The effect Las beeu to greatly reduce the number of outbreaks and also 

 the number of animals slaughtered. For a time the reduction in the 

 number of outbreaks and also of pigs slaughtered was so marked that 

 much hope was entertained that it might be possible to completely con- 

 trol the disease. The very serious restriction to trade and the heavy 

 expense has brought many protests from the producers and the restrictions 

 are again becoming less rigid. It will take more time before a conclusion 

 may be drawn as to the possibilities of this method. 



In 1897 the government undertook an experiment in Page County, 

 Iowa, to determine what might be accomplished by county police 

 measures. The plan was to canvass a part of the county and determine 

 the number of pigs raised the year before, the number that died and the 

 number now on hand. Upon receipt of notice of an outbreak the veterin- 

 arian called and killed all the sick and paid the owner at market rates. 

 Disinfection and general cleaning of the premises followed. It is believed 

 by some that the saving more than paid the expenses. 



Several of the States have laws upon hog cholera, but they usually 

 di'line the manner in which the carcass shall be disposed of. Minnesota 

 probably undertakes more than any other State, and there the matter is 

 in the hands of the State Board of Health. Canada demands a certilicate ^ 

 of a clean bill of health from the State Veterinarian before they can be 

 shipped in. The tendency is toward making transportation companies 

 disinfect cars, yards, etc. 



In our own State the law i*equires burning or burial of the carcass; 

 it requires a certificate of health to exhibit at the fairs and the disinfec- 

 tion of pens, etc., at fairs. It is an imperfect law, but has been the means 

 of saving many thousands of dollars. 



The problem of State control Is .of great importance and will not be 

 settled soon. In the meantime this State should not be content to sacrifice 

 $2,000,000 worth of stock annually without making some effort to deter- 

 mine new facts concerning*this disease. 



Tuberculosis of Hogs.— Tlie abattoir statistics published by the bureau 

 of animal industry show this to be a fairly common disease of swine. 

 Tuberculosis has been increasing among hogs during recent years, but 

 is not nearly as jircvalent here as it is in Euijipean countries. There the 

 disease is more prevalent among cattle, and statistics abroad sliow that 

 the percentage of tubercular hogs increase as the affection becomes more
