FIGHT THE GOBLIN MOTH

against the codiin moth which the board
considers "the worst pest ever introduced
into the state" In Il circular Just issued
the board sets forth the necessity for
immediate action. Here is a sentiment
that orchardis,s will appreciate:
Tho time has arrived when every
person having an orchard should be the
owner OF force pump with spray
uczzle especially adapted to the work of
spraying trees. Where one person has
not sufficient use fer Pump to justify
him in buying one FOR himself ulouc, let
him ioin wi h a few ueislbors aud ct
one that will serve them all. The cost oi
the material and the time required
in applying it is small. London purple
or Paris green costs but % cents per
pound in small quantities, aud pumps all
complete, ready for use, can be had from
Sl4 to S3i each, according to size aud
capacity for work.
|, is the desire of the board to 10 all
they can in accomplishing the results
sought in the enactment creating them,
aud to this end bcspcak the co operation
of every person interested in horticulture
in Oregon. The secretary desires t.
secure the name and address Of every
fruit grower in Oregon. He also desires
that all shall write him freely relative to
their experience in combating tAcsc
common enemies OF the orclarlist, for
it is only by an Interchange of cxpcr
fences that the best results can be ot
taincd.
The circular recently issued by the
board is as follows:
The Goblin moth is without question
the insect that wants to be looked after
first, as it is without doubt the worst pest
ever introduced into the state. 1t is
needless TO write at length about the
ravages Of this enemy of the pear, apple
and ounce; those who have suffered
from his acquaintance know him well Il
those who have been SO fortunate as 10
escape his acquaintance will DO we'll to
use the one ounce OF preventive and keep
him out, and so have no need tor the
pound Of cure. 1t is only by eternal
vigilance that Ore2on'a reputation for
producing the "big red apple sound ard
free from worms, ''can be maintained"
We therefore appeal not only to that
first law Of nature, 'sclf-prescrva,icp,"
but to that nobler one that strs the
heart and prompts to nobler deeds that
the entire state may be benefited thereby.
REMEDIES AGAINST THE GOBLIN MOTH.
There arc two modes of. fighting them
generally made use oC-cne is to prevent
the hatching OF the eggs, or the killing
OF the young worm while working into
the fruit; the other is the catching the
worm in traps as it is escaping from the
fruit, or by having the fruit eaten by
hogs as soon as it drops from the tree
and before the worm escapes. The first
mode is no doubt the most successful.
and is also the least expensive. This is
accomplished by spraying the trees with
London purple or Paris green, using one
pound Of either to 100 gallons of water.
Paris green is compound of arsenic aud
copper. 1t is far more powerful poison
than arsenic alone, and is not soluble in
water, hence it will remaia much longer
on the trees. London purple is another
arsenical compound. II is the residue
from the manufacture Of nnlline dye, and
contains lime, arscnious acid aud car
bonaceous matter. 1t is soluble, more
adhesive and less poisonous than
Paris green, and therefore is to be pre-
ferred. 1t is better to wet the powder
thoroughly and make paste before
putting it into the vessel Of water that it
may not form Jumps. The spray is
caused by forcing the liquid, by means of
a forcepump, through 6nc perforated
nozzle, made especially tor the purpose.
The finer it is the less liquid will be
required. The important thing is 70
scatter the spray on all the fruit.
WHEN TO SPRAY.
The codlin moth, soon after the fruit
sets lays her eggs upon the calys end Of
the young fruit. The grub as soon us
hatched eats it's way into the center Of
the young fiuit, aud there, growing with
it's growth, works its mischief. In its
early state the young fruit is erect, its
cslyx upward. and the least particle OF
poisoned water falling upon it is sufficient
to destroy the young worm when it at
tempts to cat its way into the fruit !;
therefore, the best and most opportune
time Tor spraying the trees is soon alter
the fruit is set, and when it is about the
