EXERCISE 24 

 A STUDY OF SHELLED CORN 



Object. To study corn with reference to its quality 

 and commercial grade ; and to become familiar with different 

 classes and grades of corn. 



Explanation. Practically two thirds of the corn crop 

 of the United States is produced in eight states: Illinois, 

 Iowa, Kansas, Nebraska, Missouri, Indiana, Ohio, and 

 Texas. Within these same eight states the live-stock in- 

 dustry has been developed to the greatest extent. While 

 corn is used almost exclusively as a food for live stock, large 

 quantities are sold on the commercial market before reaching 

 final destination. For the proper classification of corn of 

 varying quality it is necessary to have a system of grading. 

 In determining quality it is necessary to consider purity, 

 condition, color, and size of kernels. 



Equipment. 1. Four ten to twelve pound samples of 

 corn representing different grades. 



2. A weight-per-bushel tester. 



3. A balance weighing to a half gram. 



Directions. Weigh out fifty grams of corn from one of 

 the samples, and make a detailed study of it. Use the out- 

 line form " A Study of Shelled Corn " to record the results 

 of the examination. Classify the sample of corn under ob-
