As for parochial and private schools, they may resent for a time public supervision of their hygiene teaching and practice. However, the case could be so presented that they would ask for it, because it would help not only their pupils and society but the schools themselves. No religious belief or private investment can afford to admit that it disregards child health; state supervision would require nothing more than evidence of adequate school hygiene. 11. _Information gained at school regarding conditions prejudicial to community health should be published and made the basis of an aggressive campaign for the enforcement of sanitary laws._ Ten thousand uses can be made of the information gained at school, ten thousand forces can be made to do educational work, but only a few kinds of work can be done effectively at school. Franklin Ford has said: "You can relate school to all life, but you cannot bring all life under the school roof." As Chapters XVI-XVIII make clear, to socialize the point of view of dispensaries and hospitals is more effective than to put clinics in school buildings. To _do for_ or _give to_ people who can help themselves is to _give up_ and _do up_ power of self-help. Machinery that must some day exist for the execution of this programme will be approximately the following: I. NATIONAL MACHINERY 1. Clearing house for facts regarding school hygiene as taught and practiced in all schools under the Stars and Stripes; this to be a part of the National Bureau of Education. 2. Scientific research to be conducted by the National Bureau of Education or by the future National Board of Health. II. STATE MACHINERY 1. Clearing house for facts regarding school hygiene taught and practiced in all schools within state limits; this to be maintained by the state educational authorities. 2. Agents to make special inquiries as to practice and teaching of school hygiene. 3. Agents to inspect and to instruct county superintendents, county physicians, teachers, normal schools, etc. 4. A bureau of experts--architect, sanitarian, teacher--whose approval must be obtained before any school building can be erected. (A plan which brought excellent results when applied by state boards to charitable institutions, hospitals for the insane, etc.) 5. Standard making by normal schools, state universities, hospitals, or other educational and correctional institutes under direct state management. III. COUNTY MACHINERY 1. Clearing house for facts regarding school hygiene taught and practiced in all schools within county limits; this to be maintained by the county superintendent of schools. 2. Physician and nurse to organize inspection and instruction for rural schools, to give lessons and make demonstrations at county institutes, to show teachers how to interest physicians, dentists, health officers, and parents in the physical welfare of school children.
