Jersey. In form Cnl8 resembles tne Wig
oroux sprayer, or tho "l'Eclaire' of Yer
morel, OF French manufacture, but the
pump is constructed on different princi-
pies. With the better appliances of this
class one man Can easily spray from
three to five acres of vines per day.
The spraying should be done thor
oughly; that is, all the parts ought to be
covered with the application, but care
should be used not to drench the plants
or vines. An excessive application is
not only wasteful, but liable to result in
injury to the objects treated.
| The amount OF material used per acre
will depend upon the season, extent of
foliage growth, and the apparatus en-
ployed in applying it. In general, we
would recommend for the liquids. rs gal.
Ions for the first, So for the second, and
As for the third application.
The nozzle used should give fine
mist like spray. or rather cloud OF
vapor, which will envelop the plants,
wetting them completely, but not so
abundantly as to cause the liquid to drip
from the leaves and shoots. Both the
Eddy chamber or Cyclone nozzle, and
Nixon's climax nozzle will yield spray
of the desired character. The latter is
such compounds as the Bordeaux mix
ture are used, nozzle with degorger
or device for clearing, like the Vermorel
nozzle, is necessary.
As with liquids, so with powders. they
should be distributed finely and evenly,
their presence on the leaves, etc., after
application being just psrceptible. An
excess of such powders as sulpha-

properly applied) is very likely to iniure
the plants, particularly under hot sun
shine. Bellows furnished with outside
receptacles for the powders are necessary
as the corrosive action of the powder
will soon destroy the leather If placed in
contact.
As to the amount of powder to be used
per acre, we would say for the first treat.
ment, So pounds, As or so for the Sec
ond, and 60 pounds for the third.
In respect to the remedies enumerated
in the above circular, the use of
the simple solution has in many
instances resulted in injury to the
foliage. As it is not advisable to reduce
the percentage.sof sulphate of copper in
the solution by the addition of more
water, the simple solutions had better
be discarded in treatment during the
growing season.
Eau celeste also has. in the hands of
some, injured the foliage materially, and
modification of the original formula is
suggested in order to overcome the dan
ger. In gallons of hot water dissolve
2 pounds of ordinary car Donate of soda !;
mix the two solutions, and when all re-
action has ceased add IL pints of liquid
ammonia when desired for use, dilute
to % gallons.
1t is stated that all danger of injury to
the foliage from the first applications,
made while the shoots are yet young and
tender, may be entirely overcome by
preparing the eau celeste for the first
treatment in the following manner: Dis
solve one pound of sulphate of copper in
a gallon of hot water; to this solution
add liquid ammonia, little at time,
until all the copper is precipitated the
liquid is then turbid, and blue in color.
Add two or three gallons of water and let
it stand to settle; then pour off the clear
liquid, which contains sulphate of am
monia-the compound which causes the
burning of the leaves. Then pour upon
the precipitate left in the vessel Just
enough liquid ammonia to dissolve it..
The result is clear liquid of beautiful
deep blue color. When required for use,
dilute to twenty-five gallons.
Eau celeste, prepared in the ordinary
manner, may be used without fear after
the vines are in full foliage.
considerable latitude is allowed in the
Quantity of lime and copper sulphate in
the Bordeaux mixture, but the amount
of the latter ought net to fall below four
lper cent. The most recently recommen-
ded formula for the preparation of this
compound is four pounds of sulphate of
"copper", two pounds OF lime, twenty five
gallons of water. This reduces very
much the cost of material, and the labor
in applying is far less than when pre-
pared according to the original formula,
but some have found it to be inefficient" !"
Although the above extracts have
Especial reference to the treatment of
vines affected with mildew and black
rot, yet, in view of the fact that in all
probability the present trouble with the
vines is the work of a fungus, which at
this time of the year is to be found in
the bark of the spurs of the vines, and
possibly also in the leaves, and frag-
ments of canes lying about on the
ground, it is plain that preventive meas
ures are the most suitable. Here it may
be well to remember that, a correspon-
dence as to the effect of sulphuring
vines: "Report Is, January z, 1885,"
tends to show that free use of sulphur
has decidedly beneficial effect as pre-
ventive, especially if proper precautions
be taken as to the kind and quality OF
sulphur used, time and manner of appli.
cation, and atmospheric conditions pre-
vailing at the time of application.
