eleven o'clock
`` Who knows ? '' replied Mr. Fogg , entering the car as coolly as ever , and commenced to reassure Mrs. Aouda , by telling her that braggarts need never be feared . He then asked Fix to be his second in the approaching duel , which Fix could not well refuse to be ; and then Phileas Fogg sat down quietly and resumed his whist , without betraying the least emotion . At eleven o'clock the whistle of the engine announced their approach to Plum Creek . Mr. Fogg got up , and followed by Fix and Passe-partout , carrying a brace of revolvers , went out upon the platform . Mrs. Aouda remained in the car , as pale as death . At that moment the door of the next car opened , and Colonel Proctor appeared , followed by his second , a Yankee of the same stamp as himself .
