EXHIBITS, REWARDS, AND ORGANIZATION FOR CLUBS. 
Since the rural schools have begun to teach agriculture a wide and 
useful field for school exhibits has come into existence. Many 
teachers are using exhibits as the best means of calling the attention 
of their respective communities to the work that is being done in 
agriculture. It is well to hold an exhibit in the schoolhouse at the 
close of the contests and invite parents and others interested in school 
work to attend. Before an exhibit should be allowed to enter a 
contest or school credit given for a home project in cotton, a report 
similar to that given below should be kept and presented in good 
condition with the exhibit. 
For information and suggestions on rewards or prizes as well as 
organization of clubs write your State agricultural college.
