BACTERIOLOGY OF THE 

 HOUSEHOLD. 



Every housekeeper would like 

 to eliminate dust from her house- 

 hold. " Where does all the dust 

 come from " is an oft-repeated 

 question. When the house is 

 cleaned thoroughly and tightly 

 closed for a time, dust still finds 

 lodgment upon furniture and 

 bric-a-hrac. We cannot get rid 

 of this enemy even out at sea, 

 for there is dust as long as there 

 are people, furnishings and fires. 

 Scientists themselves are unable 

 to get a dust-proof room in which 

 to perform their experiments. 

 Wood, coal, the wear and tear of 

 the house, our bodies and clothing 

 are constant sources of dust. Wind 

 is the agent for scattering it. Dust 

 in itself does not do much harm 

 though it scratches the polished 

 table and the silverware, and if it 

 were eliminated, life would cease 



altogether, for life needs light and ^ig. 41.— Moving the dust and germs 

 ° . from one place to another. How do you 



the rays of light are borne by dtist your shelves!
