As was pointed out in the chapter on definitions, each of these various groups has a customary center for coming together. But owing to the fact that each interest has grown largely without reference to the others, their centers of activity have been determined largely by conditions of local convenience. Now, these centers may have been well adapted to the times when they were established, but as time has passed shifts of population have come, road improvements have been made, and new interests developed so that the traditional centers not only tend to lessen community solidarity but also tend to prevent its accomplishment. One of the first tasks of the community leader is to make a study of his proposed field of activity for the purpose of determining what are the present centers of group interests, what changes have taken place in rural life conditions which make reorganization and readjustment of centers desirable, and then, in consultation with representatives of the community, to organize a community plan toward ward which the entire community may work. City planning has long been an accepted principle for service in the more progressive larger centers. The time has come when plans for the most efficient organization of village and open country communities should be made. It is interesting to note that already in many sections of the United States the movement toward community planning has made considerable progress. It is now generally recognized that with rare exceptions the village rather than an open country point is the normal basis for such a plan. In accordance with this, movements are now under way to displace the traditional township boundaries created as political limits for government and to replace them by boundaries conforming as closely as possible with those limits that careful investigation indicates are now and probably will continue to be the most representative of what the future limits of rural communities will be. In like manner educational work is being reorganized to include the community territory instead of the political areas inherited from the methods of survey adopted under the ordinance of 1787. As this movement continues, doubtless farm bureaus, and even religious agencies, will try to adapt themselves as far as possible to the program of other agencies.
