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.
