bottle can best be quickly chilled by holding the side of the bottle 

 under running water at such an angle that the milk is not spilled 

 nor the cotton plug wet. 



5. As soon as the milk is cold it should be set in the ice box 

 near the ice until needed. A full day's supply may be pasteurized 

 at one time in the manner described, but all pasteurized milk 

 more than twenty- four hours old should be thrown away. 



There are several forms of home pasteurizers on the mar- 

 ket. One in particular (Freeman's pasteurizer) is very conven- 

 ient, as it automatically keeps the milk at the right temperature 

 for the proper length of time. 



The Use of Vacuum Bottles. 



Vacuum bottles may be safely used for keeping milk cold for 

 many hours. They are particularly convenient for maintaining 

 milk at a low temperature while traveling, and for keeping it 

 cold in the bed chamber, where it will be handy for the night 

 feeding of infants. 



Vacuum bottles should never be used for keeping milk warm, 

 since in warm milk rapid growth of bacteria will inevitably take 

 place and cause the milk to become unfit for food many hours 

 before it sours. 



Visit Your Dairy. 



Unless you live in a large city where the milk has to come a 

 long distance, visit your dairy and see for yourself how it is con- 

 ducted. Insist on the wiping of the cows' udders with a damp 

 cloth before they are milked, and on the milkers using covered 

 milk pails. To keep dirt oat of milk is not difficult, but to 

 strain it out completely is impossible. 



A dairyman who knows that his customers are likely to 

 visit him is pretty sure to keep his cows and utensils clean. 



In many of the larger cities the milk inspector or the health 

 officer can give information as to sanitary quality of milk sold by 

 the various milkmen.
