II, SAVING OF LABOR. 



There are two general plans upon which creameries 

 have been constructed in the past. One is known as the 

 gravity plan, the other as the one floor plan. In the 

 gravity plan the milk flows by gravity from the intake 

 to the separator, thus dispensing with the use of a milk 

 pump. It necessitates, however, two floors on a different 

 level ; one for the receiving vat, the other, five feet lower, 

 for separators and cream vats. In the one floor plan all 

 vats and machinery stand on one floor, the milk being 

 forced into the separators by means of a pump. 



The chief objection to the gravity plan is that it neces- 

 sitates the climbing of high steps, which makes going 

 from one floor to the other difficult and tiresome. Yet, 

 five years ago, such steps were preferable to the unsani- 

 tary milk pumps then in use for elevating the milk into 

 the separators. With the vanishing of the old unclean- 

 able milk pumps and with the advent of the air pumps 

 for forcing cream into the churn, vanish the chief objec- 

 tions that have always been raised against the one floor 

 creamery. Our present sanitary milk pumps can be 

 cleaned as readily and thoroughly as our milk and cream 

 vats. Moreover our combined milk heaters and milk 

 pumps constructed on the principle of the Reid pasteurizer 

 are practically vats which can be cleaned without the 

 slightest diificulty. Then, too, with our modern cream 

 vats, the air pumps permit the raising of the cream into 

 the churn by means of power. But even if this were not
