not, however, commanded by any immediate high ground, but, on the contrary, possesses 
an open and unobstructed view for some distance around, and is then separated, by a 
slight depression, from the higher hills to the southward. The pits are of considerable 
extent, and have been long worked for brick-earth, sand, and gravel. The total thickness 
of all the beds, which repose upon a very irregular and eroded surface of chalk, varies 
h’om about 20 to 30 feet. The worked flints are found chiefly in the lower bed of 
gravel, more particularly in the lower part of it or near the chalk, where also the greater 
number of bones are found, but this is by no means a general rule. A considerable 
number of teeth and bones are also met with in the sand and marl above the gravel. 
The upper brick-earth (J' and If) has been very generally removed, so that it is only 
in a few places that the entire series of beds is seen, as for example, by the well in 
T. Feeville’s pit (flg. 5), near the Cagny road, at which spot they are not only more 
complete but more regular than usual. Further on in the same pit (flg. 6) the brick- 
earth has been removed, and the lower beds are more irregular. At Waeeaj^’s pit, at 
the further extremity of the field, is another section complete from the surface to the 
chalk (fig. 7). These three sections show the variations in the structure of the lower 
beds (c and d). In conjunction with figs. 10 and 11 (p. 299), they likewise well exhibit 
the variations in the beds, b*.
