96 NATURE IN DOWNLAND 



Once only in the South Downs have I seen the 

 lizard's worst enemy, the smooth snake. He is like 

 the creature he pursues, alert and quick to escape, 

 and may not be quite so rare as we imagine. 



The adder is common in suitable places, on the 

 high slopes, especially where the gorse bushes grow

 and made drowsy or lethargic by the unaccustomed 

 heat of the sun. In early spring he is on the con-
