THE CANKER WORM.


A series of experiments nave Just been
completed for the purpose of finding 4
remedy for destroying canker worms on
trees without destroying the fruit and
foliage Heretofore the use of arsenic,
which is an excellent remedy, destroyed
the fruit and foliage, and therefore the loss
of the crop for one year. In experiments
lust completed, trees seriously infested
b. the spring fall and yellow can
ker worms were completely cleansed
by using buhach six pounds; alco-
hol, one gallon; water, forty or fifty
gallons. Also by using, instead, whaie-oii
soap, ten ERunds; buhach, one pound :;
water, ten gallons. Either of the above,
thoroughly applied by spraying, viii Eff
fectually destroy canker worms without
doing any harm to the foliage, fruit o. tree.
oYsrER-sHELL BARK LOUISE
O. L. Crane, Santa Rosa. Sonoma county
Cal-You are correct; the specimens you
send are the oyster-shcll bark louise or
common apple scale When the eggs are
Matching. which is about this season in Sac
ramento and vicinity, spraying the trees
thoroughly with whale-oil soap ami sui
phur solution-onc pound to each gallon Of
Water-Will destroy the young scale, and
will not injurc the fruit or foliage. but
improve it. One pound of I've to each gallon
of water used will destroy it uhe,l die tree IS
dormant This is a very difficult species to
destroy, but excellent results have been
reached by washing with the lye solution
IN winter.
JUMPING TREE CRIC NE-.
Mr. Hall, of Folsom, writes
I send you specimens of Cynthiana g-aFa cut
t!Rgs, with lot of borers or borers eggs IN
them Please advise me what they are, and II
it would not be better to destroy the cuttings
chan to plant them
Reply: The cuttings you send are in
Tested by the eggs of the jumping tree
cricket (OrOchdris Sditdtorl. If you have
any cuttings infested as these are, I would
certainly advise you to destroy them, as
this is i Troublesome pest TO get into vine

GRAY BARK-EATtNG TEEvIL.
RT Northam, of AnaheiIn, Los Angeles
county, writes:
About four weeks ago set out some 30 fruit
and $50 orange trees, on the west side of one
yearold vineyard. About three days after plant
ing noticed what is supposed to be u tree wee
vii, and of which | inclOse specimens. They
eat the buds and leaves of both the decduous
and citrus trees they also attack the vines and
denude them of their buds. The orchard is on
ground that was not broken up until this year,
and it is a heavy soil If you know OF anything
that viii rid the trees of these pests. please no.
tify me.
Reply: The beetles you send belong to
the CWc7dinida and of the section known
by the popular name scut-snouted curcu-
lies / have given this species the common
name of the gray bark-eating weeyil tthc
technical name is ThricOiepiS siml(Ht0r}. 1t
appeared in several sections of the State
last year. If solution of ten pounds of
wtale-oil soap and three pounds of sulphur
boiled together in ten gallons of water, and
sprayed on the trees and foliage, does not
prevent its ravages, a solution OF the
following propOrtion-one gallon OF
alcohol, and six pounds of buhach,
mixed in twenty-five gallons of water-will
ctfectually destroy the beetles that it
touches; or, in ten gallons of whalc-oil
soap and sulphur solution add one pound of
buhach Apply when the beetles are feed
ing. In solutions where buhach j. Used
apply Immediately after using.
HOW LONG, 0, HOW LONG
VIII persisting ignorance prevail? We
make the above query, in relation 10 the
transportation from one place to another,
OF empty packages that are used for ship
ping fruits last year. \ short time ago, in
making a hurried examination of some or
chards near San Francisco bay, it was no
ticed that large shipping boxes apparently
over 2.000) had been received from San
Francisco and piled up in the vicinity of
the orchard. Appearances indicated that
they had been in use last year, which led
to an examination. One box was broken
asunder, yielding at least thirty larvp
Of the Goblin moth, which had entered the
uuch-used package 10 hibernate. Inquiries
ELECTED the following information:
4 firm in San Francisco which deals eX-
tcnslyely in fruits, are the pOSSeSsors of
many thousand boxes which they use as
return packages, in carrying their pUr-
chases Of orchard produce apples and
pears TO market. When preparations are
being made for the following spring trade,
these infested boxes are shipped to orchards
from which they expect fruit the coming
season Can it be said in favor of the
shippers that they are ignorant Of the
such iruit-growerS2 We wish that a
negative could be given The subject has
been written of extensively; and litigation
on the subject brought it prominently into
notice, especially the case of the People vs.
A. Lusk 4 Co Among the commission
dealers Of San Francisco especially those
who contributed funds To oppose the quar-
antine rules. it may be taken for granted
that the subject is generally understood.
L. reference to the shipment of boxes re-
frrrcd to say 2.0O0-a low estimation
would be ten larvae in each box. aS com
pared with the one box eXamincd-the
orcha-diSt received therefore say 10000
moths, to propagate their kind on his
premises Fruit-growers should protect their
orchards from such invasions by forbidding
return boxes of any kind being brought
upon their premises or in the vicinity of
their orchard property, except when thor
cughly disiniected by dipping and remain
ing in boiling water at least three minutes
or by iissolving one pound of potash, or
concentrated I've, in every twenty gallons
Of boiling water. Two minutes immersion
will be sufficient. If this Is not done, ut
least insist that the owners of such boxes
retain them in their city Storchouses or
cellars until the pests have passed their
transformations and escaped from their
winter habitation.
