594 ON THE VALLEY-GRAVELS ABOUT EEADINtf. 



It "will be seen from this Table that there is a somewhat wide 

 range of height above the nearest river-level in the case of the 

 gravels containing relics of Man, namely from 40 feet to 114 feet. 

 While it is evident that Man was in the valley certainly as far back 

 as when its level stood 114 feet higher than at present, we cannot, 

 owing to the shifting nature of valley-deposits, positively say that 

 the occupation continued down to the date represented by the lower 

 level of 40 feet, although it may have been so. 



With regard to the larger mammalia, the evidence here seems to 

 accord with that from other districts, their remains having been 

 found at lower levels than the implements fabricated by Man. It 

 may therefore be inferred with some degree of probability that those 

 animals remained in the valley for some time after Man had left, 

 if the chronological indications of valley-deposits could in all cases 

 be relied on. 



Discussion. 



Mr. MoNCKTON had noticed great variability of the gravels around 

 Heading, and would like to learn whether it was possible to trace 

 the gravels shown in the section at Grovelands for any distance 

 laterally. 



Mr. Aebott could not understand from the section displayed that 

 the Groveland gravel belonged to the Thames system, dipping, as it 

 did, to the valley of the Kennet ; a continuation of the line of dip 

 appeared to take it over to the higher-lying gravel on the north, 

 making it appear as if the two gravels were the same, and had been 

 cut through by the Thames valley. 



The Author said that the variations had, to some extent, been 

 traced laterally. The appearance of dip towards the Kennet in 

 the section referred to by Mr. xibbott was misleading, as the section 

 was diagrammatic. He did not expect contemporaneous gravels to 

 be discovered on both the Oxford and the Berks side of the river. 

 The gravel referred to was distinct from that at Caversham, and 

 both were essentially valley-gravels.
