A steam frigate off the Bar.
--At an early hour this morning a large steam frigate made her appearance off this harbor, and for some time there was much speculation as to her nationality, but about mid-day the steamer Charleston
took on board a party of gentlemen, and proceeded outside the port for the purpose of finding out the character of the vessel.

, Commodore Stringham
, which vessel has come here to enforce the blockade.
is a frigate of the first class, and is heavily armed.
She was built at the same time of the Niagara
, Wabash, Roanoke
, &c.--Charleston (S. C. ) News, May 29
