Practical Exercises 

 1. Scoring Seed Corn 



Copy the foregoing score card in your permanent note- 

 book. Select ten ears of corn, keeping the idea of 

 "mates" in mind. The ears should look as much alike in 

 every way as it is possible to find them. Find ears all 

 the same length, the same circumference, the grains the 

 same size and shape, without any indications of mix- 

 ture, the rows running straight from tip to butt, and 

 measuring up to the standard of the score card as much 

 as possible. 



Grade each ear of corn on each of the points, and 

 put down on the score card your estimate of how the 

 ear measures up to the perfect grade. It is not ex- 

 pected that you will become expert in one lesson, but 

 you will enjoy the improvement you make in this work. 



2. Selecting Seed Ears 



Using the ear of corn which you have graded the high- 

 est on your score card as a model, look over your entire 

 lot of seed corn, and select one hundred ears which ac- 

 cording to your judgment most closely resemble this 

 sample ear. Number all these ears from 1 to 100, by 

 tying to each a numbered tag, or by sticking a numbered
