(3) The demonstration, or teaching step, to show people on their 

 own farms that the remedy recommended is adaptable to their con- 

 ditions. 



(4) The selling campaign, to secure adoption of the practice by 

 a majority of the people who should be interested. 



In developing a campaign, use is being made of good publicity to 

 bring before the people the work that is to be done and the methods 

 that will be followed in the campaign ; to enlist the interest and the 

 cooperation of business organizations in order to make easily avail- 

 able the material necessary for the work; and to secure in writing 

 the agreement of the people to carry the work through as worked out 

 by the specialist and the county agent in cooperation with the local 

 people. 



In order to bring the people to a clear understanding of the 

 work and to secure their agreement to carry on their part, meetings 

 are held, and these are usually followed by a house-to-house canvass 

 to get in touch with those not reached through the meetings. A cir- 

 cular letter, finally, is sent to all people in the county who should be 

 interested in the campaign. In this way the extension workers have 

 been able in a number of campaigns to secure adoption of recom- 

 mended practice by from 40 to 60 per cent of those who should be 

 interested in the work in the county. 



FARM FORESTKY. 



Substantial development of methods in farm forestry have been 

 worked out in New York State. There are now a number of farm 

 wood lots under some kind of management and plantations in vari- 

 ous stages of growth, dating back occasionally for nearly 20 years. 

 Tours to some of the more interesting wood lots and plantations 

 serve to develop interest and to stimulate activity on the part of the 

 landowners. 



With this as a beginning, the county agent and the subject-matter 

 leader are able to conduct campaigns through publicity, lectures, 

 and circular letters working toward the establishment of forest- 

 planting demonstrations. In Jefferson County, N. Y., this worked 

 so satisfactorily that the county agent was able to look after the 

 establishment of the plantations without any further personal as- 

 sistance from the specialist than that given at the time of the tour. 



During the spring of 1923 county agents in 39 counties were re- 

 sponsible for over 200 demonstrations, at which a total of over 

 400,000 forest trees were set out. 



PLANT PATHOLOGY. 



During the year very serious consideration was given by State 

 workers to methods of securing general adoption of plant-disease 

 control measures. The number of States maintaining plant-pathol- 

 ogy projects has increased, and from the point of view of methods 

 used in planning, organizing, and teaching certain pieces of work 

 have been conspicuously good. 



In the field of extension methods, especially noteworthy are the 

 building up of spray information services; the development of 

 means for securing wholesale treatment of seed by dealers and by 

 community growers' associations; arrangements for maintaining
