fective use of 30 posters j)ortraying the various activities of the 

 department and " selling " its service to the public. Assistance has 

 been given a number of the bureaus in the preparation of illustrated 

 circulars. 



DISTRIBUTION OF PRESS MATERIAL. 



Ever}' effort is made to give the wisest possible distribution to 

 our press material, so as to place it onlj^ where it will be of interest 

 and to avoid waste. The mailing lists have been so specialized that 

 it is possible to distribute material locally or generally or to pub- 

 lications even in different classes which have a common interest in 

 a subject. To place an agricultural story strictlv within the region 

 of its applicability is sometimes extremely difficult, and in such 

 cases editors are given the. benefit of the doubt, as it seems better to 

 include them in the distribution of a story rather than to miss them 

 altogether, especially since editors many times are likely to be in- 

 terested in the problems of their neighbors. 



The work of the Office of Information was directed by Harlan 

 Smith, assistant in charge. 



PROGRESS IN MOTION PICTURES. 



Marked advances made in the fiscal j^ear 1920 in the production 

 and distribution of the department's motion pictures leave no doubt 

 as to the effectiveness and value of this mode of bringing directly to 

 the people the knowledge developed by the department's investiga- 

 tions and of acquainting the public with the methods and significance 

 of important lines of work being carried on by the department. 

 These forward steps may be described as follows: 

 Editorial and laboratory work was completed on 52 new motion- 

 picture subjects, and they were added to the department's film 

 library. The largest previous number of releases in a single fiscal 

 year was 18, in the fiscal year 1919. A list of the new subjects 

 follows :
