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

 fested by mosquitoes, search for the larv* should be 

 made in the house or near it, particvilarly 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

 yards from his house was a pool that m Mr. bperry s 

 opinion produced all the mosquitoes that were such a 

 troublesome pest and drove hundreds away from Ins place. 

 Mr. Sperry is a close observer of mosquitoes and has 

 studied them for years. . . ,• i 



Dr W Stiles, of AVashington, however, is mclmeil

 cottage on the New Jersey coast, that mosquitoes bother 

 his family only after land breez.^s have cnt.nued for sev-
