winters a deciduous tree is often preferable. Palms are monotonous, and for this 

 and other reasons most unsuitable for long avenues, though for short distances 

 they sometimes make magnificent displays. Slender and spire shaped trees are 

 very ill-adapted for this purpose in warm countries. Nothing can exceed the 

 beauty of a well developed and well kept pepper drive, and this tree, together 

 with camphor, Eucalyptus viminalis and E. corynocalyx, give splendid results in 

 dry, warm countries. There are still others even finer than these which we as yet 

 know but little and which are destined to add much to the beauty and interest of 

 our avenues, as has frequently been indicated by Dr. Franceschi. We are trusting 

 he will describe and illustrate these for us in future numbers of this Journal. 



In the meantime several working principles may be brought sharply to the 

 attention of all property owners of Southern California and other subtropical 

 regions : 



1. Plant now! A month or a year saved now means a matured avenue 

 growth so much the sooner. 



2. Place this work under the strict control of county, town, or park officials, 

 and then urge them to immediate action. Left to the whim of individual property 

 owners, uniformity of plan will certainly be impossible to attain, to the great and 

 long-time detriment of the whole locality. Private individuals should no more be

 years required for full development this short stretch of solid Phoenix will be of 

 great magnificence.
