 but could be made to harmonize with a more gar-

 lar branches, brQliant coloring, and general in- 

 formal appearance, would not do at all for city 

 planting. 



In the citr home the selection of trees and 

 shrubs is not controlled br natural features, such 

 as existing plant material and contours, for dty 

 conditions are artificial, and a natursdistic treat- 

 ment would serve ouIt to accentuate the artifieial- 

 itr. Evergreens, provided they can withstand 

 smoke conditions, may here be used to advantage, 

 considering them as units of a whole mass rather 

 than as a natural part of their surroundings. 

 They seem to have an inherent stlSness which fits 

 them for artificial conditions. 



Trees and shrubs in dty planting are useful only 

 for contrast of form and color. Woodland condi- 

 tions would seem as nmch out of place in stiff city 

 surroimdiugs as would a collection of topiary 

 work and hybrid roses under natural forest condi- 

 tions, because its very nature would lead one to 

 question its appearance among such uncongenial
