DOES HIGHER EXTRACTION MAKE
UP FOR BIG OPERATING COSTS?

!, and filtration of saccharine juices, Con
sequently descriptions OF methods and
apparatus designed to clarity and pu.
rify cane juices are not essential, but
/ a few comments founded on well
known facts may lead the thoughts of
all interested in the art of sugar pro-
duction to obtain better results with
out becoming deeply involved in sci
entific chemical research or higher
mathematics -: ~. ~:
"As is well known, the art of clarifi.
cation of cane juice is partly chemical
and mainly mechanical, consequently
the most important branch OF factory
operation rightly falls outside the do
main of the engineer. -. ::
Easis Of Endless Trouble. ....'
yet the engineer should be privi-
legged to take an active interest in the
process as it falls within his province
to provide the means whereby the
sugar-maker produces results for faul-
ty treatment of cane juice is the basis
of endless trouble in a factory which
has to be relieved by the engineers
staff. We of Hawaii have about as
difficult problem in the treatment of
cane juice as can be found in the cane
sugar world, due largely to the fact
that we raise abundant yields per
acre by the aid of artificial fertiliza-
ton, also our cane lands are located
in almost every variety Of physical
and climatic conditions" =.
After this preamble, Mr.. Truscott
then stated that he thought that large
ly owing to the variety Of conditions
which have to be met by all who treat
of sugar in Hawaii, to consider all OF
the juices which enter factory as a
standard product The report went
into many interesting details of the
treatment of the juice to clarity 1t.
Ingenious Hydrometer Jar. -. i
Mr.. Hind submitted description
of a hydrometer jar made of 2 inch
brass tubing sealed at one end by a
heavy brass plate, The open end OF
the jar is Tipped and the top end at
the mouth Of the Jar is beveIled OF to
a fairly sharp edge, The depth Of the
lip is SUFFICIENT to give a constant
error in the reading of the hydrometef
of about $40 of a degree: With the
higher extractions which are now
being obtained with the mills. the
juice from the final discharge roll is
SO low in density that It is difficult
to get an exact brix reading owing
to the influence Of the meniscus, but
by the use of this jar sighting across
the top edge, an exact reading of the
spindle can be obtained to which read.
ing constant correction can be OBJ
tanned.
.aThis device has been Iii use IN me
Eva Mil for two seasons and has en-.
abled the laboratory stan to obtain
fairly constant last MN Juice purities
because Of the accuracy with which
brix. readings Of les, than unity can
be made This device IS not patented
and the design is oMered to the plan
tation laboratories GRATIS"
Have Gone to Pearl Harbor.
After the morning session the con-
vention left at 1:45 on special train
for Pearl Harbor to inspect the equip
ment of the government machine
shops. Tomorrow morning at the
convention win convene again to hear
several important papers, among othS
ers two on sugar room machinery by
c. White of Kilaueg and William Wyl-
lie of Onomea.
