DUST SPRAYING.
Interesting Article on How to Prepare
Powder for Use.

In the September number of the
Fruit Grower in Questions and An
sweTs, j. G. b., Saluda, N. c., asks
for information about the dust pro-
cess of spraying fruit trees. Perhaps
| can give some points from actual
experience that might interest and
benefit him as well as other readers of
your most valuable journal.
My rig consists Of No. 6 Ideal du-
plex corn grinder manufactured by
the Stove Mgr. Co. of Freeport, Ill.
This machine costs about Sl8 | Also
have a shaking shoe corn meal sitter
with No. 30 brass wire. This sieve
can be gotten of any one who makes
milling machinery for about $40; this
sieve b speed of about 600 revolu-
toins per minute. This outfit can be
driven by six-horse power either
steam, gasoline or horsepower; most
fruit growers and farmers have an en-
gine of some kind, and if not any
thresh ng engine can be hired for
small compensation. This little,
cheap outfit has a capacity Of from
one-half to one ton Of dust per
das. A ton of dust will probably cost
about S25 for actual material and will
spray thoroughly three app ications
go acres of 20-year- OLD apple trees.
The above outfit will do the work for
whole neighborhood. The following
directions will be found useful and
satisfactory.
Make three boxes six feet long, 15
inches deep and 80 inches wide, of
wood that will not catch fire readily,
and put three bushels of unslacked
lime in each box; now dissolve %
pounds of bluestone in ii gallons of
boiling water, pour the above guam
tity of liquid bluestone on each three
bushels Of lime, which will reduce it
to a hot, dry dust. eve have demon
strated that the virtue of bluestone is
not reduced by the Stacking process).
And no matter how finely bluestone is
ground, If used ON tender peach leaf
it will burn it full of very tiny holes.
We use three or four boxes in order
to prepare that many barrels of lime
at time. Let this hot lime stand
over night to cool, and see there is
no fire in the boxes before retiring.
Next morning ad1 25 pounds of
-four of sulphur and five pounds of
Paris green to each barrel of lime and
mix thoroughly; run this over the
sieve, which will tuke out about half,
and the rest which goes over the sieve
must he run through the grinder, u.s.
ing the extra fine burrs. As most of
the sulphur and Paris green will go
through the sieve in the first opera
tion, it will be necessary to mix the
part from the sieve and that from the
grinder together. There would be no
need of sieving except that the lime
with the fine part in it packs in the
mill and does not feed, but when the
fine part is sieved out the rest grinds
nicely, and fine enough SO as to not
need sieying again. Do not use by
drafted lime, as you ever know its age
nor strength; it is also too fine; it
balls in the machine and is so fluffy
and light that when it starts upward
you never know where it viii light.
The formula which | have given is for
apple trees and has proven so much
superior to the liquid, both as flung.
icide and insecticide, that we have
relegated the liquid process.
This formula will also exterminate
the green cabbage worm and clear out
slugs from currants and gooseberries.
For grape rot aud peach rot use II
pounds of bl1estone and sulphur each,
to the barr Ell of lime; leave out the
Paris green; it is very effective and
perfectly harmless both to fruit and
foliage. Last, but not least, is the
machine with which to do the spray
ing. We own the Cyclone, and two
other makes of sprayers, and in actual
orchard tests the Cyclone did 80 much
better than the other two that we could
not afford to use them If they cost us
nothing. ID. Il. Miller, In Western
