The aim of the Prehistoric Society in undertaking excavations was to uncover systematically a complete settlement and to discover as much as possible about it as a social and economic organism. Little Woodbury had much to recommend it. The existence of a good air-photograph meant that no efforts need be wasted on unproductive work, besides promising interesting results for the interpretation of air-photographs. Being typical of a whole group, its elucidation might be expected to throw light upon a number of similar sites. Further, experience has shown that incontestable results are to be won most readily where the habitation is not too dense and where occupation has been confined to one period. The air-photograph seemed to promise the former, while the test excavations carried out by Mr C. W. Phillips, F.S.A., in March 1938, suggested that the settlement was substantially of the Iron Age A culture.
