598 ANNUAL EEPORTS OF DEPARTMENT OF AGEICUL.TURE. 



tions can be more effectively supervised and that a larger number 

 may be conducted by the agent. There has come, too, a tendency on 

 the part of the agents to make the demonstration teaching period 

 more definite. By doing so the number of demonstrations carried on 

 in any one year has been increased and by thus concentrating on 

 single problems a wider adoption of practices may be more quickly 

 secured. Very naturally, too, there has come a wider use of demon- 

 stration meetings, tours, and excursions of people locally to see the 

 results of demonstrations. 



The year has also been marked by an increased use of motion-pic- 

 ture films, charts, posters, project exhibits, and other illustrative 

 material. The use of motion pictures in particular has received 

 greater attention. The results secured in certain campaigns, such as 

 campaigns for purebred sires, control of insect pests, and eradication 

 of tuberculosis, have been very much increased hj the wide use of 

 certain films in connection with such campaigns. 



The old type of campaign is changing and a more effective type 

 is now being given attention by county agricultural agents. This 

 follows the realization that the teaching effort may properly be di- 

 vided, for most people, into three stages; that is, (1) developing 

 interest and attention, (2) awakening confidence and desire, and (3) 

 impelling decision and action. By outlining the plans of work for 

 any project so that the first two are secured through the adequate 

 and well planned use of demonstrations, demonstration meetings, 

 tours, exhibits, illustrative material, trained project leaders, and 

 jDublicity, the demonstration or teaching period may be terminated 

 more quickly and be merged with or followed by a campaign period 

 in which a more intensive use is made of the records and results se- 

 cured in the demonstration and teaching period to induce a definite 

 adoption of practices on the part of a fairly large number of people. 



In such campaigns definite attempts are made to secure pledges 

 from people that they will adopt the practices recommended. 

 Enrollment of such cooperators is secured through personal letters, 

 circular letters, publicity, at subject-matter meetings, or through the 

 efforts of local project leaders. This may be done at the demonstra- 

 tion meeting or at the time that programs for another year are being 

 made up and project leaders and demonstrators give local testimony 

 to the worth of the practices which have been demonstrated. In 

 many ways it seems as if this stage completes a chain which hereto- 

 fore has been broken. 



The programs of supervision are becoming less general and in- 

 clude to an increasing extent the training of county agricultural 

 agents in terms of methods, and particularly in terms of the methods 

 and plans of work needed in each specific case. The problems of 

 securing balanced, unified, workable programs, organizing for ex- 

 tension work, planning for more definite and local use of extension 

 methods, as well as measuring results, are given the very earnest 

 attention of supervisors. In consequence there is more effective 

 local use of extension organizations and the extension service and 

 a larger degree of accomplishment in terms of practices adopted by 

 the people.
