125 "PRIMAEVAL MAN IN THE VALLEY OF THE LEA." (Conclusion.) By WORTHINGTON G. SMITH, F.L.S., M.A.I , etc. Implements. Nearly all the Palaeolithic Implements found in England are made of flint: in the cherty gravels of Dorset, Somerset, and Devon they are, however, made of chert. On very rare occasions a Thames Valley implement is made of quartzite. I have seen a few flakes of quartzite in the Stoke Newington gravels, but as far as I know only one implement of this intractable material has been met with there. This was formerly No. 1,317 in my collection, and is now in the British Fig. 1.—Paleolithic Implement of compact quartzite from Creighton Road, Stoke Newington (one-half actual size). Museum, Bloomsbury ; it is a very good example, weighs 13 ozs., is made of compact quartzite, and is illustrated one-half its actual size fig. 1. Why Palaeolithic men now and then made quartzite imple- ments in positions where flint was abundant, is hard to say, they were possibly made for amusement, or as proofs of unusual skill and dexterity, they were certainly not made from necessity, for their manufacture was very much more difficult than in the ordinary tools of flint.
