Taxing is swift to follow teaching in matters of health. Teachers can easily compute what their community loses from tuberculosis. The totals will for some time prove a convincing argument for cleanliness of air, of body, and of building wherever the community is responsible for air, building, and body. The annual cost of tuberculosis to New York City is estimated at $23,000,000 and to the United States at $330,000,000. The cost of exterminating it will be but a drop in the bucket if school-teachers do their part this next generation with the twenty million children whose day environment they control for three fourths of the year, and whose habits they can determine. The first meeting in America of the International Congress on Tuberculosis was held at Washington, D.C., September 21 to October 12, 1908. For many years the proceedings of this congress will undoubtedly be the chief reference book on the conquest of tuberculosis.[14] How many aspects there are to this problem, and how many kinds of people may be enlisted, may be seen from the seven section names: I. Pathology and Bacteriology; II. Sanatoriums, Hospitals, and Dispensaries; III. Surgery and Orthopedics; IV. Tuberculosis in Children--Etiology, Prevention, and Treatment; V. Hygienic, Social, Industrial, and Economic Aspects; VI. State and Municipal Control of Tuberculosis; VII. Tuberculosis in Animals and Its Relation to Man. [Illustration: FIGHTING TUBERCULOSIS IN CHEAP SHACKS, $125 PER BED, OTISVILLE, NEW YORK] How many-sided is the responsibility of each of us for stamping out tuberculosis is shown by the preliminary programme of the eight sessions of Section V. These topics suggest an interesting and instructive year's study for clubs of women, mothers, or teachers, or for advanced pupils. I. ECONOMIC ASPECTS OF TUBERCULOSIS 1. The burdens entailed by tuberculosis: a. On individuals and families. b. On the medical profession. c. On industry. d. On relief agencies. e. On the community. f. On social progress. 2. The cost of securing effective control of tuberculosis: a. In large cities. b. In smaller towns. c. In rural communities. II. ADVERSE INDUSTRIAL CONDITIONS 1. Incidence of tuberculosis according to occupation. 2. Overwork and nervous strain as factors in tuberculosis. 3. Effect of improvements in factory conditions on the health of employees. 4. Legitimate exercise of police power in protecting the life and health of employees. III. THE SOCIAL CONTROL OF TUBERCULOSIS 1. Outline of a comprehensive programme for: a. National, state, and municipal governments. b. Departments of health and departments of public relief. c. Private endowments. d. Voluntary associations for educational propaganda. e. Institutions, such as schools and relief agencies, which exist primarily for other purposes.
