103. Habit of drinking. While alcohol is harming a 

 man, it makes him feel good, so that he does not think of his 

 danger. At first he drinks only a little, but it seems to make 

 him feel good. After it has gone out of his body, he feels 

 its harmful effects. Then he wants another drink, so as 

 to make himself feel well again. This desire to take alco-

 and cannot be trusted. He is thus very apt to injure 

 others, and even his dearest friends. Every day we read 

 of drunken husbands beating their wives and children. 

 Many a criminal has had to get half drunk before he has 

 dared to commit his crime. Thus many have to suffer 

 because one man wants to have the pleasure of drinking. 

 Strong drink harms not only the drinker, but also his 

 friends and neighbors. So it is right to make laws which 

 shall keep a man from selling alcohol and strong drink. 

 School children are now learning how bad alcohol is, and

105. Form of alcohol in drinks. The effects of alcohol 

 are the same in whatever form it is taken. Pure alcohol 

 has an unpleasant taste and burns the mouth of even an 

 old drinker. So in drinks it is always mixed with water.
