on all sides and have a drip pipe to carry off the ice water. The cold 

 room should be tightly ceiled; and not connected with the ice box. In 

 passing in and out of the refrigerator through the cold room, one of the- 

 two doors should alwaysi be closed in order to prevent the cold air fronx 

 rushing out. 



It is generally necessary to have an ice house connected to a cream- 

 ery, where ice can be secured from ice companies. An ice house may be 

 built of single or double walls, depending more or less, on the ease and 

 cheapness' with which ice can be secured in winter. The dlmensionsi of 

 the ice house can easily be determined from a standard. A cubic foot 

 of ice weighs 55 pounds, and an average creamery should have an ice 

 house of 150 tons capacity. It is generally advisable to have the ice 

 house connected with the creamery building. 



All doors in a creamery should be not less than 3 feet 8i inches wide 

 and 6 feet 8 inches' high, except to the receiving rooms, one churn room

The windows, should be large, having not less than four 14x28 inch 

 lights, and should be arranged so as to drop from abovei as wellasbe^ 

 low in order to secure a means of good ventilation. Creameriesi should' 

 be provided with ventilators on the roof and passages connecting with 

 the rooms below so as to carry off the heat and steam. 



Machinery. Not less than a IS-horsie-power boiler should be put in 

 a creamery. A large boiler saves fuel and labor. 'It should always: be 

 one-half greater capacity than engine. The horizontal bricked exter- 

 ior or the ne.w tubular boilers are preferable to the upright style. If the 

 boiler is to be bricked, care must be taken in setting it up. See that the 

 foundation is at least 2i/^ feet deep and grouted well. 



The furnace walls should not be less than 16 inches in thickness, fire 

 box lined with fire brick and stayed with three setts wall stayers. Th'e 

 smoke stack should never be less than 30 feet in height to insure good 

 draft. 



Engine should be set on a good solid foundation fastened with four 

 anchor bolts. The horizontal style is always preferable to the verticaL
