On the Peach Tree Worm, By Dr. Kirtlqnd-
Among the causes Of the Premature decay on the
Peach tree, the depredat!ons of the Peach tree worm
is the principal one.
In the LARvA or grub form, the BODY Of this worn,
is of whish color and its head reddish brown
Us length at maturity Is about hree tJurths of an
inch.
Il commences its destructive career soon oGer II
has Matched from the egg and enters the tree prob
ably through the teuder bark under the stu face of
the soil. From thence, It first works downwaris in
the root until the early part of the ensuing summur
when II directs its course upwards, towards the body
Of the tree BY eycaya ng channel, as it progresses
between the bark and the wood.
Having attained lis full SIZE in the lara or grub
frs; and the middle OF July. At that time il may
be discovered close 10 the trunk of the tree enve op.

until the latter part of July, or the beginning Of Al.

In this condition it is active and vgilanf. conceal

methods IOr Their counierlCtOn. In the instance of
this insect, very simple remedy To prevent It's de-
predatons has been suggested, and | am happy to
say that experience has 10 extent confirmed its
efficacy.
The Egera, in its perfect or winged state, is close
ly allied 10 the moth family. The fact is probably
universally known that aromatic oils of all kinds are
peculiarly offensive TO that family Of insects Every
housewife knows that quantity of camphor turprn-
tine, oil of anyy tobacco, placed IN her drawers
containing wooden cloths, will eiitc,uallv preserve
them from the attacks of the common moth
It's evident that the same plan, under some form,
may be employed 10 repe from the Peach tree, tn
Egera IN ts moth states and It is only in that state
IN which II deposits It's eggs.
Tobacco, sulphur, aud coal ashes have been tried
with partial success-but they are temporary, and
require TO be often replaced.
Tansy and NORWOOD contain large quantities Of
essential OIL which is peculiarly offensive this in
sect; and is found that if the body of the peach
tree be surrounded by half dozen sprout of either
of these vegetables will be perfectly secured against
the approaches of this destructive enemy
They should be planted out in the spring nearly in
contact with the body Of the tree, and as to sur
round it. During the summer they should he cult
vaed and kept free from grass. In this way they
form permanent successful means Of defence
against the insect that has nearly nxterminaed the
peach tree from many sections OF the country.
