when they are grown the old ones removed. 



5; If trees are to be planted in a street where the only 

 available room is already occupied by wires, that is a street 

 with little space between the curbs and building lines, there 

 are just three courses open: one, to induce the electric com- 

 pany to remove the wires before the trees are set; two, to 

 get an agreement that they will be removed or raised at a 

 fixed time in the future, or when the trees shall have grown 



so that tree shoots and wires interfere; three, 

 frees*. *' to plant low growing trees and by pruning keep 



them below the wires. The last is often a good 

 plan, as big trees are out of place in a narrow street.
