brought from some nursery outside OF
the State--thus the necessity of law
requiring nursery stock to be inspect
ed before it is shipped from the nur-
sery Since Mississippi has no law
of this kind, every buyer of fruit trees
should demand that their trees be ac-
companied by a certificate of inspec-
ton from competent entomologist
to the effect that they are free from
the scale.
The second thing | wish to discuss is
method of combating this insect
in the summer Some fruit growers
are losing their trees this spring from
the effects of the work of this scale,
and unless they do something right
away. more trees will die before Iall.
Summer, however, is not the best time
to fight the scale. because 1t is diff
cult to get substance that will Kill
the insects and not hurt the foliage
of the trees. Winter is the best tint
to combat the scale On the other
hand, there are some things that can
be done in summer to hold the scale
in check Perhaps the best substance
for this purpose is an emulsion made
of kerosene oil and soap. 1t may be
made according to the following for
mula:
2 pounds of hard soap.
gallons OF soft water.
gallons of kerosene oil.
Place the soap in the water over a
fire and heat until 1t Is thoroughly dis
solved. Pour the oil into barrel in
which the pump is set, and when the
water and soap are boiling hot, pour
them both into the oil. Pump the
mixture with vigor back into itself for
ten or fifteen minutes, or until the
soap and oil form creamy mixture.
This should then be diluted to 80 gal
Ions and applied with good barrel
spray pump with two leads of hose.

Seneca Falls. N. Y, and the Empire

N Y, are all good pumps for this
work. IL the trees are small, the
emulsion may be applied with a KNAPP
sack sprayer Knapsack sprayers are
also manufactured and sold by all or
the above named companies. One
should use great care and coat all the
branches and trunks with the mixture.
1t would be well to give the trees two
sprayings about thirty days apart.
| The scale can also be very effective
ly checned during the summer by the
use of the me-salt-sulphur wash. This
| is pre-eminently a winter wash, but
can be used with efficiency during the
GUNNER. 1t kills ,.-e foliage, however,
and cannot be applied to the leaves
with a spray pump. 1t is made accord
ing to the following formula.
Is pounds of sulphur
Is pounds of quick lime.
| 5 pounds of salt.
| As gallons of water
The lime should be slaked in three
or four gallons of hot water in ket-
tie holding at least 20 gallons When
the lime is nearly slaked, but before
| it quits boiling. add the fifteen pounds
of sulphur and enough hot water to
make a thin paste of the lime and sui
