 not tlie sliglitest sign of a reaction among them. We have had 



ID more treated this winter Would also say that we believe 



it is such a good thing, that no dairyman should be negligent 

 enough not to use it. The calves all keep growing steadily, 

 and we never had one miss a feed, or show any signs of being 

 sick after receiving the treatment." 



The Cattle Commissioner of the state of Maine has this to 

 say, in a letter dated January 8, 1910 : 



" During the past four years our experience with Bovovac- 

 cine has been considerable, and I wish to assure you that the 

 results have been exceedingly satisfactory. The work of im- 

 munization has been carried on in some of our worst infected 

 herds, and I feel that it has been given a severe test. The re- 

 sults have been such that it seemed a valuable adjunct in our 

 work of eradicating tuberculosis ; consequently, at the last ses- 

 sion of the lyegislature a law was passed, providing Bovovac- 

 cine free of charge to the breeders of this state. Many breeders 

 are availing themselves of this opportunity to build up immune 

 herds, and I trust the number will increase."
