ordinary barrel or milk tank to keep the cream in. It will only 

 cost you from $3.00 to $10.00 to fix a place of that kind and it 

 will take care of the milk or cream on the hottest day in summer. 



In handling and caring for cream there are so many things 

 that are overlooked. I have visited farmers in the afternoon 

 when cream separated in the morning was still standing by the 

 separator and when I have said to the man : "Why don't you put 

 that cream away to cool?" he said, "I will do that before I com- 

 mence separating." He said there was no difference between 

 leaving the cream standing there several hours and cooling right 

 away. It is this, you have given the bacteria a chance to multiply. 

 You will have thousands more, especially in the warm weather. 

 You must remember, although you cannot see these rascals, they 

 are the cause of these troubles that we meet with in manufac- 

 turing dairy products. It makes a big difference whether the 

 milk is left a half hour or a whole hour. If for no other reason 

 for this, when milk is first drawn most of the bacteria gets in 

 from the outside. There are only a few that the cow has put in 

 herself, they are gathered mostly from the air and from the hair 

 of the cow. The majority are in an indolent condition, and it 

 takes from twenty to thirty minutes for them to become active. 

 When they get into the milk it is an ideal place for them to 

 live and grow, but it takes from twenty to thirty minutes to 

 become lively. If you can bring the temperature down as low as 

 possible, say 60 degrees or lower, inside of twenty minutes you 

 can practically get them under control as chilling them puts them 

 in an inactive stage. The majority do not grow rapidly when' 

 you get them down to that temperature. If you cool at once a*;- 1 

 keep it cold the cream will keep from four to five times as long. 

 Therefore, the cream should be cooled at once as soon as possible 

 after separating. 



Now I do not know whether it would be worth while to say 

 anything about the separator particularly. If you have had any 

 difficulties and have any questions to ask, do not be afraid to 

 ask them. 



Member : Do you not believe the co-operative creamery is 

 a good thing?
