sar}^ if the milk is to be properly handled. FHes and other insects may- 

 be kept out of the milk house by having the doors and the windows 

 properly screened. A good supply of fresh water is one of the require- 

 ments of a well-equipped milk house. 



The milk room should be provided with faciHties for heating a liberal 

 supply of water for 

 washing and sterilizing 

 the utensils. This may 

 be done on a stove or 

 by turning steam into 

 a half barrel. Either 

 boiling water or steam 

 will do efficient steriliz- 

 ing if properly used. If 

 a supply of steam can 

 be had, the sterilizing 

 process can be simpli- 

 fied by placing all of the 

 utensils in a sterilizer, 

 where they are all 

 treated at one time 

 with less labor than is 

 necessary to thoroughly 

 scald each piece with 

 boiling water. There 

 are several forms of 

 good, efficient sterilizers 

 on the market of the 

 general type shown in 

 figure 136. All of the 

 utensils used during the 

 entire day can be steri- 

 lized at one time in 

 one of these machines. 

 Larger forms of stationary sterilizers can be built of concrete or hollow 

 tile, as shown in figure 137. If a steam sterilizer is used, the utensils 

 will be dried by their own heat if the steam is allowed to escape immedi- 

 ately after the heating period. The door can then be closed, and the 

 utensils are thus protected from contamination until ready for use. The 

 length of time necessary to sterilize the utensils, or to heat the sterilizer 

 and its contents to the temperature of the steam, should be determined. 

 In the small iron sterilizers, this requires only a few njinutes, while in
