questions as to their own living conditions until told that the answers would make it easier to get better health environment not only for their own children but for their neighbors' children. Generally speaking, fathers and mothers can easily be interested in any kind of campaign in the name of health and in behalf of children. The advantage of starting this health crusade from the most popular American institution, the public school,— the advantage of instituting corrective work through democratic machinery such as the public school,— is incalculable. To any teacher, pastor, civic leader, health official, or taxpayer wanting to take the necessary steps for the removal of conditions prejudicial to health and for the enforcement of health rights of child and adult, the best possible advice is to learn the facts disclosed by the physical examination of your school children. See that those facts are used first for the benefit of the children themselves, secondly for the benefit of the community as a whole. If your school has not yet introduced the thorough physical examination of school children, take steps at once to secure such examination. If necessary, volunteer to test the eyes and the breathing of one class, persuade one or two physicians to coöperate until you have proved to parent, taxpayer, health official, and teacher that such an examination is both a moneysaving, energy-saving step and an act of justice. We shall have occasion to emphasize over and over again the fact that it is the use of information and not the gathering of information that improves the health. The United States Weather Bureau saves millions of dollars annually, not because flags are raised and bulletins issued foretelling the weather, but because shipowners, sailors, farmers, and fruit growers obey the warnings. Mere examination of school children does little good. The child does not breathe better or see better because the school physician fills out a card stating that there is something wrong with his eyes, nose, and tonsils. The examination tells where the need is, what children should have special attention, what parents need to be warned as to the condition of the child, what home conditions need to be corrected. If the facts are not used, that is an argument not against obtaining facts but against disregarding them. In understanding medical examination we should keep clearly in mind the distinction between medical school inspection, medical school examination, and medical treatment at school. Medical inspection is the search for communicable disease. The results of medical inspection, therefore, furnish an index to the presence of communicable diseases in the community. Medical examination is the search for physical defects, some of which furnish the soil for contagion. Its results are an index not only to contagion but to conditions that favor contagion by producing or aggravating physical defects and by reducing vitality. Medical treatment at school refers to steps taken under the school roof, or by school funds, to remove the defects or check the infection brought to light by medical inspection and medical examination. Treatment is not an index. In separate chapters are given the reasons for and against trying to treat at school, symptoms of causes that exist outside of school. When, how often, and by whom inspection and examination should be made is also discussed later. The one point of this chapter is this: if we really want to know where in our community health rights are endangered, the shortest cut to the largest number of dangers is the physical examination of children at school,— private, parochial, reformatory, public, high, college. Apart from the advantage to the community of locating its health problems, physical examination is due every child. No matter where his schooling or at whose expense, every child has the right to advance as fast as his own powers will permit without hindrance from his own or his playmates' removable defects. He has the right to learn that simplified breathing is more necessary than simplified spelling, that nose plus adenoids makes backwardness, that a decayed tooth multiplied by ten gives malnutrition, and that hypertrophied tonsils are even more menacing than hypertrophied playfulness. He has the right to learn that his own mother in his own home, with the aid of his own family physician, can remove his physical defects so that it will be unnecessary for outsiders to give him a palliative free lunch at school, thus neglecting the cause of his defects and those of fellow-pupils. PART II. READING THE INDEX TO HEALTH RIGHTS CHAPTER V MOUTH BREATHING If the physical condition of school children is our best index to community health, who is to read the index? Unless the story is told in a language that does not require a secret code or cipher, unless some one besides the physician can read it, we shall be a very long time learning the health needs of even our largest cities, and until doomsday learning the health needs of small towns and rural districts. Fortunately the more important signs can be easily read by the average parent or teacher. Fortunately, too, it is easy to persuade mothers and teachers that they can lighten their own labors, add to their efficiency, and help their children by being on the watch for mouth breathing, for strained, crossed, or inflamed eyes, for decaying teeth, for nervousness and sluggishness. Years ago, when I taught school in a Minnesota village, I had never heard of adenoids, hypertrophied tonsils, myopia, hypermetropia, or the relation of these defects and of neglected teeth to malnutrition, truancy, sickness, and dullness. I now see how I could have saved myself several failures, the taxpayers a great deal of money, the parents a great deal of disappointment, and many children a life of inefficiency, had I known what it is easy for all teachers and parents to learn to-day. The features in the following cut are familiar to teachers the world over. Parents may reconcile themselves to such lips, eyes, and mouths, but seldom do even neglectful parents fail to notice "mouth breathing." Children afflicted by such features suffer torment from playfellows whose scornful epithets are echoed by the looking-glass. No fashion plate ever portrays such faces. No athlete, thinker, or hero looks out from printed page with such clouded, listless eyes. The more wonder, therefore, that the meaning of these outward signs has not been appreciated and their causes removed; conclusive reason, also, for not being misled by recent talk of mouth breathing, adenoids, and enlarged tonsils, into the belief that the race is physically deteriorating. Three generations ago Charles Dickens in his Uncommercial Traveller pointed out a relation between open mouths and backwardness and delinquency that would have saved millions of dollars and millions of life failures had the civilized world listened. He was speaking of delinquent girls from seventeen to twenty years old in Wapping Workhouse: "I have never |
