VALLEY-GKAVELS ABOUT BEADING.

considerable thickness, the)- occur near the bottom of the deposit, 

 as a rule, but occasionally dispersed in the mass. At Ruscombe 

 they are found, as stated (page 591), in the underlying clay. In 

 consequence of the discontinuity of the several gravels, there is 

 great difficulty in obtaining from them detailed and consecutive 

 data. Juxtaposition in a gravel does not necessarily imply con- 

 temporaneous origin ; and, as we might expect, there has been a 

 dovetailing of deposits, and a destruction and mixing together of 

 gravels formed at various dates. 



A list of localities exhibiting the typical gravels of the valley, 

 excluding those of the lowest levels, is appended herewith in order 

 to show at one view their approximate height above the ordinary 

 river-level at the nearest point, and their relation to the occupation 

 of the valley by Man and the other mammalia, so far as I have been 

 able to ascertain. 



It should be mentioned that the levels have been taken from 

 usually the highest point of each section at the surface ; but allow- 

 ance must be made for the varying contours of valley-deposits, and 

 for the fact that it has not been practicable in all cases to get the 

 exact level surveyed. 



I have, through the kindness of Mr. Thomas Eeed, of the Ord- 

 nance Survey at Reading, obtained the exact height above the sea- 

 level of the river-surface at two points, namely, at the junction of 

 the Thames and Kennet (116 feet), and at Caversham (120*77 feet). 

 Below those points the level of the river has been estimated. 



I take this opportunity of acknowledging my indebtedness to 

 Messrs. William Davies, P.G.S., A. S. Woodward, T.G.S., and E. T. 

 Newton, F.G.S. for the identification of mammalian remains at 

 various times.
