four o'clock
And once two of the `` big '' Sodality girls came up , assured and laughing and dusty , and boldly performed one of their convent duets . Some of the tired women in the booths straightened up and clapped , and called `` encore ! '' Teresa was not one of these girls . Her instrument was the violin ; moreover , she was busy and absorbed at the Children of Mary 's booth , which by four o'clock began to blossom all over its white-draped pillars and tables with ribbons and embroidery and tissue paper , and cushions and aprons and collars , and all sorts of perfumed prettiness . The two priests were constantly in evidence , their cassocks and hands showing unaccustomed dust . And over all the confusion , Mrs. Costello shone supreme . Her brisk , big figure , with skirts turned back , and a blue apron still further protecting them , was everywhere at once ; laughter and encouragement marked her path .
