PROFESSOR TODD'S paper is confined largely to an exposition of the activities of the Community Fund movement in sociological terms. He has made clear that we may find in the movement excellent illustrative material of the concepts of sociology. It is evident, as he shows, that we find in it a wide variety of those phenomena in whose operation the sociological student is interested. The consciousness of kind, invention, competition and conflict, diffusion of a behavior pattern, collective response, influence of prestige, bonds of social cohesion, coercion, public opinion, interaction, communication, esprit de corps, segregation, accommodation, co6peration, tolerance, compromise, group mores, attitudes, slogans, social control, are but a part of the sociological concepts which the student may find well illustrated in the Community Chest. I quite agree with Professor Todd that such a movement contains a rich source for even those pure sociologists whose purity is so marked that no unclean or unholy social improvement can be included in their purview. They may disabuse themselves of any concern for the relation of Community Chests with human welfare, and still find in the movement rich material for an understanding of human behavior. There is another sociological approach, however, to the Community Chest movement than that which finds in it illustrative material for sociological concepts or sources for the study of behavior patterns. That is, we may inquire what the sociologist as a student of human behavior has to offer the Community Chest worker that will be of value to him in more effectively accomplishing his purpose. It is this aspect of the topic that appeals most strongly to me. Social workers have, at times, I believe, had legitimate cause for complaint that the sociologist has not been of great assistance in helping to provide a scientific basis for social work. The sociologist has been free to criticise the lack of a scientific approach that is frequently observable in social work, but he has not always been equally ready to furniish the scientific data on which a more intelligent program might be built. If a clear case is to be made for the importance of including a considerable amount of sociology in the training of the social worker, it is incumbent on the sociologist to show how his data may be made available for the building of a genuinely scientific structure of social work. From the background of this point of view I wish to point out several ways in which an understanding of sociological concepts and sociological techniques may be of value for the Community Chest worker. Two aspects of the movement will be con-sidered. Probably the most outstanding sociological concept with which the Community Chest worker is confronted is that of social control.
