No. 4.] MILCH COWS. 37 



and also extend well forward. This udder conserves rather 

 than wastes nervous energy. 



The more you seek the comfort of the dairy cows, the larger 

 will be the output. 



Right here I want to raise another point. I leave it for 

 others to discuss. I have noticed repeatedly in my own 

 State that wherever there is an outbreak of tuberculosis it is 

 always in the best animals of the herd, — the heaviest pro- 

 ducers. 



Is it not true that the animal which gives you six thousand 

 pounds of milk requires more oxygen than the animal giving 

 three thousand? Too many of our barns are built on the 

 three-thousand-pound plan. May we not find the solution 

 of this question by opening our tie-ups and increasing our 

 conception of what six thousand pounds of milk must mean 

 to the machine ? Are we not putting an obstacle in the way 

 of that machine performing as it would otherwise perform ? 

 By increasing the amount of air in our tie-ups may we not 

 find one of the steps by which we may increase the output 

 of the individual cow? 



The Chairman. The Doctor will be ready to answer 

 any questions that may be asked him, and I hope many 

 will question him. He is able to bear it and ready to 

 answer. 



Mr. Geo. E. Taylor (of Shelburne). I would like the 

 speaker to explain what he means by mental control. 



Dr. TwiTCHELL (turning to chart). Here, at the brain, is 

 the seat of milk production ; here, at the udder, the source 

 of supply. As the channel between this point, the brain, 

 and the udder is most free and open, so, other things being 

 equal, will the supply be largest. I mean first of all the 

 development of the natural functions of the brain which tend 

 in a cow in one direction or the other, — tend, I say, either 

 in the direction of milk or beef. In one way or the other 

 the natural tendencies will be set if left to themselves. 

 We intensify through our own individual conceptions, our 

 treatment, our care, our feeding. No man can lift produc- 

 tion above the standard of his ideal. We come nearest to 

 that when it is more clear. It is the positive, purposeful
