Every child should be taught to give courteous recognition to acquaintances. The boys should lift the cap to each other as well as to their elders, always to father and mother, if they chance to meet them on the street; and the girls by some modest feminine salute of bow or word. But some one may object that it seems “far-fetched” to train boys to this formal mannerism. To which I reply in the old adage that the “boy is father of the man.” The man in every relation in life will follow the lead of boyish habits unless indeed in the interests of some great conviction or self-interest he makes all things new. This can be done, but even then the traces of early habits will often remain to bring shame and confusion at some critical point when pleasure or profit are at stake. III. The social life of boys and girls should be recognized and provided for as a department of the school in which they shall become educated in those things which make for social righteousness and purity later on. As boys treat each other, they will, as a rule, treat each other as men. As boys and girls behave toward each other, so will they as a rule behave as men and women. Courtesy is necessary to the highest degree of success in any enterprise. The boy who is habitually courteous toward other boys will be successful in winning his way as a man among men with any important message with which he may be commissioned; and if he is so instructed that he is gentle, considerate, and true to his mother, sisters, and girl associates, he will be a safe friend as a man, a representative of Christ to his own wife and children, and help to make that home which must stand as a witness for God in the last days. The children in whose interests I am writing must be in a peculiar sense messengers of light to the world. They will be on the field of action in the very last scenes of the earth’s history, when souls must be _snatched_ by a power of which we have little comprehension—the power to _win quickly_; the power to reveal the truth as in a flash of light, so that it will be recognized at sight by the bewildered, desperate soul that has awakened at the last moment to its peril and privilege, and with scant space for repentance and cleansing, cries out for help; and the Holy Spirit must find somewhere those whom he can train and use for the service which in those days must be done to reach _every_ creature, high as well as low, with the gospel. The truth is worthy of the best possible investment. Its messengers should be free from every offensive habit, custom, and manner—thoroughly equipped in all that is most graceful, most scholarly, as genuine Christian scholarship goes; most refined, most chaste, and agreeable in both public and private intercourse. They should be the most suitably, and that means the most simply and tastefully, dressed.
