Oahu Sugar Company has built over
ten miles Of new permanent railway
and will be ready to care for a banner
crop in 1917 and 1918. The new fields
soon to be planted will bring yields up
to $1,000 tons. The Advertiser visited
the plantation last week in company
with five embryo plantation managers,
sugar technology students at the Col
lege Of Hawaii, and inspected mill and
helds, u.
p. Messchaert, chief engineer at Wal
phhu,. acted as guide. The party Of
students followed the cane into the
mill via the automatic unloader and
switching device and watched each
step In the process until at last the
finished raw sugar, baggetf, marked, and
weighed is loaded into cars. and starts
on its long journey TO the refinery, UP
the Hndson or on the shores Of San
Ffaheisc0 Bay.

The mill in its arrangement gives q
first impression Of simplicity aud com.
paethess. The plantation has really

dneing more cane than can be economic
ally handled IN the present plant. a
Mr. Messchaert said additions are
planned which. will bring up the bal
anee between the engineering and agfi,
cultural branches. The mill Is short On
power, the boilers and engine being be-
low the standard Of maximum require

tha' a minimum labor force is employed
aud in this particular Oahu mill is in
advance of many Of its neighbors and

Hig improvements Planned
The engine snd boiler capacity of

by shredder installed. Mr.. Messehaert
said the combination OF shredder and
grooved rollers has made cane milliAS
purely a question of mechanics
y The shredder first tears the cane into
n uniform, finely divided mass which
feeds into the first min in an eyeuly,
distributed, homogeneous blanket. Then

wetting a sponge and squeezing IL dry.
This can. be done three times, or SIX,
i is only a question of having enough
power TO do the squeezing and enough
steam to eyaPorate the maeeration wa
ter, he stated. ~
There are many special features about
this mill that are attractive, especially
that stated above, economical entrain-
ment to save labor. 1t is one Of the
eleanest and coolest mills in Hawaii.
There il no leakage or waste in any
part ofythe factory, the best possible
use being made of every pound of
steam and every unit Of power.
Tho Fields Inspected
After inspecting the factory a trip
was made to "Field AZ where n fine
stand Of d 1l35 was being harvested.
This cane is one of the best of the
early maturing new varieties, being
characterized by high sHerose content
and juice purity. 1t somewhat re.
sembles Lahaina in that regard. The
canes are small, very leafy and very
sweet, so while cane per acre is low,
sugar per ton of cane is higher than
in some Of the other varieties. Then.
too, ID f135 Is resistant to Lahaina dis.
ease and takes rather Kindly to irriga.

Great Work At Aiea n z. ,,.....-. =
Honolulu plantation mill was visited
next. fs4A II
This is a very old mill and gives the
impression of being overcrowded with
machinery. As a matter of fact the
work done has been highly satisfac-
tory to the shareholders, which in the
end Is the real test. Honolulu has been
money maker.
The Searby shredder was of course the
chief point Of Interest to those in the
party. Extraction has jumped from
ninety.fve, point something, to ninety,
eight, point something, in the few weeks
since the shredder started work on the
new crop, and it is not yet tuned up
to the full capacity. Starting at forty
tons per hour the speed has gradually
been increased and the machinery is
now taking care Of fifty tons. -. E.. 'm
The Ramsay Carrier .ss. -. 81
The Ramsay intermediate carrier is
doing great work supplementary to the
shredder. A suggestion made after
watching the way this carrier forces
the feed was that perhaps some in.
yentor may some day carry this idea
farther to perfection and devise forced
feed FOR a two-rOlIer mill. e. Kopke
said At the last mill engineers conSen.
