When we remember that the careful investigations of the various dispensaries for the treatment of tuberculosis in our larger cities, New York, Boston, Cleveland, report that on an average twenty to thirty per cent of all children living in the same room or apartment with a consumptive member of their family are found to show some form of tuberculosis, it will be seen how well worth while, from every point of view, this provision for the removal and sanatorium treatment of the poorer class of these unfortunates would be. These dispensaries now have, as a most important part of their campaign against the disease, one or more visiting nurses, who, whenever a patient with tuberculosis is brought into the dispensary, visit him in his home, show him how to ventilate and light his rooms as well as may be, give practical demonstrations of the methods of preventing the spread of the disease, advise him as to his food, and see that he is supplied with adequate amounts of milk and eggs, and, finally, round up all the children of the family and any adults who are in a suspicious condition of health, and bring them to the dispensary for examination. Distressing as are these findings, reaching in some cases as high as fifty and sixty per cent of the children, they have already saved hundreds of children, and prevented hundreds of others from growing up crippled or handicapped. It must be remembered that the tubercle bacillus causes not merely disease of the lungs in children but also a large majority of the crippling diseases of the bones, joints, and spine, together with the whole group of strumous or scrofulous disorders, and a large group of intestinal diseases and of brain lesions, resulting in convulsions, paralysis, hydrocephalus, and death. The battle-ground of the future against tuberculosis is the home. We speak of the churchyard as "haunted," and we recoil in horror from the leper-house or the cholera-camp. Yet the deadliest known hotbed of horrors, the spawning ground of more deaths than cholera, smallpox, yellow fever, and the bubonic plague combined, is the dirty floor of the dark, unventilated living-room, whether in city tenement or village cottage, where children crawl and their elders spit.
