The Dutch brig Mercury, 77 days from Marseilles, arrived at Havana on the 16th ult. after having been robbed of $10,000 worth of her cargo, by a piratical schooner and boat, off Cape Antonio.

Fortunately a U. S. vessel has arrived at the scene of these daring robberies, and has already protected two fleets. It is to be hoped some of the villains who have so long preyed with impunity on mercantile property, and been guilty of the most savage acts, will speedily be caught and brought to justice.

U. S. BRIG SPARK.

A letter from a gentleman belonging to this vessel, dated St. Barts, Nov. 3, 1821, says

“We arrived here, after a rather rough passage, in eighteen days from Boston, all well. We expect to sail again in two or three days. We found here the piratical ship which robbed the Orleans Packet. She is now in possession of the Swedish government. She came into their possession in the following manner:—The crew landed her cargo on a small island near this, from whence it was taken by a schooner to St. Thomas;—they then run the ship into Five Island Harbour, where all the crew, except two men, deserted her.—The government hearing of her being there, sent a guard and took possession of her, brought her into this harbour, and confined the two men found in her as pirates.—It is said, Capt. Elton has requested the Governor to allow him to take them to the United States for trial. This piratical ship was originally the U. S. brig Prometheus, which was condemned two years since, and was then sold.”

A letter from on board the Hornet, dated at Cape Maise, 31st, October, says, “The pirate which we took yesterday mounted two long four pounders, and her crew consisted of twenty gallows-looking scoundrels.”—After the capture of the Hornet, spoke three merchant brigs, which probably would have fallen into the hands of the pirates;—and were very happy at their escape.

Piratical Forts.—Captain Sisson, from Havana, reports that seventy of the Pirates belonging to the vessels captured and destroyed by the Enterprize, have erected two forts on Cape Antonio, for their defence.

PIRACY.

In the early part of June I sailed from Philadelphia in the schooner Mary, on a voyage to New-Orleans. My principal object in going round by sea was the restoration of my health, which had been for many months declining. Having some friends in New-Orleans whose commercial operations were conducted on an extensive scale, I was charged with the care of several sums of money in gold and silver, amounting altogether to nearly eighteen thousand dollars. This I communicated to the captain, and we concluded to secure it in the best manner our circumstances would admit. A plank was accordingly taken off the ribs of the schooner in my own cabin, and the money being deposited in the vacancy, the plank was nailed down in its original place, and the seams filled and tarred over. Being thus relieved from any apprehension that the money would be found upon us in case of an attack from pirates, my mind was somewhat easier. What other articles of value I could conveniently carry about with me, I did so. I had also brought a quantity of bank notes to the amount of fifteen thousand dollars. Part of these I caused to be carefully sewed in the left lapel of my coat, supposing that in case of my being lost at sea, my coat, should my body be found, would still contain the most valuable of my effects. The balance was carefully quilted into my black silk cravat.
