SEVENTEENTH ANNUAL YEAR BOOK— PART IX 505 



13. Infected premises to be quarantined not less than sixty days 

 after last traces of disease have disappeared, and premises have been 

 cleaned and disinfected. 



14. Infected premises to be cleaned and disinfected under supervision 

 prescribed by livestock sanitary authorities. 



15. The live stock sanitary authorities to be given power to provide 

 in a practicable manner against the dangerous pollution of streams 

 with hog-cholera virus, and provide for the safe disposal of garbage 

 liable to be infected with hog-cholera virus. 



16. To prevent the spread of hog cholera by swine shown for exhibi- 

 tion purposes, such swine to be treated with serum and virus not less 

 than twenty-one days prior to the opening date of the exhibit, or with 

 serum alone, not more than fifteen days before such time. 



17. Provision for controlling for thirty days, by quarantine or other- 

 wise, when deemed advisable by the proper authorities, of all swine 

 treated with serum-virus, or premises on which such swine are kept, 

 to prevent danger of possible spread of infection from inoculated animals. 



If we would do nothing more than to pass laws that strictly en- 

 force these rules, passed by this association, we could reduce the loss 

 of hog cholera from millions each year to a very small amount. . 



The question of eradication evolves itself into the willingness of 

 the farmer and stock raiser to co-operate with the State Animal 

 Health Board in passing laws along scientific sanitary lines, but just 

 so long as they continue to fight all laws and regulations laid down 

 by state and federal boards (as has been done in the recent fight 

 against foot and mouth disease here and in our neighboring states), 

 just so long will hog cholera continue to kill millions of dollars' 

 worth of hogs each year. But as soon as all parties interested will 

 be willing to get together and work in unison, just so soon will we 

 be able to entirely eradicate this disease from our country. 



DOURINE. 



Early in October, 1915, the existence of Dourine was suspected in 

 some horses in the southern part of Carroll County. Samples of 

 blood Sera were sent to the Bureau of Animal Industry, U. S. De- 

 partment of Agriculture, at Washington, D. C, and on October 30, 

 1915, this department was notified from Washington that the blood 

 samples gave positive reaction to the compliment fixation test in- 

 dicating the existence of Dourine. 



In co-operation with the Bureau of Animal Industry this depart- 

 ment made investigation, studied the stud books of the community, 

 and tested every stallion, mare and jack that were known to have 

 been exposed to the infection. In addition to this, all stallions and
