Kerosene and water emulsion, continued. 



proportion of kerosene emitted will depend upon the rela. 

 tive diameters of the two tubes, but it may also be regu- 

 lated by the relative depths of the liquid in their respect- 

 ive founts. A better way would be to use but single 

 fount and to divide this into two parts, one for kerosene 

 and the other for water. This would permit che mouch of 

 the bellows to be brought nearer to +he plant to be 

 atomized.
