CLERGY TAKE ACllON 175 



We beg to ask that you will speak to your con- 

 gregations on Sunday, July 80, or at the earliest 

 date thereafter convenient to yourself, in behalf of 

 the work now being carried on by the Health 

 Authorities of the city. 



We ask that you will urge them, whether they 

 believe in the " mosquito theory " or not, that they 

 will give their hearty assistance to the authorities who 

 are attempting to stamp out the mosquito, as at least 

 one source of infection. Urge upon them the patriotic 

 duty of allowing cisterns to be oiled and screened ; 

 cesspools to be treated with disinfectants, etc. 



JMany householders (a small minority, but still 

 enough to work mischief) refuse permission to the 

 oilers and screeners to do the work. This refusal 

 nullifies to a great extent the work accomplished on 

 the premises of willing householders. In previous 

 visitations of the fever we have been fighting in the 

 dark, striking at an unknown enemy coming from a 

 mysterious source. 



The consensus of scientific opinion fixes upon the 

 mosquito as the agent of transmission of the Yellow 

 Fever. 



The enemy therefore is in sight. So far as your 

 power extends, then, we beg of you to use it for the 

 spread of information concerning the mosquito theory, 

 and to use your influence with your congregations 

 to hold up the hands of the constituted Health 

 Authorities. 



This office will gladly receive suggestions and will 

 give all possible assistance to the Ward Organisations. 



It is proposed to have two cleaning-up days, 

 by proclamation of the Mayor, although this has not 

 at this writing been definitely decided.
