In regard to the intellectual training of young children, some modification in the common practice is necessary, with reference to their physical well-being. More care is needful in providing _well-ventilated_ school-rooms, and in securing more time for sports in the open air during school hours. It is very important to most mothers that their young children should be removed from their care during certain school hours; and it is very useful for quite young children to be subjected to the discipline of a school, and to intercourse with other children of their own age. And, with a suitable teacher, it is no matter how early children are sent to school, provided their health is not endangered by impure air, too much confinement, and too great mental stimulus, which is the chief danger of the present age. In regard to the formation of the moral character, it has been too much the case that the discipline of the nursery has consisted of disconnected efforts to make children either do, or refrain from doing, certain particular acts. Do this, and be rewarded; do that, and be punished; is the ordinary routine of family government. But children can be very early taught that their happiness, both now and hereafter, depends on the formation of _habits_ of submission, self-denial, and benevolence. And all the discipline of the nursery can be conducted by parents, not only with this general aim in their own minds, but also with the same object daily set before the minds of the children. Whenever their wishes are crossed, or their wills subdued, they can be taught that all this is done, not merely to please the parent, or to secure some good to themselves or to others; but as a part of that merciful training which is designed to form such a character, and such habits, that they can hereafter find their chief happiness in giving up their will to God, and in living to do good to others, instead of living merely to please themselves. It can be pointed out to them, that they must always submit their will to the will of God, or else be continually miserable. It can be shown how, in the nursery, and in the school, and through all future days, a child must practice the giving up of his will and wishes, when they interfere with the rights and comfort of others; and how important it is early to learn to do this, so that it will, by habit, become easy and agreeable. It can be shown how children who are indulged in all their wishes, and who are never accustomed to any self-denial, always find it hard to refrain from what injures themselves and others. It can be shown, also, how important it is for every person to form such habits of benevolence toward others that self-denial in doing good will become easy.
