The Hood River glacier. (Hood River, Or.) 1889-1933, 1906-01-04

made in three different localities in
the state of Ohio by professors Of tie
experiment station upon the CON-
parative merits of the two sprays; the
results we're pronounced decidedly In
favor of the lead that is, much
larger percentage of clean fruit was
secured from the same number OF
specimens experimental with, from
the latter material. Some may ask,
has it other special advantagesS Yes
it is much more easily prepared, as
there is no Stacking of lime nor boil
ing of poison; there is no clogging
of nozzles, as the preparation con-
tains no gritty sediments another
and more important consideration, Is
the ease with which the apples are
wiped, the cost not being one-hah as
much as when the other spray Is used.
Two things, however, which we're
claimed for it, did not prove true
with me, viz: That it would not
precipitate, and that it gave sufh
cient color to the foliage to determine
what pant had been sprayed. 1t
needs to be stirred the same as other
sprays, otherwise it settles and pre-
vents uniform distribution. The
color impaired to the foliage is
scarcely perceptible, but this fault
may be easily overcome by the addi-
tion of little lime to the mixture.
So much for the material to be used;
now few words as to the pump and
power for applying this spray. A
greater part of the spraying In this
state has been done by hand power
from so and 100 gallon barrels, using
one or two leads of hose; with two
hose in use, two men are required to
produce sufficient power. In Hood
River valley two different gasoline en-
gines have been used for producing
power, but with not very satisfactory
results A few of the Niagara Gas
Sprayers are in use, it is claimed,
with fairly good results with this
sprayer no pump is uses, hence no
pumping Is required; the gas being
conveyed from strong metallic cad
T die into an airtight metallic tank con-
tanning the spray the expansive force
of the gas being thus used to produce
p the necessary power. One objection
! brought against this sprayer is, the
, time and expense incurred in sending
/ the caddies to San Francisco to be re-
filed with gas.
a Two Compressed Air Sprayers have
also been used; this machine, CON
sisting of pump and spray tank, is
mounted on wagon; the pump being
geared by sprocket to wheel OF the
wagon; the motion of the wheel in
driving puts the air compressor pump
, in motion thus giving the power for
forcing the spray. This has not been
= entirely satisfactory, as when trees are
large and close together, the distance
IS not great enough to get up power
: sufficient to run two leads Of hose
constantly.
An improved Wallace Compressed
) Air Sprayer has recently been brought
to Hood River. 1t is known as the
, "Duplex !" that Is, two pumps, each
being attached to wheel on either
side by sprocket; it is claimed that
this will produce ample power for
throwing constant stream through
; two or even through leads Of hose
! II it will do what Is claimed for 1t, a
great advance has been made, as the
work of pumping ty hand Is both
laborious and expensive. For com

= large enough Use light, but strong
. extension rods; for tall trees, a ten

How often shall the spraying be

y might be answered by saying: at least
. often enough to keep the fruit so

:, With the arsenate Of lime spray IT
= was formerlyIthought that every three
Il weeks during the summer, up to with
in two weeks of picking time, was
3 often enough; others preferred to
rs spray every two weeks, and some as
g often as every ten days, 1t is claimed
q that the arsenate of lead spray is not
d so easily washed off or diluted by rain
is as are other sprays; and hence, that
there is not need of its being applied
r so often, am, however, considerably
l. in doubt upon this latter point. The
le frequent rubbing of the leaves over
s. the fruit, caused by the action OF the
% wind, rubs off the spray, thus leaving
1t the fruit exposed to the attack OF
ID pests. A rainfall of any considerable
j, amount, as soon as dried off, should
to be followed by spraying in order to
10 warrant safety.
at Long ago some phylanthroplst,
re prompted by desire to inspire the
ly young with taste for the planting
or and culture of trees, wrote this terse
IN line. "He who plants tree, has
lis made a friend" But friend once
le made must be cherished, and bis
u friendship still cultivated, or it de.
Q, clines in ardor; he who would retain
is a friend, must be quick to respond
On reciprocal to every proifered courtesy
