MAN'S IMPROVEMENT OF HIS ENVIRONMENT 383 



Department of Health states that milk sold '' loose " in restaurants, 

 lunch-rooms, soda fountains, and hotels must be pasteurized. 



Care of a City Milk Supply. — Besides caring for milk in its 

 production on the farm, proper transportation facilities must be 

 provided. Much of the milk used in New York City is forty-eight 

 hours old before it reaches the consumer. During shipment it 

 must be kept in refrigerator cars, and during transit to customers it 

 should be iced. Why? All but the highest grade milk should be 

 pasteurized. Why? Milk should be bottled by machinery if 

 possible so as to insure no personal contact ; it should be kept in 

 clean, cool places ; and no milk should be sold by dipping from 

 cans. Why is this a method of dispensing impure milk? 



Care of Milk in the Home. — Finally, milk at home should re- 

 ceive the best of care. It should be kept on ice and in covered 

 bottles, because it readily 

 takes up the odors of other 

 foods. If we are not cer- 

 tain of its purity or keep- 

 ing qualities, it should be 

 pasteurized at home. 

 Why? 



Water Supplies. — One 

 of the greatest assets to 

 the health of a large city 

 is pure water. By pure 

 water we mean water free 

 from all organic impurities, 

 including germs. Water 

 from springs and deep 

 driven wells is the safest 

 water, that from large 

 reservoirs next best, while 

 water that has drainage 

 in it, river water for ex- 

 ample, is very unsafe. 



The waters from deep 

 wells or springs if properly 



New York City is spending 8350,000,000 to 

 have a pure and abundant water supply. 

 This is the tunnel which will bring the 

 water from the Catskill Mountains to New 

 York City.
