possible to save them. The others we were fortunate in 

 pulling through by a liberal injection of serum. The im- 

 portant point in connection with this incident is this: 

 Though all of those six gilts had the cholera, and three of 

 them died from the disease, yet not one of the 240 immune 

 animals among which they were placed; and with which 

 they had been eating md sleeping, became infected, or have 

 ive seen any evidence or trace of cholera among our animals 

 since, and this was over a year ago. 



Such tests as these are our warrant for the conclusions 

 we have reached that hog cholera can be prevented, and 

 by its prevention be completely eradicated. And the results 

 we have attained are being repeated by numerous other 

 breeders who have adopted the system of simiiltaneously 

 treating their animals and have given the method fair and 

 intelligent handling. 



With us the permanent immunizing of our hogs is a busi- 

 ness proposition pure and simple. The cost is strictly an 

 investment in the way of the purchase of protection that 

 will insure against losses that might reach into the thou- 

 sands of dollars if we were not so protected. 



An important point which should be mentioned is the 

 possibility of carrying, or the transmission of, cholera in- 

 fection from herds, in which the simultaneous method of 

 treatment is employed, to herds which are not immune. 

 For the past year and a half we have shipped hogs and pigs 

 to every section of the United States, and we have as yet to 

 learn of the first instance where any infection has been 

 carried from our herd to other herds, even though those 

 herds had not been given the simultaneous treatment. And 

 further, we have as yet to hear of the first case where herds 

 in our own locality have become infected because of our 

 practice of employing the simultaneous treatment to im- 

 munize our animals. 



It is advisable, however, that care should be taken where 

 hogs are being shipped from herds in which the simultane- 

 ous method is used, and especially so when they are being 

 sent into sections where the animals are not immune. Ani- 

 mals just treated should be held several weeks before ship- 

 ment, and in all cases they should be thoroughly disinfect- 

 ed before being sent out. Upon being received by the pur-
