BUREAU OF ANIMAL INDUSTRY. 93 



Such work has been carried on in many States and has contributed 

 to the marked popularity of the accredited-herd phm. In herds 

 of these associations tested for tuberculosis by the Tuberculosis Erad- 

 ication Division of the bureau, it was found in most cases that only 

 a small per cent of the cows were diseased, but the elimination of 

 the few disease spreaders before the herds could become badly in- 

 fected was of great benefit and undoubtedly prevented later losses. 



DAUiY DEMONSTRATION FARM, DENISON, TEX. 



For several years a dairy farm near Denison, Tex., owned by a 

 group of local businessmen, has been operated as a demonstration of 

 the value of dairying under certain local conditions. This project 

 was terminated during the year by the sale of the property by the 

 owners, there having been a material increase in land values in that 

 region as a result of oil development. During the last year of the 

 project considerable terracing was done and many additions to equip- 

 ment, improvements, and repairs were made from the earnings of the 

 farm. The oat crop yielded well and the alfalfa crop was satisfac- 

 tory, but the corn was only fair, because of dry weather. 



STIMULATING PRODUCTION AND UTILIZATION OF DAIRY PRODUCTS. 



In order to stimulate the production and consumption of milk and 

 milk products for human fcod an educational campaign was carried 

 on in numerous cities and small towns of the Northern States. This 

 w^ork was done principally among women. The objects were (1) to 

 eliminate waste by a more comprehensive and varied utilization of 

 dairy products, (2) to improve and enlarge the food supply, and (3) 

 to encourage the dairy industrj^ The Dairy Division cooperated 

 with the various States through the States ReUitions Service. The 

 campaign w\as divided into two major projects, one dealing with the 

 larger cities in States where a milk surplus was reported, and the 

 other with the smaller towns and rural districts. 



In the city campaigns a wide variety of methods Avas used, de- 

 pending largely on local conditions. In general, however, the process 

 consisted in obtaining a large degree of cooperation from the city 

 authorities, health boards, etc.. together with talks and demonstra- 

 tions in schools, factories, and department stores. In many cases 

 attractive exhibits were placed in store windows and extensive use 

 was made of publicity through press notices or paid advertising. 

 Posters showing the food value of milk were also used effectively. 



An example of such a campaign is the work done in Detroit, Mich., 

 where it was found that there was a 30 per cent surplus of milk dur- 

 ing the spring months. To utilize this surplus and at the same time 

 to increase the consumption of milk and dairy products an extensive 

 campaign was organized. Thirty-five thousand circular letters were 

 sent out to leading citizens, and cooperation was received from 20,000 

 club members, the principals and teachers of the city schools, visiting 

 housekeepers, welfare workers, clergy, physicians, hotels, restaurants, 

 etc. A total of 371 lectures were given in schools, reaching 69,000 

 children directly and their parents indirectly, and the visiting nurses 

 and visiting housekeepers carried the message to thousands of homes. 

 Congregations of G5 churches listened to milk sermons, and thou-
