about when the tree has shed its bloom, or a little 
after this time, it will be of service to gently press 
with the hand all the leaves that are infested, 
which will be known by being drawn or rolled up, 
to destroy the inhabitants, which may be done so as 
not to injure the leaves much, if it is performed with 
cai'e. The last-mentioned mixture can only be 
applied with any propriety for the destruction of the 
Caterpillars last described, just before the bloom 
expands, and immediately after the fruit is set. 
The operation in the above cases should be re- 
sorted to twice in an hour or two ; the first time 
need not be given over strong, as it is principally 
intended to compel the inmate to let loose its 
protection, to afford a better opportunity for the 
second application. The operation is by hand as 
above, and care must be taken to gather out 
among the clusters all the refuse bloom which 
serves for a concealment to them, and the removal 
of which will also generally include the Cater- 
pillar. This may be done to great benefit, to wall, 
espalier, or dwarf trees, and an active person or 
boy may go over a good many trees in one day.
