TOPOGRAPHY OF BLAKENEY POINT. 
individual members of which are arranged in sequence of age. 
It thus becomes possible to follow each type in proper historical 
order through all the stages of its physical establishment, 
colonisation by plants, and the “ successions ” which these 
undergo. Indeed, it is hardly possible to imagine any area 
that could be better adapted to such a purpose. 
These introductory remarks may be closed by some reference 
to the nature of the changes now in progress on the Headland. 
Recent Changes on the Headland and Long Hills. 
The earliest available map with topographical detail 
adequately represented is the six-inch map of the Ordnance 
Survey, published in 1886. A somewhat schematised reduc- 
tion of this is reproduced, with two maps of later date, in 
Fig. 3. Shingle and shingle overlaid by bare sand are given 
in black, whilst the dune systems are dotted. The salt 
marshes (M.) which occupy the two principal bays have not 
been distinctively marked on the maps here given. It will be 
noted that the shingle continues more than a quarter of a mile 
beyond the sand hills, and that it bears several hooks. At the 
top of the map two spurs of shingle are represented, and on 
the extreme right yet another. 
The 1897 map shows considerable change. The bare 
apical system of shingle is now represented by a single 
attenuated hook that has swung round nearly forty-five degrees 
to the South ; the hook guarding the West side of the mouth 
of the Pelvetia marsh, that had in 1886 a single L-shaped 
terminus, has now budded out a second terminal : the two 
spurs at the top have coalesced with the main system, whilst 
the excrescence to the right has disappeared. Elsewhere there 
is little change to merit comment, except, perhaps, the wasting 
of the expansion at the end of the more westerly of the two 
Long Hills banks. 
Turning to the 1911 map (based on our own surveys), the 
disappearance of the apical hook will be noted. As recently as 
1907 this hook still existed as a topographical feature, though 
bent round so as to lie nearly parallel to the edge of the main
