TWELVE] OUR RIVALS—THE INSECTS 
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 aphid; they deposit a honey dew, 
from which our bees make a large amount of 
honey. Nor is this honey an inferior product.
