at considerable expense or we could not have used them at any time 

 after 6 p. m. 



"This summer we have a fine garden and it is a pleasure to work 

 in it because the mosquitos are practically gone. Last evening we 

 sat out on our lawn from 7 to 10 p. m., and in all that time only one 

 lonesome mosquito showed up. We have had our suppers out in our 

 back yard during this hot weather and feel that at last we are getting 

 100 per cent use of our home investment." 



Many citizens remarked to the writer and to the inspectors that for 

 the first time since they had lived in Minneapolis were they able to 

 spend their evenings on lawns and porches without screens and in 

 comfort. Visitors to the Lake Harriet pavilion, close to an area of 

 large mosquito swamps, were able to enjoy the evening concerts with 

 very much less annoyance than usual from mosquitos, although the 

 pavilion was on the extreme limit of our district. Those who in- 

 dulged in canoeing on Lake of the Isles and Cedar Lake in the evening 

 were also free from the usual pest of mosquitos. One of the best re- 

 sults of the work this past season was the greater attention given to 

 sanitary conditions by the people of South Minneapolis. 



As a demonstration of what can be done in the control of mosquitos 

 under city conditions, the campaign was a marked success. It dem- 

 onstrated what can be done, when the work has been well planned and 

 carefully carried out by good inspectors. Before the summer was 

 very far advanced it was evident that we had chosen one of the most 

 difficult parts of the city in which to carry out the work. The success 

 under such conditions, therefore, shows what could be done over the 

 entire city. A preliminary survey of the city also confirms the opinion 

 that the entire city can be made practically free of mosquitos at small 

 cost, and in addition the reduction of house-flies can be undertaken 

 by the same staff of inspectors. In the eight square miles covered by 

 the inspectors this year, there were found 574 stables, each one with 

 a fly-breeding manure pile, as well as 353 out-door toilets, every one 

 in an unsanitary condition, and a possible source of fly-borne infec- 

 tion. 



With both flies and mosquitos under control many sources of disease 

 would be eliminated, not to mention the fact that expensive screens 

 on windows, doors and porches would be no longer needed. 



Work ended September 1 as funds were getting short and the demon- 

 stration had given sufficiently convincing results. 



The City Health Department has tentatively promised to lend 

 financial as well as moral support the coming year. With a large 

 staff and with house-fly ehmination added, the brigade of inspectors 

 will become an important adjunct to the City Health Department.
