If, however, her work be limited to the patients of any one institution, association, or sect, she is no longer an asset to the community. For example, if she is employed by a certain dispensary to visit its patients only, her work is circumscribed. Her usefulness will be restricted—her service will be valuable to the physicians of such an institution, and she will collect data for their records, but her duties will be localized for the good of the dispensary, rather than for society as a whole. The same would be true if she be employed by a St. Vincent de Paul Society to care for Catholic consumptives, or by a Jewish organization to follow up Jewish patients—any arrangement through which she visits one patient in a block, but refuses the case next door, means a narrow field of service. She then becomes the nurse of an institution, or a sect, rather than a public health nurse. The object of her work is not the welfare of the community, but the welfare of certain individual patients. Incidentally, her work may benefit the community, but it falls far short of its possibilities. It must be supplemented by new agencies, with the consequent duplication and waste of effort that this always involves. Our experience in Baltimore will illustrate this point. In 1904, when tuberculosis nursing was first organized, two nurses were placed in the field. One was attached to the dispensary, of the Johns Hopkins Hospital, the other placed in charge of the Visiting Nurse Association. Between them the city was divided into halves, one nurse working in the eastern, the other in the western portion of the town. The dispensary nurse visited only patients who had been to the dispensary. The nurse of the Visiting Nurse Association visited not only dispensary cases, but _all patients reported from whatever source_. Thus, in East Baltimore, if two consumptives lived in the same tenement, one a dispensary case and the other under no supervision at all, only one of these two was visited. In West Baltimore, both patients were cared for on equal terms. At the end of a year, another nurse was added to the Visiting Nurse Association staff, but not to the dispensary. The city was then redivided, this time into thirds, and again the patients were cared for under the same conditions. The dispensary nurse served the Johns Hopkins Dispensary; the Visiting Nurses served the dispensary and the community as well. Finally, in 1910, the tuberculosis work of the Visiting Nurse Association was taken over by the city, thus creating a new municipal department, the Tuberculosis Division of the City Health Department. At that time the dispensary nurse gave up visiting in the homes of the patients, and confined herself entirely to routine dispensary duties. This left all visiting work to the Health Department nurses, who were as punctilious in making reports to the dispensary as was the dispensary nurse herself. By this arrangement, the Phipps, in common with every
