 In very crowded cities, indeed, such a wall be- 

 comes the larger part of the garden, since only 

 a tew kinds of plants will live in the atmosphere, 

 and wall tiles, recessed bits sheltering sculp- 

 ture, wall fountains and seats must provide the 

 color, interest, and beauty usually furnished by 

 them. 



Variation in the height of a wall wherever 

 there is a real reason for it — that is, at a point 

 where the contour of the land or where a turn, 

 or a junction with some different section of the 

 garden, or some other element of change makes 

 it logical — is pleasing usually, and sometimes is 

 almost necessary; especially is this felt when a 

 wall entirely surrounds the grounds. One break 

 alone will suffice, many times; or even the vari- 

 ation that comes of a gateway. But this much 

 at least is needed to avoid monotony and the 

 sense of grim (overdone) defense. To extend a 

 wall some distance from the house at a consid- 

 erable height and then to decrease this height 

 is one way of achieving the necessary variation. 



Of course a study of good examples is just 

 as essential to intelligent and discriminating 

 selection when it is a wall for the garden that 

 is under consideration as when it is the house 

 itself. So without regard to preconceived ideas
