EXERCISE XXIII. 

 CORN SCORING. 



Supplies for a Laboratory Section of Twelve. Twelve judging boards as illustrated in Fig. 50. Twelve ten- 

 ear exhibits of corn — preferably exhibits selected from corn grown in your own locality. 



INTRODUCTION. The purpose of the score card is to call attention to points which 

 must be considered in any intelligent judging. It also attempts to set a valuation upon these 

 points roughly proportionate to their importance. Score cards are used by beginners in 

 judging, whether the work be with grain, fruit, or animals. Since the score card is an 

 imperfect device at best, it will be well to discontinue its use as soon as you have thor- 

 oughly learned what to look for and have had some practice in the method of procedure. The 

 use of a score card gives results approaching accuracy only when the material is at least 

 fairly normal in quality. 



DIRECTIONS. Read carefully the explanation of the score card and at the same time 

 make a casual study of the exhibit of ten ears which lies before you. After you have done 

 this, proceed with a more detailed study, as indicated by the following: 



(a) Arrange the ears of your exhibit to show a scale in shape. 



(b) After the instructor approves your arrangement in shapes, rearrange the ears to 

 show a scale in size of shank-scars. 



(c) A scale according to enlargement of butts. 



(d) A scale based on exposure of cob at tip. 



(e) A scale based on the roughness of the ear. 



(f) A scale based on uniformity of kernels throughout length of ear. 



(g) Arrange the ears in such an order as will cause the exhibit to appear as uniform 

 as possible. 



(h) Remove two kernels from one row in each ear between three and four inches from 

 the butt. Place the kernels at the butt of the ear from which they are removed. 



(i) Score your exhibit of ten ears according to the following score card. (Read care- 

 fully what is said concerning cuts and disqualifications in the explanation of the score card.) 



(j) Score other exhibits as they are assigned to you by the instructor.
