Investigations at Knoiole Farm Pit. 



Hank obliquely the left end of the platform, and of the face of the 

 gravel. 



In the autumn of 1904 the men had occasion again to dig out 

 river silt at a spot on the platform edge where some of it still 

 remained. At times, when they were not working in the hole 

 thus formed, I took the opportunity of raking out stones with one 

 of the gravel-facing forks which they lent me. I stood in a hole

usually 6 feet deep, sometimes more, sometimes a triHe less. At 

 the top was a greater or lesser quantity of " dirt." This dirt con- 

 tained rolled and abraded Palseolithic implements. Their general 

 appearance is blue-grey and thick white, and they bear interlaced 

 short striations. Beneath the dirt there occurred sometimes a 

 jumbled mass of rolled flints of considerable size mixed with fine 

 silt. The mass was " hard " and difficult to pick out. Where this 

 conglomeration attained a thickness of more than a foot or two 

 there would seem to be but little undisturbed river silt beneath. 

 Where, however, the hard gravel was comparatively thin, or not 

 so coarse, there lay the fine river silt beneath it, containing sharp, 

 unrolled and perfect implements, as well as others which were 

 abraded. My practice was to leave the hard gravel for the most 

 part alone and to rake out the stones and implements from the 

 loose river silt beneath it. 



Doubtless the hard and the loose material are the same drift 

 under different conditions : the one disturbed by some subsequent 

 movement, perhaps of an icy river ; the other comparatively 

 undisturbed. 



The loose silt contains more or less rolled flints of a fair size
