different apples is beyond attack. Their
destruction nov means destruction OF
the fruit we would save. The Eggs are
too minute to be sought out and des-
troyed ever were such a step practic-
able.
But the young worm takes for its first
meal q small part of the outside of the
Apple. Let the surface of the fruit be
thoroughly poisoned and the desired
end is gained. The worm is killed be-
fore II enteRs the fruit.
Thus we have two lines OF. treatment
which may be followed. The worm
may be killed in its incipiency, or after its
work of destruction is over and it is
sleeping in its silken cocoon. The read
er will note the advantages of one
method over those of the other.
At this season many COO may be
destroyed by scraping the rough bark
from the trunks of the trees and clear
ing all refuse from under the trees.
Let all this be burned. Bands of cloth
may be placed about the trunk = foot
or moro above the ground. The worms
will resort to the folds of these. By
June first these may be dipped in hot
water and again placed about the trees,
the process to be repeated at intervals
later. Thus your own and your neigh
boris fruit is being protected from many
future moths which you destroy in the
cocoon. However this is only after your
own fruit has been injured.
POISONING
Is accomplished by spraying on the fruit
either of the arsenal poisons, London
purple or Paris green. These are used
in water mixture (they will not dissolve
and form a solution) one pound of Lon
don purple to 200 gallons OF water, or
n pound of Paris green to $50 gallons
OF water. During the application pro-
cess these mixtures must be kept we'll
agitated, otherwise the first used is too
weak and the last too strong. The
tendency of these compounds is to de-
stroy foliage, causing it to turn brown
and fall. This must not be permitted
to occur to any great extent.
As to danger in use of these poisons
there Is absolutely none. The winds,
possible rains, and especially the change
in the skin Of fruit, remove every trace
of poison by the time the fruit is ripe.
Repeated chemical analysis have demon
strated that the amount OF poisons ad-
herring to the fruit is perfectly harmless.
The first spraying should be done at
the time the blossoms are falling. This
is in time to catch the first eggs and
sufficiently late to save the bees from
poisoning. A second application ten
days after the first, and again at sx and
eight weeks after the first should result
in saving almost all Of the fruit.
SPRAYING APPARATUS.
The essentials here are: Firstly, a
force pump that will throw a ccntin-
uous btrcdih, WHICH, ii u~nODStruCCeO,
will extend far above the ~tree-tops.
Secondly, a nozel, which, without des-
troying the force Of the pump, resolves
the stream into . fine mist that will
penetrate very hidden nook of the tree.
Thirdly, these two are to be connected
by a light hose long enough to permit
the nozzel being held by meanso Of a light
pole among the branches. The forego-
ing statements relative to the theory OF
this treatment show the necessity OF
thorough work performed at the right
time. +. H. HMLMAN,
