72 DAIRYING 



The Cream Hauling 



362. It often happens that cream which has been well cared 

 for at the farm is damaged during transportation to the creamery. 

 The cream gathering wagon starts out early in the morning-, and 

 the first cream which it collects must remain in the wagon until 

 it returns at night. This trip when taken in the hot days of 

 summer or the cold days of winter is likely to be injurious to 

 the quality of the cream. An efficient protection from these ex- 

 treme temperatures is a problem which must be solved if the 

 butter made from such cream is to grade as extra in quality. 



Sampling- Cream 



363. When cream stands for any length of time the top 

 layer will be richer than the cream below; this makes it neces- 

 sary to thoroughly mix each lot of cream by pouring from one 

 can to another just before taking a sample for testing. If the 

 cream is lumpy it should be poured through a fine hair sieve 

 before sampling. 



364. Gathered-cream factories have in some cases adopted 

 the following method of sampling cream : Each driver is pro- 

 vided with a box of numbered bottles having a capacity of about 

 four ounces each, one bottle being provided for each patron. 

 This box is protected from heat in summer and cold in winter 

 so that the sample bottles of cream may arrive at the factory in 

 nearly the same condition as when taken from the farms. This 

 gives the butter maker a chance to inspect each patron's cream 

 and locate the defective lots, if there are any. 



365. After inspection at the factory the samples are either 

 tested before souring or poured into composite sample jars which 

 contain a preservative, no preservative is added to the bottles 

 taken to the farms by the man who weighs, samples and gathers 

 the cream, but he must protect these samples from changes 

 caused by heat and cold during the different seasons of the year. 



In some factories each lot of cream is tested as received. 

 This is considered more accurate and satisfactory than tests of 

 composite samples.
