12 TOPOGRAPHY OF BLAKENEY POINT. 



navigation rendered difficult. Furthermore, as a result of this 

 encroachment the waters of the Glaven tend to cut back the 

 saltings on the South bank of the channel an operation that 

 seems likely to persist. 



Passing on now to the state of affairs between the Marams 

 and the Hood. Much shingle is driven across this section, but 

 the fans are non-permanent, as the bay is an open one liable to 

 be swept by the wind and tide from the landward side. As a 

 consequence, a large part of the talus is driven into the corner 

 by the Watch- House bank of the Marams under the influence 

 of S.-W. winds a residuum going in the opposite direction 

 towards the Hood, drifted by winds from the S.-E. quarter. 

 What holds for this section applies in large degree to that 

 between the Hood and the Long Hills the bay here being 

 also open and unprotected. 



The general result is, of course, that these sections of the 

 bank are being steadily deprived of shingle and undergoing 

 attrition, so that they are in effect becoming danger spots in the 

 system places at which something of a drastic nature may be 

 expected to occur. 



A serious aspect of the matter is that no Suceda bushes are 

 able to establish themselves upon these sections. As we see 

 from the Marams (Fig. 12), the fans of talus during 

 intervals of quiescence are the great places for the establish- 

 ment of seedlings. In consequence of the scour in the open 

 embayments these fans are not permitted to remain, and 

 thus the fringe of the bank is kept continually on the move, 

 with the result just stated, that there is no spreading of Suaeda. 

 As the Suaeda is the most important factor in arresting the travel 

 of shingle, the employment of the word serious in this connec- 

 tion is not without justification. 



THE PLANT HABITATS. 



It will be evident from the foregoing that Blakeney Point 

 affords a great variety of different ..kinds of habitat for the 

 establishment of vegetation. There is the main beach, which,
