TREATMENT OF CHOLERA 267 



for making same, and if he does, it is better that he should think that 

 you are a bit cranky, if he wants to have it that way, than that your 

 herd should develop cholera. With a more thoroughly widespread 

 knowledge of cholera and the multiple ways by which it may be 

 carried there will be a better appreciation of these dangers and less 

 spreading of the disease by means that could be prevented. 



Addition of New Hogs to the Herd. — We now come to a place 

 where the saddest pages of hog-cholera history have been written. 

 Many and many are the farmers and stock raisers who have gone 

 to great amount of trouble and considerable expense in selecting 

 and purchasing new animals to add to their herds for the purpose of 

 improving their breed, only to find that they have been the means 

 of introducing the dread disease, cholera, with the final wiping out 

 of the entire herd. 



This chapter of hog-cholera history is the more sad when we 

 stop to consider that these fearful losses could have been in large 

 measure prevented had the owner been properly aware of the 

 dangers attendant upon bringing in new swine, and the proper 

 methods of handUng them to prevent spread of any disease with 

 which they might be affected to the balance of his herd. 



Last summer a prominent stock raiser in central Ohio sent 

 over into Pennsylvania and purchased 5 thoroughbred brood 

 sows, which were crated and shipped to his Ohio farm. The ani- 

 mals had only recently been exhibited at a county fair, and had 

 been returned prize winners. Ten days after their arrival at the 

 Ohio farm they began to show evidences of being sick, and within 

 three weeks from the date of their arrival they were all dead and 

 over 50 per cent, of the regular herd were developing unmistakable 

 symptoms of cholera. 



Here we have an excellent example of the dangers of adding 

 newly purchased hogs directly to the home feed lots. If these 

 animals had been kept separate for a few weeks, say, thirty days, it 

 would have been found out that they were developing cholera, and 

 with very Uttle additional precautions the home herd could have 

 been saved from exposure to the disease and the enormous loss 

 which resulted could have been saved. 



This case also presents an interesting problem as to how the 

 infection of these incoming swine took place. It is most likely
