| woody aphis at the head of fruit pests in
Oregon. 1t is a small insect, covered with
white woody substance. They infest both
root and branch of the apple tree. The fol-
lowing remedy is reeomendedi "Four
| pounds of rosin: three pounds of sal soda,
water to make four and one-half gallons;
| dissolve the sal soda in few pints of water;

The apple tree borer is aAbeetle which is
cut at night, deposits eggs in the bark and
fork of the tree. The grubs bore into the
wood The natural enemies of these insects
are the birds of the woodpecker tribe.
Artificial remedies are to find the cast of
the Larvae, and kill them by piercing with a
flexible WIRE FERMENTATION is, however, the
only sure remedy. Keep the base of every
tree clear of weeds and trash, and apply a
solusion of soft soap reduced to the consist
eace of thick paint by the addition of d
strong solution of washing soda in water.
This, if applied to the bark of the tree,
especially about the base or collar, and
thence up the trunk and over the larger
branches, will dry in few hours and form
tenacious coating not easily dissolved by
rain. This soft soap solution should be ap-
piled in May, and second tim. the latter
part of June.
The apple-tr caterpillar can be destroy
ed by hunting the egg-clusters and destroy
ing them in the winter by trickling kerso-
cleaned of them by the use of the London
purple spray as used for the destruction of
the Goblin moth, or three spoonsful of Ore
garth Insecticide dissolved i'll pailful of
water, and the trees sprayed with this solu-
tion. During the day they are so constantly
on the move, that tree thoroughly cleans
ed from them i'll the morning may be crowd
ed again before night, so, to avoid this,
lasten strips of cotton batting four inches
wide about the trunk of the tree by means
of string tied tight in the middle.
For black spot or fungus Oh the apple and
pear fruit, this solution is advised. taking
care not to injure the foliage. 1t is app lied
with spray pumps:
Dissolve one pound of sulphate of copper
tblue vitrlol) in one gallon of hot water.
% this ISOLATION add liquid ammonia, little
at time, until all the copper is precpitated
The liquid is then turbid and blue in color
Add two or three gallons of water and let it
stand and settle. Then pour off the clear
liquid, which contains suiphate of ammonia
the compound which causes the burning
of the larvas-then pour upon the precipi-
tate left i'll the vessel just enough liquid
ammonia to dissolve it; the result is clear
liquid of deep blue color. When required
for use dilute to twenty two gallons.
For the pear and cherry tree slug, which
! destroys the leaves in June and August, this
remedy is suggested;
London purple or Paris green mixed with
water in the proporatlon of enc ounce to six
gallons, applied to the foliage with syringe
or spray pump promptly destroys this slug.
Fresh air stacked lime, sand, ashes, or road
dust, busted on the foliags is said to he an
etlicient remedy, but these latter are unsatis-
factory measures and usually of little value.
The currant worm strips the currant and
gooseberry bushes of their leaves and the
young fruit dies. Paris green Or London
purple, or white hellebore, one tablespoon
fu! dissolved in pint of water applied with
watering pot. is recommend ed.
The San Jose c.le destroys fruit, orna-
mental or forest trees. Imported on fruit
trees brought from California. These are
the ingredients for a barrel of the remedy
used as !. sinser wash:
Twenty-Five pounds of lime (nnslacked);
twenty pounds of sulphur; fifteen pounds of
salt; sixty gallons Of water. To mix the
above, take ten pounds of lime, twenty
pounds of sulphur, and twenty gallons of
water. Boil until the sulphur is thoroughly
dissolved. Take the remainder-ffteen
pounds of lime and fifteen pounds of salt
slack, and add enough water to make the
whole sixty gallons. Strain and spray on
the trees milk warm or warmer. This can
be applied when the foliage is off tile tree,
and will have no njurious effect on the
fruit hu,is or tre ma
