noted in a few instances. Here the style of growth is quite different, being 

 dwarfer and giving a low rounded head. 



The Willows. 



Of all the Billows, the old Weeping Willow ( Salix Babylonica) i 8 perhaps the 

 rnoet frequent in use. Owing to the brittle nature of the wood it is hardly 

 suitable. Again, trees of weeping habit, like those of colored or variegated 

 foliage are rather the exception in the vegetable kingdom and their use on streets 

 would be a violation of general principles. 



The Pepper-Tree,. 



The Pepper Tree (jtehinus moll a) is perhaps the most common exotic tree found 

 in Southern California. Everywhere one turns, there is the omnipresent bright 

 green foliage of the pepper. Nevertheless, the Pepper is beginning to fall into 

 disrepute. For one tiling, it is a particularly acceptable host for the Black 

 scflle. TO be sure, if the trees are cut back past all the green wood and the 

 trimmings burned, all the scale insects are destroyed for a time but this means 

 endless work. Fumigation is practically impossible and spraying is not suffi- 

 cently effective to warrant even, its consideration. 



Again, at Riverside, and other towns where the Pepper is freely planted, 

 they are finding that the treo needs constant trimming. The young branches 

 are pendant, often for five feet or more. This of course makes the tree a 

 nuisance to pedestrians. Fur the rmo re , if the tree is cut back to stub, although 

 it reclothes itsslf very promptly, there is usually precipitated a hubbub of in- 

 discriminate popular criticism and it is quite true that the trees are temporarily 

 ruined in appearance. 



Anyone considering the use of the Pepper should remember this: 



1. The pendant habit of young growth means continued pruning. 



2. The Black Scale infests it. 



3. It needs vary wide parkings on account of the irregularity of the 

 trunk and the breaking of pavements.
