72 BOAKD OF AGRICULTURE. [Pub. Doc. 



would not be troubled again for an hour and a half or two 

 hours ; and I found that it is not only a great comfort to the 

 cow, but also favorably affects the yield of milk. I sprayed 

 the cows in the morning, but you all understand very well 

 that kerosene oil evaporates very quickly, and it does not 

 last probably more than two hours. A very small quantity 

 can be used. It kept them as quiet as in the middle of 

 December or January. I let them out after milking, and 

 when they are returned to the stable I again use the sprayer. 

 I supplement their pasture feed with oats and peas. 



The Chairman. I see Mr. Sanborn present, and I would 

 like to hear from him. 



Mr. C. E. Sanborn (of Boston). I believe I was never 

 called upon before or ever spoke in public, but I must say 

 that this discussion in reference to flies has been of great in- 

 terest to me in view of the experience which I have had in the 

 last two years. I have quite a large stock farm, for New 

 England, of horses, and during the season of 1892 in Maine 

 we were troubled more than usual with flies of difierent 

 varieties. My stock would come in from the pastures sim- 

 ply worn out from fighting flies, and required a good deal 

 of extra feeding. I was recommended this season by an 

 old veterinary to use rancid fish oil with boiled sage. The 

 boys went into the pasture with a pail and an old paint brush 

 and put some of this on the animals, in two or three places, 

 perhaps once in three days, and they were free from the 

 trouble of flies. You could see them feeding all day long 

 in the sunshine, and we had no trouble whatever. 



Mr. Hartshorn (of Worcester). I would like to know 

 why the use of fish oil would not be beneficial on milch cows. 



The Chairman. I would like to ask Mr. Clemence as to 

 the use of kerosene. Did you discover that it had any effect 

 upon the milk in any way? 



Mr. Clemence. Not a particle ; but I found that if you 

 sprayed the cow immediately before milking you could smell 

 kerosene in the stable, although I never detected it in the 

 milk. But it seems to me that it would be advisable to wait 

 ten or fifteen minutes after applying the kerosene before 

 commencing to milk. By that time I do not think you will 

 have the smell in the stable.
