ing growth of the inesquite tree is said to have a marked 

 and beneficial influence upon the climate of the country, 

 inducing more frequent rains and a more nutritious growth 

 of grass under its partial shade. 



One of the most common ornamental trees of the cities 

 and towns of Texas is the Pride of India, or the China 

 Umbrella tree, Melia Azederach, a tree of exquisite sym- 

 metry and appropriate name. The Sapindus marginatus, 

 a native of the surrounding forests called wild china tree,
