For many reasons it is perhaps unfortunate that we can breathe at all when the nose is stopped up. If we could see with our ears as well as with our eyes, we should probably not take as good care of our eyes. In this respect the whole race has experienced the misfortune of the man of whom the coroner reported, "Killed by falling too short a distance." Because we can breathe through the mouth we have neglected for centuries the nasal passages. When a cold stops the nose we necessarily breathe through the mouth. Unfortunately children make the necessary effort required to breathe through the nose long before other people notice the lines along the nose and the slow mind. Mouth breathing will show with the child asleep, before the child awake loses power to accommodate his effort to the task. Therefore the importance of a physical test at school to detect the beginnings of adenoids and large tonsils before these symptoms become obvious to others.
No child should be exempted from this examination because of apocryphal theories that only the poor, the slum child, the refractory, or the unclean have defects in breathing. This very afternoon a friend has told me of her year abroad with a girl of nine, whose parents are very wealthy. The girl is anæmic. Her backwardness humiliates her parents, especially because she gave great promise until two years ago. High-priced physicians have prescribed for her. It happens that they are too eminent to give attention to such simple troubles as adenoids that can be felt and seen. They are looking for complications of the liver or inflammation of muscles at the base of the brain. One celebrated French savant found the adenoids, assured the mother that the child would outgrow them, and advised merely that she be compelled to breathe through the nose. The mother and nursemaids nag the child all day. The poor unwise mother sits up nights to hold the child's jaws tight in the hope that air coming through the nose will absorb the adenoids. The mother is made nervous. Of course this makes the child more nervous and adds to the evil effects of adenoids. If the mother had the good fortune to be very poor, she could not sit up nights, and would long ago have decided either to let the child alone or else to have the trouble removed.
