From Havana and Key West.
--We are indebted to the Captain of a vessel, which arrived yesterday evening from Havana, for late Northern papers. She brings an assorted cargo, consisting of coffee, tea, soda ash, lead, kerosene oil, &c. She had a good run from Havana, making the fleet off Pensacola at 10 o'clock yesterday morning. She gave them a wide berth, and favored by a strong southwest wind, came a kiting through the swash, rounding Mobile Point at twenty minutes past two o'clock.The fleet off Pensacola consisted of eighteen sail--two square rigged, the rest apparently mortar vessels. Passed the Miramon ten miles out from Havana, bound in, and another Northern steamer, painted green, a few hours afterwards.
From a passenger on board recently from Key West we learn that the conversation there was of a simultaneous attack upon Fort Pulaski and New Orleans. The Federals expected something from their large vessels, but not much from the mortar boats, one of which, in some experimental firing at Key West, ‘"shook herself to pieces."’ It was the understanding there that the Virginia was victualed and supplied with ammunition for a long cruise, and great fears were entertained that she would visit that port. The vessels at Key West were the Niagara, the Mohawk, and two other inferior steamers, and a few transports. A few days before our informant left, Captain Campbell, of the Malory, and four Key West Secessionists, has given the Federals the slip, leaving in an op- boat.--Mobile Advertiser.
