 for the same purpose. 



Of all the insect-tribe, the Acari are the most

 in Pine-stoves ; indeed, they often prove fatal to 

 them. 



Before I had discovered an effectual method of 

 destroying them, it used to grieve me much to see 

 the Vines often in a languishing state from these 

 insects ; and as I still frequently see Vines growing 

 in Fine-stoves in the same predicament, I flatter
