 interpretations. 



Of these bunnys there are two. The first, which bears also the 

 more grandiose title of " glen," is that at Chewton. The base of 

 this bunny is not cut to the sea level but terminates in a cascade of 

 some little height which is now artificially confined and supported. 

 Its eastward neighbour at Becton, as I pointed out to a party of the

Society on a recent occasion, is worn well down to the beach, through 

 which the little brook percolates to the sea. In both these cases 

 there is a well-marked valley slope above, at the base of which the 

 precipitous bunny is cut. The change from the gentle slope to the 

 abrupt is quite sudden, is not referable to any change in the strata, 

 and would seem clearly due to some sudden alteration in the con- 

 ditions of the streams themselves. The outline of the sea-front of 

 Becton Bunny, as shown in fig. 3, though not drawn to any scale, 

 which is not the purpose of the diagram, shows quite truthfully this 

 abrupt change. It can only be actually seen from a boat a short 

 distance out from shore. 



The most reasonable interpretation appears to be as follows. 

 The destruction of the old Frome-Solent valley by the lateral in- 

 cursion of the sea must, as soon as the process had reached the
