198 INSECTS AFFECTING THE ORANGE. 



The results were excellent ; the solution heing forced into the colonies broke them up, 

 and coming into contact with the insects killed them, the method of working being 

 one man at the pump, another to guide the stream. The apparatus improvised be- 

 ing badly adapted to the purpose is very awkward. The work, although about four 

 times as fast as with the bellows atomizer, is not adequate to the economical require- 

 ments. This method has the merit of no loss by damage to fruit or leaves by the ma- 

 terial used ; the waste, falling on the leaves and branches, will exterminate both scale - 

 insects and rust-mites, these being plentiful, but neglected in the presence of the more 

 pressing necessity of saving the growing crop from destruction by the Mealy-bug.
