`` No school to-day . We 'll have a holiday . '' `` We 'd better wait a little while , '' said Agnes Evans , who was the eldest as well as the brightest pupil in the school . `` Professor and Mrs. Horner may come in any minute ; we 'll wait till ten o'clock . Come here , little sobersides , '' she said to Edna . `` What are you so solemn about ? What word did your aunt and uncle leave ? ''
