SHADE-TREES IN TOWNS AND CITIES

 height, denuded at the base; to be

Keeping- Crown Within Limits. 

 Street-trees, however, should 

 not be permitted to grow beyond 

 certain bounds, for a number of 

 reasons. It is desirable to restrict 

 the spread of trees when they 

 begin to touch houses or extend 

 over the roadway so as to give 

 too much shade. To maintain a 

 compact crown on some trees, it 

 is necessary to shorten the ends 



Such formal treat- 

 ment of trees is a 

 matter of taste; but 

 trees always appear 

 more interesting and 

 exhibit more individ- 

 ual character when 

 their natural mode of 

 growth is preserved 

 as much as possible. 

 In this country the 

 training of trees into 

 unnatural symmetri- 

 cal shapes is little 

 practised.

 headed back to three-quarters of 

 the original height, with the lateral 

 branches shortened in proportion.
