cream from each portiou was weighed, analyzed, and after a suffi- 

 cient quantity had been collected the whole of each lot was cluirned, 

 and the weight of butter ascertained. Six trials of this kind were 

 made, each trial including the milk of three cows for four to five 

 days. The temperatures at which the different portions of milk 

 were set ranged during the six trials 35** to 60° F., these limits being 

 those stated to be used by the patrons of Maine butter factories. 

 Below is a summary of the results of these trials.

Different Temperatures. 



In every instance the colder milk has furnished the larger volume 

 of cream. 



The following summary shows the extent of the differences in the 

 six trials. 

 First Trial, colder milk 35°, warmer milk 40° to 45°, colder milk gave 



22.3 per cent more cream. 

 Second Trial, colder milk 35°, warmer milk 45° to 48°, colder milk 

 gave 19.2 per cent more cream.
