to be had by using a single species within a given unit of street 

 length. Usually, this unit should include several blocks, both sides 

 of the street. Here again is emphasized the necessity for coopera- 

 tion. 



Because of the many details that have to be attended to in tree 

 planting, many of them requiring some technical skill to carry out, 

 far better results will be got if the work is entrusted to some one 

 "body, such as a committee of the local improvement association, 

 rather than if it is left to individuals. In Honolulu we are prone 

 to over-organization. In this matter there is already in existence 

 plenty of machinery. The proper organization to do the active 

 work of street tree planting is the improvement club, backed by 

 the Central Improvement Association, when questions arise that 

 involve territory covered by more than one local club. What is 

 needed now is to bring pressure to bear on the local clubs to have 

 them take up and carry through this class of work. How such in- 

 fluence can best be exerted we need not here discuss, though per- 

 sonally I think that much more would be accomplished by the 

 local improvement clubs, not only in this but in other ways as 

 well, if there were more women members. 



Having decided that a given section of a certain street should 

 he planted with trees, the next step is to determine the location 

 of trees, whether in the "parking" between curb and side walk, 

 or within the boundaries of the lots. Aluch depends on the width 

 of the street, and into the consideration comes, too, the question of 

 where there is likely to be the least interference with the poles and 

 wires of electric companies. We must, of course, recognize that 

 until that happy day comes when all the wires go underground, it 

 is only just that the electric companies have the right to keep 

 their lines clear. But there is a great difference in the way the 

 necessary pruning is done. Some of the foremen exercise care 

 as it is now. Others, unfortunately, do not do so. Under the 

 law the superintendent of public works has the power and author- 

 ity to grant the right to set poles and to plant trees on the streets, 

 and to make regulations governing the same. The question of 

 how this control can be more strictly enforced is now receiving 

 the attention of the Territorial authorities. But so far as possi- 

 ble it would be well to avoid friction by choosing for street plant- 

 ing those species which will keep below the wires, or by so placing 

 the trees that they will not interfere with them. 



Alention has already been made of the desirability in street 

 planting of using trees of upright habit. It is extremely annoy- 

 ing to have low hanging branches extend over the sidewalk, and 

 it is unnecessary, for only those trees should be used that will nat- 

 urally, or that can be made to assume a proper shape. 



Incidentally it may be said that in general the pruning of trees, 

 while not a difificult matter, is one that should receive a larger share 

 of personal attention from the householder than it now does. 

 Every kind of tree has its individual habit. The object of prun-
