3I0SQU1T0ES IN GENERAL 21 



ted near the centre of a city or villag-e is found to be in- 

 fested by mos(initocs, search for the larvae shoukl be 

 made in the house or near it, particularly in cellars or 

 cisterns, in wells, in water-troughs, in sinks and tubs in 

 the yard, and so on. The truth is that people do not take 

 the trouble to make the careful search, and prefer to jump 

 to the conclusion that the mosquitoes have flown in upon 

 them from a distance. Mr. C. A. Sperry, of Chicago, 

 writes that he is perfectly satisfied that mosquitoes are 

 never distributed b}^ the wind. When the wind blows they 

 are always on the ground, clinging to a support. They 

 are seldom, if ever, seen as high as the third flat in the 

 city. He further makes the sug-gestion that the idea that 

 they are conveyed by the wind deters many people from 

 making an eftbrt to rid themselves of the nuisance, which 

 can so easily be accomplished. In one case, at a summer- 

 resort on Long" Island, a man told him that the mosqui- 

 toes came there from New Jersey, while not two hundred 

 yards from his house was a pool that in Mr. Sperry's 

 opinion produced all the mosquitoes that were such a 

 troublesome pest and drove hundreds away from his place. 

 Mr. Sperry is a close observer of mosquitoes and has 

 studied them for years. 



Dr. C W. Stiles, of Washing-ton, however, is inclined 

 to take a somewhat opposite view from Mrs. Aaron. He 

 informs me that it has been his experience, at his summer 

 cottag-e on the New Jersey coast, that mosquitoes bother 

 his family only after land l)reeze-s have continued for sev- 

 eral days. The cottag-e is situated about one-third of a 

 mile away from the woods, toward the sea and within one
