"Harsh punishments should never be resorted to. The repressive system may check unruliness, but can never influence for good. It involves little trouble on the part of those who make use of it and may be efficacious in the army, which is composed of responsible adults, but it has a harmful effect on the young, who err more from thoughtlessness than from evil disposition. Far more suitable in their case is the preventive system, which consists in making them thoroughly acquainted with the regulations they have to obey and in watching over them. In this way they are always conscious of the vigilance of the Head-master or his assistants, who are ready to guide and advise them in every difficulty and to anticipate their wants. The pupils should never be left to their own devices, yet they should have complete freedom to run, jump, and enjoy themselves in their own noisy fashion. Gymnastics, vocal and instrumental music, and plenty of outdoor exercise are the most efficacious means of maintaining discipline and improving the boys, bodily and mentally." Only children over seven were admitted to the Institutes founded by Don Bosco. Dr. Barnardo, on the other hand, who rescued thousands of orphans and destitute children in London and was able to witness a decided decrease in the criminality of that capital, concentrated his beneficent efforts on destitute children from their earliest years, with the idea of removing them as soon as possible from the bad environment in which they were born. He was, moreover, desirous that they should share with more fortunate children the boon of happy childhood, and resolved that up to the age of seven they should be brought up without educational or other restraints, save the affection of those appointed to watch over them during the first years, so that they might imbibe sufficient love and joy for the rest of their lives. Such is the rule followed in the buildings set apart for the infants, Bird Castle, Tiny House, and Jersey House, which are perfect nests of happy birds.
