eight o'clock
For Wetherell had found his tongue at last . After a while Mr. Duncan drew out his watch and gave a start . `` By George ! '' he exclaimed , `` it 's after eight o'clock . I 'll have to ask you to excuse me to-night , Mr. Wetherell . I 'd like to show you the rest of them -- ca n't you come around to-morrow afternoon ? '' Mr. Wetherell , who had forgotten his own engagement and `` Uncle Tom 's Cabin , '' said he would be happy to come .
