INSPECTION OF FACTORIES 503 



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

 taken with something else, but be sure of the quality of your ice 

 cream. More than 250 samples of ice cream collected and exam- 

 ined in Washington, D. C, contained from 37,500 to 365,000,000 

 bacteria per cubic centimeter. The condition of ice cream de- 

 pends largely on the sanitary conditions of the place where it was 

 manufactured. Above all, be sure that all the food you eat is clean. 

 Stands on the street, exposed to dust and germs, often have for 

 sale food that is 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. 



Project. Get help from your teacher or the local board of health 

 in testing the purity of ice cream and other foods sold from stands 

 outside the school. Test foods in your own school cafeteria at the 

 same time as a control to see which conditions are better. 



Self-Testing Exercise 



Check the correct statements for your workbook : 



T. F. 1. Schools are often dusty because of the movement of chil- 

 dren through the halls. 



T. F. 2. Feather dusters are better than wet cloths because the 

 cloths stain the woodwork. 



T. F. 3. Luncheons should be tasty as well as clean and well-balanced. 



T. F. 4. Ice cream is always a safe food because freezing kills 

 bacteria. 



T. F. 5. If foods are exposed, the sunlight will kill the bacteria. 



PROBLEM XIII. HOW MAY WE HELP IMPROVE CONDITIONS 

 IN OUR COMMUNITY? 



Inspection of factories and public buildings. It is the duty of a 

 city to inspect the condition of all public buildings, especially of 

 factories. Certain trades where dirt or poisonous fumes are given 

 off are dangerous to health, hence care for the workers becomes 

 a necessity. In such places the machinery must be protected 

 by hoods or ventilators to carry off the fumes, and the workmen 

 must be provided with dust and fume masks. Often goggles are 

 provided to protect the eyes from dust or bright light. There
