The size depends on the kind and amount of machinery to be used. It 

 should be as s/imple as possible. 



It is desirable to have a good separate foundation for a cream sep- 

 arator, but for many machines a solid floor foundation will be suflicient. 

 Never purchase a horizontal steam or other surface cylinder pumps, 

 Rrithout measuring or knowing the height of the column of water to 

 which it has to be lifted. The limit of suction for an ordinary pump 

 is 27 feet. If the surface of the water falls below 27 feet a d'eep well 

 pump must be used. 



In purchasing the remaining parts of the outfit, it is best to buy on 

 30 or 60 diays' trial. If there are any flawsi in the separators' bought, 

 they will by this time be discovered. 



Water and steam' should be piped to all vats, sink churn, and skim 

 milk tank. The skim' milk tank should be lined or made of galvanized' 

 iron, and be placed high enough for a wagon to drive under and draw off 

 the milk by simply opening a valve. The ground around this place 

 Bhouldl be paved in such a way that the drop will run off into the sewer. 

 It is necessary to flush this' place every day for sanitary purposes. 



This milk can be elevated by means of a pumip or steam jet. If a 

 checked pump is used this is not necessary. The exhaust steam of the 

 engine should be utilize-di for scalding the skim milk in order to keep it 

 sweet until fed. The arrangement must be convenient so that the per- 

 son in charge can easily clean and steam it every day. 



The cost of a creamery depen ds mostly on the local cost of materials 

 and building expense in general. As an estimate it requires $2,500 to 

 |3,30O to complete a creamery having a capacity to handle the milk from 

 iOO to 500 cows at the present tim.e.
