Even such accomplishments as music and painting are most cultural when pursued as if the intention of the student were to teach them. Knowledge of technique and of the methods by which its difficulties are overcome is the foundation of all appreciation of art. The only true connoisseur is the one who can enter into the delight felt by the artist in creating his work. Exercise leads to invention. The ancients well said that the contortions of the sibyl generated her inspiration. Critics have been sneeringly defined as "those who have failed in literature and art," but this is not true of the greatest critics, who never carried their creative work to the point of success simply because they had found a better vocation in criticism before reaching such a point. What a loss to the world it would have been had Ruskin developed into a painter, even a great one, instead of the master interpreter and teacher of painting that he did become! Household employments, such as cooking, needlework, etc., as vocations for the unmarried woman, no less than the married, need only be mentioned here, as their appropriateness for the girl at home is obvious, and they are fully discussed elsewhere in this series. It should be suggested, however, that the greater leisure of the unmarried woman enables her to try experiments in these subjects while the married housewife is too fully occupied by the routine of her duties to undertake them. Indeed, if a woman become a notable cook after marriage, it is often a sign that she is not a notable wife or mother. It is an old saying that, "My son's my son till he gets him a wife, But my daughter's my daughter all her life." By the common bond of sex, a daughter is her mother's natural companion in sympathy, however separated from her in distance. Therefore, when she lives at home, what a special obligation is there to be her mother's comfort and dependence! Even though she acquire greater skill in household affairs, she should still resign herself to the subordinate place of assistant. The thought that she is becoming useless is the chief dread of a woman who has been a managing worker all her life, and her daughter should carefully avoid bringing this to her mind, indeed, should so act that the ageing mother retains the management of the house, even though her labors diminish. In respect to the direction of children, the elder daughter should take a hint from the manner in which the school-teacher supplements rather than supplants the mother in her care of the young people, leading to a difference in the kind of regard which these feel for them. The sister should always consider herself simply as the eldest, most experienced of the children, and so the natural monitor of the group, and, when necessary, the mediator with the parents.
