Illustrative material. Secure and label specimens of the different 

 races and varieties of corn. Secure from farm papers and catalogues 

 pictures of races and varieties of corn, plows, corn planters, cultivators, 

 and harvesting machinery. See illustrations in the bulletin. 



Practical exercises. (1) Selecting in the field, gathering, storing, 

 judging, and testing corn. Mixing fertilizers and studying farm machin- 

 ery afford suitable practicums. (2) Corn-club members get profitable 

 home work in growing an acre of corn. 



Correlations. Language : Require the members of the class to write 

 accounts of field trips for seed selection, descriptions of sand tray and 

 rag-doll testers, and descriptions of farm machinery. List and spell all 

 new words appearing in these studies. 



Drawing : Make drawings of the different seed testers used and proper 

 and ill-shaped grains. 



Geography : Locate on the map the 10 leading corn-producing States. 

 Compare them as to location, climate, and other agricultural industries. 

 In what other countries is corn grown ? Compare these countries with 

 the corn-growing States as to longitude, latitude, climate, and other agri- 

 cultural industries. What part of the corn crop of the United States is 

 exported ? What countries constitute our corn markets ? What is the
