use and condition of many streets makes successful planting 

 upon them impracticable if not impossible.) 



(2) What kind, type and size of trees can be used with 

 assurance of success under the peculiar, adverse conditions 

 which prevail ? 



(3) What will it cost to do the work on the different 

 classes of streets? (Since the conditions of the streets differ 

 so widely, no uniform system of planting can be used which 

 will be most efficient and economical in all cases. Different

(4) What form of organization will be necessary for se- 

 curing and maintaining satisfactory street tree growth ac-

(5) What is a reasonable budget for the organization and 

 program thus determined upon? 



We will attempt to consider each of these points in order.
