Some of the Plateau implements were found not on the surface but
In a footnote to the above passage, Prestwich (1892, p. 251) went on to say: “Mr. Bullen has just had a trench dug on the top of Preston Hill. It was nearly five feet deep, through surface soil (one foot); and the red-clay-with-flints in which, at a depth of three feet ten inches from the surface, he found an unworn white flint—apparently the broken point of a small implement.” As we have seen, Edmunds (1954, p. 56) characterized major portions of the clay-with-flints deposits as
3.2.5 The Relative Antiquity of Eoliths and Paleoliths
Returning to the eoliths found on the surface of the Plateau, Prestwich (1892, p. 252) asked: “could these implements, like the neolithic implements which occur on the same ground, have been dropped on the surface where they are now found, at some later date?” Although most of the Neolithic implements were found in the lower river terraces, some did occur on the Plateau. Prestwich (1892, p. 252) went on to state, in response to his own question: “The answer to this is, that these neolithic implements show only weathering by exposure on the surface, and are found at all levels, whereas the plateau implements, besides their wear and colour, present all the physical characteristics due to having been
