THIRTEENTH ANNUAL YEAR BOOK— PART IV 153 



right there; so he will have to bo quarantined too, along with the rest 

 of them. 



Let me say to you that there is a normal cholera season; it cor- 

 responds to the normal typhoid season, beginning in midsummer and 

 running through the fall and on into the winter. In a normal year we 

 might not hear of an outbreak of cholera in April, May or June in the 

 state, but we would look for them in July. Suppose we get notice that Jones, 

 in the center of a certain township in a certain county, has hog cholera. 

 We go there and apply the quarantine to Mr. Jones and to all connected 

 with him, forbidding them to go to any neighbor's hog lots, and for- 

 bidding any neighbor to come to Mr. Jones' hog lots. We find a number 

 of the hogs already sick with cholera, and when they are already sick 

 they are gone, except for the few that may have constitutional stability 

 enough to go through, or may have some degree of natural or acquired 

 immunity to help them through. We take the temperature of the hogs, 

 as fever is one of the first symptoms in hog cholera. Perhaps some 

 have already died, and we inquire what disposition was made of the 

 carcasses. Those that are sick and we think there is no hope for, we 

 w^ould ask Mr. Jones to kill right away, pile them up and burn them, 

 and with them burn all the bedding about the lots and pens; and if 

 the hog lots are good, you can rake and sweep them and burn the 

 Takings and sweepings. Then use the disinfectant, and use the serum on 

 those hogs that you think there is a show to save. If we get there 

 early we might save ninety per cent, in place of losing ninety per cent. 

 As an additional safeguard,, you could go all around Mr. Jones' lot for 

 a mile or two, but you w^ould want to disinfect yourself before you went 

 — your shoes and all your clothing. We have veterinarians now using serum 

 in Iowa so carefully that when they are using the simultaneous method 

 they strip off their jumper suit, and their old rubbers, if they have rub- 

 bers on, and the towels (they buy five-cent towels by the wholesale), and 

 in the presence of the farmer they do the work, for they burn the whole 

 thing, and disinfect every place where possibly they might have dropped 

 any of that virus. That is the proper way to do. We have other veter- 

 inarians traveling over the state with knee boots on that are smeared 

 with cholera blood to the top of them, and they never stop long enough 

 to disinfect the boots. That is not doing it right. 



The Dominion of Canada would kill all of Mr. Jones' hogs and pay 

 him for them. Then they disinfect the premises, and say they are so 

 successful that they haven't thought it necessary to go into the serum 

 business. 



The state of Ohio is supposed to be in the advance of all other states 

 just now in the handling of hog cholera. They have finished a plant in 

 which is invested $125,000. It has an eighty-acre farm with a complete 

 line of laboratories and buildings for serum production. They are using 

 it on every herd under quarantine, and none but the men employed 

 by the state of Ohio are injecting one drop of it, supposedly because 

 they know how to do it without exposure to anybody else. I believe that 

 is the right way to adminster the simultaneous treatment. I could give 

 you instances where the simultaneous treatment was used in a man's
