and she was giving then from twenty-five to twenty- 

 seven pounds of milk a day. I tested her for five days, 

 and in those five days I made ten pounds and nine 

 ounces of butter from those weights of milk per day. 

 That was the way she ranged. So that showed me, 

 as I think, that the feed did have something to do with 

 it, and that the increase in butter fat was not in pro- 

 portion to the quantity of milk that she gave. When 

 she gave forty pounds of milk she produced less than 

 two pounds of butter, and when she gave twenty-five 

 pounds she produced over two pounds of butter. 1 

 think that case is at variance with Mr. Sawyer. I 

 want to say this ; that I have never been able to find any 

 record where any individual cow was taken and highly 

 fed for a long period of time and then tests made ; that 

 is, a test begun in the beginning, and the feeding and 

 the testing continued for a year or eighteen months. 

 If you have noticed all these high yearling tests you 

 will remember, for instance, Mary Anne of St. Lambert, 

 and Bisson's Belle; you will notice that the effect from 

 this long feeding is to get more butter out of a small 

 quantity of milk, and I think that right in that point is 

 where Mr. Sawyer is mistaken; that in all the tests 

 that he has enumerated the feeding of the cows has 

 been for a short time, not for a long time. 



Mr. Sawyer : On this last point I would simply 

 state that the Cornell University has kept account of 

 the percentage of fat. Remember the percentage of 

 fat is a little bit different from setting the cow's milk 

 and churning it, one year with another, because it is 

 utterl} 7 impossible to get your conditions exactly the 

 same every time as far as making the butter is con- 

 cerned, while the percentage of fat is the same, no 

 matter what the cow gives. In this case, where the
