Many ofcliardists spray the eo.iiins
moth and still grow very wOrny ap-
pi.s. The writer knows Of nn orchard

SPRAYED with an arsSnicai mixtures

n.Ieli,orhOoi WAS sprayed iwtc. ana

difference Why Is that on. man sprays
his orchard uni has very ii,ti. wotmy
fruit nni his neishbor. who also
sprays, has nearly all OF his apples
woriny? This IL question often
asked and frequently difficult To an

Or-hnr,iisi. differ widely In opinion
ms TO the number OF applications that
should he made. Some. noticing that
the worms are more abundant late In
the summer. think that spraying should
he continued throughout the season OF
growth and report excellent results
from spraying i've or SIX times. How
ever. II Is the opinion OF those who
have tested the matter mos; thoroughly
at the various experiment stations OF
the country that II does not pay TO
spray more than twice. II the two mp.
plicntions are properly made Mt the
best time.
Poison to Use.-IIcrc again opinions
differ. Probably Paris green is as
crcctunl as any. II well applied. and
II the liquid Is kept thoroughly agi-
tated during the spraying. Schccle's
green would probably he as cffectual
rs Paris green. Is cheaper. and remains
in suspension In water better. London
purple and arscnatc OF lime are read
lily kept In suspension In water but are
slower IN their action than the above
mentioned poison. and probably less
efrectual in their dcath.dcaling power.
They have the advantage of hcing
very cheap. Arscnate of lead Is kept
.E.I u. AL
Is remarkable for its adhesive quality
and its entire harmlcssness TO foliage
unless used in great excess.
Paris green. Scheele's green and
London purple ma! be used in the
proportion of one pound to 100 gallons
OF water. 1t Is best to mix the poison
in small amount of water first and
then in the full amount for which IL
was prepared. For each pound of poi
son. used. add to the water one or two
pounds of freshly slnkcd lime. This
will lessen the liability of the poison
to burn the foliage.
Arscnnte of lime by the KcdZic for
mula is prepared as follows: Boil two
pounds of white arsenic and eight
pounds of salsoda for fifteen minutes
in two gallons of water. Put into a jug
and label "poisoa." When ready to
spray. slakc two pounds of lime and
stir it in forty gallons of water, add
ing II pint of mixture from the jug.
If this formula is followed. be sure
and use n full measure of fresh lime.
otherwise some of the arsenic will be
left in solution in the water and will
kill foliage.
a somewhat simpler method of pre-
pairing arsenate of lime is to boil to-
gether for three-luarters of an hour
one pound of white arsenic. two
pounds fresh lime. one gallon water.
Use one quart of this to an ordinary
barrel of water tabout forty gallOns).
