How to Spray.
The driving spray, as now used, is
applied only TO the blossoms, no at
tention being paid to the leaves, but
every calyx cup must be filled with
Inc poison. To do this, the nozzle
should be set SO as to throw fine drops
a distance of six feet before they
break into q mist. With one hun
dred to two hundred pounds of pres
sure this can be done. Nearly all of
the blorsoms point upward. few on
the Outside of the tree point out, and
beneath the branches some point
down always however toward the
light. The nozzle should then be
passed up and down the limb, hold
ing 1t within eighteen inches of the
blossoms and turning It so that you
nre sure to drive the spray straight
into the top of each one of the calyx
cups. continuing until the last one
is filled. In practice this is accom-
plished on large trees by stopping
the outfit Just before one reaches the
tree and spraying all that can be
reached from that position, turning
the pole in the hands and reaching
underneath tho tree and spraying
up, working up and down on the
side, spraying in. and from above

up and down the large branches in
side the head. Then driving on by
the tree and repeating the same pro-
cess from the other quarter. BY
driving up one row and down the
next. in this way each tree receives
four sprayings. each one Of which
will cover nearly one-half Of the
tree. Small trees may be sprayed
with one stop on each side.
The Amount to Apply.
It has been found that In practice
this kind OF spraying requires about
two-thirds as many gallons of spray
as there are to be bushels of fruit.
The question is often asked. How
much can you spray in day with a
given outfit?" a question that can
not be answered In terms of acres.
because II depends entirely upon the
size of the trees and the amount OF
blossoms. A barrel pump with one
bordeaux nozzle will throw from three
hundred to four hundred gallons OF
spray per day. A double-acting pump
with two lines Of hose and two noz-
zles will double this amount, while
the gasoline power outfit with four
mi
twice as much from each nozzle as
in the case of the hand pump or the
double-acting one. on account of the
increased pressure, but better work
will be done from the power sprayer
II only two nozzles are used, and
with the double-acting pump IL only
one. BY figuring the amount OF APP
pies expected per acre. IL will be easy
TO ascertain how much each style of
pump will do in day. In the writ
er's experience there has been no
difference in the efiiciency between
the hand pump and the power spray.
II Is entirely question of thorough
ness of application in each case.
The Equipment Necessary.
Half OF the failures in spraying
that the writer has observed have
been through lack of the proper e.
quipment. II Is impossible 10 get

even at the present time. The first
essential Is a good pump. Only the
very largest of the barrel pumps are
strong enough for this work. Any
OF the double acting pumps will fur
nish pressure enough. and for large
orchards the power sprayers have
proven their worth. For any OF
these pumps one-half inch hose is as
large as is desirable, and this should
be from five to seven-ply, 10 with
stand the heavy pressure necessary.
Twenty-Five OF such hose, with an
eight or ten-foot bamboo pole. equip
ped with cutoff, furnishes sufficient
length to enable one TO do good work.
On the end of the pole should be pla-
ced a bend or angle OF about forty
five degrees. carrying nat-spray noz-

outfit small trees can be sprayed from
the wagon. or even from the ground,
but for the larger trees the tower or
has ever used O well-made tower or

guilty of going back to the old meth
cd. The Bean Company have made
a neat bend especially for this cod
ling moth spraying, and 1t might be
well in this connection TO warn peo-
pie against the smaller types OF fiat
spray nozzles sold under the name or
bordeaux that have only one spray
Ing surface, as they are too small for
this work. The large-sized bordeaux
with two surfaces. has the name
stamped on the humble, while the
others do not.
When to Spray.
As soon as the blossoms fall the
five green calyx lobes begin 10 turn
up. and In ten or fifteen days have
completely closed over the caiyx cup.
All poison that is to be placed In
these cups must be driven In there
