50 Missouri Agricultural Report. 



With the above results before you, I would recommend a 

 quarantine against Kansas City for the protection of the rest of 

 the State should the disease-spreading fountains again be in- 

 stalled. St. Louis unquestionably has many cases of glanders 

 that are not reported to this department. This is perhaps due 

 to the carelessness or indifference of the practicing veterinarians 

 of St. Louis. As soon as funds are available or can be spared 

 from other important work, St. Louis should receive attention. 

 A strict sanitary law on our statute Books requiring the veteri- 

 nary inspection of all horses imported into this State, we believe, 

 would entirely eradicate glanders from Missouri, and within 

 the short space of ten years it would be practically unknown. 



HOG CHOLERA. 



Hog cholera is again prevalent over the entire State. How- 

 ever, we do not believe it will ever become as widespread as it 

 was during 1912, for the following reasons: First, the adminis- 

 tration of the double or simultaneous method immunizes hogs, 

 it is believed, for life. The above method is becoming more 

 and more popular each day, and the farsighted farmer and hog 

 raiser will use this method to the exclusion of the single or serum 

 alone method. The results secured by the simultaneous method 

 warrant its continued use in the eradication of this very impor- 

 tant disease. The fact that the serum alone method creates 

 an immunity of from three to six weeks makes constant revac- 

 cination necessary in order to secure protection on account of 

 the period of immunity being so short and the danger of rein- 

 fection so great. 



We again wish to direct your attention to the second recom- 

 mendation in our last annual report when we urged that all 

 plants engaged in the manufacture of hog cholera serum doing 

 an interstate business be placed under the supervision of the 

 Bureau of Animal Industry. This has been accomplished, but 

 unfortunately the State failed to enact a law providing for the 

 state supervision of plants distributing serum in this State. 

 This is certainly unfortunate for hog producers, as no plant 

 should be permitted to operate in this State that is unable or 

 unwilling to comply with the government requirements. The 

 section governing the disposition of the carcasses of hogs that 

 have died of contagious diseases was changed. They must now 

 be burned or buried under the directions of the State Veteri- 

 narian. Unfortunately, the duty of enforcing this amendment
