TOPOGRAPHY OF BLAKENEY POINT. 7 



system (the most extensive of all) rests on the Headland a 

 number of crowded stabilised banks to the West. 



Between these two systems is a deep bay occupied by the 

 Pelvetia Marsh (P.M., Fig. l). This marsh is divided into a 

 number of arms or compartments by low lateral shingle banks 

 on the North-west side (Fig. 4). These in general are of the 

 same character as the banks on the Marams, except that they 

 are lower and bear a less complex vegetation covering ; one of 

 them (No. 22 in Fig. 2) is shown end on in Fig. 5. 



Between the two Long Hills banks, 3 at their distal ex- 

 tremity, is a smaller salt marsh (H.M., Fig. 1) of interest as 

 being the only locality on the Point for Statice humilis. 



From this purely topographical summary of the main features 

 of Blakeney Point we may pass on to consider the mode of 

 development. 

 THE MOBILE AND STABILISED SHINGLE BEACHES. 



In a general way (though subject to some reservation in 

 special cases) shingle washed" by the open sea remains in a 

 state of mobility ; that is to say, storms throw shingle over the 

 crest and scatter it down the lee slope. By the repetition of 

 this operation the whole of the length of the main beach is

being slowly driven shoreward, whilst the materials of which it 

 is composed are not permitted to remain at rest long enough 

 for a permanent, continuous carpet of vegetation to become 

 established. What applies to the main beach also applies to 

 its extremity deflected as a landward hook by the scour of 

 the tide. When, however, the main beach resumes its old line 

 of advance the new apical deflection which it in due course

 reference to a house-boat of that name moored alongside.
