 wheat and barley as grown on partly reclaimed land at the 

 Tulare substation. 



While it is certainly true that when rightly treated, alkali 

 lands can be rendered profusely and lastingly productive, yet 

 close attention and constant vigilance are needed so long as the 

 salts remain in the soil; and no one not determined to give 

 such land such full attention, should undertake to cultivate it.
