METHODS DISCUSSED
By SUGAR EXPERTS.
Engineers and Chemists In Joint
Is Sessions Hear and Debate
On important Papers

More than seventy members of the
Hawaiian Mill Engineers Society and
the Chemists Association met In two
joint sessions at the Library Of Hawaii
yesterday to debate matters Of impor.
tanee to the sugar industry of the Isl.
ands- The afternoon session covered
classification and Filtration,n and
"Eyaporation and Sugar Boiling, -
while that in the morning was on
TMilling" and "'Fireroom Efficiency .
SAMUEL y, Peck, OF Alexander 4 Bald.
win, acted as chairman for the after.
noon meeting and W. G.. Hall, of the
Honolulu Iron Works, presided in the
morning. n
/ Three papers by Thomas Murray,
chief engineer of the Paauhau Sugar
| Company, Hawaii, and chairman of the
committee on Qualification and filtra-
ton; Ernest Kopke, president of the
Kopke Clarificr Company, Ltd, and 3.
y. Peek, respectively, were read at the
opening Of the afternoon session, and
were later on debated by the delegates.
Filtration and Qualification p 'fa
II was pointed out in the COMMITTEES q
report that filtration is more of a me-
chanicai process than Qualification.
Juice strainers, mud presses, bagasse,
excelsior and sand filters come under
this heading. A great deal has been &C.
conplished in the defecation of the
juices along these lines in the last few
years, the report adds. This part of
the work is more in the engineers line
of the business than treating the juices
with lime, sodas' and other DELEGATION
agents, for this part is wholly left to
| the chemists. -. tG.4ti
| The report on Evaporation and Sugar
Boiling was next taken up, two papers
being read on the subject; one by
George Duncan, chief engineer of the
H0laa Sugar Company, olaa, Hawaii, and
the other by G. Giacometti, chemist of
the Olaa Sugar Company. ,"aI
In these reports it was stated that
the only new feature in evaporation
that has been found is the automatic
i level control at Onomea; a feature
which seems to be very little used in
this Territory, although the reports
added, 1t is very important one.
Among other things it was, said that
a HLillie evaporator will not work
IL one of the level controls gets out of
order, so it would seem that If "Stand-
ards" were fitted with automatic con-
trolls they might improve the quality
and amount of work done by these eva
poratOrs. ,.f'
Milling '.t
A. Kraft Of Waipahu, and chairman
of The committee on milling, read pa
per at the morning session. The re-
port dealt with the result obtained
from the installation of new mill ma
chinery, such as shredders. A number
of letters from mill engineers cited adj
vantages and defects in the use of new
machinery, and the best procedure to
was the topic debated.
Efficiency. In this paper the commit
tee strongly urged The adoption Of a
universal boiler inspection, which was
generally favored by the delegates. 1t
was added that the ultimate end Of
| fireroom efficiency should be to gener-
ate enough steam for the factory re-
auirements at the lowest cost, e.. .
10 Give Demonstration -
1t was announced yesterday by Carl
Andrews that ON Thursday a demonstra.
ton of machine to produce fuel and
Illuminating gas frop gasoline will be
performed for the chemists and engi-
neers. They win also examine the new
coalng station at the Inter.Is Island Com
pany at half.past one o clock. A boat
has been chartered to carry the dele.
gates across the harbor. .... ~:
"Glucose Determination and "In.
version Methods" are the subjects
down for discussion at the session
which commences at halfpast eight
this morning. In the afternoon gen
eraT topics and agricultural chemistry
will occupy the delegates attention.
