 For years the wheat crop in the great cereal- 

 producing regions of America has steadily de- 

 clined in yield, and, where it has not declined,

 zation has pressed westward, wheat-raising as a 

 chief factor in farm life has been abandoned, 

 until today the vast areas of western Canada 

 are looked to as the last source of wheat supply 

 upon the continent. Even here the virgin soil 

 soon begins to fall away from its huge initial 

 yields. While lack of intelligent farming has 

 had something to do with this, and while the 

 depletion of a once rich soil has been respon- 

 sible for its share of the loss, yet to these alone 

 cannot be given all the blame. 



The wheat is a self-fertilizing plant, preserv-

 But it may change in character, the wheat of
