`` I want to find out what is planned in the tests that are to take place here . '' `` The members of the board , '' replied Mr. Rhinds , `` are the three men , in citizen dress , who are at the sixth table down from here . They came into their dinner about ten minutes ago . As to to-morrow , I can tell you that , beginning at eleven o'clock , all the submarine boats entered are to take a straight , out-to-sea speed sail for six hours . The gunboat , ` Chelsea ' will start the fleet , and the ` Oakland ' will go along with the racers . '' `` That 's short time for us , '' muttered Mr. Farnum , uneasily . `` Luckily , sir , we 're ready , at a single moment 's notice , '' interposed Captain Jack Benson .
