This is the last section in the Valley Deposits, for 50 yards 

 further on they thin away against the rising slopes of Afton 

 Down, and do not touch the coast again till we reach Freshwater 

 Gate. 



At Freshwater Gate the cliff cuts across the old valley at right 

 angles, giving a clear section of all the river deposits, except the 

 modern Alluvium whicii lies at and below the sea-level. The 

 section has long been noted for the finding of two teeth of 

 SJlephas primigejiius in the gravel as described in detail by Mr. 

 Godwin Austen.^ 



On the west side of the valley (Fig. 80) the lower part of the 

 gravel is composed of large partly worn flints, with chert and 

 ironstone, and is stained and partly cemented by iron-oxide. 

 Above this rock a grey stratified chalky loam overlaps the flint- 

 gravel, and rims up the slopes of chalk above it, much as a rain- 

 wash would do. Nearer the middle of the valley this chalky loam 

 is overlain with brown loam and brick-earth, but, still lower down, 

 thins out, leaving the brown loam resting on the flint-gravel. The 

 section now exposed at the Bath House shows — 



Brown loam .... 

 Flint gravel, with a few bands of sand or grit
