England, as for instance at Bury St. Edmund, these same low 
level gravels have proved very productive of flint implements. 
But to return to these very interesting objects, the flint imple- 
ments themselves, they have been found in Wiltshire chiefly in 
the high level gravels of ,the various places before enumerated, 
sparingly in some, more abundantly at others, especially at 
Milford Hill, which in productiveness has rivalled some of the 
most celebrated Continental localities. They are found occupy- 
ing various levels in the gravel, some at but a few feet from 
the surface, others occur in a middle position, whilst perhaps 
the greatest number are found near the base of the deposit, 
a few absolutely resting in the pale fawn coloured chalk rubble 
immediately above the undisturbed chalk. The implements form 
part and parcel of the gravel and are stained and water-worn 
in the same manner as the unworked flints: in no instance has 
there been observed the slightest indication of any~ excavation 
or disturbance of the gravel subsequent to its first deposition. 
During the excavations on Milford Hill, very many worked flints 
-were seen absolutely ‘‘in situ,” a fact we owe to the great interest 
and most laudable industry exhibited by many collectors, but more 
especially to the individual researches of Mr. James Brown and 
Mr. Wheaton. 
The surface of the weapons varies considerably: the majority 
are water-worn and show evident traces of having travelled 
some distance in very rough company, bearing marks of many 
a hard knock and jostle by the way; others have the angles of 
the chippings as sharp and well preserved as if they were made 
but yesterday. Some are stained of a deep yellow colour, others 
only partially so, and some not at all. It is remarkable that 
this staining does not appear to be due to their present position 
in the gravel, some of the darkest specimens have been dug 
out of the pale chalk rubble, side by side with fragments of 
flint retaining its original hue: and on the other hand, perfectly 
unstained examples have been obtained from the dark ochreous 
gravel. Nearly all present a greater or less amount of dendritic 
markings due to the peculiar form which the mixed oxides of Iron
