132 ANNUAL EEPORTS OF DEPARTMENT OF AGEICULTUEE. 



DEMON STEATIONAL AND EDUCATIONAL WOBK AGAINST HOG CHOLEBA. 



The demonstrational and educational work, with the object of en- 

 listing the aid of the farmers in combating hog cholera, is conducted 

 in cooperation with the State colleges, each State being regarded as 

 a unit. The plan has been for the department to work through and 

 with existing agencies in the State rather than with individual farm- 

 ers. This work was begun in 1914 in 17 States, as follows : Alabama, 

 Arkansas, California, Florida, Georgia, Indiana, Iowa, Kansas, 

 Louisiana, Massachusetts, Nebraska, North Carolina, Oklahoma, 

 Oregon, Texas, Virginia, and Wisconsin. The outbreak of foot-and- 

 mouth disease in the fall of 1914 made it necessary to withdraw men 

 from this educational w^ork and to discontinue it in Indiana, lowa^ 

 Kansas, Louisiana, Massachusetts, Nebraska, Oregon, and Wisconsin. 



The work of the inspectors may be summarized as follows: Ad- 

 dresses numbering 1,505 were made at meetings, and 378 were illus- 

 trated by stereopticon views. The total attendance was 100,000. Six 

 hundred and sixty-two demonstrations of preventive treatment were 

 made, 394 with the use of serum alone and 268 with simultaneous 

 inoculation. The total attendance at these demonstrations was 20,061. 

 Thirty-two demonstrations of ridding premises of infection were 

 made, and 414 farmers were reached in that way. One thousand and 

 seventy-seven visits were made to farms for the purpose of diagno- 

 sing hog cholera or observing conditions and giving advice, and 7,085 

 farmers and hog raisers were personally interviewed. Individual 

 instruction in properly administering the serum preventive treatment 

 was given to 1,093 people, including 339 county agents, 70 practicing 

 veterinarians, and 684 hog owners. 



State colleges generally report that this work has been productive 

 of a great amount of good. It undoubtedly provides a splendid 

 foundation for future efforts toward eradication or control. 



ENFORCEMENT OF THE VIRUS-SERUM-TOXIN ACT OF 1913. 



The work relating to the enforcement of the act of 1913 governing 

 the preparation and importation of viruses, serums, toxins, etc., for 

 the treatment of domestic animals is divided between the Patholog- 

 ical and Biochemic Divisions of the bureau. The work of the former 

 division has already been stated, but for convenience the entire work 

 will be summarized here. 



Licenses for the manufacture for interstate trade and permits for 

 the importation of such products are issued for calendar years. 

 From July 1 to December 31, 1914, licenses were issued to 40 plants, 

 and from January 1 to June 30, 1915, to 102 plants, some of the latter 

 licenses being reissues of the former. The total number of licenses 

 issued during the fiscal year, including such reissues, was therefore 

 142. Two permits for importation were issued. The 102 licensed 

 plants are located in 48 cities in 17 States. Two hearings were held 

 as provided by law. Information was furnished to the solicitor for 

 13 successful prosecutions for violations of the law. 



Eighty of the 102 plants licensed at the close of the fiscal year 

 were licensed to manufacture anti-hog-cholera serum- and hog-cholera
