232 On the Recent Discovery of Flint Implements 
posed of coarse green-sand chert. This kind of chert is more 
tough, although less easily worked than flint; and hence probably 
compensated by this quality for the additional trouble required to 
chip it into shape. 
The size of these implements offers almost as great a variation 
as their form. The smallest pointed example from Highfield near 
Salisbury, measures rather less than 22 inches in length, whilst 
the largest from Milford Hill is 83, and another specimen from 
the same locality which has unfortunately lost its point, would 
when perfect, have measured at least nine inches ;' but by far the 
most common form is only half this size. 
The workmanship in many cases is excellent, the weapons being 
formed by the skilful chipping off of a very great number of small 
flakes, a process which gives a symmetry of outline and a strength 
of body attainable by none but well practised hands. In looking 
over a large series however, one has frequently noticed the few bold 
strokes which have been sufficient to form implements evidently 
intended for some temporary use. Mere rudeness of workmanship 
is of course not sufficient to condemn these as accidental forms, the 
evidence of design, indicating the adaptation of a given stone to a 
certain definite purpose, is the point which stamps these rude efforts 
as the result of human work, and human fore-thought. 
But Mr. Evans has pointed out that if further evidence were 
needed, the link would be found in the fact that many show traces 
of actual wear, both in a blunting of the cutting edge, shown by 
a number of fine chips, and also by a certain alteration of the 
original shape, probably produced by the repointing of a broken 
tool, which gives a stunted and peculiar form very like what is often 
seen in the finely chipped and easily broken stone daggers of 
Denmark. 
There is also a point which affords a very strong argument in 
favour of the peopling of this island by one race, or a series of 
closely allied races, during an extended period of time. It is the 

1 Mr. J. W. Flower has lately obtained from the gravel of Red Hill, Thetford, 
a remarkably fine implement which measures 112 inches in length: this, I 
believe, is the largest specimen hitherto discovered in the drift.
