one o'clock
So , after recess , Miss Lawrence had to make a rule that books could not be used as playthings , even at recess times . For the rest of the morning , Marjorie was a model pupil . She studied her lessons for the next day , and though Miss Lawrence glanced at her from time to time , she never saw anything amiss . But when school was over at one o'clock , Marjorie drew a long breath and fairly flew for her hat . `` Good-bye , dearie , '' said Miss Lawrence , as Midge passed her when the long line filed out . `` Good-bye ! '' was the smiling response , and in two minutes more Mopsy was skipping and jumping across the playground .
