jection with every cow that calves on my premises simply 

 as a preventive, which is one part bichloride of mercury 

 and 4,000 parts of water, and I use a gallon of that injec- 

 tion at a time. I wash the vulva and the tail and all 

 the parts very carefully, and disinfect the barn all over, 

 and wherever the cow has happened to drop her calf 

 with sulphuric acid one part in one hundred. My 

 theory of the disease is that it is a germ that passes 

 from one cow to the other, in what way nobody has 

 yet been able to understand, nor how that germ is 

 developed ; but that it is developed we know. If you 

 have a case of that kind the best th*ing to do is to 

 immediately take the cow away from all the others and 

 keep her separate. I have never had more than one 

 case at a time in. my herd, although I am milking 

 thirty-six cows ; and since I have adopted this course I 

 have had very little trouble. I have also fed phosphate 

 of lime by mixing one part phospate of lime and six 

 parts salt, and giving them a tablespoonful every day 

 of the mixture. I prefer the phosphate of lime to 

 ground bone, because it is purer and it costs very little 

 more. 



Mr. Lloyd : Do you feed that right along during the 

 whole season, or only just as they come near calving? 



Mr. Boyd : Sometimes I feed it the whole season ; 

 it is a good milk food . 



Mr. Lloyd: Do you think that feeding oil meal 

 tends to bring on abortion? 



Mr. Boyd : No, sir, I do not. 



Mr. Gurler: I think that it is true that if you give 

 a cow an overdose of most anything it might produce a 

 tendency that way, but I do not think that oil meal has 

 any special tendency in that direction. In my opinion 

 of the two cottonseed meal would be more dangerous,
