Of the mosquitos troublesome at the points in question 99 per cent, 

 breed on salt marshes, and fly or are carried by wind to the areas 

 investigated. The salt marsh mosquitos concerned travel on winds 

 of low velocity, 10 miles an hour or less ; of high humidity, 70 per cent, 

 or more ; and of high temperature, about 80° F. The prevailing 

 winds from May to September, especially July and August, come from 

 the south and south-west, and the marshes in these directions are 

 therefore special sources of infestation.
