from the fly pest. It is women who have to wage a constant war 

 to protect the food in the home and the infiints in the cradles. 

 Women's organisations can do much to secure the adoption of 

 anti-fly and sanitary measures and in many places they are 

 succeeding in making the community more healthy. The boy- 

 cotting of shopkeepers who do not protect the food they sell or of 

 milk vendors whose premises are breeding grounds for flies is a 

 cogent method of securing reform. 



Citizens' organisations should begin campaigns for clean cities. 

 Such organisations are able to render invaluable service to the 

 health officers by cooperating with them in the locating and sup- 

 pression of the breeding grounds. By lectures, by the distribution 

 of circulars such as the one illustrated herewith (fig. 102) which 

 I prepared four years ago, and of other literature, much good 

 can be done. The press has shown its willingness to assist, and 

 the aid of local newspapers should be enlisted. An excellent and 

 educative cinematograph film illustrating the life-history of the 

 house-fly and its method of spreading disease has been prepared 

 and in my own experience has accomplished splendid work. 



The statement cannot be too often repeated that flies and filth 

 are synonymous terms. In a clean and sanitary community flies 

 will be unable to exist in dangerous numbers and their absence 

 may be taken as a measure of cleanliness. The time is coming 

 when men will realise that it is easier to prevent disease than to 

 cure it and less costly in terms of human lives.
