tides. And not only is the material shot over, but it is also 
driven down the lee slope by the breakers, commonly emerging 
on the fringe as a projecting talus fan. This is the typical 
procedure all along the Marams — the fans or fingers (Fig. 6) 
projecting over the saltings and there remaining in situ on 
account of the protection from scour afforded by the hook- 
shaped lateral banks. Successive storms (it may be after the 
lapse of years) reinforce identical fans with additional shingle. 
This constancy in the dynamic lines of travel is of course 
referable to the permanance of the gaps between the Suceda 
bushes (well established on the Marams), which act as lines of 
least resistance. 
Now, that part of the main bank to the East of the Marams 
is without Suaeda bushes ; moreover, from Kelling to the Cley 
Channel it is backed by a sea wall to protect the reclaimed 
marshes. Throughout this section of the bank the travelling 
shingle becomes heaped up against the bank, and, in the case of 
the Salthouse marshes, at very many points has burst through 
the wall and spread in great fans, about two feet deep, over the 
actual surface of the marshes. 
As no effective means have been taken in recent years to 
repair the Salthouse bank, the condition described is going from 
bad to worse.' In contrast to this may be mentioned the 
section of marshes between Salthouse and Cley. Here the wall, 
evidently under difficult conditions and at considerable expense, 
has been kept in repair, with the result that it has been possible 
to exclude the drift of shingle up to the present time. 
From these marshes to the Marams (half-a-mile) the shingle 
bank has rapidly encroached on the unprotected Cley channel. 
The shingle stands as a cliff on the seaward flank of the channel 
some six to eight feet in height, but the projecting fans or 
fingers of shingle are washed away, as soon as formed, by the 
current which here undercuts the bank. As a consequence, the 
channel has latterly become much blocked by shingle and 
5. However deplorable this section of the bank may be from a purely economic 
poiDt of view, it is replete with instructive illustrations of the dynamics of shingle 
flow.
