94 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



sands of factory employees and newspaper readers were also reached. 

 Ten thousand posters were distributed and multitudes of people 

 viewed window exhibits. As a result of the campaign a large per 

 cent of the milk surplus was absorbed, milk sales increased, and sales 

 of butter and cottage cheese increased materially. The board of 

 health placed a high value on the campaign as a means of improving 

 the health of the city. Similar campaigns w^ere carried out in IG 

 cities of five States. 



For the rural and small-town campaigns, agents in dairying were 

 appointed for State-wide work in Iowa, Kansas, and Utah. In or- 

 ganizing the work in those States it w^as agreed that the colleges 

 of agriculture were to train dairy workers. The extension depart- 

 ments, home demonstration agents, and in some States the county 

 agents and club agents assisted with the work. The work in Iowa 

 affords an example of how this type of campaign was conducted. 

 In that State the value of milk was brought to the attention of 

 school children by having them write essays on the subject, and 

 4,500 families were reached in this way. In the schools at Ames and 

 Des Moines the value of milk as a food was demonstrated through 

 tests in feeding fixed quantities of milk to a number of abnormal 

 school children for periods ranging from 2 to 3 months. In all cases 

 the results showed th,at milk caused additional gains in weight, and 

 in many cases the children were reported by their teachers to be more 

 alert mentally and easier to handle. In northeastern Iowa an edu- 

 cational campaign was conducted among rural schools and homes 

 and resulted in an awakening among children and parents as to the 

 value of milk as a food. 



Efforts of the women dairy agents and of others who have helped 

 in conducting farm-home dairy work in Southern States have been 

 directed toward greater production of milk and more liberal use of 

 milk and dairy products in the diet. Since a certain amount of milk 

 is usually made into butter on the farm, demonstrations and instruc- 

 tion in improved methods of buttermaking have been given to farm 

 women. The increase in production and use of milk was accom- 

 plished through the " Buy a cow " campaign, instruction in the care 

 and feeding of cows and the proper care of the milk, demonstrations 

 in cooking, buttermaking, and checsemaking, and exhibits of dairy 

 products. 



As a result of this work, 41,000 families are now using more milk 

 for drinking and cooking, 448 family cows have been purchased, and 

 1,042,542 pounds of cottage cheese were made by farm women. An 

 indication of the interest aroused in modern methods of dairying is 

 shown by the purchase of 16,247 pieces of improved dairy equip- 

 ment. Exhibits and contests have also done much to stimulate inter- 

 est in more and better dairy products.
