TREES 



20 ft. may be sufficient. As a rule, three small trees to 

 a 50-foot lot will be found ample, and the center one of 

 these three should be taken out when they begin to 

 meet at the sides; if the whole street is planted uni- 

 formly with the same species, and at this same dis- 

 tance, the result will be much more pleasing than if 

 four or five trees are planted in front of every house.

 or with wide spaces between sidewalk and driveway. 



For this purpose almost any of the larger and more 

 Ornamental species enumerated in the other lists may be 

 selected. Spreading coniferous trees, with broad bases 



(such as Sequoia gigantea, etc.) can often be used to 

 advantage, as well as the wide-spreading feather-palma 

 (Phoenix and Jubaea).

7. Trees which have been tried but have proved un- 

 satisfactory . — There are many species which have failed 

 to give satisfaction in some localities because of local 

 peculiarities of climate or soil; there are some, also, 

 which have proven unsatisfactory on account of habit, 

 etc.; from among these may be mentioned: 



Eucalyptus robusta, a species which is exceedingly 

 handsome as a young tree and has been extensively 

 planted along roadsides and streets in the warmer parts 

 of the state; when mature it becomes straggling and 

 exceedingly brittle, breaking up in an unsightly manner. 



Phoenix Ca 

 outdoor planting 



e of the best palms for 

 B.-rkeley, California. 



Eucalyptus corynocalyx also becomes straggling and 

 unsightly with age. 



Schinus Molle should be avoided in the Citrous belt, 

 as it is found to harbor and become a nursery for scale 

 insects. As a street tree it is also unsatisfactory, be- 

 coming too large and straggling and requires too much 

 pruning to keep it within bounds; its large surface 

 roots often break cement and asphalt sidewalks.
