A recently desegregated high school student subsystem in a Deep South urban center is examined in this paper. It was found that although court ordered desegregation paired two high school populations, it did not effect racial boundaries. The whites, largely because they had been attending the school prior to desegregation, have been able to maintain their control over many student activities. As the blacks have taken over areas such as sports and cheerleading, the status of these has been refuted by whites. In areas such as student government, clubs, ROTC and the yearbook, the whites have been able to control these organizations and most of the activities sponsored by them. This control, for the most part, has come through the rigid maintenance of the boundaries separating blacks and whites. Students crossing these boundaries have been sanctioned by their own groups. These findings are analyzed by a model for desegregation similar to that of Barth's, where ethnic groups attempt to manipulate rewards and resources and yet protect boundaries. (Author/GC)
