192 DRY-FAKMING 



The le.sson then to be learned fnjm this chapter 

 is, that it is not sufficient for the dry-farmer to store 

 an abundance of water in the soil and to prevent that 

 water from evaporating directly from the soil ; but the 

 soil must be kept in such a state of high fertility that 

 ])lants are enabled to utilize the stored moisture in 

 the most economical manner. Water storage, the 

 ]5revention of evaporation, anfl the maintenance of 

 soil fertility go hand in hand in the development of 

 a successful sv^tem of farming with(jut irrigation.
