I have yet to speak of the duties of older to younger brothers and sisters. If it is difficult to serve two masters, it is hardly pleasant to be asked to serve half a dozen. The youngest children in a large family are often placed in this position. There is, in the first place, the authority of the parents, which must be respected; then, in addition, each of the grown-up sons and daughters is apt to try to exercise a little authority on his or her own account. The younger ones naturally resent this petty despotism, and disobedience and angry recriminations are the unpleasant consequences. It is often necessary that elder sons and daughters should have partial charge of the younger. They can in all cases make their authority acceptable by representing it as delegated, by having it understood that they regard themselves merely as substitutes in the parents' place. There must be unity of influence in the home, or else the moral development of the young will be sadly interfered with. There must be only a single center of authority, represented by the parents, and all minor exercise of authority should be referred back to that center. "Father and mother wish me to help you"; "Father and mother will be pleased if you do so and so; let me try to show you how"--if the method of management implied in such words as these be adopted, the younger children will look upon the elder as their friends and be glad to accept advice and direction. Lastly, a word about the relation between brothers and sisters, and conversely. This relationship is qualified by the difference of sex. A certain chivalry characterizes the attitude of the brother toward the sister, a certain motherliness that of the sister toward the brother. The relation may be and often is a very beautiful one. The peculiar moral responsibility connected with it is that the sister is usually the first woman whom the brother knows at all intimately and as an equal, and that his notions of womanhood are largely influenced by the traits which he sees in her, while the brother is usually the first man whom the sister knows as a companion, and her ideas of men are colored by what she sees in him.
