the ditch bank. When such trees are grown in plantations, 

 the quantity of water applied and the manner of appli-

 water may be applied, since the main purpose is to produce 

 the largest possible wood growth. 



Practically every tree, shrub and flower known to man, 

 which can endure the soil and climatic conditions of the 

 irrigated area, may be grown under irrigation. Irri- 

 gation is nothing more than supplementary rainfall. 

 Wherever rainfall is desirable for plants, irrigation is 

 desirable also.
