252 CREAMERY BUTTER MAKING 



must be maintained when long keeping quality is desired. 

 Cans. Various insulated cans are now upon the 

 market and a number of these have been tested by the 

 author. The tests showed that these cans possess about 

 the same insulating effect as the felt jackets that are 

 commonly wrapped around ordinary milk cans. The 

 latter, as a rule, are preferred on account of their greater 

 ease of handling. The insulated cans, however, have an 

 advantage in the extra cover inside, 

 which can be pushed to the top of the 

 cream, thus preventing it from churn- 

 ing when the cans are only partially 

 filled. 



Hauling Cream. In gathering 

 cream the most satisfactory results 

 are secured by providing a separate 

 can for each patron. The driver 

 starts out with a load of clean, empty

along the route. This method gives the buttermaker 

 an opportunity to examine each patron's cream, leaves 

 in his hands the important matter of sampling and 

 weighing and also insures clean cans for the patrons. 



Where there are too many small producers the above 

 plan has the objection of requiring too many cans for 

 the amount of cream collected. With producers of this 

 kind the common method is to weigh and sample the 

 cream at the farm and empty the same in large collecting 

 cans. Where the patrons' cream is hauled to the cream- 

 ery in separate cans, the latter must bear, upon brass 

 plates, either the patrons' names or numbers corresponding 

 to the names.
