Cream Raising by Dilution. 



It is well known that where cream is separated from milk by 

 the deep setting gravity process^ the best residts are obtain,ed 

 where the temperature of the milk is quickly brought down t/O 

 and maintained at about forty degrees for twelve hours. The win- 

 ter of 1889-1890 was so warm and open that many dairymen failed 

 to secure a supply of ice and in the ensuing summer began to 

 suffer loss because they were not able to sufficiently lower the 

 temperature of the water surrounding the cans in their creamers. 

 To obviate this difficulty it was recommended that water should 

 be added to the milk to facilitate the creaming. Two diiferent 

 systems were mainly recommended: One, that twenty-five to 

 thirty-three per cent of hot water (135 degrees F.) be added to the 

 milk in order to raise the temperature of the whole mass to at 

 least 100 degrees, so that in cooling down as low as poissible — 

 usually to about sixty degrees F. — there would be approximately 

 the same range of fall as there would be in cooling down to forty 

 degrees with ice. The other recommendation, was that an equal 

 bullv of cold water (sixty degrees) be added to the fresh milk before 

 setting. This was based on the idea that the increased fluidity 

 thus given to the milk would render the creaming process as com- 

 plete as though the milk were cooled down to forty degrees with 

 ice. 



Since that time, experiments to test the value of these recom- 

 mendations have been conducted at several of the experiment 

 stations and the results are found in the following publications: 



University of Illinois Experiment Station Bulletin No. 12, page 

 376, and Bulletin No. 18, page 30. Ck)rnell University Agricul- 

 tural Experiment Station, Bulletins Nos. 20 and 29. Vermont 

 Agricultural Experiment Station, Newspaper Bulletin No. 3, and 

 Foui-th Annual Eeport, pages 100-107. 



The results of these various experimentis have not been entirely 

 concordant; although in the main they have not been favorable
