vals between this time and the young- issuing from

the young ones attain animation, they work their 
way out of the shell by perforating round holes, 
and then quit their dungeon in pursuit of a more 
lively and fertile residence. The male has wings, 
and its life is only of a short duration. 
These animals prove very injurious to the 
trees, from perforating- the cortex with their pro- 
bocis, and drawing out the juices from the branches, 
and when the branches are numerously infested, 
the bark becomes confined, for their adhering- so 
closely to the branches naturally prevents a free 
circulation of the sap. 
For their Destruction, — Immediately 
after the fruit is gathered, or about the middle 
to the latter end of August, will be a jiroper time 
to wash the trees well with the Mixture (No. 3) 
as the insect will be more readily destroyed at that 
time than any other, on account of there not 
being as yet any shell formed for their protection. 
The Small Scales may be destroyed as 
on Pears. 
The various Caterpillars infest this tree

I lums, &c. j the same means therefore may be 
used for their destruction. 
Sliould these means not be attended to till
