vaccinated upon their arrival; but a large number was shipped from 

 points within the state and were not vaccinated. This was the cause 

 of many new centers of infection in localities that previously had 

 been free. It is unfortunate that the Iowa state laws do not re- 

 quire that all hogs shipped from one point to another within the 

 state must be vaccinated just the same as if they were shipped in 

 from another state. 



If the quarantine and shipping regulations, recommended by the 

 Commission on Uniform Methods for the Control of Hog Cholera 

 at the United States Live Stock Association in December, 1913, were 

 adopted and strictly enforced, the loss could readily be reduced to 

 a minimum. These rules have been published in other periodicals, 

 but I give them again, as I consider them of great importance. 



1. The shipment or movement, interstate, of swine affected with hog 

 cholera to be prohibited. 



2. Exposed swine to be shipped under permit and placarded. 



3. The movement of cholera-Infected swine over the public highways 

 of the state to be prohibited. 



4. Provision for moving exposed swine under permit In approved 

 manner. 



5. Carcasses of animals and particularly of swine that have died 

 of cholera, to be burned within twenty-four hours after death, or under 

 special permit to be disposed of otherwise. 



6. The shipment of swine by rail for purposes other than immediate 

 slaughter to be permitted only through special pens and unloading 

 chutes, or through portable chutes directly into wagons. If unloaded 

 in regular loading pens, to be moved under permit in approved manner. 



7. Public stockyards to be under close supervision and cleaned and 

 disinfected at intervals determined by the proper state authorities. 



8. Railway cars for the transportation of swine, other than such as 

 are intended for Immediate slaughter, to be cleaned, washed and disin- 

 fected before swine are loaded. 



9. All cars in which diseased swine are found, or in which exposed 

 swine were shipped for Immediate slaughter, to be cleaned, washed

 slaughter, as above provided.
