2. Impure water is very dangerous, for it may contain germs 

 that cause the most dreaded diseases known to man, as cholera, 

 typhoid fever, etc. 



3. Boiling is the only safe way to purify water, because no 

 other means can remove or destroy the disease germs. Filters 

 have some value. 



4. The ice that forms on stagnant ponds, lakes, and rivers, 

 whose waters are unfit to drink, should not be used for drinking 

 purposes, because it is just as impure as the water upon which 

 it forms. Freezing does not kill disease germs. 



5. Next to water, milk is the most wholesome drink, and it 

 will be used more generally as we learn more of its value. Im- 

 pure milk, however, is very dangerous. 



6. Tea and coffee contain poisons that act as stimulants 

 upon the nerves, and a young person in good health does not 

 need to use either. We are better off if we let them alone. 



7. The yeast plant feeds upon the sugar of vegetables and 

 fruits and slowly breaks it up into carbon dioxid and alcohol. 

 The carbon dioxid is a gas and escapes, but the alcohol re- 

 mains in the liquid and gives it a strong biting taste. Yeast 

 and other things that act in the same way are called ferments. 



8. Wines, beers, and spirits are the common varieties of 

 beverages that contain alcohol. 



9. Alcohol produces harmful effects upon the body of a 

 growing boy or girl and therefore cannot be classed among 

 foods or wholesome drinks. 



10. The youth who takes alcohol in any form finds that he 

 needs a constantly increasing quantity to satisfy his abnormal 

 appetite. 



1 1 . Nicotine of tobacco has a harmful effect upon the brain, 

 heart, stomach, and other organs of the body. Its effect is 

 most marked upon the young.
