If a large can of recently pasteurized milk has been cooled below 

 100° F,, the contents of the jar from which the transfer was made may 

 be emptied into it, thus completing the work of preparing a starter 

 for use on the following day for ripening large quantities of cream. 

 By this method only a quart of milk out of a large can of starter has 

 been sterilized, a quantity too small to be detected in the cream or 

 butter. 



To meet the needs of the busy creamery man, a table of daily direc- 

 tions in short form, follows. The directions will call the attention 

 of the beginner to operations necessary to the successful management 

 of starters by the sterilizing method. This is a simple and easy method 

 to follow. A very convenient method is to sterilize several bottles at 

 a time and put in a cool place for future use. In this way enough 

 can be sterilized at one time to last a month or more. 



* In preparing Jar 1 the transferrer should not be omitted. 

 t No transfer should be made until milk is below 100° F.

The method of carrying mother starters in sterilized milk in glass 

 jars has Keen given a thorough trial in practical work in the College 

 creamery in comparison with the method commonly employed, which 

 is to inoculate a starter each day from the one prepared the preceding 

 day. The new method has the following advantages: 



The starter can be kept pure for a much longer period, thus saving 

 one-half or more of the cost of pure cultures. 



The milk is always ready for inoculation and the mother starter 

 can be transferred each day when in the best condition and kept 

 vigorous. 



In case a starter is not needed every day, the mother starter can 

 be carried along conveniently without the trouble of sterilizing milk. 



After a thorough trial we have adopted the method for our daily 

 use. We find it no great task to sterilize the bottles of milk once or 

 twice a month, and the little extra labor thus occasioned is more than 

 offset by the convenience and sureness of the new method.
