series of deposits, resting on the chalk, is made up 
of a gravel, a greenish clay, and a chalky loam or 
marie. The worked flints found in this series belong 
to an older culture than the Chellean — they are pre- 
Chellean. The second series of deposits is represented 
by a gravel and an overlying bed of light-coloured sands 
yielding flints of the Chellean period. The third series 
of deposits begins with a seam of flints, or gravel, 
containing implements of the first Acheulean ^ culture ;

in the overlying bed of red, sandy, laminated loam — 
"limon fendille" — occur the later Acheulean implements 
of the type found in the brick earths at Bury St Edmunds. 
Often in the deeper layers of the last-mentioned stratum 
occur black bands of manganese. At the Carpentier pit, 
as at the Barnfield, the series of deposits end with the 
late Acheulean culture ; but in other sites in the same 
terrace, and particularly in the lower or 50-foot terrace, 
deposits of a later date occur, containing implements of 
the Mousterian, Aurignacian, and even late Palaeolithic 
cultures. Our visit to Abbeville assures us that in the
