tlestructive complaint. The Ribstoiie Pippin, a 
well known favourite Apple, often falls a victim to 
it. There are others firm or hard wooded kinds of 
Apples annoyed with it, but seldom the Codling 
kind. The Jai’gonel may be said to be the most 
liable to the disease of the Pear kind. It gene- 
rally commences at a decayed bud, spur, or 
branch, and sometimes in the trunk and thicker 
branches, where there are no buds or spurs, and

apparently owing to its being too contracted. It 
appears at first about the spur and bud with only 
a smallish brown spot, but gradually decays to a 
considerable extent. Its course often spreads 
round the whole of some branches and stems, so that 
the sap is void of a passage, and, as a matter of 
course, the upper pait dies. 
It is not to be supposed that all the rough, 
rusty appearance we observe so often on the trunks 
and branches of various kinds of trees is connected 
with this disease. The complaint in question 
is both external and internal, so as not only to 
destroy the cuticle, but the woody part also. 
There are several opinions as to the cause 
of the Canker, but the mystery appears too much 
for any one to clearly unfold. I am inclined to 
believe that cold wet summers, and severe win- 
ters, and also strong wet soil, are productive of 
the complaint. If we notice the few late dry 
summers, we shall find that fruit trees, that were 
previously much infested, have scarcely exhibited
