cause mosquito reduction is only in its infancy, and 

 it is important that it should be instituted everywhere 

 practicable. This can only be brought about by 

 placing before the notice of the public its possibilities 

 and the methods to be employed. This is the age of 

 advertisement, and advertisement has become neces- 

 sary if any new project is to succeed, or become 

 generally known. Advertisement for such a cause is 

 surely justifiable. Publish frequently, but let the 

 publication be accurate then others can learn from 

 the experience gained. 



It may be finally repeated that this work can be 

 carried out not only by doctors alone, but by all 

 persons who have the welfare of the community at 

 heart. A scientific training is not absolutely essen- 

 tial for the accomplishment of mosquito reduction. 

 Local Health Departments are the best organisers for 

 anti-mosquito measures, but any really interested 

 and responsible person in a town or village can do it 

 if the lines laid down here are followed. 



Lastly, it must be clearly understood that it is 

 not possible to exterminate mosquitos in a given town, 

 or even part of a town ; it is only possible to reduce 

 the numbers of gnats. Mosquitos are very local in 

 their habits and do not fly far, as already emphasised 

 the fact is a most important one. At Port Said 

 one part of the town was cleared first, while another 

 remained untouched. The mosquito nets were 

 largely dispensed with in the cleared district, but the 

 insects continued as numerous as ever in the uncleared 

 quarter ; only one street separated the two portions.
