The remedy found 70 be most Satisfactory

takes place the mixture Will be of
an amber color. Next place in O cask

phur in the boiler and boil for half an
hour longer, when the necessary amount
of water to make sixty gallons should be
added.
When using II should be frequently and
we'll stirred.
For large orchards and where steam
boilers can be had these ingredients can be
compounded By steam TO good advantage.
The method - TO attach the steam pipes
10 large yats in which are placed. in pro-
portion. fifty pounds lime, 100 pounds
sulphur and five pounds concentrated lye,
then add 100 gallons water (hot water
preserredl turn on the steam and boil
from two to three hours, until contents
ara well dissolved, Carefully slake 80
pounds of lime. adding this and seventy
five pounds of salt to the large vat, keep
up the steam and boil for half an hour
longer, then add water to make 300 gall
Ions. The residue should be very slight
and the mixture have the appearance of q
chemical solution.
Ii would be we'll to apply this wash to
oil fruit trees growing in the orchards of
this state. Where there are only few
trees the wash can be applied by means OF
a brush but otherwise with q spray
pump. The solution made by the
combination OF these ingredients Is re-
garded as beneficial TO the soil. hence the
value of the portion falling on the ground
Wneu spraying Is not t0st.
The remedy has been applied last winter
on certain apple trees in this state badly
infested with the woolly aphis. and very
fcs Of these pests could be found on those
trees this summer.
One of the most extensive prune grow
ers In Clarke county has stated hrs inten-
ton of spraying his entire prune orchard
with this solution.
As an extra precaution against intro
ducing new pests into the orchard. il is
recommended that q mixture of this solu-
ton Is placed in vat in which the trunks
aud branches OF young trees can be dipped
before planting. Although nursery stock
may have been disinfeeted, it will do no
harm TO apply this treatment.
For those who are applying OF placing
their orders for their own planting
directly TO nurseries outside this state IL is
suggested as safeguard that this remedy
be applied III there is any appearance OF
wooliy aphis on apple trees. the roots ofthe
apple trees must be dipped in solution
made according to the following formula
