Our chance encounter with the brigantine thus ended satisfactorily enough, so far as we were concerned.  However, it was not until the next morning that the weather had moderated sufficiently to enable us to take possession of our prize, when we found that we had captured a very smart vessel of two hundred and sixty-five tons measurement, with a cargo of three hundred slaves on board, bound for Havana.  I lost no time in turning her over to Jack Keene, with a prize crew of twelve men, with instructions to take her into Port Royal for adjudication, and to await there the arrival of the schooner.  Before parting company I seized the opportunity to question the crew of the _San Antonio_ as to the brig of which I was in search, but they professed to know nothing whatever of her.
