of a heavy and disagreeable odor emitted by the staminate 

 trees, only the pistillate form should be used. These may 

 be readily secured by grafting from proper trees or by 

 growing them from cuttings. The city of Paris uses the 

 Ailanthus freely in street planting. 



Honey Locust. The soft, delicate foliage of the 

 Honey Locust gives this tree an attractiveness which en- 

 titles it to a claim on the 

 interest of tree planters. The 

 foliage is light and open and 

 produces the moderate 

 shade desirable for narrow 

 streets. Its flowers are fra- 

 grant and rich in honey, and 

 the thorns on the branches 

 add to its picturesque effect. 

 The tree is of hardy and 

 fairly rapid growth, and not 

 exacting as to conditions of soil and environment, standing 

 pruning well. It is particularly useful because it thrives 

 in the dry regions of the west. In some sections the 

 thorns are considered an objection, and a'thornless form 

 is sometimes obtainable. 



Pepper Tree. The California Pepper tree is much 

 used in southern California. It is a moderate-sized, 

 broad-headed tree with fine foliage, which gives it a light, 

 airy appearance. During the fall and winter it is covered 

 with scarlet berries which in contrast with the persistent 

 foliage produce a pleasing effect.
