STREET TIJEES. 17 



Location. Where pavements are narrow the trees must be 

 placed close to the curb in order that their crowns may have 

 room in front of the buildings. They will be crowded at 

 best. Where space permits it is best to plant Don't plant 



i ^ c mi i close to 



inside the lootway. Inere the trees are less curb. 

 subject to injury and shade the sidewalk and the houses rather 

 than the road. See Fig. 14. 



Footing or Growing Space. As explained on page 24, 

 every me p] anted should have at least 6 square feet of open 

 earth above its roots. If the sidewalks and roadway are 

 paved with concrete this is even more important than where 

 bricks, or other jointed materials are used. On GIve a tree 

 narrow sidewalks the space may have to be room - 

 limited to 1*4 feet by 4 feet, but with that as a minimum 

 strive for openings 3x8 feet, or better still, a continuous park- 

 ing. Figs. 8, 14, 26, Plates I, II. 



THE TREE. 



Be sure to get healthy, well shaped trees. It is a waste of 

 money and time to set the poor deformed things that nursery- 

 men sometimes supply. Wild trees can be used, but they are 

 less apt to withstand the shock of moving than those that 

 have been transplanted once or twice. Don't seek cheap 

 trees ; get them from a responsible nurseryman. 



It is often possible to set out trees as much as 12 

 inches in diameter, but the cost increases much more rapidly 

 than the size. As a rule the stems of the trees should be be- 

 tween 2 inches and 3 inches in diameter, and about 12 feet 

 tall. This serves pretty well the common desire for early 

 results at a reasonable cost. 



Roots. Move a tree with as many roots as possible. It 

 may grow if only the stubs of the main roots are saved ; it will 

 do much better if the whole root work within a radius of 2 

 feet is taken ; give especial care to the finer spare the 

 rootlets, they are the ones that do the feeding. roots - 

 Xever let them get dry ; a dry root is dead !
