1t is the tendency OF this disease to
work up the trunk to the crown, when
the tree is girdled and dies. In oon-
nection with this disease black shoe
string like strands may be found on
the surface of the roots. Tie cause Of
the disease is a mushroom like fun
gus growing on dead wood, most
common on dead OAK stumps. 1t at

more often on newly grabbed land.
There is no remedy for this and when
It Ia discovered the tree should be cut
out and all the big roots removed, ss

Prof. jackson took up a discussion
of crown gall aud hairy root. He
said that the hairy root was distriE.
uted through nursery stock and was
caused by bacteria attacking at the
point of the root graft. 1t is con-
tag Gus disease and such trees never
make good loot growth and seldom
come into bearing, According to Prof.
jackson, the "fruit pitt" sometimes
OF an unknown cause. 1t seems, how.
ever, to be the result of lack of bal
ance between the amount of water ah
sorbed by the roots and that given of
by the tree.
Prof. Winslow, the Canadian eX
pert, was introduced and stated brlet-
ly that he WAS here more to listen and
learn than to speak, since the orchard Q
in his part OF the country we're yet In
their infancy. lie said the conditions
In British Columbia we're different
from ours aud that at present their
interest was primo pally in planting
and bringing up trees, as they we're
not yet bothered with many of the
pests. lie said that he had visited the
Wenatohee and Yakima districts which
we're about tour years ahead of his
own country and he WIS impressed
that Hood River WAS two years ahet
| Of the Washington sections. lie said
that Hood River seemed to be sue
| ceeding In her object which was aps
parently TO grow "still more apples,
from still more trees, to sell for still
more mouey and gain still more repu-
tation."
Just before the noon hour, DR..
Stanton Allen, who has just returned
from the east, spoke OF the orchard
conditions rs he tound them there
end he was followed by Joseph Porter
and j. Il, Garter, who made some
brief remarks. Shortly after moor,
A. |. Mason, who was chairman of the
meeting announced that dinner was
ready down stairs and the crowd re
paired to the lower floor to partake oil
a bountifnl spread which had been
prepared by the ladies Of the Pine
Grove grange. After the speakers had
sufficiently recovered from the excel
lent dinner and an hour or 30 OF in
formal visiting among the growers the
afternoon session was called with 6
much larger crowd than had been atlt
to get out to the morning session.
| This second session WAS opened by
Prof. Griffith, who gave an account
OF the work he had done last year In
man q Friday. The Allen orchard
had suffered with apple soab and he
conducted spraying tests with the
lime sulphur solution with the result
of very little scab while other or
chards In the vicinity which we're not
sprayed we're affected. he said that
If the fungus could be kept off the
leaves the fruit would be tree OF soab.
he Newtown Trees usually suffer
most from the scRb. The lime sui.
phur was used IN the Alien orchard
while Ia the trees of Sherman & Fri.
day comparative experiments we're
made with lime sulphur and Bordeaux
mixture.
As the apple crop was rather small
it was necessary to figure out the re.
suits by counting the scabby leaves
and thus learning the ell sctiveness OF
| the treatment. In the Sherman y
| Friday orchard the trees averaged the
flowing number of scabby leaves
unsprayed 542, Bordeaux, 473 and
lime ulphnr, 1903. In the Allen or
ohard the number of scabEy leaves OF
the unspIayed trees was l33, while
where the lime sulphur was used nc
affected leaves could be found. In
the first tests cone shaped mist noz'
zle vas used, while the foliage could
DO drenched with the Bordeaux nCZZlt
which was used in the Allen orchard
10 Inefi ectIve slrayiDg IN the hrsl
case is attributed the wide difference
in the results where the lime sulphur
was used. When the count WAS made
IN the fall to ascertain the results FOL
the season, the comparative expert
ment showed unsplayed 266, Bor

unsprayed trees ia the Allen orcharC
showed II scabby leaves and ta'
sprayed trees showed III leaves affect

these results showed the desirHbil
ity uf the lime sulphur spray for apple
scab, which was almost wholly driver
out OF the Alien orchard. ln th'
Sherman & Friday orchard where th'
bordeaux mixture WAS used 59 pc
cent OF the apples were burned by TN
spray. 1t IL thus shown that lime
