House-Flies or Typhoid-Flies 71 



Of course only a small per cent of the flies that 

 visit our food in the dairies or market places or 

 kitchens actually carry dangerous diseases, but they 

 are all bred in filth and it is not possible without 

 careful experiments or laboratory analysis to de- 

 termine whether any of the germs among the mil- 

 lions that are on their bodies are dangerous or not. 

 The chances that they may be are too great. The 

 only safe way is to banish them all or to see that 

 all of our food is protected from them. 



FIGHTING FLIES 



Screens and sticky fly-paper have their places 

 and give some little relief in a well-kept house. 

 But of what use is it to protect your food after it 

 has entered your home if in the stores, in the 

 market place, in the dairy barn, or dairy wagon, 

 in the grocers' and butchers' cart, it has been ex- 

 posed to contamination by hundreds of flies that 

 have visited it. 



The problem is a larger one than keeping the 

 house free from flies; larger but not more difficult, 

 for the remedy is simple, effective, practicable and 

 inexpensive. Destroy their breeding-places and 

 you will have no flies. As the flies breed prin- 

 cipally in manure the first remedial measure is to 

 see that all manure is removed from the barn-yard
