 idea of the size of the place. Grounds with the boun- 

 dary shut off by masses, and these arranged with irregular 

 outlines, will look larger than they would if the boun- 

 dary line were plainly in sight.

 a thicket with small shrubs. 



It is usually the case that, no matter how few trees,

 Three, four, or six, for instance, will serve a better pur-

In all work of grouping, a leading aim should be to
