Inspection revealed the fact that we had within our territory 

 over i,200i cisterns. While the number of them found breeding 

 was small, those that were abandoned as a water supply were 

 found in such condition that made ideal iplaces for breeding mo- 

 squitoes. They are located on property that lacks modern im- 

 provements and occupied by owners and tenants whose idea of 

 sanitary conditions would not conform with the State Sanitary 

 Code. 



I have expended considerable time and patience trying to 

 persuade owners of this class of property to remedy such condi- 

 tions on their own premises, but nothing less than a complaint 

 in the Police Court would bring any results. 



The following are factors which make a compleie eradication 

 of mosquito breeding in cities almost unattainable. Lack of 

 interest and co-operation on the part of the residents, the attitude 

 of indifference as to conditions surrounding their homes and 

 places of business is a feature that makes absolute success in this 

 work almost an impossibility. Street catch-basins are a source 

 of breeding that cannot be controlled except by temporary oiling. 

 The breeding in catch-basins generally occurs during periods of 

 dry weather, and as a rule, at a time when other parts of the work 

 of extermination are lessened through the drying up of pools 

 and swamps. It is important that this class of breeding be kept 

 under control, if, as was found last season, tha^- the species of 

 A. sylvestris had invaded the catch-basins. This means a broader 

 distribution of mosquito annoyance, as this particular species 

 travels much farther than the home-loving pipiens. Small catch- 

 basins in public parks should not be overlooked during the dry 

 weather seasons, as breeding in them is apt to cause more public 

 comment on mosquito annoyance than in other places. Visitors 

 to our public parks expect to enjoy the pleasure of them without 

 being annoyed with mosquitoes. Within the area of our beautiful 

 parks are to be found swamps and stagnant pools that are con- 

 tinuous mosquito breeders during the summer months. This 

 feature of *park work does not seem tO' be considered of any im- 

 portance by those in charge of public parks, neither in the interest 

 of the visitor to the parks nor to the residents adjoining the park
