twelve o'clock
`` I have n't counted , '' said Jimmy , laughing . `` I tell you what , mother , we must celebrate Jimmy 's birthday . He is the only artist in the family , and we must treat him with proper consideration . I 'll tell you what , Jimmy , I 'll close up my business at twelve o'clock , and give all my clerks a half-holiday . Then I 'll take you and mother to Barnum 's Museum , where you can see all the curiosities , and the play besides . How would you like that ? '' `` Ever so much , Paul , '' said the little boy , his eyes brightening at the prospect .
