stage of the grain. At this stage the plants contain a large 

 amount of moisture, therefore especial attention must be 

 paid to thorough curing in the shock. 



The general procedure for harvesting and threshing oats 

 is the same as for wheat. 



BARLEY 



Although barley may be grown in a wider range of climate 

 than any other cereal, it is produced extensively in five 



states only: Cali- 

 fornia, Minnesota, 

 North Dakota, South 

 Dakota and Wiscon- 

 sin. The reason for 

 this restricted pro- 

 duction is largely an 

 economic one. In the 

 Corn Belt barley can- 

 not compete with corn, 

 but in states farther 

 north where the grow- 

 ing season is too 

 short for large corn 

 production, it may do 

 so. In California, 

 barley is substituted 

 for corn and oats be- 

 cause the two latter 

 do not thrive there. 



The varieties of barley differ in several ways: the heads 

 may have two, four, or six rows of grain and may be bearded 

 or beardless; the hull may be present or absent; they may

 seed that was treated with cresol. (Formal- 

 dehyde would have done as well.) Plants 

 on the right were from untreated seed. (U.S.
