ELEMENTARY FORESTRY. 



In a row of Elms or other trees there will often be found 

 peculiar individual shapes. Some of the trees will take on 

 desirable forms, while others will be 

 spreading and awkward and perhaps 

 have a tendency to crack in the branches. 

 In some cases a little extra pruning will 

 bring such unfortunates into shape, but 

 often they are incorrigible and are best 

 replaced by other trees with better forms. 

 Protection should always be given street 

 trees as soon as they are set out and this 

 should consist of something that will pro- 

 tect them from sunscald, gnawing of 

 horses, and whittling by thoughtless 

 boys. A good temporary cover is af- 

 forded by wrapping the trunk with gunny 

 sacking or similar material but a more 

 desirable protection is atf'ordod by a 

 slatted wooden frame or hox for each
