sailors believe it is bad luck to change a ship’s name. “let her stay as she was born,” they say. certainly the troubles of the ship amazon began when her name was changed to mary celeste. in 1872, the celeste set sail from new york to england. beneath her decks she carried a cargo of industrial alcohol, which was highly explosive. the seas were calm and the weather was good. everyone expected to be in england within a month.

약간 의아하네요.
