(5). When we have cleared as many houses as we deter- 

 mine to deal with, we clear them over again and again. 



(6). We fill up or drain away all the pools, ditches, old 

 wells, and puddles we can especially those which contain 

 most larvae. 



(7). Such pools as cannot be filled up or drained are 

 deepened and cleared of weeds, if they contain larvae. 



(8). Streams and water courses which possess larvae are 

 " trained." 



(9). Where we can do nothing else we destroy the larvae 

 periodically with oil, or by brushing them out with brooms, 

 or by other means. 



(10). We endeavour to interest our neighbours in the 

 work, and to educate the town into maintaining a special 

 gang of men for the purpose of keeping the streets and 

 gardens absolutely free of stagnant, mosquito-bearing 

 water. 



Ip. Motto : Our motto should be one which I think 

 will shortly become the first law of tropical sanitation, 

 namely 



No Stagnant Water.
