cut, is generally similar to that of the broken surface of the other 

 flint fragments with which they are associated, and presents a light- 

 buff or cream-coloured patination, sometimes bluish, or with the 

 natural colour of the flint little altered. Frequently one side of 

 an implement will have a different patination from the other. 



The general conclusion seems to be that most, if not all, of the 

 implements belong to the same palaeolithic date. It is worthy of 

 note that fragments of quarlzite are occasionally found which appear 

 to have been hollowed at the edge and used for scraping or 

 rubbing. This is of interest as indicating that the fragments in 

 question, if the hollowing be artificial, were used by Man after such 

 glacial conditions had set in as produced their transport to this 

 district. 



In order to form an idea of the original thickness of the gravel at 

 this point, allowance must be made for the removal of a considerable 

 quantity by denudation, which, owing to the contour of the ground, 

 would necessarily be rather severe. That the gravel which has 

 been removed contained some implements seems probable, from the 

 occasional occurrence of a specimen at a lower level. 



This is, I believe, the highest point at which so far the valley- 

 gravels of this district have yielded traces of Man. Animal remains 

 are rare. I have not met with any, but Mr. L. Treacher informs 

 me that he has found at this pit a much decayed tooth of horse, and 

 a few small fragments of bone also in a decayed state. Prof. 

 Prestwich and others have suggested that the rarity of the occurrence 

 of mammalian remains in the older high-level gravels is due to their 

 gradual destruction by percolating water. 



I have obtained an implement from a casual opening in gravel 

 about half a mile west of the Toots-farm section and at about the 

 same level. 



2. Henley Road^ Cave?'s7iam. 



There is a pit from which gravel and Chalk have been extracted 

 on the east side of the village, about a mile distant from the Thames 

 and about 168 feet above sea-level. The section shows a very 

 uneven surface of Chalk, which is ravined, and overlaid by a clayey 

 gravel, showing stronglj^-marked bedding in places, and in other 

 places looking like a " wash." In one place there is a thin patch of 

 sandy gravel resting on the chalk-rubble, which I take to be a relic 

 of a once larger deposit and to be older than the mass of the gravel. 

 Prom this part I have obtained a flat ovoid flint implement, much 

 abraded, and a few other worked flints. The type is unlike that of 

 the implements from the Toots-farm gravel, and resembles those 

 obtained from the opposite side of the valley. A molar of Ele].)lias 

 primic/enius, in a decayed state, was found here. 



3. Shiplakc. 



About three miles from the last-mentioned locality there is a 

 terrace of gravel occupying a level of about 200 feet above sea-level, 

 a section of which, in a pit by the side of the road to Henley, shows
