1906.] DISCUSSION. 257 



Mr. J. HoYT. My experience has been that the cattle Hke 

 cold water better than they do hot. 



The President. There is a great variety of opinion on this 

 subject, the same as with other points in the hfe of the dairy 

 cow. I have found it so. Now there are points that have not 

 been brought out this afternoon, and I would like to have them 

 brought out. 



Mr. Mitchell. During the course of the speaker's ad- 

 dress this afternoon he spoke of the effect of temperature. It 

 may be of interest to the farmers present if I relate the circum- 

 stances of a case in this matter of temperature. There was a 

 large herd of Holsteins kept in New York state, and in order 

 to settle this question of the best temperature they tried some 

 experiments. They began at about forty degrees and increased 

 the temperature to about sixty, taking pains to see to it that the 

 cattle breathed pure air all the time. It was found that they 

 increased the amount of milk. They attempted to keep the 

 temperature at about fifty, as they found that at that point they 

 secured gratifying results. 



I also want to report that at the Vermont Station they car- 

 ried out some experiments to ascertain whether there was any 

 difference between the productive capacity of cows kept in the 

 barn and those let out in severe weather, and put back. The 

 result was in favor of letting the cows out for a little time in 

 the morning. 



Prof, Shaw. I am obliged, Mr. Chairman, for the in- 

 formation just volunteered. I would like to ask, however, if 

 the gentleman knows over how long a period those experi- 

 ments extended. If the cows were kept at that temperature 

 that you referred to I think it would take a number of years 

 to determine the full results. No doubt the present results 

 favor what you say, but what would be your opinion ? 



Mr. Mitchell. This was four or five years. I was in the 

 barn about four years ago. I presume the temperature was 

 not above fifty-two or fifty-three. I know the owner of that 

 Agr.— 17
