MAN, THE FLY'S GREATEST ENEMY 43 



successful wars, this one must be conducted with 

 intelligence. For centuries past we have endured flies 

 and the disease depredations caused by them. But 

 now we are beginning to realise their danger and how 

 to fight that danger ; and in civilised countries, at all 

 events, the future must show the downfall of the fly ; 

 its days are numbered in human communities. How 

 long flies will be admitted to our houses is a question 

 of knowledge and education ; and these are swayed by 

 advertisement. The danger of flies must be realised 

 by all and sundry, and then the danger will be removed. 

 As stated before, until the public understands that the 

 house-fly is a dangerous pest which can be prevented, 

 little or nothing will be done to institute that preven- 

 tion. As soon as every one begins to talk about it 

 something will be done and that quickly. Let it be 

 realised that we cannot hope to kill sufficient numbers 

 of these flying insects to seriously aiFect their total 

 population even in the coldest weather. Therefore 

 all measures must be directed to the destruction of the 

 crawling larvae when they are congregated together. 

 That is the chance which Nature has given human 

 beings to rid themselves of a pest, and the diseases 

 which are caused by it diseases which are killing them 

 and their children. Take the fly-larvae in the manure- 

 heap and in the stable, in the slum and back-street, and 

 destroy them. There will be fewer flies then, and so 

 many human lives the more. It requires a little 

 thought, a little work and care, some organisation, 

 much perseverance, that is all and our children will 

 live instead of die.
