Flint Implements of Upper Palæolithic Age from Yorkshire

Abstract

IN answer to Mr. Burchell, it is inaccurate to say that I relegated Lamplugh's “Late Glacial Boulder Clay” deposit to Late Pleistocene times, since Lamplugh nowhere described the flint-bearing deposit by those words. In his paper on the Drifts of Flamborough Head (Quart. Jour. Geol. Soc., vol. 47, pp. 384–431; 1891) he shows the deposit in question in only one of his fifteen sections, that at Danes' Dyke; he describes it as “a few feet of loamy stuff resembling a weathered Boulder Clay” and as “stony earth like weathered Boulder Clay”, and in a generalised table includes it under the heading “Late Glacial Gravels, Brickearth, and Boulder Clay”. In all other sections Lamplugh ignores this deposit; he also omits to show any soil or subsoil. I personally am convinced that if Lamplugh were with us to-day he would class Mr. Burchell's deposit under some such heading, or use the more expressive Yorkshire term, ‘muck’. In the memoir on Holderness, Clement Reid definitely classes the bed at Kelsey Hill, Burstwick, as Post-Glacial.
