CHAPTER VII 



KNOWLEDGE is power only when it is turned to practical 

 use, and it, therefore, behoves us to turn our knowledge 

 of the fly and its habits to practical account and declare 

 war upon this terrible insect, which is sowing the seeds of 

 disease and death broadcast amongst us and our domestic 

 animals. Unfurl your standard, rally your forces, and fight 

 as one man. Yes, fight on, and continue your campaign 

 every summer season until the enemy is subdued. 



Then great watchfulness will be necessary, for this is 

 an enemy which is capable of breeding a vast army in an 

 incredibly short time. 



It is a moral duty for every householder to keep his 

 dwelling free from flies, for sooner or later disease will 

 ravage his family, and the families of his neighbours. 



The storekeeper by neglecting to keep his shop free from 

 flies, or who refuses to screen his goods from them, is 

 morally responsible for any sickness and deaths amongst 

 his customers, who may contract disease through his fly- 

 infected goods. 



So, too, the governing bodies of hotels, schools, nursing 

 homes, hospitals, villages, towns and cities are morally 

 responsible for sickness, distress, financial loss and pre- 

 mature deaths of the people if they do not avail themselves 

 of the knowledge they now possess in regard to the disease- 

 spreading power of the House Fly.
