water courses, we find that the results are not entirely satisfac- 

 tory. At certain times of the year vegetation is so dense and the 

 water courses are so sluggish that in some instances it is very 

 difficult to treat known breeding places. We are also handi- 

 capped because of the lack of drainage facilities and insufficient 

 labor to cope with this part of our activities. Due to the fact that 

 boundaries are not clearly defined, and in most cases the owners 

 are non-residents and not amenable to our authority and the cost 

 of fill prohibitive, it remains for the city to eradicate these breed- 

 ing places. Steps have been taken to relieve these conditions in 

 the near future. 



We discontinued the distribution of oil on the ist of Novem- 

 ber, 1 92 1. Later developments have proven to me that oil should 

 have been continued to a later date, as we found numerous breed- 

 ing places in our fresh water swamps as late as November 30th, 

 specimens of which were obtained and placed on exhibit for 

 demonstration purposes in the Grand Central Palace, during the 

 week of November 14th, under the auspices of the Public Health 

 Service. It is therefore obvious why we have determined to 

 prosecute a more vigorous inland campaign. 



For educational purposes the exhibit held at the Grand Central 

 Palace was a wonderful success. Information was solicited and 

 conveyed to visitors from all parts of the United States, Central 

 America, South America and a considerable part of Europe, in 

 relation to mosquito extermination work. Our literature was 

 in such great demand that our supply was exhausted two days 

 before the exhibit closed. As a result there is no doubt that 

 humanity will be greatly benefited and an added impetus given 

 to the movement throughout the entire civilized world. vSubse- 

 quent to the exhibit there had been an increased demand to the 

 department of health for literature on the mosquito, which we 

 are now preparing. This desire for literature applies, in part, to 

 our greater city, the citizens of which are showing an increased 

 interest and desire to co-operate with the department of health in 

 their efTorts to stamp out this insect within the city limits and 

 elsewhere. We have taken the public into our confidence thereby 

 obtaining their good- will and their invaluable co-operation, 

 which must of necessity go hand in hand. In addition, the trans- 

 portation officials and private interests upon whose properties we 

 found considerable breeding, have agreed to do all in their power 

 to further the interests of the department of health in their cam- 

 paign against the mosquito. 



We have conducted an intensive campaign in the public parks 

 and recreation playgrounds with very appreciable results. We
