PHILADELPHIA, Dec. 14.

Extract of a letter from New York, dated Dec. 13.

"This morning arrived here the sloop Roebuck, captain Dawson, in 52 days from Gibraltar. Capt. Dawson informs us, that on the 11th of October a great bustle took place on board the English squadron at Gibraltar—they were continually employed day and night, taking in provisions and water for a 6 months' cruise. When completed, they sailed up to the east, with a strong head wind, consisting of six 74's and a brig—their destination was unknown.

When captain Dawson was coming out he met an English cutter with dispatches for Gibraltar. There had not, captain D. informs us, been convoy given to American vessels for 12 weeks. That two Swedish vessels had been taken off Cape Palos, the last of September by a Tripolitan cruiser. That on the 12th September the Tripolitans at Gibraltar, applied to the Governor (Prince Edward) for permission to stop the frigate Adams from leaving the port, which he refused to do, and gave notice of it to captain Campbell, who at 6 o'clock, P. M. that day, got his frigate under way, and has since continued cruising between Gibraltar and Algeciras: That on the 16th of October the Tripolitans obtained a passport from the Emperor of Morocco which was signed by all the christian Consuls in his dominions, in order to obtain a release from blockade of the Tripolitan cruisers at Gibraltar. They were preparing for sea, and it was expected that they would not be molested by the American squadron, on the ground that any hostile measures on the part of the American squadron, would be a cause of a declaration of war against the United States by the Emperor of Morocco.

That on the 18th of Oct. an English Cutter of 14 guns, blew up at Gibraltar, which was caused by two boys carelessly playing with a candle, who unfortunately perished. This information was obtained from an officer of the ship Molly, of Philadelphia, condemned by the Spanish Government.

The Roebuck spoke Dec. 5 schooner Francis Nixon, 2 days from Philadelphia, for Jamaica. Left at Gibraltar, brig Molly, of Marblehead, for New York, Snow Polly, Graves, of Philadelphia, for do. schr. John, Birchmore, of Salem, waiting for convoy up the Straights; brig Naucies, Flemming, of N. York, for Naples; brig Syren, Patterson, sailed—for Leghorn on the 15th inst. without convoy."
