67 NEOLITHIC AND PALAEOLITHIC SCRAPERS, REPLACED AND REWORKED. By WORTHINGTON G. SMITH, F.L.S., M.A.I., etc. Whilst investigating the Palaeolithic remains at Stoke Newington from 1878 to 1885 I found in the surface soil a few Neolithic relics such as celts, arrow-heads, scrapers, knives, and simple flakes. Upon looking over these Neolithic stones a few weeks ago I was struck by the colouration of certain examples, and by sorting them out I was enabled to replace a Neolithic scraper on to a larger flake from which it was originally struck. Both the scraper and flake were marked by me at the time of Fig. 1.—Neolithic Scraper replaced on to a mother flake, one-half actual size. Stoke Newington Common. finding, "Stoke Newington Common, 1882" I have engraved this replaced scraper one-half the actual size in fig. 1. The scraper is shown at A, the flake on to which it fits at B. It will be seen that the superimposed flake has received the necessary secondary chipping to make it a scraper, and this minor chipping exposes part of the mother flake at B. Three miles east of Dunstable, at Leagrave, and close to the source of the Lea, is a British (afterwards Roman and Saxon) camp named "Wanlud's Bank." Near this place I have found several celts, arrow-heads, scrapers, etc., including a flake struck from Lydian stone. One of the scrapers found by me is made from a flake of very much older date than the re-trimming which makes a flake into a scraper. Both the flat and faceted sides of the original flake are covered with a milky-white film of decomposition, whilst the newer work is full grey in colour. This scraper shows the great length of the Neolithic age, as the original Neolithic flake became whitened with antiquity before the newer Neolithic man picked it up and formed it by secondary chipping into a scraper. The two thousand years Fig. 2.—Neolithic Scraper made from a flake of much greater Neolithic age, one-half actual size. Wanlud's Bank, by source of River Lea, or so since the scraper was made have proved insufficient to cause any milky film to appear on the secondary chipping. How much older, therefore, must the original
