MAN'S IMPROVEMENT OF HIS ENVIRONMENT 379 



A sensible lunch box, sanitary 

 and compact. 



equipment, and balanced lunches can be obtained at low cost. 



Do not make a lunch entirely from cold food, if hot can be obtained. 



Do not eat only sweets. Ice cream is a good food, if taken with 



something else, but be sure of your ice 



cream. "Hokey pokey" cream, tested 



in a New York school laboratory, 



showed the presence of many more 



colonies of bacteria than good milk 



would show. Above all, be sure the 



food you buy is clean. Stands on the 



street, exposed to dust and germs, 



often sell food far from fit for human 



consumption. 



If you eat your lunch on the street 



near your school, remember not to 



scatter refuse. Paper, bits of lunch, 



and the like scattered on the streets around your school show lack 



of school spirit and lack of civic pride. Let us learn above all 



other things to be good citizens. 



Inspection of Factories, Public Buildings, etc. It is the duty 



of a city to inspect the condition 

 of all public buildings and espe- 

 cially of factories. Inspection 

 should include, first, the super- 

 vision of the work undertaken. 

 Certain trades where grit, dirt, 

 or poison fumes are given off 

 are dangerous to human health, 

 hence care for the workers be- 

 comes a necessity. Factories 

 should also be inspected as to 

 cleanliness, the amount of air 

 space per person employed, 

 ventilation, toilet facilities, and 

 proper fire protection. Tene- 

 ment inspection should be 



thorough and should aim to provide safe and sanitary homes. 



Dust exhausts on grinding wheels protect 

 lungs of the workmen.
