The sides and ceiling of tTie interior building should have at least 

 one coat of shellac; two coats are better. This makes a sort of enamel 

 iinish and can easily be washed. It goes without saying, that the out- 

 side ought to be painted to make the building neat and) attractive. 



The refrigerator for a creamery handling 3000 to 6000 pounds of milk 

 per day needs to be about 8x10 feet including a cold room;. The refrig- 

 emtor proper should at least be 6i^ feet high, and the ice box above: as 

 liigh as it can be made under the rafters, never less than 6 feet. Three 

 dead air spaces are neoessiary for a refrigerator, if the partitions are 

 made of double boards with paper between. If made ofi paper alone, 

 iive dead air spaces are necessary. The latter is the cheaper where 

 simply the paper seirves' as the partitions, and fastened with %x2 inch 

 strips every 16 inches. Care must be taken in securing the best build- 

 ing paper, and see that it is not less than 32 inches in width, so as to fit 

 the studding, when placed 16 inches apart. 



The inside should be ceiled and shellaced. The doors m^ust be m'ad'e 

 same as walls; beveled' and packed with canvas at the edges. The ice 

 box must be connected with the room below by flues construced in the 

 walls. These flues may be the spaces between the studte and joists. 



One flue must receive the warm air at the ceiling on one side of the 

 room- and conduct it tO' the top o^f the ice box, while the cold air flue on 

 the opposite side extends^ diown from the bottom of the icei box in all the 

 spaces betwen the studs to within six inches of the floor, where it should 

 enter the refrigerator room. Th ese flues carry the air after it is cooled 

 in the ice box to the room below. Thus a circulation is kept up by the 

 air coming in contact with the ice where it iscooled, becomes heavy and 

 ..'eturns by its own weight to the room below. At the same time it 

 ^drives the warm air at the top of the refrigerator into the ice box ready 

 to start circulating when cooled. A double circulation can be provided 

 in this way: By converting all four sides into flues, making the refrig- 

 erator more effectual. The air flues leaving the ice box near the bottoni 

 must be arranged so that no ice. or water can enter them. The bottom' of 

 this box should be lined with heavy galvanized iron turned up 3 inches
