If the scarp is of actual rock there is no need forlthe 

 wall except in cases where the strata tip down forward, 

 when plants could not be comfortably grown. But in 

 such a case it would be better to have some of the 

 wilder clematis or roses planted at the top to wreathe 

 and trail over the rocky 

 surface. 



The steps that 

 accompany dry walling 



can be made 



in a very sim- 

 ple way, if it is 



desired to save 



the expense, 



both of stone 



and labour, 



of paving the 



whole surface. 



The front edge 



only need be 



of stone, as 



shown in Figs. 



163 and 165 ;
