The book investigates the effects on huter-gatherers of a hypothesised frontier with agriculturalists in the Caledon Valley. The frontier hypothesis was based on previous Iron Age research, whereas tha presence of hunter-gatherers was noted from historical sources. The study examines the social aspect of mixing huter-gatherers and agriculturalists, by focusing on the mechanisms involved in long-standng co-operative relationships. Exchange relationships and clientship are explored.
