done while the trees are dormant. For
killing the scales referred to we must
use a stronger solution than can be
safely used after the leaves are out.
Some summer spraying with weaker
solutions may be profitably done, but
where the work is properly and thor
oughly done before the leaves come
out there will be no need of the sum-
mer sprays.
East of the Cascade range the San
Jose scale is the pest that must now
be met No hopes need be entertained
of eradicating this pest; only ignorant
men or men who blow about what they
can do but never get it done, will talk
about getting entirely rid OF this in
sect. But we can so control this pest
so as to reduce its ravageS to very
low notch Many remedies have been
tried with varying success, but the
intelligent fruit men from ocean to
ocean have settled down on the lime
sulphur wash as the one remedy to
be depended upon in preference to
all others. Some still use salt as an
ingredient, but that is wholly unneces-
sary. We owe more to Professor Z.
V. Piper, formerly of Pullman Col
lege. but now of the department OF
agriculture. Washington, D. c., than
any one else for properly working out
the correct solution for COMBATING
the San Jose scale. He demonstrated
| that the salt was not at all necessary,
and by emitting it large expense was
saved
| Professor Piper recommended two
| formulate: One he called the lila so
luton and the other the 1-1-3 solution.
| The first named means one pound 0I
lime. one pound of sulphur and TOUR
gallons of water; in the other formula
three gallons of water are used. Both
solutions have proven effective with
us and with many others. we ordl-
narily use Is pounds of lime, 15 pounds
of sulphur and so gallons OF water.
This proportion need not be used IN
hoiliug the solution, but water should
be added to make this proportion be-
fore using. 1t is commonly SAID that
the solution must be applied hot, but
this is a mistake. 1t cannot be applied
hot: that is, it will not be hot When II
reaches the trees. Any spray Will cool
instantly if scattered as fine mist.
This much is true: The material
works better when hot, but 1t does not
deteriorate by cooling. 1t may STAND
over night or over Sunday and not
lose one particle of it's strength, but
if must be heated up again before
using or it will not work we'll III the
nump or through the nozzles. In TACT,
some of our best informed men claim
that the solution is more deadly to
the scale after it has been on the trees
for weeks and even months. This IN
creased deadliness is owing in part,
if is said. to the fact that the solution
being exposed to the atmosphere, I'M
dorgoes chemical change whereby
sulnhurated hydrogen is generated ana
that is a very deadly compound.
In order to properly prepare the
lime-sulphur wash person needs
good galvanized iron tank hololng
from one hundred to three hundred
gallons. We use two tanks, one hold-
ing $50 gallons and the other 40o gal
Ions. These tanks are set on Drlck
flies on a hillside SO that the liquid
will rim from one tank into the other.
Orr tanks are so arranged that the
material will run from the lower tank
into the tank on the spray wagon. we
never lift pound of water In our sum-
mer spraying and in the early spring
we pump from a we'll into the nrst
tank with a force pump.
Put the sulphur and water enough
TO make about one-third the quantity
needed into the boiling tank. start
the fire, and as soon as the water gets
boiling hot add the lime. The lime
must be good unslaked lime Inc
