squadron, are here. The Hornet sails in a few days for Marseilles—and the Adams this day or Gibraltar, to provisions.

The Algerine squadron is in port, and dismantled.

The Algerine brig was demanded by us at Carthagena: but refused till orders were received from Madrid.

The Erie has brought from Algiers, the Americans who were on board the Spanish ship of the line San Fernando, which foundered near there. No property was saved from that ship, she sunk so suddenly. On board her were, 40 or 50 women, soldiers' wives. All the lives were saved; but the Algerines made prisoners of the Spaniards. Every possible exertion was made by the Americans to save the ship.

A letter from Cadiz says, the loss of the San Fernando is a serious one for the Spaniards, and that it was said she had on board 200 men, exclusive of the Americans!
