If you saw "Public Health" at the head of a chapter, you might not think it looked very interesting; but when you once get the idea that if your mother had had her say on the Public Health Board you would have had a fine skating pond with a good skate-house, last winter, and sunny, well-aired school rooms to study in, with a big gymnasium for basket ball in bad weather, you may be more interested in the merit badge for Public Health called "Health Guardian!" Remember that Public Health is simply good housekeeping, applied to the community. It is a subject which women are sure to take up more and more, and a Girl Scout who has given the matter a little thought and study is going to make a good citizen later on, and will be certain to have her advice asked--and taken--in the matter of making her town healthy and happy. For instance, if the desks in the public schools are not of the right height and shape, the children are bound to suffer in their health and hygiene. It is the business of the State to see that all public buildings, schools, theatres, factories, etc., have a certain amount of light and air to the cubic foot, because so much is necessary for health. It is the business of the State to see that only a certain number of hours a day should constitute a day's work. This is because a certain amount of rest is a necessity for all citizens. It is the business of the State to see that food and water can be brought into the community. Also that they be kept pure, both in transportation and after they reach the community. This includes the policing of all reservoirs and the filtering of the water; the refrigerating of meat and milk; the condemning of rotten fruit and vegetables; the collecting and disposal of all garbage and waste. It is the business of the state to prevent spitting in public places, (one of the greatest sources of public infection); to prevent the use of common drinking utensils, towels, etc.; to insist on the isolation of contagious diseases and the placarding of the houses where they occur. In order to carry on these great wise policies the state should offer free clinics where citizens can find out what is the matter with them and how to prevent it, and trained community nurses for the sick. Do you see what a wonderful power an intelligent woman can be in the community she lives in? Women ought to be much better, really, in this public housekeeping than men, because most of them have had to learn to do it on a small scale, and know how necessary light, air, rest, exercise and cleanliness are. But, you may say, as yet, I am too young to vote, anyway; what can I do? The answer is very simple: every citizen, whether she is young or old, whether she has a vote or not, can find out the laws of the town she lives in and help to enforce them!
