Yet the greatest problem in infant mortality has still to be solved. This is the care of the “institution” baby. As in England and in France, the largest number of deaths among New York children occur among the illegitimate and those lacking a mother’s care during the early months of life. In 1911 more than forty per cent. of the deaths of infants under one year in Manhattan occurred in institutions. The institutions that receive foundlings are too few and too poorly equipped. One day Mr. J. Pierpont Morgan saw in the street, within a block of his home, a poor woman hugging despairingly to her breast a new-born infant. In consequence, he caused to be built the million-dollar lying-in hospital on Stuyvesant Square, which has already been the means of saving many an innocent life. But that superb hospital, large as it is, has not the facilities for taking care of more than a small number of the infants that require such an institution. The material agencies, efficient and marvelous as they have become, have not been the chief aid in the reduction of the death-rate, especially among children. Public education has really had more to do with it. Even those in direct charge of the work in infant mortality do not assert that the entire credit for the satisfactory progress should be given to the milk stations, the dispensaries, and the hospitals. Pamphlets, lectures, newspaper articles, and school-room instruction are at the base of the advance. Publicity has proved to be a greater force than milk inspection. Certain popular newspapers in New York have the power to achieve definite radical reforms in modes of living whenever they choose to prosecute a vigorous campaign. Just as the newspapers can expose corruption in any of the city’s departments, so almost as readily they can uproot or at least substantially lessen certain sanitary evils. A case in point is their campaign against the fly last summer. By means of wide-spread and vigorous news articles and editorials they succeeded in so rousing the mass of the people that the fly pest was visibly reduced. Health Department officials testify readily to this. The work of the social settlements, of the mothers’ clubs, of the neighborhood nursing associations, of the diet-kitchens, all contribute to the general education that is bringing about a condition of excellent public sanitation. This work is necessarily of slow growth. Its effect is not nearly so evident as that of vaccination, of smallpox segregation, or of typhoid diagnosis. It is not so simple as establishing proper sewers or purifying the water-supply; but it is no less important. THE STUDY OF SEX HYGIENE
