Bordeaux Mixture. For leaf blight
and mildew in Pear, Plum, Apple, and
black rot in the Grape, etc: Add three
pounds of sulphate of copper to three
gallons of water; in another vessel,
slack two pounds of fresh lime in three
gallons of water. Allow the latter So
luton to cool and slowly pour it into
the former, adding 20 gallons OF water.
Strain the mixture thoroughly after it
has been well mixed and reject the
lime sediment.
Eau Celeste. For downy mildew or
brown rot of the Grape Dissolve two
pounds of copper sulphate in two or
three gallons Of hot water in an earth
ern or wooden vessel then add one
quart Of ammonia and mix thoroughly
with 80 or 80 gallons of water.
Kerosene Emulsion exterminate
Plant Lice and Scale Insects when the
use of arsenites is not eXpedient: Take
one-half pound OF common soap, or
whale oil soap, and add the same to one
gallon of water: heat this solution, add
ing it boiling hot to two gallons of
kerosene, and churn the mixture
thoroughly with Force Pump and fine
Pump and fine direct discharge nozzle
for five minutes. For general use, one
off hic ar,n1cinn no u1laI n
ten or twelve parts of water we'll mixed
together and applied with Spray
Pump.
Fish-Oil Emulsion against
Plant Lice and similar insects: Dis
solve the pound of Crystal Potash Lye
(Hirsh's) in three gallons OF soft water
heat to boiling point and then add
three pints of Fish Oil. Boil about two
hours and add water to make up for
loss by evaporation. This makes Fish
Oil, one pound of which should be dis
solved in eight gallon, of water. AS
an insectide, this solution less liable to
injure foliage than Kerosene Emuesion.
When well mixed, apply with Spray
Pump.
TO Make Bordeaux Mixture.-Fill
barrel tw0-thirds full of water, suspend
six pounds graduated sulphate of cop
per in coarse sack or cloth near the
surface of the water, where it will dis
solve in about twenty minutes. No hot

the est (ferrocyande of POTASSIUM
shows no change of color when added
to same. Test is made by dissolving
one-fourth pound Of yellow prussiate of
potash in two quarts of water.
Lime should be fresh and Stacked
some time before using and thoroughly
strained, a, all the time spent in pre-
pairing materials is repaid in using
them. Always add lime water to the
vitriol water.
The above recipe makes 80 gallons of
the Bordeaux Mixture.
TO Prepare Ammonical Solution Cop
per Carbonate. Mix six ounces of car
Donate copper with enough water to
make thick paste, to which add two
quarts of 26 degrees aqua ammonia.
For 80 gallons solution, convenient
method is to use one-half these quanti-
ties in each of two ordinary two-quart
fruit jars, as one will not hold suf1i-
cient ammonia to dissolve the copper.
For Spraying Vineyards Use Bor-
deaux Mixture until grapes are half
grown and then use Ammoncal Solu-
tion Copper Carbonate. Spray with
Bordeaux Mixture when vines are
about six inches long: again just before
blossOming: once as soon as blossoms
fall, and again in about two weeks, and
at intervals of two weeks with Ammon-
iacal Solution Copper Carbonate, as
long as rot appears. In regions where
rot has not been prevalent, the first
spraying may be omitted.
Pumps with Brass Working Parts
should be used when applying fungi
cides and insecticides that contain
acids. such as the Bordeaux Mixture
Eau Celeste, Ammoniacal Solution of
/ Copper Carbonate, etc, since the brass
resists the deleteriouS effect of the
acids When London Purple, Paris
Green and the Kerosene Emulsion are
used, Pumps with iron parts are not so
seriously injured, but Of course Pumps
with brass working parts are the hes t
and the cheapest in the long rum
since iron is subject to rust and corro-
sion. We are nov making all of our
Pumps with brass working parts.
