MARKET DAIRYING 



Enough windows must be provided to afford ample 

 light and to admit sunshine to all parts of the building. 



Provide ventilation in the milk and wash rooms by 

 running tight ventilating shafts from the ceiling through 

 the top of the roof. 



Sewerage i Effective sewerage must be provided at 

 the time the floor is laid. A bell trap (Fig. 58) should 

 be placed in the center 

 of each room and care- 

 fully connected with the 

 sewer. Conduct the sew- 

 age far enough away to 

 keep its odors a safe 

 distance from the dairy 

 house. See chapter 

 XXVI. 



Method of Warming 

 Dairy Houses. Dairy 

 houses should' be heated with steam, not with stoves. 

 Either the exhaust steam from the engine or steam taken 

 directly from the boiler may be used for this purpose. The 

 heating pipes should be so arranged that either may be 

 used when desired. 



A very satisfactory method of piping is to run one and 

 one-half inch pipes from the boiler to within two feet of 

 the floor, and close to the walls. The pipes should pass 

 around each room and end in a steam trap which dis- 

 charges the condensed steam into a hot well located near 

 the injector, so that the hot water may readily be drawn 

 into the boiler. The heating pipes must all slope towards 

 this well. 



A reducing valve should be placed near the boiler so 

 that any amount of pressure may be carried in the heat-
