The Hawaiian gazette., 1897-10-22

Letters are received from Hawaii. |
Maui and Kauai. stating that they have |
the aderatus umbrosus or japanese /
beetle and say: we want assistance |
Of some kind. Send us its enemy. Send I
US some Of Koebele's beetles. Send us
toads- Come yourself. Something
must be done at once"
Professor Koebele has sent the de- |
partment beneficial tat least il is so
hoped insects from Mexico and the
United States, and instructions where /
&c hberate them. As soon as thev
here. he advises that they be
distributed on all the Islands.
This is what Professor Koebele saws
in regard 10 the incubation of the
Aderatus umbrosus Japanese beetle):
Search under the bushes upon which
the insects feed and you will find some
dead beetles; use magnifying glass.
and those beetles that show white
line on each of the abdominal plates
are the infected beetles; carefully save
these and take TO the office. Procure a
quantity of the live beetles and
camel-hair brush; take the brush and
rub the point over the abdominal
plates of the infected beetles: now
take the live beetles one by one and
opening the wing covers. pass the
point OF the brush under the wing COW
ers onto the back of the beetle: place
each live beetle after incubation into
large glass jar. You can put from one
10 two hundred of the beetles into
one jar; place in the jar some yegeta-
that he ha.a+1a-
very important that the beetles do not
die of starvation. In five or six DAYS
the beetles will begin to die from the
effects of the incubation. and in a few
days more the fungus growth will be
plainly seen. During the period of in
oculation the contents of the Jar should
be kept slightly damp. When about
pint of the infected beetles have been
obtained they can be put into a box
about is inches square and 6 or S
inches deep. An inch of damp soil
should be placed over the bottom and
the infected beetles strewn over the
soil. Place food in the box and as
many live beetles as can be procured.
Every three days one-half can be taken
out and like quantity put in the box.
The beetles taken out can be strewn
on loose soil underneath such plants
as the beetle feeds on, or can be used
10 start other boxes.
PROPOSED NEW INDUSTRY.
Cobra yields perhaps a greater per-
centage of oil than any other of the
great oil-producing staples, giving as
high as 81 per cent of pure oil Samoa
exports 5000 tons annually, which
would mean about 300 tons of cocoa
nut oil.
This nut is destined to become one of
the most valuable products TO civilized
man, as it always has been to the ma
tiyes Of countries where it is indig-
enous.
The recent perfection of methods for
reducing its fatty oils into a cheap and
healthy substitute for animal fats for
use in the household economy will
cause a great demand for the nut. A
firm in St Louis is manufacturing CO.
coanut butter on a large scale
We have large areas of waste and
wet land that could easily be made
productive if planted with cocoanut
trees. What a beautiful park those
miserable, unseemly swamps-an eye
sore to the intelligent visitor and a
nuisance to the situated
on the makai side of the Waikiki road
and mauka of number of beautiful
residences along the beach. would
make with the expenditure of a little
time and money. II is almost certain
that everyone with residences in the
vicinity of the swamps mentioned
would contribute literally toward hav.
ing them filed up.
Free advice does not amount to
much, but it is suggested that if this
large estate would donate the useles:
property mentioned TO the public, the
Government and its people would con-
tribute literally towards having il
made one of the most beautiful parks
within the environments of Honolulu
and it would be as much of a monu-
ment as the chapel at Kamehameha
and Pauahi Hall at Punahou.
ANSWERS TO CORRESPONDENTS
The experience of the writer is that
potash salts are very effective as in
secticides, destroying cut-worms, mag
gots, plant-lice, while not injuring the
plant.
Potash salts may be purchased al
about 81 per hundred pounds.
MAUI.
The following formula and direc-
lions, if properly carried out, will pro-
duce an effective solution: Unslaked
lime, 40 pounds; sulphur, 20 pounds
stock salt, Is pounds; water to make
60 gallons.
Directions-Place 10 pounds of lime
and 20 pounds of sulphur in a boiler
with 20 gallons of water, and boil
over a brisk fire for not less than one
hour and a half, or until the sulphur
is thoroughly dissolved. When this
takes place, the mixture will be of an
amber color; next, place in a cask sc
pounds of unslaked lime, pouring ovel
it enough hot water to thoroughly
shaken it, and while it is yet hot and
boiling, add the Is pounds of salt
When this is dissolved, add to the lime
and sulphur in the boiler and cook fol
half an hour longer.
When the necessary amount of water
to make the 60 gallons should be ad-
ded. When using it should be fire.
