WAR on THE HOP LOUISE.
A Cheap Method Of Spraying-Vermin
on the Plum Trees.

Kent Journal. Jan. Is
p. c. Hayes, president Of the Hop Growers' As
ISOLATION. was in town on Tuesday. He has
some new idea. regarding warfare with the hop
lice. He considers the usua. method OF spray
ing wasteful of material. and proposes to save
1t as much as possible. He will have made
sort OF broad dripping-pan arrangement OF TIN
to close around the pole at the ground to catch
the emulsion as IL drips from the vines boy
viii attend TO the placing of the receptacle, and
empty it into barrel other vessel for the pur-
pose. In this way there viii be little waste, and
the same material may be used over and over
again. He thinks that great deal more than
the wages of the boy viii be saved. Another
thing that suggests itself to this man Of ideas
is that it il waste of time and material to spray
an entire yard when il is weil-Known fact that
in the start it is only now and then hill Is at
tackled. He will go over bis yard. carefully no.
ticing the hills where the insects begin work
ing, and place q peg in the ground at each.
The observer will be followed by the sprayers,
who will concentrate their work upon the vines
indicated. Mr.. Hayes will begin spraying early
this year. He believes It bad policy to wait
nntu the entire yar7d1 yard affected Jus,
millions of the enemy. When this is
done there will always be too many that VIII
escape the most thorough spraying: Those left
propagate so rapidly that as the foliage grows
dense, it becomes more and more difficult TO dis
lodge them.
President Hayes suggests the calling OF q
meeting of the Hop Growers Association some
time next month. He will make the PROPOSE
ton at that meeting for the hop growers to es-
tablish a small plant for the manufacture of
whale oil soap. He says the price OF this article
is advancing, and If the growers take hold OF
this matter Alright they can save considerable
money, while at the same time they will be sure
OF getting uniformly good article.
Mr.. Harm. who was present at this interview,
though spraying thoroughly last year and yet
losing heavily by the louise, has lost no faith in
the efficacy of the sprayer. He will begin early
also. He will discard the use OF kerosene alto
gether, having found that whale oil soap and
water are exactly as good and far less expensive.
Mr.. Harm has the best of evidence that cold
water alone is worthless. It will knock off the
lice, but will not kill them, and the next morn
ing they are found at work again in
fun force. Very cold water IL also in
furious to the vines. Lime about the
hills he considers useless ALSO knowing OF two
yards side by side, one of which was treated to
lime thoroughly, while the other was not, and
the latter gave much the best yield and was lit
tie ubled By lice
The gentlemen united in the opinion that all
prune and plum trees in the valley should be
sprayed before the winged lice begin their fight
to the hop yards. Mr.. Hayes said the hop grow
ers could better afford to do this work for their
fruit-growing neighbors than to have the work
neglected
None of them reported seeing the hop louise
anywhere yet this winter.
