NEOLITHIC SITES IN UPPER VALLEY OF ESSEX CAM. 61 carbonate and the aretes are very sharp and unweathered. The assemblage of flakes and cores bears a strong resemblance to the debris of a working floor at Grimes Graves and is in striking contrast to other worked flints in the Walden area. This site, when first discovered, was of great interest. Three large battered flints (anvil stones) were exposed by a wash-out of the over-lying soil and formed a rough table, surrounding which were quantities of spales and cores. These were lying on the gravel and were exposed in layers of sharp edges in the overlying bank. Subsequently the turf and loam of the bank was removed and a trench dug into the gravel. It was found that the worked flint was limited to a circle about ten feet in diameter and did not extend into the gravel. Many of the flakes and cores had small portions of the original crust, which showed water erosion. The type of flaking is very distinct from that on other areas in this district and may indicate a different stratum of culture. The position of the site in relation to the present water level is significant as indicating the small amount of valley erosion that has taken place since Neolithic times. V. Littlebury. Bordeaux Site. Essex. Sheet II. S.E. Longitude 0° 12' 2" E., latitude 52° 2' 58" N. Elevation between 130 and 180 feet O.D., and about 6ft. above water level at the nearest point to the river. The site is extensive and lies upon the fields between the London and Cambridge main road and the G.E. Railway from the Bordeaux farms to Littlebury village. It lies upon a gravel terrace of the Barn- wellian Series (10), the general structure of which is described in the Geological Survey Memoir (12). The gravel is covered with a sandy decalcified loam which in places reaches a depth of more than five feet. The soil is decalcified, brown and very sandy. The artifacts are small and a variety of flakes, cores, scrapers, points and other implements are found. The bulk of the worked flint is unpatinated and has a greyish, lustrous appearance, which is highly characteristic of flint from sandy sites in this area. The remainder is mainly of the blue mottled type of patination. A finely worked circular scraper was taken from a depth of 2ft. 6in. in the loam. The general character of the worked flint from this site has a
