TREES FOR SHELTER. 



Scarcely a _ocation can be selected where there is not 

 some point that needs protection or shelter from prevail- 

 ing winds or from storms, and generally only those trees 

 that are very hardy and provided with an abundance of 

 thick tough foliage should be used. They are more com- 

 monly planted on the north or west exposure, and should 

 be set as closely as possible and have them grow to a good 

 degree of perfection. If- immediate shelter is needed, close 

 planting may be advisable, but the surplus trees should be 

 removed as soon as they begin to interfere with the perfec- 

 tion of those desired for permanent growth. It is always best 

 to plant those that are the most desirable for permanent 

 growth at the proper distance for full development, and 

 then arrange the more temporary kinds so that they may 

 be finally cut out. In this work, as in all grouping of 

 trees and shrubs, it is best to obtain as much contrast and 

 variety of form and color as possible, and yet have a 

 pleasant blending of all the characteristic features. 



Evergreens are generally planted for purposes of shelter, 

 as they hold their foliage during the winter, though a mix-

 satisfactory picture. The evergreens, especially when 

 massed, produce a sombre effect, which is lightened and

 the birches, golden willows, etc. 



The larger and more stately trees should be set at the
