In July last I discovered two “floors” or occupation-levels in North-West Suffolk, one of Neolithic age on Foxhole Heath, Eriswell, and the other of Early Iron age on Barnham Common, Thetford. The former was on the N.W. slope of a dry valley, about a mile in length, connected with a tongue of the fenland, and just below the 50 ft. contour. The thin layer of black earth which marked the land surface on which the Neolithic people lived and made their implements was covered by two or three feet of sand, almost stoneless and apparently wind-drifted. Some of this had been washed away, leaving a dark surface on which were potboilers, pottery, numerous cores, flakes and chips, and about thirty flint implements. The potsherds were kindly examined by Mr. A. G. Wright, who reported that it was difficult to date them, as that kind of ware lasted from Bronze Age to late Roman times. A small piece of red ware, with square or rectangular notch ornament, was evidently part of a beaker of Late Neolithic or Early Bronze Age. Beakers are usually found with inhumation burials, and are the earliest of the sepulchral types in this country.
