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.), may often be used 

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

 palms (Phoenix and Jubaea).

7. Trees that have been tried in California but have 

 proved unsatisfactory. 



There are many species that have failed to give 

 satisfaction in some localities because of pecu- 

 liarities of climate or soil; there are some, also, that 

 have proved unsatisfactory on account of habit ; from 

 among these may be mentioned : 



Acacia species. Nearly all acacias stump-sprout 

 badly, so that for temporary planting they should 

 be avoided. When planted in narrow parkings, they 

 are very likely to raise sidewalks also, but this can be 

 remedied by frequent root-prunings, which they 

 stand admirably. 



Acacia melanoxylon is generally debarred from the 

 citrus belt as a breeder of scale: when mature it is 

 said to suffer quickly from the effects of drought. 

 In the moister climate of the immediate vicinity of 

 the coast, near San Francisco, however, it proves 

 entirely satisfactory. 



Ailanthus allissima* has a bad reputation on 

 account of its disagreeable odor, but as this is found 

 only in the staminate trees, it can be avoided by 

 planting none but the pistillate (fruit-bearing) trees. 



Cratsegus species. Of all these species, C. Oxyacantha 

 is perhaps the one most commonly used, and through 

 the Santa Clara Valley and Bay regions is disfigured,
