After an outline of the continental background of the British neolithic cultures the book contains two subdivisions. Professor Piggott first describes those cultures that he classes as primary: that is those bought to Britain by colonists who bought a knowledge of agriculture. He then shows how there arose derivative secondary neolithic cultures showing a resurgence of earlier characteristics. Finally all the British neolithic cultures are considered in relation to one another and to their continental setting, and an outline of relative and absolute chronology is made.
