MR. W. G. CLARKE ON NORFOLK FLINT IMPLEMENTS. 219 
All the Belgian implements of this type appear to come within 
three different classes, answering generally to the three uses 
of striking, scraping, and boring. 
Most of the Eaton Eoliths are formed of a half or smaller 
portion of a flint pebble which has been broken in two or 
more pieces. Only in a few instances has the flat under portion 
been chipped. As a general rule most of the crust is left on 
the top and the chipping has been done round the edges of 
the flint. In many respects it differs from the hacking of 
the Kentish Eoliths and is undoubtedly a decided stage in 
advance, for there are, on practically every implement, 
signs of genuine flaking, some of the narrow strips of flint 
thus removed being nearly three inches in length. With 
a somewhat limited number of specimens it is impossible to 
generalise accurately, but certain types seem to recur. There 
are scrapers of irregular form, but with one end abraded, 
apparently by use, as the other edges are sharp ; big borers, 
the points being made by chipping a hollow on each side ; 
massive square-ended implements ; and others, bearing a 
family likeness to the axes of the Paleolithic period, though 
lacking their finish. Similar implements, “ between the typical 
Eoliths and the earlier Paleoliths,”* appear to have been 
found in the valley of the Darent, West Kent, where the 
chipping is finer and types more numerous than in the earlier 
examples from the true plateau gravels. One implement 
“ shows work on all edges, with slight attempts at flaking, 
and at one extremity there is a curved portion resembling 
the concave scrapers of Eolithic gravels.” This describes, 
fairly accurately, the first implement found at Eaton. 
According to a table given by M. Rutot f the Kentish plateau 
Eoliths belong to the Middle Pliocene, and those of the Cromer 
Forest-Bed to the Upper Pliocene, both, of course, in the 
Tertiary period. In the Quaternary period come the Reutelien 
and Mesvenien industries, both, in Belgium, characteristic of 
the first ice-period, the former marking its waxing and the
