bred into her. It is just like a boy that has got into bad 

 habits. He gets going in a certain way, and it takes some 

 time to reform him and get him right. 



Mr. Stone. I had some experience in feeding a small 

 amount of grain, corn fodder and some grass to a Jersey 

 cow. I got a small quantity of milk, but I could not see 

 but that the cream was just about as thick as if she had been 

 grained more heavily. I am well aware that by increasing 

 the feed we can increase the amount of milk, but the ques- 

 tion is, whether we get more cream. I have about made up 

 my mind that increasing the feed increases the amount of 

 milk more than it does the cream. 



Professor Roberts. It is more likely to, but you can 

 increase the butter fat. 



Mr. Bowker. Where doctors disagree, I do not know 

 what we laymen are going to do. Some of us were at 

 Fitchburg last year, and we remember that Professor Cooke 

 of the experiment station, and Mr. Douglas, whose lecture 

 we all prized very highly (he has now passed to the other 

 side), got into a very animated discussion over this question 

 of heating water for cattle. Mr. Douglas took the ground 

 that water should be heated ; Professor Cooke, as our 

 secretary will remember, said he could prove by his experi- 

 ments and records that his- cows gave as much milk when 

 they drank cold water, but were not exposed to the weather, 

 as they did when they drank warm water. 



Professor Roberts. What was the temperature of the 

 warm water? 



Mr. Bowker. The chill was taken off. So much for that 

 point. I am not here to criticise Professor Roberts ; I only 

 want to make these remarks to bring out the point more 

 clearly. You have just stated that we can increase the per 

 cent of solids by the food that we give. Now, am I correct 

 in understanding you to say that you can also change the 

 percentage of the fat and caseine by improving the quality 

 of the food fed ? 



Professor Roberts. That is not so certain. 



Mr. Bowker. I think some of those around me under- 

 stood you to say that you could increase the fat by feeding 

 a different quality of food.
