In his able article on “The Chipping of Flint by Natural Agencies,” Mr. F. N. Haward endeavoured to prove that certain flints found in the basement-bed of the Red and Norwich Crags and supposed by some archæologists to have been chipped by man, were really the product of natural forces, evidence of the working of which he considered that he had found in the Eaton Pit, Norwich. He argued that the flints were chipped either before the deposition of the gravels above by forces moving over the surface, probably stones moved by snow or ice or by currents of water (p. 188), or during or after the deposition of the gravels above, by lateral or vertical movements in the gravels. This point of view was elaborated at considerable length and supported by an excellent series of illustrations.
