The object of the excavations described in this preliminary report was to recover evidence of:(a) the more perishable elements in the material culture of a Maglemosian community,(b) the fauna on which this community largely subsisted and(c) the vegetation which formed the ecological setting of man and beast alike.The best way of appreciating the need for such an investigation and of judging the measure of success attained in this first season is to consider how knowledge of the Maglemosian culture in Britain grew up between the two world wars. There appear to have been two main clues, namely single finds of barbed bone points, commonly, though probably wrongly, referred to in the early literature as ‘harpoons,’ and flint industries of a type associated with analogous points on Maglemosian sites in the Baltic area.
