1882.] SETTING MILK. 305 



trates this in a striking way, and confirms the observation with 

 exact numerical results. 



This temporary disturbance has been observed in dairies all 

 over northern Europe, and since it most frequently occurs in 

 autumn, it has been behoved that the milk of cows near the end 

 of their lactation, had this peculiar quality of working badly by 

 the Swartz system. Experiments in Denmark confirmed this view. 

 In November and December, 1876, Fleishman carried out com- 

 parative trials in the Eaden Experiment Station with milk from 

 three cows, which had calved on March 4, April 1, and April 7, 

 and were old in milk, and from three others lately calved, on 

 November 3, November 13, and December 2, new in milk. In 

 the case of two cows old in milk the yield of butter was less at a 

 low than at a medium temperature (59°-62°). 



But milk from the third cow, old in milk, which calved April 7, 

 gave more butter when set at a low than at a medium temperature. 



The milk from two cows fresh in milk yielded better when set 

 at a low temperature, the milk from the third yielded best at 59°- 

 62°. From these results Fleishman concludes that if this trouble 

 about the prompt rising of cream is move frequent with cows old in 

 milk, it is not by any means confined to such. 



In the Raden dairy the quantity of butter, produced from the 

 herd began to diminish rapidly from the second week in October, 

 1876, a time when many cows were toward the end of lactation, 

 and the change from summer to winter feed was being made, and 

 did not fully come up again to the previous yield till some time 

 in December. The same thing occurred again in the spring of 

 1877. 



On the fifth of May the decline began, and to make one pound 

 of butter there were used 



On May 20, 1877, 38 lbs. milk. Stall feeding. 



It should be said that deep setting was practiced here through- 

 out. The yield improved at once when the cattle went to pasture, 

 and in this herd of 128 apparently healthy cows the yield of but-
