many milkmen in this county and in the State. My cows 

 last winter would go to drink and put their noses in the cold 

 water and throw them up, and I had one cow that would not 

 drink for from a quarter of an hour to twenty minutes, and 

 then not nearly as much as she would if the chill had been 

 taken from that water. I think that cold water, if taken 

 into the system, prevents the animal from assimilating its 

 food properly. I believe that the chill should be taken from 

 it, but it does not seem to me that it can be practicable for 

 farmers generally to heat the water to the degree which has 

 been suggested. 



Professor Roberts. I presume, gentlemen, you want 

 your tea and coffee more than lukewarm, and my word for 

 it, your cows are just like yourselves. It is all on the same 

 principle, according to the same law. We have been all 

 over this thing, tested it and tested it, and we know that 

 a cow likes water a great deal better when it is about ninety 

 degrees, than at a lower temperature. 



Mr. S. A. Newton of Auburn. Do you warm the 

 water in the summer season, or only in cold weather? Our 

 running water is below ninety degrees in the warmest 

 weather, and, if it is worth while in the winter to heat it to 

 that particular temperature, why not in the summer? 



Professor Roberts. Because the cow gets too hot in the 

 summer, and she likes to have something that will use up 

 the superfluous heat. In the winter she has not that super- 

 fluous heat, and wants her water quite warm. 



Mr. Newton. Why not heat the water above ninety 

 degrees ? It seems to me you have not got it up to what 

 will be really palatable. Certainly to a man it would be 

 rather lukewarm at ninety degrees. 



Professor Roberts. The reason for fixing that point is, 

 that, if you go much above ninety, the danger is that you 

 will get it too hot, and the animal will burn its mouth. It 

 is a safe point. 



Secretary Sessions. Will the professor tell us the best 

 method of applying banvyard manure ? 



Professor Roberts. I should practice applying it in the 

 fall, on the surface where the plants are growing. Our 

 conditions are different in different places, and we have
