ight air,
children cannot follow advice to sleep with windows open. Unless the
family cooeperates in making definite plans for the use of toilet and
bath for each member, constipation and bad circulation are sure to
result. Indigestion is inevitable if employees are not given lunch
periods and closing hours that permit of regular, unhurried meals.
Cleanliness of person costs more than it seems to be worth where cities
fail either to compel bath tubs in rented apartments or to erect public
baths. A temperate subsistence on adulterated, poisonous, or drugged
foods might be better for one's health than gormandizing on pure foods.
No recipe has ever been found for bringing up a healthy baby on
unclean, infected milk; for avoiding tuberculosis among people who are
compelled to work with careless consumptives in unclean air; or for
making a five-story leap as safe as a fire escape. Perfect habits of
health on the part of an individual will not protect him against
enervation or infection resulting from inefficient enforcement of
sanitary codes by city, county, state, and national authorities.

ROUTINE FOR BABIES]

The "municipalization" or "public subsidy" of health habits is
indispensable to protecting industrial efficiency. Public lavatories,
above or below ground, have done much to reduce inefficiency due to
alcoholism, constipation of the bowels, and congestion of the kidneys.
Theaters, churches, and assembly rooms could be built so as to drill
audiences in habits of health instead of fixing habits of uncleanly
breathing. Street flushing, drinking fountains, parks and breathing
spaces, playgrounds and outdoor gymnasiums, milk, food, and drug
inspection, tenement, factory, and shop supervision, enforcement of
anti-spitting penalties, restriction of hours of labor, prohibition of
child labor,--these inculcate community habits of health that promote
community efficiency. It is the duty of health boards to compel all
citizens under their jurisdiction to cultivate habits of health and to
punish all who persistently refuse to acquire these habits, so far as
the evils of neglect become apparent to health authorities. The
unlimited educational opportunity of health boards consists in their
privilege to point out repeatedly and cumulatively the industrial and
community benefits that result from habits of health, and the
industrial and community losses that r
