four o'clock on Monday
`` I fear they would prove failures ; better wait a more favorable light . '' As though to tantalize frail humanity , `` Old Sol '' remained very exclusive all day , and , even though Helen remained till evening in the hope that he would overcome his fit of sulks , nothing of the kind happened , and she was forced to go back to the school without one . `` Just wait till Monday , and we 'll do wonders ; see if we do n't , '' said Jean , as she bade her farewell , little dreaming what wonders she was destined to do with her magical box ere the sun set Monday night . `` I 'll ask Miss Preston to let me come over at four o'clock on Monday , and then we 'll go out in the little dell and get a lovely picture . You know the place I mean : where that old clump of fir-trees stands by the ruined wall , '' said artistic Helen . But when Monday arrived unforeseen difficulties arose for Jean . The day was the sunniest ever known , and , while waiting for Helen to come , she got out the precious camera to set the plates .
