`` Ah ! '' smiled Ned , thinking Jimmie was indulging in another of his jokes . `` May I ask when your ship leaves ? '' `` I 'm thinking of leaving about midnight or a little after , '' stated Jimmie , gravely . `` It will depend somewhat on the wind and weather . If it comes on to blow and the sea is rough I believe we 'll get out on time . However , if this breeze should die away , we may not go ! ''
