of society into the categories of savagery, barbarism, and civilisation, although added the innovation of dividing savagery into higher and lower forms. Fagan later noted that in adopting Tylor's tripartite division, the book was "old-fashioned even for the 1940s". During the summer break of 1947, Clark led a team of undergraduates in the excavation of Bullock's Haste along the Car Dyke near Cottenham, revealing evidence of early Romano-British activity. In 1947 and in 1948, he was awarded a Leverhulme Fellowship which allowed him to travel across much of Northern and Central Europe. He looked at the technologies and techniques of rural and fishing communities in much of Scandinavia, displaying his interest in the relationship between folk culture and ecology. He expanded the length of the Proceedings in the years following the war, now aided by Piggott and Kenneth Oakley as his editorial assistants. In 1946, Childe resigned as the Abercromby Professor of Archaeology at the University of Edinburgh. Clark applied to succeed him, although the position was instead given to Piggott. Piggott then invited Clark to give the Munro Lectures at Edinburgh in 1949. In 1950, he was elected to a fellowship at Peterhouse, a position that he held for the next 45 years. At the college he befriended his colleague Michael Postan, an economic historian whose research into Medieval farming techniques inspired Clark to reassess Neolithic farming. In 1951, he contributed a chapter on the use of folklore in interpreting prehistory for a festschrift devoted to Childe. Fagan later described this chapter as one of Clark's most important papers. Using his Munro Lectures as a basis, Clark also wrote a book, Prehistoric Europe: the Economic Basis, which reflected his interest in ecology and the impact that it had on the economics of human society. The book received mixed reviews, although would be described by Fagan as "arguably the most influential of all Clark's books". It sold widely and was translated into several languages. Clark had been very impressed with Gerhard Bersu's excavation of the Iron Age settlement of Little Woodbury in Wiltshire in 1938 and 1939. After the war, he decided to excavate an Iron Age settlement nearer to Cambridge using the same techniques as Bersu had used. An amateur archaeologist had found early Iron Age pottery on Micklemoor Hill near West Harling in Norfolk, and Clark began an excavation of the site in 1948. However, before Clark could
