 they must have been removed again in the diluvial period. 



B. The White Clay. 



While the lignites and their alternating clays present us with a 

 sub-tropical vegetation, the plants of the White Clay exhibit a totally 

 different character, and must have had their origin in an altogether 

 distinct period. 



Four species three of Salix and one of Betula have been found 

 in this overlying mass, no one of which appears to differ from species 

 now living. The presence of the Betula (B. nand) is conclusive for 

 a diluvial climate, that is, a colder climate than Devonshire has at 

 the present day ; for this dwarf birch is an Arctic plant, which has 

 no British habitat south of Scotland, and which occurs in Mid Europe 

 only on mountains and Sub-Alpine peat mosses. The evidence of 

 the willow-leaves is to the same effect, indicating that at this period 

 Bovey Heathfield was a cold peat-moor.
