of every community there is nothing that so adds distinction to 

 a town or city as well grown trees along its streets. Whether 

 planted for shade or for ornament, tree lined streets give an air 

 of character and individuality that can be secured in no other 

 way, and not only does street tree planting satisfy merely esthetic 

 ends. It is, if properly done, translatable directly into terms of 

 cash value, for it needs no argument to convince even the most 

 thorough going materialist that a home surrounded by trees and 

 approached through tree lined streets, will, other things being 

 equal, fetch a higher price than a house standing alone in the 

 open. 



The following paper deals with certain of the principles that 

 underlie street tree planting and their application. In general 

 these principles are simple and for the most part the reason for- 

 applying them is self evident. The planting and proper care of 

 trees are not in themselves difficult tasks. Good common sense 

 and perseverance are the most needed requirements. But it is 

 essential that the several steps in the program be systematically 

 and faithfully carried out if real success is to be attained. 



The planting of street trees differs essentially in its purpose 

 from other forms of tree planting. In forest planting, for exam- 

 ple, the object is the production of wood or timber or the protec- 

 tion of a water shed. In orcharding, to make the grove yield the 

 most and the best fruit, while along the street the object of the 

 planting is to add to the attractiveness of the street by securing 

 shade or by adorning it with trees beautiful in color or in form. 



To be adapted for street planting a tree must have a fairly erect 

 habit, or at least be amenable to being brought into shape through 

 pruning. It must be hardy enough to stand more or less neglect, 

 and it should be of a species that is not continually dropping its 

 leaves, twigs or fruit. Further, and especially here in Honolulu, 

 where within an incredibly short distance natural conditions are 

 decidedly unlike, it is essential that the tree be adapted to the soil 

 and local climate of the immediate locality where it is to be 

 planted. 



But before coming to the choice of species there arc other con- 

 siderations that have first to be taken into account. Street tree 

 planting is essentially a matter of cooperation. The first step is 

 to work out a general plan, which, when adopted, shall have be- 

 hind it interest and support sufficient to see it through. It is 

 obvious that on certain streets trees would be out of place ; that on 

 others the requirements are already met by vegetation now grow- 

 ing along the way, within private grounds. Other things being 

 equal street tree ])lanting should begin on residential streets, and, 

 again obviously, it is better to do a little well than to attempt so 

 elaborate a program that the whole thing falls of its own weight. 



Practically all the aullioritics are agreed that in street tree plant- 

 ing the best results both as to effect and as to management are
