1898] A UTHENTICITY OF PL A TEA U IMPLEMENTS 107 



instances in which the flint has been artificially flaked into the 

 form of a weapon." This, of course, is incorrect {vide Natural 

 Science, vol. iv. pp. 261 to 265). Here also (see accompanying 

 Plates) are two instances in which the form is a very passable, 

 rough spear-head, allowing for the blunting of the edges by abrasion 

 in a river channel. No. 18 is from the plateau at Sepliam Heath. 

 No. 19 is from Broom Ballast Hole, Devon. No. 20 is a similarly 

 worked neolith from Preston Farm, Shoreham. The Th'oom imple- 

 ment is of chert, much abraded evidently in a stream. No. 44 is 

 put in for contrast. 



Mr Cunnington again states (p. 332) that " wliy Eolithic man 

 should have worked only on one surface of the stone is not ex- 

 plained." In general perhaps he did, but always he did not. 

 Nos. 7 to 14 are a series of drills or ' rimers,' which, commencing 

 with Eolithic man, pass on to Neolithic forms, and find their con- 

 summation in the nineteenth century engineer's bit. In all these 

 specimens the surface of the flint is worked in one direction on one 

 side of the point, and in the opposite direction on the other side, so 

 that, in boring, the cutting edges of each side of the point follow 

 each other exactly as the cutting edges of an engineer's bit do. 

 Nos. 7 to 11 are eoliths. Nos. 12 to 14 are neoliths. These 

 also occur, of chert, at Broom, Devon. 



Again, Mr Cunnington says, " if the flints were worked, used, 

 and then thrown down again, we should expect them to be widely 

 scattered." So they are. In addition to the classical localities of 

 Mr Benjamin Harrison, and also of Messrs W. J. Lewis Abbott, de 

 Barri Crawshay, Montgomery Bell, H. Lewis and A. S. Kennard, I 

 append a list of places at which I have found worked flints and 

 chert of the plateau types : — 



Above 600 feet contour line, Stockham Wood and Sepham 

 Heath ; above 500 feet contour. Shepherd's Barn, Preston Hill, 

 Great Northfield, Goodberry Farm, Well Hill, Halstead, Borstal 

 Hill, all in Kent; above 450 feet, Cockerhurst (Kent) and near 

 Amersham, Bucks. Derived specimens, in valley gravels or on 

 surface, Eampisham (Wilts), Micheldever (Hants), Broom (Devon), 

 Jumper's Heath and Bromwich (Hants), Aylesford and Stud Hill 

 (Kent), Cadamy's Pit and Eailway Cutting, Wells, Norfolk, Mau- 

 tort and St Eiquier, near Abbeville, and St Acheul, near Amiens. 

 The character of these implements, wherever found, is of the same 

 primitive type as Mr B. Harrison's South Ash and other specimens. 



Those found on the plateaux are in patches of old praepalaeo- 

 lithic high level river gravels left isolated and discontinuous by 

 later earth-sculpture. 



Mr Cunnington objects to the uselessness of the shapes into 

 which they have been made. I think that if Mr Cunnington had
