rarely produce serious effects; it lives to a considerable age and throughout 

 its existence needs but little attention to pruning; it is fairly free from 

 litter and is indifferent to cultural conditions. Here is a tree with a 

 desirable set of qualifications which in almost every case is planted in such a 

 fashion that it becomes vary undesirable. When planting this acacia it should 

 be borne in mind that it is an evergreen of a green black color and of a density 

 of growth which produces a vsry intense and dark shade. Moreover it is a tree 

 which needs abundant room for development. This fact is one which is frequently 

 overlooked since we can find many instances where it is set at intervals of some 

 twenty five or thirty feet so that a solid hedge of trees has developed, com- 

 pletely shutting out the sun from the houses behind them, until about noon. 

 Furthermore, any air that may be in circulation is effectually shut off. The 

 solution of theproblem is easy. If one feels that Acacia raelanoxylon is necessary 

 to his happiness, buy specimens that are headed high; prune out enough branches 

 to keap the head from being too dense and plant at least fifty feet apart, pre- 

 ferably alternating across the street. In the case of very wide streets, this 

 last precaution is, of course, unnecessary. 



The question of litter is no small matter in the appearance of the city. 

 And the tree which is untidy should have no preference over less annoying trees, 

 in tha scheme of civic decoration. A case of a very common malefactor is the 

 ever-popular umbrella tree (Melia asadarach). This tree, which is almost 

 invariably headed too low, causes a litter in the spring at flowering time; in 

 the autumn the leaflets drop; then the petioles, and last of all, - intermittently 

 through tine winter, - the berries and the panicles that bore them. Here we 

 have a case of constant litter for about two-thirds of the year, which certainly 

 outweighs the possible beauty of foliage or flower. Another instance is the 

 grevellia where the litter from falling leaves and broken branches is quite 

 incessant. 



And last, but not least, from the practical and economical standpoint, is
