for their resourcefulness, skill, and fidelity in carrying out much of the field research. Carol Cronk and Karen Edgington gathered systematic information which was helpful in our analysis of the children's groups. Hilton Hedrick, the community organizer, made our task much easier through his generous cooperation in introducing us to people in the area and by allowing us free access to agency records. Special thanks are due our colleagues Wendell Bell and Charles R.
