the evening- milk until after cooling. There is always 

 some bacterial growth even if the evening milk was well 

 cooled. By mixing the warm morning milk with the 

 evening milk and thus raising the temperature several 

 c'egrees, a vigorous fermentation may be started, spoiling 

 the milk before it arrives at the creamery. 



If the evening milk is shipped in separate cans, care 

 should be taken to mix the cream, in the top layer of the 

 can, with the other contents of the same by stirring 

 thoroughly before transportation. If this is neglected 

 the cream may churn out during transport or, in case 

 some accident happens, is likely to be lost. In both 

 cases the milk will show a lower butterfat-test. 



The transport is preferably done with a spring- 

 wagxm or truck. The bottom of the vehicle must be kept 

 in a clean condition by frequent washing with an abund- 

 ance of water. Dirty bottoms of milk wagons are an 

 important source of contamination of the milk. The dirt 

 often adheres to the bottoms of the cans and drops in 

 the weighing tank when the milk is dumped therein. 



For the same reason the milk-stands at the road- 

 sides should be kept clean. 



In extreme weather, the cans may be protected by 

 covering with a cloth or felt hoods. 



Return Products 



Skimmilk, buttermilk, whey, etc., returned to the 

 farm for feeding purposes, should never be put in cans 

 that are used for fresh milk transport- Special cans 

 must be used for that purpose, as it is nearly impossible 

 to clean such cans on the farm so well that fresh milk 

 can safely be put in without endangering the quality. 

 ]\lilkcans must never be used for anything else but milk. 



The Cleaning of Milkcans 



If the cleaning of the milkcans is done by the 

 creamery, the dairyman should convince himself that the
