JERSEY TESTS. 
During the past winter and spring several phenomenal yields of 
butter were reported in the public press, some of which were so re- 
markable, both in the quantity of butter claimed and in the ratio of 
butter to milk, that the suspicion of some deception haying been 
practiced was quite prevalent even among breeders interested in the 
stock tested. In view of this, and in the hope of discovering the secret 
of these yields, an open letter to breeders associations was issued by 
the Director of the Station, offering the services of a chemist to 
make analyses of the milk and products during a test. 
In response to this letter, Mr. F. Bronson, president of the Amer- 
ican Jersey Cattle Club, invited the Station to send a representative 
to be present at an official test of three cows of his herd. This invi- 
tation was accepted, and I was assigned to the duty. I was present 
with the official tester, Mr. Edward Burnett, at each milking of the 
first five days of the trial, and saw the milk weighed and set. Sam- 
ples were taken of the new milk from each milking, and of the skim- 
milk, butter and buttermilk from the first churning, which were 
analyzed with the results given below: 
The cows tested were Hilda D, 6683, 9 years old, last calf March 
22, 1885 ; Evelina of Verna, 10971, 6 years old, last calf March 31, 
1885 and Edessa, 21844, a two-year-old heifer, last calf March 14, 
1885. The trial began on the evening of June 22, at 6 P. M., the 
cows being milked out at that time, and continued seven days. 
The details of the test as they appeared in the tabulated report of 
Mr. Burnett, are inserted. ;
