MAN'S IMPROVEMENT OF HIS ENVIRONMENT 377 



Use of Ice. Food should be properly cared for at all times, but 

 especially during the summer. Iceboxes are a necessity, especially 

 where children live, in order to keep milk fresh. A dirty icebox 

 is almost as bad as none at all, because food will decay or take on 

 unpleasant odors from other foods. 



Disposal of Wastes. In city houses the disposal of human 

 wastes is provided for by 

 a city system of sewers. 

 The wastes from the kit- 

 chen, the garbage, should 

 be disposed of each day. 

 The garbage pail should 

 be frequently sterilized by 

 rinsing it with boiling 

 water. Plenty of lye or 

 soap should be used. Re- 

 member that flies frequent 

 the uncovered garbage 

 pail, and that they may 

 next walk on your food. 

 Collection and disposal of 

 garbage is the work of the 

 municipality. 



School Surroundings. 

 How to Improve Them. 

 From five to six hours a 

 day for forty weeks is 

 spent by the average boy 



or girl in the schoolroom. It is part of our environment and should 

 therefore be considered as worthy of our care. Not only should 

 a schoolroom be attractive, but it should be clean and sanitary. 

 City schools, because of their locations, of the sometimes poor jani- 

 torial service, and especially because of the selfishness and care- 

 lessness of children who use them, may be very dirty and unsani- 

 tary. Dirt and dust breed and carry bacteria. Plate cultures 

 show greatly increased numbers of bacteria to be in the air when 

 pupils are moving about, for then dust, bearing bacteria, is stirred up 



The wrong and the right kind of garbage cans.
