LANDSCAPE GARDENING 



Fig. 202. An effective screen of spruce trees. 



vistas be carefully preserved. Plantings should conceal 

 the defects and enhance the value of those parts that are 

 most pleasing to the eye. 



Mass Planting. To obtain the desired unity, character, 

 variety, and naturalness, the gardener relies mainly upon 

 the use of masses. Single specimens or groups may be 

 sparingly used, but only to break the monotony or to gain 

 some special character in the design. .Masses must be 

 carefully designed to become expressive. The plants 

 composing the mass should be selected with care. Each 

 mass should consist only of a few kinds of plants. Where 

 the mass is small it is well to select but one kind, while 

 in larger masses more than one kind may be used to ad- 

 vantage. Even in the larger masses, plants of the same 

 kind should be grouped together.
