 the longevity of the tree. The dosire for immediate effect often overthrows 



proper discretion. i^ost of the trees which will give quick results, for example, 

 ths umbrella tree, the Carolina poplar, the silver maple, Acacia pycnantha, 

 Acacia retinoides and many more, do not give p rmanent or lasting results and 

 the effort spent on them is quite wasted* Then, when they have reached maturity 

 and fallen into decay more money and time will be required for their removal 

 and replanting with proper species. Altogether it is more profitable to plant 

 well in the first place than to resort to a makeshift. 



Of course there are no species showing all these points but some are better 

 than others and in certain localities some of these features may not be of much 

 importance. But these should be points of consideration in the study of the 

 local problem. And it is the local Broblea above all things which must deter- 

 mine tlie solution agreed upon.
