Mr. Eeed: Is there a difference between the morning's 

 and evening's test? 



Prof. Haecker: Some cows give it one way and some the 

 other. 



Mr, Monrad: If I remember right, in your report, yon 

 had a variation from 2.6 to 4.1 in one cow during one week, 

 so we don't want always to say that the creamery man is 

 making a wrong test. 



Mr. Judd: Is it not true that the variations in a herd 

 of cows about offset each other, so that a test made twice a 

 week would give very closely the average production? 



Prof. Haecker: Yes, I think it would. I would like 

 to read a few of the tests we have made.

Mr. Hostetter: How much will a cow vary from day 

 to day? 



Prof, Haecker: Some vary 1 per cent, and some vary 

 but little. It depends somewhat on the cow. I have a few 

 of these tables here, if any one wants them they can have 

 them. 



(The bunch of printed tables handed out by the Professor 

 was very promptly taken and loud calls were heard for more). 



Mr. Dean: In feeding corn fodder, did you feed it whole, 

 or did you run it through a shredder or cutter?
