THE PINE-APPLE. 49 



The most effectual remedy for all these insects is 

 to mix four wine-glassfuls of paraffin -oil with four 

 gallons of water, keep the whole well mixed, and 

 apply it to the plants with a common garden syringe. 

 Allow each plant to stand a few minutes, and then 

 syringe freely with clean water. This destroys the 

 insects without injuring the plants.
