TREATMENT OF CHOLERA 245 



the disease to healthy animals. A flock of buzzards circUng over 

 your farm are as dangerous to your hogs as a fleet of bomb-laden 

 airships would be hovering over a fleet of war- vessels in time of 

 war. The bombs which these birds hberate from their claws, in 

 the form of pieces of diseased dead meat, are just as deadly and 

 death dealing to your herd of hogs as are the dynamite bombs which 

 might be thrown down upon the decks of the battleship by the 

 airmen in time of war. 



As an example of the effects which follow a proper disposal of 

 dead carcasses I would like to call attention to the following small 

 outbreak of cholera in central Indiana a few years ago, which was 

 effectually checked without getting off of the first farm on which 

 it started. 



The disease first made its appearance on a small farm of about 

 eighty acres, located in the southeast quarter of the section. 

 This farmer had about 60 head of hogs in all, and the disease was 

 brought on the farm most probably through a boar which had been 

 bought several weeks before. This boar had been through an out- 

 break of cholera, and while he had had the disease in a very severe 

 form he had apparently entirely recovered. 



As soon as this outbreak started the owner notified all his 

 neighbors of the fact and advised them to keep away from his 

 premises. The healthy hogs which were fit for the market were at 

 once shipped. Those which remained rapidly contracted the dis- 

 ease, which, while at first mild, rapidly took on a most deadly form. 

 At the end of three weeks only 3 animals were left alive on the 

 premises. 



Every dead animal was burned the same day on which it died, 

 and the premises were sprayed with a germ-killing dip solution 

 every morning. This man kept his neighbors away from his hog 

 lots and he stayed away from theirs. Many of the owners on 

 surrounding farms had their herds vaccinated, some using the 

 simultaneous, others the single serum, treatment method. 



Not a single buzzard was seen in the locality during the course 

 of the outbreak, and the disease did not make its appearance on 

 any farm outside of the one first infected. 



This is an excellent example of what can be accomplished by 

 proper regard to the laws of hygiene in handling an outbreak of
