234 GEOLOGY OF THE ISLE OF WIGHT. 



Ill an outlier between the cliff and the old course of the stream.

Grey silt, with stones - - - - - 



Flint gravel ------ 



Gravel, chiefly of fragments of Wealden Beds 



The mode of occurrence of this deposit leads to the inference 

 that it is of the same age as the Alluvium at Shippard's Chine, 

 where also nut-shells are imbedded. 



Whale Chine forms the outlet for a small stream taking its 

 rise in the western slopes of St. Catherine's Down. The sides of 

 this extremely precipitous ravine are capped, like those of 

 Shepherd's Chine, with an alluvial deposit, consisting of loamy- 

 beds above, and gravelly beds below, the majority of the stones 

 in the latter being chert and ferruginous sandstone. The sub- 

 joined section may be seen at the top of the cliff, on the north 

 side of the chine : —

On the north-east side of the Military Road, the chert gravel 

 comes to the surface, and has been dug for road-metal. On the 

 south side of the chine it is overspread by Blown Sand, which 

 will be described subsequently, but the gravel can be traced 

 beneath this covering in the face of the cliff for about three- 

 quarters of a mile, rising south-eastwards from about 145 feet 

 above the sea at Whale Chine to about 200 feet at Walpen 

 Chine. The following sections were noted in it : —
