its refinement as a well planned and well executed planting of trees along its 

 streets. Above all things else, let the plan ba good. 



The logical outcome of any plan, of any good plan, is unity. Do not 

 imagine that uniformity means the restriction to a single tree, so that wherever 

 one would look that tree would dominate the landscape. Such a proceeding would 

 violate the much abused and yet often neglected principle of variety. But the 

 concensus of opinion demands that the uniform work should be strictly adhered to 

 for each street in towns and cities. In the country more latitude is permissible. 

 (There are some valid arguments against this, of which more hereafter). The 

 desirability of this, is most evident when one considers the results now seen. 

 In a certain city, where up to the present time all planting has been at the 

 discretion or better notion of the property holders, some queer combinations arise. 

 For example, the east side of one block shows, - one chamaerops, one oleander, one 

 chamaerops, six white elms, six liriodendrons, one vacant lot, two umbrella trees, 

 four silver irwples r a Canary Island date palm and a walnut I Across from this 

 mixture tnere are but twelve trees, - two umbrellas, four chamaerops palms and six 

 elms. Another characteristic lot runs like this : four grevilleas, two walnuts, 

 six lindens, vacant lot, two big leaf maples and four lindens. While across the 

 street are two silver maples, two horse chestnuts, two elms, six blank, four haw- 

 thornes and two elms. Imagine, if you can, any symmetry or satisfaction in this 

 young nursery. Here we have a variety with a Vengeance, but no trace of Unity 

 or Coherence. 



If we were to analyze the conditions on that block, we should find that there 

 we have the following state of affairs:- 



1. One evergreen against six deciduous species. 



2. Four unplanted lots, offering at least four chances for new species 

 and time of planting. 



3. Two short lived species against five medium and long. 



4. One globular dwarf; four modiuin globular; one even-shaped; and two 

 straggling.
