i 34 MALARIA 



Appendix III 



Rules for the Prevention of Malaria. — I. Allow no 

 stagnant water on your premises. Go over every part 

 of your property carefully, fill in or drain every low 

 spot where stagnant water can collect for any length 

 of time. See that there are no barrels, tin cans, or 

 other things holding water, unless they are carefully 

 covered or screened. 



2. The only way in which you can get malaria is 

 by the bite of a certain kind of mosquito. You cannot 

 get malaria from drinking water, bad or marshy air, 

 overripe fruit, stale beer, or in any way except by the 

 bite of a mosquito. The mosquito breeds in stagnant 

 water. Only a very small amount of water is neces- 

 sary to breed many mosquitoes, and it is usually the 

 small, insignificant pools that breed the greatest num- 

 bers, not the big, open ponds of water. 



3. Where you find it impossible to either fill in or 

 drain away water that is stagnant for more than a 

 week, a coating of coal oil once a week will keep the 

 mosquitoes from breeding in that water, but try first 

 to get rid of the water as far as possible. 



4. Clear away all brush, tall grass, and weeds around 

 your house, as these make places for the mosquito to 

 hide in during the heat of the day. Keep things 

 trim and neat.
