and other pieces down to very minute stones (very many show 

 the above-mentioned striations) ; a number of small white, whitish- 

 ochreous and ochreous tiints, somewhat rolled ; and certain sharp 

 and unabraded pieces. Of the latter class it is in my opinion 

 impossible to find a piece on which the fractures are not due to 

 man : except it be a small proportion of implements, and, perhaps, 

 an occasional other piece, which have evidently split in two along 

 a line of weakness in the flint. The two parts of these broken 

 tiints probably do not finally separate until they are dug out with 

 tlie rest of the gravel; and of by far the majority of the flints in 

 this stratum, except the small white and ochreous pieces and a few 

 pebbles, it would be difficult to say that they had not been chipped 

 and hammered and flaked by man. Occasionally a pebble of 

 considerable size may be found and sometimes a piece of sarsen 

 or other non-flint stone. These various constituents of this loose 

 drift seem to be mixed promiscuously, and the implements are 

 found at depths varying several inches even within a small space. 

 But there is in places one thin portion of this stratum which 

 contains a larger proportion of fine sand and tiny flints than the 

 rest of the stratum. This thin layer produced an innumerable 

 quantity of minute flakes and micro-liths. Some of the former are 

 so small that they can scarcely be picked up with the fingers. 

 Some of the latter are trimmed by minute marks along the edges 

 and are very tiny, and others are distinctly flaked. Like the 

 implements, some are abraded and some are sharp and unworn. 

 Some are brilliant with the peculiar gloss for which this pit is 

 famous. The implements of normal size, discovered in this portion 

 of the drift, are sharp, and black -grey, medium, or very light grey. 

 There are also rolled, abraded, and striated implements of varying 

 colours and conditions. Apparently the tools which lie in or above 

 this drift are liable to show more or less white on their faces or 

 on one face, which goes to prove that they have lain for some time 

 within reach of moisture from the surface of the ground. But 

 many show no sign of decay. The river silt rests on ochreous 

 gravel. Whereas the former is loose and sandy, the latter would 

 seem to contain some element of clay. The fine sand of the silt,
