be perfectly useless. He stated that
two or three years ago the expert
ment station had conducted work
with sulphur and lime wash, obtain
| ing satisfactory results and much
valuable information. Some sulphur
| lime compositions were found better
/ than others for killing San Jose
scale and certain soft-bodied insects.
! In mixing sulphur-lime wash two
Substances must always be consider
ed-espeeially in boiling it; two sub
stances, sulphide Of lime and hypo-
i sulphide, are formed. Whenever
you boil lime and sulphur with water
/ you set those TWO things" said the
speaker, and the sulphide form l.;
the thing that does the killing. The
| longer you boil the mixture, the less
efficient it is-after you have boiled
! it long enough. Neither lime or
sulphur will dissolve in water, and
the combination only takes place
when the two are boiled together
Just as soon as your lime is slack,
| put the sulphur along with it and
boil It. 1t will dissolve plenty in
an hour After that, you make Ii
worse
DON'T PUT ANY SALT IN 1T.
And don't use as much lime as
you're doing here
There is no benefit obtained by
withdrawing your trees. 1t won't
even kill the soft bodied insects.
I'VE recommend one pound of
lime 10 one pound Of sulphur This
just makes the mixture white enough
so that you can see where you hit the
tree. Or, one pound of lime to two
pounds Of sulphur will make a good
insecticide, though you can't see the
whitewash so we'll
USE GOOD LIME
And usually you can buy bet
ter spray mixture than you can make
and it's cheaper and less trouble.
There are several good brands On the
market, but | don't pose as advertis-
ing any particular one of them. But
unless you have an exceptionally
large orchard, it will be cheaper for
you to buy ready-made mixture
than to monkey with it yourself.
Nine out of ten of the really big or
chards don't make as a good a pro-
duet when they mix 1t themselves as
can be bought in the open market.
You can use the Eagle brand OF
dom, because there is no free acid in
it and age don't hurt it. Either ar
senate of lead or Paris green is as
good three years from now as today,
for it keeps well. You can safely
use arsenate of lead in dust spray,
though it's hard to get the pasty lead
to mix we'll. 1t is almost impo--
sible to get it uniformly distributed
the dust.
DON'T HEAT YOUR SPRAY.
Nothing is gained by it, for by
the time it is three feet from the
nozzle OF your hose it is as cold as
the air about it. And hot spray rots
and rusts your pumping apparatus"
An Instructive Exhibition.
In the afternoon the scientists
from the State college, Prof. Littooy,
president Of the county horticultural
association, and a large assemblage
of interested fruit growers, adjourn
ed to the orchard of B. B. Holcomb
west Of town, where several spraying
were given, and various
types of spraying machines publicly
tested. Among those machines ex-
perimented with and with which
demonstrations were made for the
edification OF local fruit men were
the dust spray, the geared spray at

are working today at Holcomb's or
chard and also at the z. A Lanham
orchard. assisted by Mr.. Littooy
Prof. Melander will take charge Of
these orchards and carry the work
the whole season.
At the close of Yesterdays demon
STATIONS several growers came up
and thanked Professor Melander for
the information impaired and said
they expected to spray their orchards
again. right away, though many of
them had already been sprayed once
this year. They felt that after
watching yesterdays exhibitions
that they had not done the work
right, and had learned something of
the right way of doing it by watch
