No. 6. DEPARTMENT OF AGRICULTLRE. 115 



past aud the fear that the disease will again cause serious depreda- 

 tion if hogs are brought together in huge numbers. At distilleries 

 and creameries, hogs are not extensively fed on account of this dis- 

 ease. If an ell'ective vaccine or antitoxiue were available for the 

 protection of hogs, a great industry would be added to those existing 

 in this State. It was hoped a few years ago tliat the investigators 

 of the Bureau of Animal Industry had discovered a preventive; but 

 later results do not appear to have fully sustained the early hopes. 

 There is, however, reason to believe that such a preventive may be 

 found, aud if so, it will quickly be made available for the use of the 

 hog raisers of Pennsylvania. At present it is necessary to continue 

 to depend on quarantine, separation and disinfection. 



Some outbreaks of fatal contagious disease among hogs are not 

 hog cholera nor swine plague, although resembling these diseases in 

 many respects. Of course an antitoxine or a vaccine effective against 

 hog cholera could not be expected to be effective against this other 

 disease, and so it is important that the contagious diseases of swine 

 shall be studied and more accurately differentiated. This study is 

 now in progress in the laboratory of the State Live Stock Sanitary 

 Board.
