_Health._--The girl scout learns that "a cheerful scout, a clean scout, a helpful scout is a well scout. She is the only scout that really _is prepared_." So that health, physical and mental, is the keynote to the scout activities, which are calculated to develop the habit of health, rather than simply to give information about anatomy or physiology. Personal health is recognized by the badge of "Health Winner," given to the girl who for three months follows certain rules of living, such as eating only wholesome food, drinking plenty of water, going to bed early, exercising in the open air, and keeping clean, and who shows the result by improved posture, and by the absence of constipation and colds. Outdoor sports, swimming, boating, and dancing are other health-producing activities. Of all health-promoting activities, camping is the best, and this means all stages of life in the open, from the day's hike, with one meal out of doors, to the overnight or week-end hike, and finally the real, big camp, open all summer. Girl scouts learn how to dress for outdoor living, how to walk without fatigue, and how to provide themselves with food, warmth, and shelter, so that "roughing it" does not mean being uncomfortable. During 1920, 50 large girl-scout camps were maintained in 16 States. These are self-supporting, and as they are open for 10 weeks as a rule and accommodate about 50 girls at a time, they give an opportunity to several thousand for the best sort of holiday. The idea is to have enough camps to give every scout the experience. To promote this work national headquarters maintains a camping section and has published a book, "Campward Ho!" which gives full directions for organizing and running large, self-supporting camps for girls. Community health habits are quite as important as the purely personal, and the older girl scout is expected to become a "health guardian," which means that she takes an intelligent interest in the things pertaining to public health, such as playgrounds, swimming pools, school lunches, the water and milk supplies, clean streets, the disposition of waste and garbage, the registration of births, and the prevention of infant mortality. She also learns how to help in times of emergency as first aid, in sickness as home nurse, and at any time as child nurse. A scout whose mind is filled with interesting facts about birds and animals and trees, and who is busy playing games with her companions or in making useful and beautiful things and in rendering active service to her home and community, is apt to have a healthy mind without thinking much about it. And she has a little rule for the blue times, which is "to smile and sing under all difficulties."
