TREATMENT OF CHOLERA 237 



feed lots, and it is even better still to make it a rule to keep every- 

 one out of your feed lots, whether they be strangers or not. 



Another outbreak of cholera which was directly traceable to 

 one of these scavenger wagons was reported from southeastern 

 Minnesota. During an outbreak of cholera in that section a few 

 years ago these dead wagons became quite numerous, and, as the 

 outbreak was a very severe one, they found the business a most 

 profitable one. 



One farmer with a large herd of hogs turned them out of the 

 regular feed lots into a meadow pasture which bordered along the 

 public roadway. So far these animals had passed through the 

 outbreak without showing any sign of disease. Cholera was 

 raging, however, all around the farm, and several of these dead 

 wagons were passing by the roadway every day. 



When turned into the new field the hogs at once started out to 

 explore the size of their new territory, and it was not long until 

 some of the smaller pigs crawled through the hedge fence that 

 separated the pasture from the public highway and were out on the 

 roadside. Naturally, they came in contact with infected litter and 

 manure which had fallen out of these scavenger wagons in passing 

 by. 



About the end of the second week after being turned into the 

 meadow pasture the pigs began to show signs of sickness, and in 

 a few days more the old hogs developed a typical outbreak of 

 cholera. The source of the infection here was almost certainly 

 from the infectious material scattered along the public highway 

 by these dead wagons, and which had been taken up by the young 

 pigs. 



This case also illustrates the enormous possibilities for harm 

 that arise from permitting this practice of gathering up dead hogs 

 in these tumble-down wagons, and hauling them along the public 

 highway to scatter infection broadcast over the community through 

 which they may pass. 



Another important lesson to be learned from this man's ex- 

 perience is the danger of allowing hogs to feed in a pasture which 

 borders on a public highway. Public roads are constantly being 

 traveled by wagons carrying hogs to and from markets, and there 

 is always the danger that some of these animals are suffering from
