“3. The _relative importance_ to be assigned to the different aims and means of physical education mentioned varies, of course, with the age, sex, environment, and other conditions of life and work. The teaching of hygiene and the health habits emphasized must be related to the grade of intelligence and the special needs and interests of the individual at each stage, from early childhood to full maturity. The activities of the _kindergarten_ and the _lower school grades_ should be directed chiefly toward promotion of normal growth and organic development, by exercise of the fundamental muscle groups, and particularly through the agency of simple games, which also furnish a valuable social training at this period. In the _upper grades_ and the _high school_ training in coördination, with suitable attention to posture, should become a prominent feature. Too often, nowadays, the _college or university_ department of physical education is called upon to adopt measures which would be quite unnecessary with an adequate system in the elementary and secondary schools, and to remedy conditions of malgrowth and maldevelopment which ought never to have been allowed to develop. After the high school period conservation of health and the higher social values would normally become the dominant objectives. Outside the limits of school life, _i.e._, in dealing with _industrial or professional groups_, conditions of occupation and environment must determine the aim and content of whatever plan is adopted. “RELATIONS. 1. Closely associated with the purposes of physical education are _other procedures_ which any complete health program in a school, college, university, or system of schools will include. These are measures intended to secure (1) prompt _detection of illness_ and physical defects, through preliminary and periodic medical inspection and physical examinations, and (2) _adequate treatment_, by means of hospital, dispensary, or private service; and (3) to provide _sanitary safeguards_, such as attention to food and water supplies, sewage disposal, light and ventilation, rooming conditions, and the early recognition and isolation of cases of communicable disease. Such measures call for the employment of a practising physician and health officer, whose services might also be utilized in the examinations given by the department of physical education and in the instruction in personal hygiene and public sanitation. For all other purposes mentioned in this report the oversight of a specially trained educator is required. “2. The influence of a well-organized department of physical education ought to be felt in every phase of school work, through _coöperation_ in attempts to promote mental hygiene and to follow hygienic principles in the choice of methods of instruction and management. Teachers in other departments may be stimulated and helped to maintain themselves in a condition which renders their own work more effective.” BIBLIOGRAPHY.
