A cold can always be charged to some one else. How many can be laid to our account? There is one right that is universally not recognized, and that is the right of protection from the germs showered in the air we breathe, over the food we eat, by the sneezes of our unfortunate neighbor at school, in the street car, at the restaurant. The chief danger of a cold is to our neighbor, not to ourselves. A cold which a strong person may throw off in a day or two may mean death to his tuberculous neighbor. Though for our own health "lying up for a mere cold" is an unnecessary bore, the failure to do so may deprive our neighbor of a right greater than the right to protection against scarlet fever or smallpox. Though formerly this statement would not have been true, rights change with conditions, and the fact that to-day the three most deadly diseases are pneumonia, tuberculosis, and diphtheria,—all diseases of the respiratory organs,—justifies the assertion that we have a right to protection against colds. The prevalence of colds, sore throats, irritated vocal cords, bad voices, catarrh, bronchitis, laryngitis, and asthma in America to-day demands summary measures. One can learn to sneeze into a handkerchief, not into a companion's face or into a room. School children can be taught to avoid handkerchiefs on which mucus has dried. In the far distant future we may be willing to use cheesecloth, and boil it or throw it away, or, like the Japanese, use soft paper handkerchiefs and burn them after using.

One child with a cold can infect a whole class or family, thus depriving the class and family of the top of their vitality and efficiency without their consent. Because a person is thought a weakling who lies up for a "mere cold," one is inclined to wish that colds were as prostrating as typhoid, in which case there would be some hope of their extermination.

The exclusion of children with colds from school deserves trial as a check to children's diseases. Many of these "catching" diseases start with a cold in the head, as, for instance, measles, influenza, and whooping cough. The first symptom of mumps, diphtheria, and scarlet fever is a sore throat or swollen glands, which, because they commonly accompany a cold, are not at first distinguished from it.

The first step for the teacher or mother in reading the index for colds is to look into the coat closet for evidence of warm clothing and overshoes, then to note whether the children put them on when they go out for lunch or recess. Whether "cold" settles in the nasal passages, ear, or stomach depends upon which is the weak spot. Draughts, thin soles, wet soles, exposure when perspiring, may be the immediate cause of the nutritional or respiratory disturbances that give cold germs a foothold. Adenoids, diseased teeth, inflamed ears, may furnish the food supply. "There is no use treating children and sending them on fresh-air trips as long as they have nutritional and digestive disturbances due to bad teeth, or colds due to adenoids," said a physician when examining a party of children for a summer outing. The great preventive measure to be taken for catching diseases, colds, diseased glands,—in fact all germ diseases,—is the repeated cleansing of those portions of the human body in which germs may find lodgment,—the mouth, the nose, the eyes, and the ears.

In caring for young infants great pains is taken to cleanse all the orifices daily, but as soon as the child washes himself this practice is usually abandoned. Washing these gateways is far more important than washing the surface of the body through which germs could not possibly gain entrance into the system except through wounds. Oftentimes the douching of the nostrils with salt water will stop a cold at once. The mouth is the most important place of all, and the teacher should take care of her pupils' mouths first and foremost. As bad teeth, enlarged tonsils, and adenoids harbor germs and putrescent matter that vitiate every incoming and outgoing breath, these defects should be immediately corrected. Are we coming to a time when a thorough house-cleaning in the mouth of every child will take place before he enters the schoolroom, preferably in the presence of the teacher?

Two other "catching" diseases cause city schools a great deal of trouble,—trachoma and pediculosis (head lice). There are probably no two diseases more quickly transmitted from one person to another. Almost before their presence is known, all children of a school or all persons of a group have contracted them. When at college twenty men of my fraternity discovered almost at the same time that they had an infectious eye trouble; yet we thought we were using different towels and otherwise taking sanitary precautions. Last summer a Vassar graduate took a party of tenement children for a country picnic. She returned with head lice that required constant attention for weeks. What then may we expect of children who live in homes where there is neither water, time, nor privacy for bathing, where one towel must serve a family of six, where mothers work for wages away from home and see their children only before seven and after six?

Unfortunately for thousands of children, many parents still believe these troubles will be outgrown. Last summer a fresh-air agency in New York City arranged for several hundred school girls to go to a certain camp for ten days each. The only condition was that the heads should be free from lice and nits (eggs). From the list furnished by school-teachers—girls supposed to have been cured by school nurses—not one in five was accepted. A baby two weeks old, brought to Caroline Rest, had already begun to suffer from this easily preventable scourge. Of 1219 children examined in Edinburgh, Scotland, 909, or 69 per cent, had some skin disease, and 60 per cent had sores due to head lice. Even when neglect has caused the loss of hair and ugly sores on the head, mothers deceive themselves into believing that some other cause is responsible.

Trachoma, if neglected, not only impairs the health of the eye, but may cause blindness. Tears carry the germs from the eye to the face, where they are taken up on handkerchiefs, towels, and fingers and infect other eyes. Of late, thanks to school nurses and physicians and hygiene instruction, American cities have found relatively little trachoma except among recent immigrants. So dangerous is the germ and so insidious its methods of propagation, that a physician should be summoned at once at the first sign of inflammation. Conjunctivitis is due to a germ, and will spread unless checked. Since the board of health of New York City has instituted the systematic examination of the eyes of the children in the public schools, it has found fully one third affected with some form of conjunctivitis. Many of these cases are out-and-out trachoma, others acute conjunctivitis, and a larger proportion are "mild trachoma." This last form of the disease is found to a great extent among children who have adenoids. The adenoids should be regarded as a predisposing factor rather than a direct cause. Therefore sore eyes are given as one of the indexes of adenoids. When we consider that adenoids are made up of lymphoid material, and that trachoma follicles are made up of the same sort of tissue, it is not surprising that the two conditions are found in the same child. The catarrhal inflammation produced by adenoids in the nasal mucous membrane travels up the lachrymal duct and thus infects the conjunctiva by contiguity.

In preventing pediculosis and infection of the eye vigilance and cleanliness are indispensable. After the diseases are advanced, after the germ colonies have taken title, some antiseptic or germ killer more violent than water is needed,—kerosene for the hair or strong green oil soap; for the eye, only what a physician prescribes.
