Where practicable it is well to dispense with bathing suits, even the scantiest. The warm bath tub is enfeebling and degenerative, despite the cold spray later, while the free swim in cold water is most invigorating. Happily, city officials, teachers, and sanitarians are now slowly realizing the great improvement in health and temper that comes from bathing and are establishing beach and surf, spray, floating and plunge summer baths and swimming pools; often providing instruction even in swimming in clothes, undressing in the water, treading water, and rescue work, free as well as fee days, bathing suits, and, in London, places for nude bathing after dark; establishing time and distance standards with certificates and even prizes; annexing toboggan slides, swings, etc., realizing that in both the preference of youth and in healthful and moral effects, probably nothing outranks this form of exercise. Such is its strange fascination that, according to one comprehensive census, the passion to get to the water outranks all other causes of truancy, and plays an important part in the motivation of runaways. In the immense public establishment near San Francisco, provided by private munificence, there are accommodations for all kinds of bathing in hot and cold and in various degrees of fresh and salt water, in closed spaces and in the open sea, for small children and adults, with many appliances and instructors, all in one great covered arena with seats in an amphitheater for two thousand spectators, and many adjuncts and accessories. So elsewhere the presence of visitors is now often invited and provided for. Sometimes wash-houses and public laundries are annexed. Open hours and longer evenings and seasons are being prolonged. Prominent among the favorite games of early puberty and the years just before are those that involve passive motion and falling, like swinging in its many forms, including the May-pole and single rope varieties. Mr. Lee reports that children wait late in the evening and in cold weather for a turn at a park swing. Psychologically allied to these are wheeling and skating. Places for the latter are now often provided by the fire department, which in many cities floods hundreds of empty lots. Ponds are cleared of snow and horse-plowed, perhaps by the park commission, which often provides lights and perhaps ices the walks and streets for coasting, erects shelters, and devises space economy for as many diamonds, bleachers, etc., as possible. Games of hitting, striking, and throwing balls and other objects, hockey, tennis, all the courts of which are usually crowded, golf and croquet, and sometimes fives, cricket, bowling, quoits, curling, etc., have great "thumogenic" or emotional power.
