after the accomplishment of which she dies. The 
offspring’, after feeding’ till necessai’y to repair to 
its winter quarters, quits the leaves, and conceals 
itself in the earth, or other places of protection, 
through the winter, and ascends the tree at the 
spring, and resumes its attack on the underside 
of the leaves. In process of time, leaves, shoots, 
fruit, and fruit stalks, become in possession of her 
progeny, and I need not add, before they spon- 
taneously give up their possessions, the whole ai’e 
materially injured. 
For their destruction the trees may 
have a good washing at the latter end of Sep- 
tember, before the insects make their exit, with 
the Mixture (No. 7) ; or at the spring, any time 
betwixt the setting of the fruit, and the com- 
mencement of its ripening, the trees may be 
washed with the Mixture (No. 1) ; but imme- 
diately after the fruit is well set would be the most 
proper time for the spring performance. The 
whisk must be used at each operation. 
The Caterpiuuars. — This tree is also at-

cies of Phalosna, those described on the Apple 
tree. The massive groups of bloom buds which 
this tree naturally produces on each spur, afford 
better protection to them than the Apple tree, 
and, when in a dormant state, many will be found 
upon the branches, protected, as well as those 
among the buds, with a coating or vesture of 
their own manufacture, which is roughly cased over 
with particles of leaves and other materials. It is
