The Hawaiian Sugar Chemists As
ISOLATION met IN convention yesterday
morning at the Library Of Hawaii. Aft
er reports Of officers and other routin
business the delegates listened to tn
following papers:
J. +. Biela, FACTORY control; J. A
verret, glucose; G. 9. James, phos
phorie acid determination; y. t. Dill.
bingham, water aud volcanic activity.
II. +. Savage, boiling house recovery
Il T. Westly, electric drying ovens.
The subject of fboiling house re
coyeryv led to an extended discussion
ON the coordination OF scientific fel
cultivation and fertilizer experiment
10 chemical mill tests.
MIL Work Highly Scientific
AIohzo Gartley said that the mil
work is ON a highly scientific basis an,
that il is always possible to deter
mine definitely any results due to i'm
provements in methods. Tangibl
results. from experiments with fert
lizers and their effect on sucrose an,
purity are more difficult to determine
be said.
The chemists discussed all phases OF
this question and some method may BE-
worked out for checking up results
a result Of their attention having beer
drawn to this subject.
Volcanic Gases Discussed
Prof. y. r. Dillingham; review OF
the work Of Day and Shepherd, the
chemists who analysed the gases col
leeted from beneath the surface Of tn,
molten lava in Halemaumau, was re.
eeiyed with marked attention. As ha,
been previously noted these chemist,
discovered that the volcanic gases c)n'
tain an enormous volume Of water.
Their work seems to prove that the
water now covering so large portion
Of the earth 5 surface was originally
in combination with the mineral ele
ments in the interior Of the globe, AM
that the oceans are an effect and not
the cause Of volcanic activity.
Nitrogen Also Present
The analyses also demonstrated the
presence Of nitrogen In the bases, az
well as compounds OF potassium, Sodi
Jim, Calcium, Titanium, iron and sui
phnr. The rare element molybdenun
WIS QlhtONtIcu IN the IuOlttn AVA o.
the crater. There were no rare gases
discovered.
This paper win be published in full
in next Sunday s Advertiser.
The chemists will conclude their pro
gram today. The first two papers viii
be of general interest TO those engaged
In all branches Of the sugar industry
and large attendance is anticipated
Papers 10 Be Read
