SEVENTH ANNUAL YEAR BOOK-PART VI. 235 



practically had hog cholera. These germs that enter are weakened germs 

 and they produce a gradual immunity, but they carry these germs with 

 them and have what we call chronic hog cholera. When you vaccinate it 

 is all right for the bunch you vaccinate, but it is not all right for the hogs 

 you bring in. They may stay around the hog lot, and as soon as you get 

 the vaccination it is all right for you, but if you have a neighbor that 

 wants a brood sow and you ship it out to him, his hogs will get hog cholera 

 and he will wonder where he got it. He got it from that vaccinated hog. 

 Another thing, ycu have a lot of hogs left from an attack of hog cholera. 

 You have perhaps ten, fifteen or twenty from a bunch of a hundred. They 

 are immune. They will never have it again, but they will have ulcers in 

 the intestines that range in size from the size of a dime to fifty cents, 

 and sometimes as large as a dollar. These take a long time to heal, and 

 while they are going through the healing process there is more or less 

 dead tissue, and you have hog cholera as long as you have any hogs from 

 that old bunch. It exposes the hogs that you buy to infection. The best 

 thing to do with that kind of hogs is to get rid of them. Send them to 

 market. Break up your ground, disinfect, and get in a new trough for the 

 hogs. Some of the hogs will get well. I have known hogs to be shipped 

 across three or four States. The older hogs will resist this infection for 

 a long time, and they may have it in a mild form, but that does not hinder 

 them from having chronic lesions. The other hogs, being exposed, have 

 hog cholera from the infection within two days — from two to thirty. We 

 usually say from seven to fourteen days we get hog cholera or swine 

 plague. The only way to combat those thing is go get some laws, and the 

 way for you to get laws is to get legislation. Get interested in politics 

 when you want to get laws, and have the legislator not only promise but 

 see that he does it. If he don't, turn him out and get some other fellow. 

 And then have the laws enforced. The man that owns the creamery 

 won't do it. It will take time. If it is not brought to his mind he will 

 forget about it, or he may not know about it, though the law does not 

 excuse him for his ignorance. There is a law regarding the Importation 

 and inspection of breeding cattle, but of course there is a weak spot in 

 that. I presume the reason it was not made stronger was because they 

 thought it might interfere with the entrance of cattle from other States. 

 I am told that there are men in certain cities that permit the hauling of 

 dead carcasses along the roads. If you do not prevent that and your hogs 

 die no one is to blame but j'ourself. Then there are hogs lying around the 

 farm. It is net an easy thing to do to tell a neighbor to do that, or this, 

 or another thing. He may tell you to do something. But is a thing that 

 should be done to protect yourself against hog cholera ad tuberculosis. If 

 you will get State laws as good as some states have them, then we can 

 build up and add to. For Iowa to be as great a live stock State as she 

 is and be as far backward as she is in these laws, I am sorry to see it. 

 If you want these things get after the newspaper men and have them 

 help you.
