The vessel on board which we found ourselves was a large, handsome craft, of fully a hundred and eighty tons; and, from her great beam, her taunt, raking masts, the broad white ribbon outside, and the peculiar paint and fittings on her deck, she was evidently American.  There were a good many white men among her crew; but there were also many blacks and mulattoes, of every shade of brown and hue of olive or copper. Never had I seen people of so many nations and tribes brought together, while every one of them to my eyes appeared most villainous cut-throats.
