the grower for time, care and labol
spent in cultivation. But that the
doing Of anything SO necessary to ths
success Of the fruit grower should b
performed in way, and at a time
which should prove detrimental TO The
interests Of the fruit growers bes
jriends-thc beekeepers-would b.
much regretted, were it not for The
fact that such spraying, if properl,
done, will in no wise result in loss te
the apiarists.
Bulletin No. Z, as issued by The
United States Department of Agricul-
ture, gives full directions for making
and applying the variou, poisonous
compounds used 10 spraying for the
destruction of the harmful pests, and
states very decidedly that ono spraying
as described by the Department has
ever resulted in the slightest deleter-
ious effects upon the fruit subjected to
itp This will be welcome information
ITO all who feared that the spraying had
caused poisoning among those who had
partakcn OF fruit which had been spray
ed. 1t thus behooves all who employ
this means Of protecting their fruit, TO
follow carefully the modus operandi
as given by the Department Of Ag-
riculture.
On the subject of preparing the
arsenites (London purple. Paris green
and white arsenic) for spraying pur-
poses, the Bulletin says:
s'The poisons should be thoroughly
mixed with water at the rate Of from !
pound to 100 to $50 gallons of water,
and applied with force pnmp and
spry nozzle. In preparing the wash, il
will be best TO first mix the poison
with small quantity Of water, making
q thick batter, and then dilute The lat
ter and add to the reservoir or spray
tank, mixing the whole thoroughly.
.When freshly mixed, either London
purple or Paris green may be applied to
apple, plum, and other fruit trees, ex-
cept the peach, at the rate Of / pound
to $50 to 200 gallons, the latter amount
being recomended for the plum, which
is somewhat more susceptible to scald-
ing than the apple. White arsenic
doss little, il any, injury at the rate Of
pound to so gallons Of water when
freshly mixed.
.sAs shown by Mr.. Gillette. however
when allowed to remain for some time
1.-TWO weeks or more) in the water, the
white arsenic acts with wonderful en-
ergy, scalding when used at the rate O.
1 pound to 100 gallons from 10 to 81
per cent Of the foliage; the action o
the other arsenites remain practically
the same, with perhaps slight increase
in the case of London purple.
with the peach these poisons, wher
applied alone, even at the rate of
: pound to 800 or more gallons of water
are injurious in their action, causing
the loss Of much Of the foliage.
'sBy the addition Of little lime t,
mixture, London purple and Pari
green may be safely applied, at the rat
Of ! pound to 1876 to 100 gallons 0
water, to the peach or the tenderes
foliage, such as that Of the apple o
( most shade trees.
whenever, therefore, the application
Is made to tender foliage, or when tn,
treating with strong mixture is de-
sirable, lime water, milky, but No
heavy enough to close the nozzle
should be added at the rate of about
gallons to 100 gallons of the poison"

perhaps as much as any other (if no
more) affects the bees most seiiousl,
when not applied at the proper time
the Bulletin continues thus:
nWith the apple, in spraying for tn,
codling moth, at least two applications
should be made, The first, after the fall

brood of the codling.moth lays its egg
