LESSONS ON CORN. 3 



given for a perfect ear, e. g., if the pupil thinks ear No. 4 is nearly 

 perfect in shape he would probably mark 9 in line 2, column 4, as 

 shown in the table. Each pupil should examine carefully each ear 

 of corn and put down on his score card, in the column of the same 

 number as the ear of corn, his estimate of the qualities named on each 

 line at the left, except line 4 — vitality — which should not be filled in 

 until after the seed is tested by the method explained on page 4. 



Then compute the germinating value of the different samples on 

 the basis of 20 for a perfect ear, as shown in the score card, and give 

 each ear its proper rating in line 4 of the score card. Now add up 

 the different columns of figures in the score card, and by means of 

 the totals select the best five ears.

In order to understand the meaning of all the points listed in this 

 score card it is well to write to the State agricultural college or 

 to the State corn breeders' association, if there is one, for an expla- 

 nation of the official score card used in your State ; or it may be pos- 

 sible to get some one from the agricultural college or other agricul- 

 tural school to come to your school or county teachers' meeting and 

 explain the score card fully.
