PART IV. 

 Local Problems and Surveys. 



EXPLANATORY. 



It is manifestly impossible to report within reasonable limits 

 upon all the areas that were investigated during- the three seasons 

 through which this study extended. Whenever a request was 

 received from any municipality, improvement association or even 

 an individual, concerning- any specific area, it was usually heeded 

 and information was furnished covering the conditions. In most 

 cases the common house mosquito was in fault and the remedy 

 easy; to report such cases would add nothing to the general 

 knowledge. 



It is intended, however, to cover those well defined larger 

 areas which were more thoroughly explored and whose treat- 

 ment would affect a considerable area or population. It is also 

 intended to demonstrate in this way how small a territory it is 

 really necessary to deal with in some of the areas that had been 

 considered most dangerous. Finally, the intent is to show how 

 extensive our explorations really were and how large a portion of 

 the State was tramped by the collectors and investigators con- 

 nected with this study. 



Examples of work done in specific areas by individuals or 

 asociations not connected with this survey are also given as illus- 

 trations of what may be accomplished by local organizations.

 was done much more thoroughly than elsewhere. First, the
