ARE OF GREAT VALUE
They May Revolutionize and Sim
pIify Entire Method Of
Sugar Manufacture

At the meeting of the Hawaiian Sug
ar Chemist e Association yesterday the
most important point developed wal
that sugar milling practise is travelling
. at rapid rate back towards the re-
adoption of the diffusion process The
mechanical advances made through the
general use Of the Searby Shredder and
the Maesschaest Groove have simplifed
milling requirements. II was fully de.
veloped that the diffusion process has
advantages over the present intricate
system of half-milling and half,diffu,
sion. 49,. @-...i
Diffusion Plant Considered
TT was stated that the management
Of Pioneer Mill Company is now seri.
onsly, considering installing diffusion
process which has the manufacture of
white sugar instead of 90 degree raws
as its aim. J. p. Foster of Paia sum.
med up the case by saying that the diff
fusion process is simpler and cheaper
than milling. 90. "a
81 expect to see the diffusion process
again introduced in the near future be-
cause we are now in position TO re-
turn to it, y he said. DR.. H. p. Agee,
r. S. Norris and Horace johnson agreed
with him. p. Maesschaert said that

ton would be eliminated. s. s. Peck
said il would also result in throwing
out the filter presses, and no settling
tanks would be needed. J. p Foster
added that il would be a much cheap.

The Morning Program
The convention was called to order
yesterday morning by DR.. II. p Agee,
director Of the planters experiment
station and president Of the associa-
ton. Mr. Agee welcomed the dele
.. Ra{ss and. .iid that he hoped each had

OF thanks yes then given the trustees
Of the f, s. u A. for an appropria-
ton Of S2pGHRAt by them towards the
expenses of the convention. New Off
GERS were elected for next year, as fol.
lows; G.. Giacometti, president; H. 8.
Walker, Independent and 8, s. Peck,
secretary and treasurer. The old exc
cutiYe committee was reelected consist
ing of j. A. Verret, II. johnson, G. II.
Halden, J. E. Birla, A. Fries and r. s.
Norris.
Efficiency Defined
J. p. Foster of Paia then read his
paper on "Fireroom Efficiency" de-
fRing, efficiency as 1.-The state of per
lection we hope to attain next year"
His paper emphasized the necessity Of
having exact records kept of all FIRE
room performance and, what he said
was of prime importance, so arranging
that portion of the factory as to give
the greatest comfort and safety to the
laborers employed. He stated that the
amount of makeup water used is
gauge of the efficiency Of factory
work.
Another method of judging whether
satisfactory work is being done is to
watch the composition of the fue gases.
The discussion of this paper brought
out many interesting points. The per-
Torrance of oil furnaces and bagasse
burners was compared by II. L. Savage,
w. r. MeAllop and II. s. Walker and
t." question Of air supply to the FIRE
box.
Too Much Left To Chance
In answer to a question by Horace
Johnson Mr.. Foster said there are six
teen or eighteen automatic recording
instruments in Paia Mill. h. 3. Norris
discussed the use of "sweet waters
and said that these are not generally
used here because most of the eyapor.
ating apparatus in use is defective. He
also said too few recorders are used In
Hawaiian mills and too much Is left
to guess work. r.1 r. "a
Renton Hind thought recorders not
very important because unless located
in convenient places laborers would not
watch them. H.
7. Maessehaert said the fullest line
of recording instruments ought TO be
Installed in every factory, He said
that the "sweet water" ought to be
used. can boiler-tuhes pit, " he said.
"No one can help that, using sweet
water does not affect that problem. y
Boiler Inspection Needed .p''H"'
The difficulty of pumping super-heat-
ed water was then referred to by II.
Johnson. Renton Hind said there was
never any trouble if the pump is locat'
ed below the hot water supply with
head of three to nine feet
Boiler treasures were then discussed.
J. P. Foster said "safety first" must
be the rule, SO equipping the mill that
there is no danger to the lahorers.
There should be rigid laws enacted COM
