nine o'clock at night
`` When is the next sailing for Alaskan ports ? '' asked Dick . `` Our sailing , as I told you before , is day after to-morrow . But one of the other lines has a sailing to-morrow , at nine P. M. '' `` They all seem to sail at nine o'clock at night , '' mused Sam . `` Yes , that is the usual hour , '' answered the clerk . `` Well , if we have to , we can take that boat at nine o'clock to-morrow night , '' remarked Dick . `` Provided you can get accommodations , '' said the clerk .
