of skim milk were taken from each can. There was no percepti- 

 ble difference in the bulk of cream. 



The different lots of cream were then ripened and on February 

 21 were churned all at the same time in the same test churn. 



The butter was washed in the granular state, allowed to drain 

 thoroughly and weighed without working or salting. The results 

 were as follows : 



No. I, 1. 03125 lbs. 

 No. 2, 1.1875 lbs. 

 No. 3, .9375 lbs. 

 No. 4, .9375 lbs. 



The butter so far as we were able to judge was very uniform in 

 quality from all the lots of cream. These results gave no confir- 

 mation to either theory. We had no pasty, cheesey butter, and 

 the difference in weight, as we afterwards learned, was in all pro- 

 bability due to a varying percentage of water in the different sam- 

 ples of butter 



Thinking that a larger quantity of cream churned in an ordi- 

 nary churn might give us results more comparable with actual 

 practice, the experiment was repeated as follows : 



No. I February 26th, 1889, ^^^^ mixed evening milk from the 

 same Jersey cows used before. 48 pounds set without treatment 

 at go degrees. 



No. 2, February 27, 1889. Same amount of the evening milk 

 from the same cows. First cooled to 60 degrees by pouring from 

 can to can, then warmed to 135 degrees and .set. 



No. 3, February 28, 1889. The mixed evening milk of five 

 grade Holstein cows. Tliree had dropped calves in September, 

 one in August, and one in October, 1888. 48 pounds of milk set 

 without treatment at 88 degrees. 



No. 4, March ist 1889. Same amount of milk from the same 

 cows as No. 3 set in the same manner as No. 2. 



In this trial all the milk was skimmed after setting twelve hours, 

 ripened, and churned in an ordinary barrel churn. The results of 

 the churnings were as follows : 



No. I Jerse\' cows, untreated - 3.15625 lbs. 



No. 2 " " warmed to 135° - 3.25 



No. 3 Holstein cows, untreated - 2.0625 



No. 4. " " warmed to 135° 2.25 " 



The.se results as far as they showed anything indicated the ac-
