14 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
