bean matter, because we experimented with soil bean before they 

 began. We found last year that soja bean produced bad butter. 

 I left it to the fault of the buttermaker. Now Wisconsin station 

 is out with the statement that soja bean silage is rather a danger- 

 ous thing for dairy cows because there seems to be some principle 

 in it which is hostile to the quality of the butter. Is that not 

 right, Prof. Farrington? 



Prof. Farrington : — I am sorry to say, Mr. Smith, I have 

 not read that report thoroughly this year. I did not make these 

 experiments and I cannot answer. 



I was intensely interested in this paper that was given here, 

 and the point about it that made more impression on me, perhaps, 

 than any other was the statement made by the gentleman that 

 people down where he was working are inensely interested in 

 this line of work. About seven years ago I began some of this 

 work, myself, among the patrons of our creamery at the Wis-

I think this is a very encouraging outlook, when in Southern

 having herds of cows tested. I used to be in the state of Illinois 

 and I have been down in Southern Illinois, and I am surprised 

 at this fact and I am sure it is gratifying to me. I would like 

 to ask in regard to this table, how much more milk these cows 

 give than is represented by the milk produced in twenty-seven 

 weeks. Have you any idea? 



Mr. Hopper : — I do not understand your question. 



Prof. Farrington : — You have the average milk per cow for 

 twenty-seven weeks in a year. About how much more milk did 

 that cow produce during the year? 



Mr. Hopper: — That represents the average product in eacn 

 of these herds for twenty-seven weeks the cows were tested. The 

 testing and weighing went on similtaneously in these different 

 herds; some were in an early stage of lactation, some in a late 

 stage, but the tendency is to have the cows freshen either from
