Mary Ann Bloomfield is six years old. She is the second oldest of the Bloomfield children. She is no better as a student than her brother. Instead of doing her lessons, she will lie on the floor and refuse to do anything. Agnes is also in charge of Mary Ann's dress, another aspect of life in which the girl is uncooperative. She refuses to let Agnes wash her, or refuses to wear the clothes Agnes has prepared for her. She also fidgets while Agnes tries to fix her hair, making the process take longer than necessary. As with Tom, the Bloomfields believe that Agnes should be able to make Mary Ann do as she is told, even without being allowed to punish the child.
