 Head, sandy and very angular, 

 Blown (?) sand, among rounded blocks, 

 Rock-platform. 

 The sand is a fine, horizontally-bedded sand, very much 

 resembling blown sand, and lying on the platform among the 

 rounded blocks. Further seaward, there is a little pre-glacial 

 beach-gravel lying among these blocks. 



About 100 yards west of where the stream enters the sea, a 

 water- worn knob of rock, 6 feet high, has its base (the ordinary 

 level of the platform) 5 feet above the line of seaweed, i,e. 2 to 3 

 feet more or less above ordinary high- water mark. Section here: —
