3 oo Deposits containing Flint Implements, [July, 
have, at the points c and d of general section, typical sec- 
tions of the clay-pit, as shown in Fig. 7. The clay, 4 in 
section, is called “ red brick earth ” by the workmen, be- 
cause it burns to a red colour ; whilst the lower dark-coloured 
clay, 7 in section, is called “ white brick earth, 5 ’ because it 
burns to a white colour. The bottom of the latter bed has 
not been reached, although Prof. Prestwich had a boring 
put down into it to a depth of 17 feet. It is full of vegetable 
matter, and I found numerous pieces of wood in it. The 
men pointed out to me the gravel seams, 5 in section, as the 
horizon at which flint implements had been found ; but 
shortly before Prof. Prestwich visited the pit, two specimens 
had been taken from the lower part of the clay, 4 in section. 
There can be little doubt, however, that they were found by 
Mr. Frere in the gravel below the “ red brick earth,” as he 
says that— <£ They lay in great numbers at the depth of

top and graduating downwards into obscurely stratified chalky clay : 10 feet. 
5. Two thin bands of small chalky gravel, separated by 8 inches of loam. 7. Dark 
calcareous clay, with fragments of wood and other vegetation. 
about 12 feet in a stratified soil, which was dug into for the 
purpose of raising clay for bricks. Under a foot and a half 
of vegetable earth was clay seven and a half feet thick, and 
beneath this one foot of sand with shells, and under this 
two feet of gravel, in which the shaped flints were found 
generally at the rate of five or six in a square yard. The 
manner in which the flint implements lay would lead to the 
persuasion that it was a place of their manufacture, and not 
of their accidental deposit. Their numbers were so great 
that the man who carried on the brick- work told me that, 
before he was aware of their being objects of curiosity, he 
had emptied baskets full of them into the ruts of the ad- 
joining road.” 
As I have already mentioned, the place at which the clay 
is now excavated is some distance from that where Mr. Frere
