52 THE BEGINNING OF THE ANTI-FLY CAMPAIGN 



likely breeding-places of flies in the town or village to 

 be dealt with. If the health officer is interested he 

 can readily find these out. He should obtain a list 

 of all the stables in the town. Every carriage is 

 licensed, and perhaps the knowledge of this fact will 

 enable a complete list of stables within the urban 

 district to be drawn up. These are the first steps. 



Next, one of the sanitary inspectors should be in-

 distinctive mark against those in which he finds the 

 fly-maggots. This should be done, if possible, during 

 the summer, for the warm weather is the chief fly- 

 breeding season. --It will take him some time a period 

 varying' with his energy, and the size of the town, 

 village, or district to be dealt with. But if necessary 

 two or more sanitary inspectors can be told off for 

 the job. 



As soon as the fly-map is ready and complete the 

 person directing the campaign can draw up his report. 

 He is in possession of the figures of the infant mortality, 

 the incidence of typhoid fever, the prevalence of tuber- 

 culosis, and now he knows the chief breeding-places of 

 the flies which may convey these diseases. He has the 

 facts at His fingers' ends. The report should be short 

 and concise, clear -and lucid, and technical terms must 

 be avoided. ' It should be presented to the local district 

 council which has charge of the sanitary affairs of the 

 town, and this council should be asked to consider the
