Cf. Martial, XLV, 51.— 
“ Pergamus has misit, cwrvo destringere ferro.” 
§XIL. Koliths: their Geological Age and their History.— 
Our interest in the rude ochreous implements of the Kentish 
plateau centres in their unique position, at a higher level 
than the Pleistocene High-level Gravels, and in thei con- 
sequently greater age, ante-dating the Glacial Epoch. When 
Sir Joseph Prestwich, having finished his monumental work 
on geology and resigned his Oxford Professorship, was able 
to devote himself to local geology, his prescience at once 
discerned this fact, and his writings are storehouses of infor- 
mation on this subject. 
These eoliths have been found at levels from 400 to 700 
feet O.D.* by their discoverer, Mr. B. Harrisonf, by Mr. de 
Barri Crawshay,t Mr. Montgomerie Bell,f Mr. W. J. Lewis 
Abbott,§ Mr. Santer Kennard] Mr. O. A. Shrubsole,# Mr. 
1. Stopes, Mr. A. E. Salter, Mr. Lasham, by myself,** and 
others. 
In 1894 the British Association made a grant for excava- 
ting on the crest of the North Downs in a carefully selected 
spot, under a Committee consisting of Sir John Evans, F.R.S., 
Professor H. G. Seeley, F.R.S., and the late Sir Joseph 
Prestwich, F.R.S., under which committee Mr. B. Harrison 
worked, carefully recording the progress of the excavation 
of the various pits sunk under their direction. 
In a pit sunk on Parsonage Farm, Ash (Pit No. I), the 
following section was clearly made out to my own know- 
ledge :—
