Local health machinery should guarantee protection against the evils mentioned in preceding chapters. In general, one man is better than three to execute, although three may be better than one to legislate. Where small communities do not wish to have the entire state sanitary code rigidly administered, they can adopt New York's method of a legislative board of three members, headed by an executive, whose business it is to act, not talk; to watch subordinates, and to enforce rigidly and continuously ordinances passed by the board. The National Bureau of Census places under the general heading Health and Sanitation the following activities: health administration, street cleaning and refuse disposal, sewers and sewage disposal. Sanitarians generally emphasize also the health significance of efficient water service. A community's health programme should be clearly outlined in the annual budget. Where health work is given funds without specification of the kinds of work to be done, serious evils may be overlooked and lesser evils permitted to monopolize the energies of health officers. Again, after money has been voted to prevent an evil, records should be made of work done when done, and of money spent when spent, so that any diversion will be promptly made known. The best present guides to budget making, to educational health reports, and to records that show efficiency or inefficiency of health administrators are the budget and report of the department of health for New York City, and the story of their evolution told in _Making a Municipal Budget_, by the Bureau of Municipal Research. To find out whether local machinery is adequate, the reader must enumerate the things that need to be done in his community, remembering that in all parts of the United States to-day there are sanitary laws offering protection against dangers to health, excepting some dangers not understood until recently, such as child labor, dangerous trades, lack of safety devices. Adequate local protection, however, will not become permanent until adequate state machinery is secured. State health machinery should be of two kinds,--fact-gathering and executive supervision through inspection. The greatest service of state boards of health is to educate localities as to their own needs, using the experience of all communities to teach each community in how far its health administration menaces itself and its neighbors. In addition to registration of contagious diseases, facts as to deaths and births should be registered. State health boards should "score" communities as dairies and milk shops are now being scored by the National Bureau of Animal Industries and several boards of health. When communities persist in maintaining a public nuisance and in failing to enforce health laws, state health machinery should be made to accomplish by force what it has failed to accomplish by education.
