little triangular leaflets come forth on their long leaf-stalks, and glint cheer- 

 fully in the sun, which led the poet Cornwall to say : 



"The poplar there 



Shoots up its spire, and shakes its leaves 

 In the sun." 



Lombardy poplar should never stand alone, but should be placed so that 

 the row of vertical green plumes may form a contrast with some horizontal 

 line such as a railroad embankment, or the arch of a viaduct. 



CHINESE POPLARS 



These poplars (Populus chinensis), (Populus simonii), and (Populus 

 tomentosa), that have recently been introduced from China, give promise of 

 making very satisfactory growth for quick windbreak protection. The first 

 has an upright habit similar to the Lombardy poplar but with more graceful 

 leaves. The second has glossy leaves which are of unusual shape. The third, 

 as its name implies, is distinguished by the silvery tone of its leaves. This 

 tree has made remarkably rapid growth at Berkeley and Chico. 



PRIVETS 



The privets embrace about thirty-five species of small trees and shrubs 

 from Europe, Asia and Australia. They are valuable for their hardiness and 

 are extensively used for formal planting especially for hedges and screens. 



The Japanese privet (Ligustrum japonicum) is a large shrub or small tree 

 with leathery, dark-green leaves and white flowers which have a sickly sweet 

 fragrance. They are followed late in the summer by dark-blue berries. This 

 privet is good for a tall hedge, but also makes a handsome flowering tree. 

 When grown as a tree care should be taken to select specimens from the nur- 

 sery which have unbranched leaders for at least seven or eight feet, since the 

 head is formed very low after branching begins. It needs a wide parking on 

 account of its spreading crown which gives abundant shade at maturity. 

 Constant care is needed to keep down suckers which tend to spoil the shape of 

 the tree.
