iai<Ulle of June, some continue to issue forth Iroin 
the ejjg-. Each fiimily, as they are brought into 
existence, set off from the door of their family 
abode, in various directions, in ])ursuit of estab- 
lishments of their own choice. 
These insects, when numerous, give the tree 
a rusty dead-like appearance. The tree is not 
only retarded in its growth, by the insect absorbing 
the sap, but materially injured for want of a free 
circulation of it, which is prevented from their 
vast numbers firndy cemented to the tree. In 
this way I have seen trees, not only of Pears, but 
of Apples, Plums, and others, so completely stag- 
nated as to scarcely make any growth, and the 
fruit produced not half its proper size, much crip- 
pled, and in flavour worth nothing. 
For their Destruction. — The Mixture 
(No. 3,) must be applied well with a painter’s 
brush all over the tree, at least twice, the first time 
not later than the beginning of June, and the 
second time in the middle or not later than the 
latter end of June. There should not be much 
variation in the time here specified, as there is at 
least a month difference in the time of the first 
and the last issuing forth, and therefore there is a 
danger of the shell of the first becoming too hard 
for the Mixture to penetrate sufficiently by the 
time the latter ones have quitted the ova. 
At the winter pruning, all the refuse branches 
should be gathered and burned, and to do it more 
cfl’ectually, a cloth or mat should be spreael to
