SOME INTERESTING FIGUEES SHOWING THE PROGRESS MADE IN THE FIGHT TO RID 

 IOWA OF HOG CHOLERA. 



FROM GREATER IOWA. 



Find the answer in the two maps presented. No. 1 shows the num- 

 ber of hogs lost by cholera in Iowa in 1913, each dot representing 1,000 

 hogs. No. 2 shows the number lost by cholera in 1916, after three 

 years of earnest effort and team work between the veterinary authorities 

 and swine owners. Where less than 500 head were lost the county is 

 left blank. It will be noticed that in map No. 1, showing losses in 

 1913, there is but one blank, Davis county, where the loss was slight 

 for that year, totalling 280. In the other ninety-eight counties the 

 mortality ranged from 993 in Allamakee county to 123,109 in Sioux 

 county. 



In map No. 2, showing conditions in 1916, there are twenty blanks. 

 One of them, Cerro Gordo, has not yet reported, but nineteen of them 

 are blank because the loss from cholera last year was less than 500 

 head. Buchanan county's record is little short of marvelous and indi- 

 cates strict attention to business on the part of swine owners in the 

 fight to eradicate cholera, only five head dying from cholera last year 

 against more than 22,000 in- 1913. 



Allamakee county reports a loss of but seventeen head out of a tidy 

 drove of 64,366 animals. Monroe county lost 33 head out of a total 

 of 29,450. Howard county reports a loss of 60 out of 50,921 head. Davis 

 county owned 44,954 head last year and lost 66 of them. Chickasaw 

 county makes an e.xcellent showing with a loss of 111 head out of 

 136,947.
