DISCUSSION PAPER 



A supplement called the discussion paper is sent with each Reading- 

 Course lesson, for the purpose of bringing out the main points covered 

 and of calling attention to related agricultural facts, practices, or methods. 

 The College encourages an expression of opinion or a statement of experi- 

 ence by means of the questions asked. Each discussion paper filled out 

 and returned will be read carefully and a personal reply will be made if 

 agricultural information is desired regarding personal or community 

 problems or the subjects studied. 



New readers should enroll in one or more of the following series of 

 Reading-Course lessons: the soil, poultry, rural engineering, farm 



FORESTRY, THE HORSE, DAIRYING, FRL'IT-GROWING, FARM CROPS, STOCK- 

 FEEDING, VEGETABLE GARDENING, PLANT-BREEDING, COUNTRY LIFE. The 



first lesson in each series desired is sent on enrollment, and subsequent 

 lessons are sent, one at a time, on the return of discussion papers. There- 

 fore, in order to receive the other lessons in this series, readers should sign 

 and return this discussion paper, whether the questions are answered or not. 

 As an aid to students taking Reading-Courses, study clubs may be formed 

 in various localities. References for advanced reading will be given 

 on request. The space below on this page is reserved for correspondence 

 concerning Reading-Course work, and also for names and addresses of any 

 persons likely to become interested on receipt of information.
