Last winter the chairman of the Committee on the Physical Welfare of School Children was invited to speak of physical examination before an association of high-school principals. He began by saying, "This question does not concern you as directly as it does the grammar-school principals, but you can help secure funds to help their pupils." One after another the high-school principals present told--one of his own daughter, another of his honor girls, a third of his honor boys--the same story of neglected headaches due to eye strain, breakdowns due to undiscovered underfeeding, underexercise, or overwork. Are we coming to the time when the state will step in to prevent any boy or girl in high school, college, or professional school from earning academic honors at the expense of health? Harmful conditions within schoolrooms and on school grounds will not be neglected where pupils, teachers, school and family physicians, and parents set about to find and to remove the causes of physical defects. Disease centers outside of school buildings quickly register themselves in the schoolroom and in the person of a child who is paying the penalty for living in contact with a disease center. If a child sleeps in a dark, ill-ventilated, crowded room, the result will show in his eyes and complexion; if he has too little to eat or the wrong thing to eat, he will be underweight and undersized; if his nutrition is inadequate and his food improper, he is apt to have eye trouble, adenoids, and enlarged tonsils. He may have defective lung capacity, due to improper breathing, too little exercise in the fresh air, too little food. Existence of physical defects throws little light on income at home, but conclusively shows lack of attention or of understanding. Several days' absence of a child from school leads, in every well-regulated school, to a visit to the child's home or to a letter or card asking that the absence be explained. Even newly arrived immigrants have learned the necessity and the advantage of writing the teacher an "excuse" when their children are absent. Furthermore, neighbors' children are apt to learn by friendly inquiry what the teacher may not have learned by official inquiry, why their playmate is no longer on the street or at the school desk. While physicians are sometimes willing to violate the law that compels notification of infection, rarely would a physician fail to caution an infected family against an indiscriminate mingling with neighbors. Whether the family physician is careless or not, the explanation of the absence which is demanded by the school would give also announcement of any danger that might exist in the home where the child is ill.
