THE EDUCATIONAL FACTOR

added impetus and adds to his efficiency in the field. 

 Here the more detailed habits of the individual insect 

 can be observed. 



One of the most important factors in our work is 

 that accomplished with and through the school children. 

 The school children are visited in the classroom and 

 the story of the mosquito 

 wriggler is told, — how 

 the mosquito carries dis- 

 ease and how to prevent 

 it. Demonstrations with 

 the living wrigglers can 

 easily be made. Inter- 

 esting essays are then 

 written by the children 

 and the best may be pub- 

 lished in the local paper, 

 all of which stimulates 

 interest and gives the 

 children a grasp on practical subjects. The lessons 

 (Figs. 32, 33, 34, 35) learned at this time will be 

 applied at once, and a generation of citizens is reared 

 with some knowledge of practical hygiene. 



The use of a mosquito pin or button (Fig. 36) has 

 resulted in much good. On answering some simple 

 question on mosquitoes correctly, or after putting oil 

 on a pool of water, the child receives such a pin from 

 the inspector as a reward of merit.

 of merit. School children were given a pin 

 when some small service was rendered.
