turn with Paris green, and apply in the same way. 

 When my buckthorn hedges are infested, I take the 

 shears and cut off the young shoots and burn them 

 up. The damage is worst of all on sweet cherries. 

 Here it is sometimes so great that I go over young 

 trees and pick off infested leaves and burn them, 

 trusting nature to slowly overcome the damage 

 done by the removal of the foliage. It frequently 

 happens that new growth will soon take place, and 

 that will not be infected. It needs a whole volume 

 to discuss these little, but most destructive, crea- 

 tures. The woolly aphis is a curious insect, and is 

 often mistaken for a bit of cotton or vegetable floss 

 floating in the air. It is a blistering pest when it 

 makes its home on the bark of a tree, while another 

 sort that works underground is one of the worst 

 enemies of our berries, and still another of our 

 grapes. The variety that works on raspberry roots 

 creates galls, which soon destroy the vitality of the 

 cane. Our only remedy is to dig up the plants and 

 burn them. 



There is one compensation which comes from 

 some of the aphidse; they deposit a honey dew, 

 from which our bees make a large amount of 

 honey. Nor is this honey an inferior product.
