BUTTER- MAKING. 



691 



cans are made very deep, as shown in Fig. 856. These cans are 

 placed in the tank about three inches apart, as seen in Fig. 855, A. 

 A milk-strainer, which fits one' of the cans, and through which the 

 milk- is strained immediately after milking, is shown in Fig. 857. A 

 lid which in hot weather'covers the cans, is shown in Fig. 858. 



Pig. 859. — Centennial Milk-pan and Cooler. 



Where the Schwartz system is followed out in its integrity, the 

 cream is not kept jnore than two days during the warmer season, 

 and thr.ee days during winter, before it is churned. 



In, Fig. 859 we present a sketch of an arrangement of improved 

 milk-pans for raising cream, suitable to a dairy of considerable size. 

 Two of the coolers have each two pans, making in themselves^ a 

 complete set, of half the capacity of the full set. The two double 

 pans, as will be noticed in Fig. 860, are connected by a tube, so.that 

 in summer each double pan may act as a single one, while in winter 



it may, by stopping up the tube, be made to act as two distinct 

 pans. 



The interior arrangement 6f the coolers is shown by Fig. 861
