when failure to obtain successful results was rendered futile by 

 inefficient work and untrained field, workers. 



The element of cost again was considered discouragingly great 

 to bear alone for the individual in a private venture where there 

 was little in the way of financial gain. 



Other causes obvious to those of you engaged in this work also 

 tended to discourage these isolated efforts to carry on mosquito sup- 

 pression in these last mentioned cities and towns. 



In conclusion, I wish to state that the citizens of Massachusetts 

 are fully alive to the need of caring for the mosquito nuisance 

 throughout the state, but it seems to me the public regards the prob- 

 lem as a secondary one which may be deferred in order that the 

 money may be expended on more pressing and important problems 

 first. 



In order to overcome this attitude of the public on this matter, it 

 is necessary for us to point out to the business men that the economic 

 values of real estate of natural value have increased one hundred 

 fold wherever land sites for dwellings have been free from the 

 mosquito nuisance, and that money invested for this purpose is 

 money well invested. 



Technical, scientific propaganda in aid of public health does not 

 appeal to the average individual and is of questionable value when 

 so used in anti-mosquito campaigns. It is well to discontinue it as 

 an educational factor except where it directly points out increased 

 monetary returns for the cash to be expended in suppressing the 

 mosquito nuisance. 



The public is willing to gamble desperately their health and their 

 lives against pain, discomforts, disease and the mosquito nuisance, 

 but the public will not gamble their money on social welfare prob- 

 lems except they have a chance to get back double the money on 

 their investments. As a result, we have decided to follow public 

 opinion, and our campaign has been one of taking care of all the 

 small breeding places at the expense of the public treasury, except 

 the larger problems where we have requested the financial co-opera- 

 tion of the people owning the land. 



President Rider: It now gives me great pleasure to introduce 

 Dr. Lipman, of the New Jersey State Experiment Station, who is 

 with us tonight.
