198 INSECTS AFFECTING THE ORANGE. 



The rosiilts were excellent ; the solution being foreed into the colonies hrol^ethem 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 meritof 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.
