methods of swine production. The adult demonstrations in connec- 

 tion with poultry were 33,400, with a club completion of 45,000. 

 Dia'ing the year 170,000 persons were thus led to improve their 

 methods of poultry production. The number changing their farm 

 practices with reference to poultry was greater than for any other 

 productive farm enterprise. 



The agents report that in 1922, as a result of their suggestions and 

 advice, 7,800 purebred dairy bulls and 15,000 purebred dairy cows, 

 7,500 purebred beef bulls, 6,700 purebred beef cows, 14,900 purebred 

 boars, 40,750 purebred sows, 3,300 purebred rams, and 6,200 purebred 

 ewes were purchased. The county agents cooperating with the 

 Bureau of Animal Industry continued to take an active interest in 

 the better livestock campaign. The reports indicate that at present 

 there are 8,925 farmers who have enrolled 150,000 head of cattle, 

 105,000 head of sheep, 87,000 head of swine, 18,000 head of horses, or 

 360,000 animals, of which 144,000 are purebred, as well as 720,000 

 head of poultry. 



The spread of the cooperative bull associations has been such 

 that in 1922 there were 190 active associations with a membership of 

 6,100 farmers owning 860 bulls, 7,125 purebred cows, and 33,500 

 other cows. 



The organization of farmers into cow-testing associations in order 

 to secure a more profitable output and to determine which are the 

 more productive animals continues to prove successful. The num- 

 ber of associations increased during 1922 by more than 50 over the 

 previous year. The present records show that there are 513 active 

 associations with an enrollment of 12,510 farmers owning 220,000 

 cows. 



Livestock disseises. — The county agents were very active during 

 the year in attempting to prevent the large losses of livestock from 

 diseases and various kinds of pests. Altogether, 1,520,000 head of 

 cattle were treated for tuberculosis and 440,000 were inoculated for 

 blackleg, and 980,000 hogs treated for cholera. Over 4,000,000 were 

 treated for various livestock diseases either upon the advice of the 

 agent or as a result of previous demonstrations. 



Agricultural economics. — ^Although the work in the field of agri- 

 cultural economics has not been put on a demonstration basis to the 

 same extent as other types of agricultural activities, it has resulted 

 in improving agricultural practices to a marked degree. During 

 1922, 84,000 farmers changed their farm enterprises or improved 

 their livestock and cropping systems, and 940,000 farmers or mem- 

 bers of their families joined marketing organizations or were aided 

 in the disposition of their crops or the purchase of supplies by the 

 extension service, which resulted in a total business of over $260,- 

 000,000, or a saving of nearly $18,000,000 to the farmers. 



SOME RESULTS OF HOME DEMONSTRATION WORK. 



Home demonstration agents concerned themselves as usual in 

 promoting better practices in the various phases of home economics 

 and such additional matters as poultry, dairying, gardening, home 

 beautification, community betterment, marketing, and like matters 

 touching the home or increasing the wife's income.
