EXERCISE 43 



Object. — To learn to recognize the desirable and un- 

 desirable characteristics of an ear of corn which we wish 

 to use for seed. 



Procedure. — Select and bring to the schoolroom thir- 

 teen ears of corn, each of which is sound and mature and 

 shows vitality. No ear may be considered in this exercise 

 or for seed purposes at any time which shows any evidence 

 of low vitality. 



In addition to the foregoing, each of these ears must 

 show either a desirable or an undesirable characteristic 

 as required below. Those which illustrate desirable charac- 

 teristics are given first and in italics. Note carefully 

 the reasons given for the desirability or the undesirability 

 of the respective ears.
