should be thrown over them. When dehvery is not made for 

 thirty-six hours, as on account of holding over Sunday, the milk 

 should be held at a lower temperature than when delivered within 

 twelve or fifteen hours. 



In order to prevent the absorption of odors by milk, the 

 place where it is kept must be free from any objectionable smell. 

 Cold milk absorbs odors very rapidly. Water in the tanks must 

 be kept sweet by frequent changes, and the shelves, walls, and 

 floor must always be clean. Covers of the cans may be left on 

 or off, but if there is any danger of contamination, the cans 

 should be closed tightly after the milk gets cold. 



Evening and morning milk should not be mixed, especially 

 when the fresh milk has not been cooled. If this is done, the 

 whole lot soon spoils. In order to insure the same quality of 

 milk in each can, large tanks are frequently used for mixing all 

 the milk of one milking. This is a matter of some importance 

 when a sample from one can is used for determining the value 

 of the lot, or when the milk is sold at retail. 



The use of preservatives is mentioned at length in Farmers' 

 Bulletin No. 42, U. S. Department of Agriculture, Facts About 

 Milk. Some of them are dangerous to the health of the con- 

 sumer, and any of them may be harmful if taken regularly in 

 milk. They are prohibited by some state laws, are condemned 

 by leading authorities, and should not be used. 



HAULING TO THE FACTORY. 



If milk is sold off the farm, the dairyman's care of it does 

 not cease until he has delivered it to the factory or other desti- 

 nation, and then he has a right to insist that it be properly 

 handled, if he is interested in the success of the concern which 

 uses his product. 



Milk should be hauled in spring wagons and the cans filled 

 full to prevent churning while on the road. Much trouble is 

 caused by allowing it to stand an indefinite period on a platform 

 in the heat waiting for the collector; the storage tanks should be 

 placed so it will not be necessary to remove the cans from the
