ordinary tin funnel. It must be remembered that cow manure 

 and other filth dissolves fairly readily in milk, and that for every 

 particle of dirt found in milk an equal quantity has probably 

 gone into solution and thus become invisible, just as sugar 

 dissolves in water and leaves no trace. Milk that is dirty is unfit 

 for food. It is much more important to secure clean milk than 

 rich milk. 



Take Milk Into the House Without Delay: Keep It Cool. 



Milk should be, and in many cities is delivered to customers 

 at a temperature of 50 degrees F., or less. It should be taken 

 into the house at once and put in a cool place, preferably into an 

 ice box. Milk that is left out-of-doors is exposed to dust blown 

 in from the street that settles on the neck and cap of the bottle. 

 Such dirt is partly composed of horse droppings, human sputum 

 and other filth. In summer milk will warm up quickly to a 

 point where the germs increase rapidly, causing the milk to sour 

 early, and, if filth bacteria are present, to become unfit for food. 

 Moreover, as the milk grows warm it expands and leaks around 

 the cap of the botle, thus attracting flies from the privy, ma- 

 nure heap and other filth, and possibly also inviting visits from 

 cats and dogs. 



In winter milk keeps cold out-of-doors, but as it freezes it 

 expands and forces out the cap, and so it is often exposed to the 

 dust of the streets and to animals to a greater extent than in sum- 

 mer. 



If milk is not delivered in bottles, a Mason jar, or some other 

 covered receptacle, should be put out for the milk to be poured 

 into. Do not put out a pitcher or any other uncovered dish. 



Do Not Allow Milk To Stand Around the House: Keep Milk Covered. 



Careless housewives often spoil milk that is delivered to 

 them in prime condition by letting it stand for a long time on the 

 dining table or in a hot kitchen : under such conditions milk spoils 

 quickly. Keep the milk covered so that it cannot be polluted 

 either by the filthy fly or by dirt falling into it.
