few recovered, wMle the rest of the herd died. Serum 

 is used and recommended as a preventative only, while 

 if used in the early stages of the disease recovery fre- 

 quently results. Of the 156,083 hogs vaccinated, 121,463 

 lived, and 12,090 died. That only 9.12% died,most of which 

 were found in diseased herds, is sufficient proof that 

 the serum will protect. Little progress can be made in 

 the control of any contagious or infectious disease with- 

 out the co-operation of the owners of live stock along 

 sanitary lines. Hog pens and hog houses should be kept 

 clean and should be frequently disinfected; clean beds, 

 clean troughs, and clean water should be provided. In 

 1914, the Bureau of Animal Industry of the United 

 States Department of Agriculture selected one county 

 in twelve states for the purpose of proving whether or 

 not hog cholera could be eradicated from a given area. 

 Henderson county was selected in Kentucky, and con- 

 siderable progress has been made in this work, and the 

 following figures will show that good results may be ob- 

 tained : 



Number of hogs raised in Henderson County in 1912 35,814 



Number of hogs died in Henderson Coainty in 1912 8,743 



Number of hogs raised in Henderson County in 1913 30,866 



Number of hogs died in Henderson County in 1913 3,934 



Number of hogs raised in Henderson County in 1914 20,000 



Number of hogs died in Henderson Coim.ty in 1914 3,902 



Number of hogs raised in Henderson County in 1915 20,000 



Number of hogs died in Henderson County in 1915 1,974 



The use of serum alone has undoubtedly saved the 

 lives of at least 1,118 hogs in one year, and in view of the 

 fact that serum was used in infected herds only and large 

 numbers of already sick animals were treated, the re- 

 sults obtained are very satisfactory. Equally as good 

 results can be obtained on any farm if the proper meas- 

 ures are adopted. 



Glanders, 



This is one of the most dangerous, as well as the 

 most loathsome, disease with which we have to contend. 

 It is particularly dangerous because it is transmissible 

 to man and is just as fatal in man as in the animal.
