five o'clock
One of them is keeping Grinnage time , and the other is keeping St. Louis time , like my watch . When we left St. Louis it was four in the afternoon by my watch and this clock , and it was ten at night by this Grinnage clock . Well , at this time of the year the sun sets at about seven o'clock . Now I noticed the time yesterday evening when the sun went down , and it was half-past five o'clock by the Grinnage clock , and half past 11 A.M. by my watch and the other clock . You see , the sun rose and set by my watch in St. Louis , and the Grinnage clock was six hours fast ; but we 've come so far east that it comes within less than half an hour of setting by the Grinnage clock now , and I 'm away out -- more than four hours and a half out . You see , that meant that we was closing up on the longitude of Ireland , and would strike it before long if we was p ` inted right -- which we was n't . No , sir , we 've been a-wandering -- wandering ` way down south of east , and it 's my opinion we are in Africa .
