The need, therefore, is for the education of rural people with regard to their social responsibilities, which must be largely accomplished through existing local rural organizations and local leadership. Any system of rural social work which is to be permanently successful must be one which is established by the people themselves from a realization of their needs, and progressively developed as they appreciate its worth. As Dean A. R. Mann recently said, "In dealing with rural affairs it has long been a common mistake to underrate the validity of the farmer's own judgment as to what is good for him." "Superimposed organizations are usually doomed to failure because they express the judgments of those without the community rather than those within whom they are intended to serve." "Ordinarily the most serviceable rural organizations will be built out of the materials of the community."[74] It is for this reason that the advance of rural social work will depend upon arousing an active interest in the welfare of the community's "disadvantaged" through discussion by such organizations as the church, the grange, the farm and home bureau, lodges, women's clubs, instruction in high schools, etc. The work of the public health nurse will reveal many family problems with which she is unable to deal and which demand the help of one experienced in social work, and the nurse will be of service in educating the community to the need of such work. It seems obvious that by itself the rural community is too small a unit to employ a social worker who is professionally trained for dealing with the more difficult social mal-adjustments, and that it must cooperate with other communities for the organization of such work on a county basis. Experience has shown that trained social workers actually save the county the cost of their salaries and expenses, without considering the greater efficiency and permanent value of the work done. The social worker has been well termed a "doctor of domestic difficulties." Every county and community needs such a doctor who is skilled in treating social disease, but one of her chief functions will be to act as an educational director in promoting the study of local social conditions by the existing organizations in every community and in discovering and training leadership for carrying out a constructive program as it is evolved. In some way there should be a volunteer committee or worker in each community associated with the county social worker to advise concerning policies and to carry on much of the local work under her supervision and training. For it must be recognized that the economic resources of rural communities are limited and that they cannot afford several social workers for different lines of effort, as is common in cities. But more important is the fact that social welfare depends more largely upon a proper understanding of its problems by the local community and a willingness to grapple with them intelligently and
