Remaining in Boston, with little change, until she was thirteen years of age, Mary Pickard was then taken by her parents to Hingham, Massachusetts, to be under the care of the Misses Cushing, whose school for girls enjoyed at that time, and as long as it continued, a very high reputation. Her instructors there, who still live, seem to have regarded her as a friend and companion, rather than a child and pupil; and the fresh recollections and tender love with which they always speak of her, and delight to dwell upon her early and mature character, give us an impression of more than common excellence. This will best be shown by an extract from a letter written since her death to one of her children. "Your dear mother came to us first in June, 1811; a sweet, interesting girl, thirteen years old, tall for that age, and with the same sweet expression of countenance she ever retained; remarkable even then for her disinterestedness and forgetfulness of self, and her power of gaining the love of all around her. She went home in November of the same year, and returned to us again in 1814.... She was with us but little more than one year in the whole, and in that short period endeared herself to us in a remarkable manner. For with the love which we could not but feel for her was mingled a respect and admiration for her high principles, and the piety which shone through all her conduct, in a degree very uncommon for a girl of her age. As a scholar she was exceedingly bright, and quick to comprehend, and would, I always thought, have made an excellent mathematical scholar, had she pursued the study of that branch. Her capacity for accomplishing a great deal in a short time was always remarkable, and I believe she never undertook any thing that she thought worth her attention, that she did not go through to the satisfaction of others, if not of herself. Her chief object, even when a young girl, seemed to be to do good, in some way or other, to her fellow-beings, and she considered nothing too difficult for her to undertake, if it could benefit another person either in a temporal or moral view. You have had sufficient evidence of this, since you have been old enough to judge for yourself, and I can only tell you that it seemed to be, at an early period of her life, a living principle with her. Yet, with all this devotedness to the highest objects and purposes of our existence, she was one of the most lively and playful girls among her companions, and a very great favorite with them all."
