HARDY ORNAMENTAL TREES AND SHRUBS.

used, and the tree fastened to it firmly by 

 means of a band of rubber or plaited straw. 

 If the surface be a paved one, iron gratings 

 should be laid around the stems, large enough 

 to extend outwards from each tree for at least 

 3 feet in all directions, in order to admit air 

 and moisture to the roots (see fig. 416). 



The distance between each tree should be at 

 least 40 feet. It is not desirable to plant in 

 such a way as to necessitate the mutilation of 

 the trees when large to prevent their interfer- 

 ence with buildings or with each other. The 

 chapter on Pruning should be read before any 

 attempt at pruning is made. Street trees are 

 too often spoilt by thoughtless "cutting in a 

 bit " by an untrained workman. 



The following lists of trees and shrubs for 

 streets and town gardens have been supplied by 

 Mr. William Goldring. From these lists selec- 

 tions can be made for any town in the British 

 Islands. The more tender kinds are indicated.
