The area investigated lies just inside the Wash, so that the 

 results are both comparative and supplementary to work at Bla- 

 keney another active centre for coastal ecology (cf. Bot. Cent. 126 

 p. 29 and 456). The introduction deals with the physical features 

 which have been carefuUy considered, and Charts show profiles of 

 the area and also changes in the coast-line at intervals since 1797. 

 The surface features of the Vegetation are presented in an excel- 

 lent map (scale 1:1584). Three plant formations are recognised: 

 1) Shingle formation, sparseJj^ represented as compared with Bla- 

 keney biit with several variations in development histor}»-; 2) Sand 

 Dune formation on shingle banks and beginning with Agropyron 

 junceum association; 3) Salt Marsh formation. This last is the chief 

 formation of the area, and presents a complete series of plant socie- 

 ties: 1) Salicornia-Glyceria, 2) Gly ceria- Aster Statice, 3) Statice, 4) 

 Armeria with subdivisions, 5) Festuca-Juncus, 6) Pools and Chan- 

 nels, 7) Glyceria-Obione on sand. 



Special attention has been given to soil excavations, the results 

 of which are charted to show depth of shingle, mud, sand, black 

 sand, etc. in the various sections. These have given Information on 

 the origin of the marsh, and also explain certain transitions from
