Society is so organized that the treatment of serious physical defects and social needs at school would upset the machinery a very great deal. For the school to do for its children whatever they may need during their school years will require the setting up of a miniature society in every school building or under every school board. Unless schools are to equip themselves to take the place of all existing facilities for relief and surgery, children would not be so well taken care of as at present. It should not be forgotten that the physical welfare of the school child is the most accurate index to the physical needs of the community. After all, the child lives for six important years before coming to the school and leaves at the early age of fourteen or fifteen; even while attending school it sleeps at home and is influenced more by home and street standards of ventilation, cleanliness, and morality than by conditions at school. It would seem, therefore, the wider use of the school's influence to use the child's appeal to strengthen every agency having to do with community health, rather than to concentrate upon the child himself. If babies were properly cared for up to the sixth year, the protection of the school child's health would be infinitely easier. To take our eyes from the child not yet in school and from the child just out of school is to make the mistake that so many advocates of the child labor movement have made of going whither and only so far as our interest leads us and of not continuing until our work is accomplished. [Illustration: "DOING THINGS" THROUGH MODEL TENEMENTS] Do we want to make of our schools miniature hospitals, dispensaries, relief bureaus, parks? Or shall we use the momentum of society's interest in the school child to put within the reach of every school building adequate hospitals, dispensaries, relief centers, and parks for school child and adult? Shall every little school have its library, or shall the child be taught at school how to use the same library that is available to his parents and older brothers and sisters? If the library is to be under the school roof, if dispensary and relief hospital are to be conducted on the same site as the school, shall they be known as dispensary, library, relief bureau, each under separate management, or shall they be known as school under the management of school principal and superintendent? So complicated and many-sided is the problem of working together with one's neighbor for mutual benefit that it is a safe rule for the schools to adopt: _We shall do nothing that is unnecessary or extravagant. We shall have done our part if we do well what no one else can do. Whatever any agency can do better than we, we shall leave to that agency. Work that another agency ought to have done and has left undone, we shall try to have done by that agency._
