from the Aspidiotus p1niciostls. 1t has but
one brood year
The Aspidiotus conchi,,formis, or oyster
shell apple-bark louise, like the last-men-
toned has but one brood year. 1t is
found on the apple chiefly, but sometimes
is found upon the pear. 1t is confined
chiefly to the coast counties, but is also
found in other places in the San Joaquin
valley. Owing to the thickness of the
armor, it is one of the most difficult of the
scale to exterminate.
ANOTHER REMEDY.
half pound of I've and half-pound of
commercial potash to one gallon of water.
The gAspidiottls antantii is confined to
citrus trees. The trees affected by this pest
become very sickly and non-productive.
1t is disease of leng-standing, but has
until lately been little fought. Various
soap remedies have proven quite efficient.
The red orange scale somewhat resem-
bles the aforementioned and is found in
orange orchards in Los Angeles county.
One of the many remedies employed in
fighting the pest is the following: Eight
pounds caustic soda and II gallons of whale
oil to 100 gallons of water. This exceed
ingly cheap wash seemed to accomplish
good results. Others were using pounds
of potash to 100 gallons of water, seemingly
with good effect.
,Secani,tm olea-the olive seale-is one of
the most common on the coast. Spray the
trees in winter with weak-lye washes, say
one-quarter pound concentrated I've, one
pound potash to one gallon water.
The essay embraced the black scale Le-
canium hesperidum) or soft orange scale,
Lecnliitm henisphericttm), the grape scale,
cottony cushion scale, etc. He also gave
formulas for different solutions that had
been used successfully.
The ravages of the pest, according to the
" chief bug inspector" are confined to the
southern portion of the State, the orange
groves of the middle section of the State
and the foothills bordering on the Sacra-
mento valley having not as yet been af-
fected by them.
WHAT OTHERS THINK ABOUT 1T.
At the close of the reading of the essay
by the Inspector of Fruit Pests, he was
asked many questions regarding the differ
ent scale and the methods used for their
determination.
Mr.. Lelong spoke at length on the cot
tony cushion scale, a subject at which he
was perfectly at home upon. He had made
the insect, its ravages and the best methods
of its destruction study, and gave the Con-
vention many points from his observation
and experience In Los Angeles county
the Board of Supervisors, under a State
law, passed an ordinance creating Pest In
spectors. The Inspectors met with much
opposition. The owners would not cut
down their trees unless they were paid the
value of a three years crop. The Inspect
ors went to work under the ordinance and
served notice on all owners of infected trees
to clean them within fifteen days. 1t costs
money to enforce laws, where a compliance
indicates an apparent destruction of prop
erty and loss of value. The law, however,
was enforced, but it cost Los Angeles from
5000 to $4,000 to do it. The law as it
now exists is not dead letter, is not I'M
constitutional as claimed by some, still a
law could be framed that would be simpler
and more effective. He said there were
many methods of spraying and cleaning
trees infected with scale. Most all of them
were good, but none of them could be
called exterminators, with one application
Some tent their trees and then fill it with
some kind of gas. This of course reaches
every scale, no matter where he may be To-
Gated. This gas bath lasts for fifteen min
utes, but in many cases the trees after
wards show the evil effects of the gas He
said it was something new and he was in
the dark as to what Kind of gas was used.
Spraying from the ground, he said did not
saturate the foliage sufficiently to destroy
all the scale. The most effective way was
to use a step-ladder, and spray downward.
IT CAME FROM AUSTRALIA.
W. g. Klee said the true home of this
insect seemed, from all that could be
learned, to be Australia, and he advised
every farmer who had any friends in that
country to write and ascertain if they had
any remedy to offer.
Mr.. Block, of Santa Clara, said this scale
did not confine its ravages to citrus fruits,
but was also found on locust and acacia
trees.
Mr.. Lelong said this was true. They
affect every kind of tree and plant They
do not thrive in the olive. Olive trees in
the center of infected orange groves are
found to be entirely free from scale. This
scale is very destructive in Cape Town,
Africa.
Mathew Cooke said the Goblin moth was
very bad in Santa Clara valley, as was also
the San Jose scale. Both of these pests
could be got rid of successfully if the fruit
growers will only follow instructions. They
must learn the natural history of the in
sect, and this done, there is no insect he
cannot successfully fight. 1t is going to
cost something; but the fruit-raiser will
make $15 for every s. he puts out in that
way The white scale is spreading in this
city. 1t is fact that some orchardists who
have filthy trees will not allow them to be
cleaned unless they are paid for granting
the privilege. The amount that is lost
annually in this State by these insect pests
represents an amount greater than that
which costs to run our State and county
Governments.
ON THE SACRAMENTO.
Sol Runyon, of CORTLAND, one of tie
most extensive orchardists on the Sacra-
mento river, gave his personal experience
in fighting the scale and Goblin moth. He
had tried almost every remedy that had
been recommended, and had been more or
less successful with all. The best in his
opinion was the caustic soda and potash
wash. The trees he washed last season
