head of registered Berkshires that I bought and shipped in since 

 the outbreak last June. My experience has been that if treated 

 before being exposed to the disease hogs may then be exposed 

 to any amount of cholera and not over 5^ will die. I may be over- 

 enthusiastic about the value of the "hog cholera serum" you are 

 preparing, but arter losing over eighty head with cholera in less 

 than thirty days, and then finding a remedy that has since saved 

 me ^bfo of all animals treated, either aged hogs or little suckling 

 pigs, I feel justified in being enthusiastic." 



Mr. G. E. Leslie of Memphis, Scotland County, Missouri, Di- 

 rector of the American Poland-China Record, and owner and 

 breeder of some of the most valuable animals of this breed in 

 America, lost a part of his show herd last year at the close of the 

 fair season. The others were saved by inoculation. That part of 

 his home herd that was in greatest danger of becoming infected, 

 was also inoculated with "protective serum." Only one of these 

 became ill and died, whether from cholera, was not definitely de- 

 termined. Every possible effort, however, was made to keep the 

 infection away from the main herd by strict isolation of the dis- 

 eased animals and thorough disinfection. The disease was stamped 

 out without the spread of the infection to any of the surrounding 

 farms. Mr. Leslie wrote: "I wish to thank you and assure you 

 I appreciate what you have done for me." 



Mr. Hugh Whiteford of Nodaway county, breeder of Poland 

 China hogs, reported a month after inoculation, as follows : "Two 

 of my old sows and several pigs, which were sick tvhen inoculated, 

 have died, but those that were well at the time of inoculation are 

 still all right." These hogs all ran together on the same grounds. 



Mr. Medsker of the same neighborhood reported two months 

 later in regard to his herd : "The cholera was in my herd of hogs 

 and I had lost fifty or more, when you came and vaccinated those 

 not infected. Not one of the vaccinated hogs has died. I believe 

 the serum a wonderful discovery, and wish you abundant success." 



Mr. A. L. Perrin of Buckner, Jackson county. Mo., a breeder of 

 fancy Poland China hogs, wrote: "None of the vaccinated hogs 

 that were not off feed at the time of vaccination have been off at 

 any time since. On the whole I am very much pleased with the 

 results of our work." Eighty-two head were vaccinated. He 

 had lost several hogs from cholera before vaccination and a num- 

 ber were sick at the time. The vaccinated hogs remained on the 

 infected grounds.
