ANNUAL EEPOETS OF DEPARTMENT OF AGEICULTUEE. 



A study of the number of outbreaks reported in Dallas County, 

 Iowa, Montgomery County, Ind., and Pettis County, Mo., by months, 

 shows that in these three counties hog cholera was vastly more 

 prevalent in the fall than at any other season of the year. It is 

 recognized, however, that the season of greatest prevalence may vary 

 in widely separated sections of the country. 



The following table gives comparative statistics of hogs raised 

 and hogs that died of hog cholera in 16 counties during the years 

 1912, 1913, and 1914, and shows a marked decline in the death rate 

 from hog cholera as the experimental work progressed. The entire 

 16 counties lost 134,820 fewer hogs in 1914 than in 1913. Particular 

 attention is directed to Montgomery County, Ind., Dallas County, 

 Iowa, and Pettis County, Mo., where the work has been in progress 

 longest and in which the increase in the number of hogs raised and 

 the decrease in the number that died are especially significant.
