6. Trees for Streets, Avenues and Soadsides. — The 

 number of tree species suitable for street planting is 

 limited by the necessarily heavy restrictions, as to 

 height, spread, sewer-penetration and sidewalk-raising, 

 imposed by municipal street departments. In European

Often called Draciena Palm. California, 

 cities the first-named objections are overcome by means 

 of frequent and systematic pruning to a uniform stand- 

 ard; where this necessity can be obviated by tlin selec- 

 tion of trees which naturally keep within iIm- ilisired 

 bounds, the labor of maintaining tbini in :i si^lilly .•ou- 

 dition is minimized and the result murli i,in,-r |il. a>ing. 



For town streets not more than Oil f. ct in widlli, it is 

 important to have trees that will not give too much 

 shade and prevent the rajiid drying of the roadway 

 after showers, nor be so tall nor wide-spreading

It is not wise to use trees of very rapid growth on 

 town streets; they soon become too large and require 

 frequent trimming, which is usually equivalent to muti- 

 lation, and are likely to interfere with sewers. 



It cannot be said that street planting in California 

 towns has, in most cases, been satisfactory. In spite of 

 the much larger variety of suitable material than is 

 available in most of the states, there are few examples 

 of good street-planting to be met with. In most of our 

 towns the eye is greeted with a few straggling trees, of 

 which perhaps not more than two are of one kind, re- 

 calling Professor Waugh's apt simile of "nine mou- 

 ' strously different buttons in a row down the front of a 

 Prince Albert coat." There are many pleasing exceptions, 

 however, although few are entirely satisfactory. The re- 

 peated attempts to iniprove the appearance of a town by 

 planting trees along the streets should be encouraged on 

 every occasion, and the object of this article is to render 



acacias and a few other
