24 TOWN PLANTING 



guards there are many kinds : they are made 

 of wood, wire, or iron. The iron tree-guard 

 has many advantages over those of wood or 

 expanded metal, and, being made in two 

 sections, it can be readily placed in position 

 after the tree has been planted. For trees 

 from i 2 to 14 ft. high the guards need not 

 exceed, say, 7 ft. in height, and preference 

 should be given to those in which the up- 

 rights are bent outwards at the top; for this 

 not only lessens the risk of interference with 

 the branches, but is pleasing in appearance. 

 Sometimes it may not be considered neces- 

 sary to protect town trees, particularly such 

 as are growing in side streets, or squares, 

 but in every case firm staking is necessary 

 in order to prevent damage from wind. 



Wooden tree guards consist of about half- 

 a-dozen poles or uprights, about 7 ft. long, 

 joined together around the tree trunk by 

 means of wire. When compared with those of 

 iron, they have, however, several disadvan- 

 tages; for they may be climbed with ease 

 and they do not last long. Where it is found
