In an arid district like Breckland, the vicinity of the meres, which provided a water-supply, fish, fowl and molluscs, remote from river-valleys, was eminently suitable for settlements of prehistoric man. Pile-dwellings have been found in two of the Wretham Park meres, and there are evidences of settlements on a small plateau on the east shore of Fowlmere, a similar plateau on the north-east bank of Langmere, and the north and south shores of Ringmere. The bed of Langmere confirms the evidence of an important settlement. The southern portion contains quantities of pot-boilers and a bank projecting into the mere from the south-west corner of the island seems to be chiefly made of pot-boilers. Many flakes, of types and patinas similar to those recorded hereafter, are also found in the bed of Langmere, and on its shores. Flakes and pot-boilers have also been found near most of the other meres, and Dr. Marr has described (Proc. Vol. I., p. 374) “A Late Palæolithic Site on Wretham Heath,” east of Langmere.
