312 BUTTER-MAKING. 



The butter was disposed of locally while fresh. In cream- 

 eries where it is necessary to hold butter any length of time, 

 this system is undoubtedly less satisfactory, but under above 

 mentioned conditions it gave good satisfaction. 



The water-tank should never be made from wood, as wood 

 is a very poor conductor of heat. Heavy galvanized iron is 

 best. 



NATURAL ICE SYSTEM. 



Kind of Ice-house. When natural ice is stored, the first 

 consideration is a good ice-house conveniently located to the 

 creamery and refrigerator. When the creamery is first planned 

 and built the ice-house should at the same time be provided 

 for. The ice-house should preferably be adjacent to the re- 

 frigerator, so that the ice can be transferred directly from the 

 house into the cooler, thus obviating much loss of ice and 

 decreasing labor. 



The various parts of the building embracing the many 

 details, will not here be enlarged upon, inasmuch as they can 

 be more advantageously shown in plans. Students are referred 

 to the different views shown on pages 313-315, 317 and 318.* 



As will be seen, the construction of the ice-house depends 

 to some extent upon the location and kind of refrigerator to 

 be used. There are at least two different ways of locating 

 the refrigerator in relation to ice-house: (1) Where the re- 

 frigerator is entirely separate from the ice-house, the ice to be 

 transferred and placed either overhead or on one side of the 

 refrigerator. (2) Where the refrigerator is combined with 

 the ice-house and the ice is not moved for cooling purposes. 

 This in turn may be arranged so as to have the ice storage 

 overhead or on one side of the refrigerator. The ice-house 

 needed in connection with this second method differs chiefly 

 from that of the first in that better insulation is necessary 

 and no ice-packing material is used, except on top. This latter
