distance movements. Ordinarily the flight in such cases goes 

 with the slow-moving warm, damp wind, but modifications in 

 direction of flight may be due to mountain ridges and possibly 

 other factors not at present recognized.

The facts just set forth show clearly that flights of salt- 

 marsh, fresh-water swamp, malarial and house mosquitoes may 

 seriously interfere with the project of keeping a specified locality 

 free from mosquitoes, and indicate that plans and estimates for 

 practical control work must be based on something more than a 

 study of the mosquito-breeding places within a specified area — 

 must include an analysis of the mosquitoes on the wing through- 

 out the said locality for at least one summer season. They show 

 further that the practical work of control must be accompanied 

 by a thorough knowledge of the adult mosquitoes that are abroad 

 in order that the trouble due to local breeding may be distin- 

 guished from that arising from invasions, and in order further 

 that the sources of the invading pests may be found and elimi- 

 nated. 



President BrinkErhoi^i^ — Are there any remarks or discus- 

 sion of this paper? 



Mr. Reid HowEivi. (Bergen County) — The paper has been a 

 wonderfully interesting one to me, and it leads me to ask the 

 question, to what extent, if any, have the Boy Scouts of the state 

 been interested in the work of mosquito extermination? 



I feel that if the Experiment Station, through its various 

 agencies, could induce the scoutmasters to take up the work of 

 these night collections and have a certain number of their scouts 

 provided with the cyanide bottles, the boys themselves would 

 find it of great interest. They might be properly trained by the 

 Experiment Station, either directly or through the scoutmasters. 

 If no other results grew out of it, at least the small boy would 

 talk about it to his parents.
