two quite well marked types of soil. The fields yellow with 

 the Buttercup, indicate heavy clayey soil and what is of great 

 importance to tjhe farmer, a good crop of grass. On the other 

 hand the Daisy indicates a lighter, drier, and poorer soil, and 

 a poorer grass crop. These two types of grassland are marked 

 off in the main by the Kame-like ridge running from Speeton to 

 Sanwick ; the fields inland from the ridge being dominated 

 mainly by the bulbous Buttercup, while in those between the 

 ridge and the coast the Daisy is the conspicuous flowering plant. 

 These are connected by an intermediate type in which neither 

 plant gains preponderance.

The Danes' Dyke provides an interesting illustration of 

 change of species due to environment. On the summit of the 

 high ridge are many dry-loving species. These give place on 

 the slope to species requiring greater protection, and in the 

 hollow is every gradation from meadow to marsh and aquatic 

 plants, according to water supply. The Gorse was often abun- 

 dant on the ridge together with tree-like specimens of Broom 

 with stems 4 to 5 inches in thickness. Along the fringe of the 

 coast everywhere capped with glacial drift and often covering 

 a considerable part of the slope, the prevailing plants are those 

 of the adjoining pastures. 



The following list of species at Bempton Cliffs is fairly 

 typical : — Sheeps Fescue Grass abundant ; Cocksfoot and 

 Smooth Meadow Grass common ; the four Plantains, Ribwort,
