6 AGRICULTURAL EXPERIMENT STATION. 



required considerable good-natured persistence and tact to get 

 even a hearing-; yet during the first year, when I was working 

 ahnost single handed, the attitude of the press and of the public 

 began to change, and before the end of 1903 practically all the 

 influential newspapers had ceased to ridicule and were giving 

 serious consideration to the matter. At present writing the Press , 

 as a whole and the public generally are no longer antagonistic, 

 and while to many the result aimed at still seems an impossible 

 one, yet they are ready to believe in at least a mitigation of the 

 present conditions. 



During the three years last past I have met with boards of 

 health, with city officials, with physicians and sanitarians and 

 other bodies throughout the State. I have lectured before asso- 

 ciations of many sorts, and I believe that as the result there is 

 at present a much better knowledge of moscjuitoes than was ever 

 had before. 



It must be distinctly understood that all the investigations 

 here recorded were made in New Jersey and that the facts ascer- 

 tained are as they stand in our State. So, too, the suggestions 

 made apply to our own conditions primarily. In most instances 

 they are also of general application ; but it appears from some 

 recorded observations and from information gained in personal 

 converse with other investigators, that under other climatic and 

 geographic conditions there is some, greater or less, modification 

 in habit. I would not insist, therefore, upon the accuracy of my 

 statements as to habits under other conditions than our own, and, 

 of course, a material change in habit might carry with it as a 

 necessity some modification of treatment. 



It is not the intention tO' present here any detailed description 

 of all the stages through which evei-y species passes, nor to make 

 a technical study of all structural and other characters. That 

 feature is in the hands of Dr. L. O. Howard, who is making a 

 thorough scientific study of all the species found in the United 

 States for the Carnegie Institute and who has the assistance of 

 specialists from the staff of the Entomological Divisions of the 

 U. S. Department of Agriculture and the U. S. National Museum. 



It is intended to present only such a characterization as will 

 enable the willing student to recognize all our New Jersey species 

 in the larval and adult stages by means of such differences in 

 structure and appearance as have been found to exist. To do 

 more would unduly enlarge this report without adding to its 

 usefulness for the purpose for which the investigation was made.
