THE HOUSE FLY 65 



man and his animals can be prevented by destroying the 

 fly which carries the infection. Yet withal, the governing 

 bodies of towns and villages make little or no effort to save 

 the people under their charge from the sickness, financial 

 loss, mental and physical anguish, and premature death 

 due to House Flies. A few illnesses which afflict humanity 

 are caused by morbid changes within the body, such as 

 rheumatism, gout, neuritis, &c., but the majority are 

 caused by the infection of the body from without by tiny 

 organisms known as microbes or bacteria. The House 

 Fly is the principal carrier of these microbes to us, and, 

 like a flock of sheep ravaged by some carnivorous beast, 

 we await our doom. 



If men desire to develop their brains, they must use 

 them. The moment a man lapses into mental and physical 

 indolence he begins to degenerate, and Nature, having no 

 further use for him, seeks to kill him off. Thus whole 

 nations of men have been swept off the face of the earth. 



In communities of men where the governing bodies are in- 

 different, or where the measures adopted are not of the most 

 thorough and effective nature, or in small communities 

 and isolated dwellings where there is no governing body, it is 

 essential for each householder to take the matter in hand. 



The campaign should be started in the early spring in 

 order to destroy as many flies as possible. 



A comparatively small number of flies survive the winter, 

 therefore it is an easy matter to stamp them out, or nearly 

 so, before they begin breeding operations. 



Remember, a single female fly can, under favourable 

 conditions, be the parent of about 7,000,000,000,000 flies 

 in a season.
