Subjects Are Discussed in
First Days Session

THSt LAY > SCSolOH -
Over 100 strong the mill engineers
OF Hawaii under the auspices OF the
Hawaiian Engineering Association met
this morning at the Library Of Hawaii
for the fret session OF the convention,
which will last until Wednesday.
At $3.50 Chairman e. v. Anderson
called the meeting TO order and after
saying a few words OF welcome gave
the chair to A. Gartley. who will pre-
side over the meeting today.
The subjects read and discussed
this morning were Field Machinery,
Boilers and Furnaces" and "Lubri.
cation" and this afternoon the pa.
pers were JElectrification% and
'fEvaporators and Pans 49,. .
This evening all the engineers and
their friends viii go TO the Biiou thea

Sunday morning 60 engineers and
their guests, the chemists, spent q hi

In taking up the first paper, Field
Machinery" A. Gsrtley emphasized
the point that all such machinery
should be simple, both as TO constrnc.
ton and operation. and the discussion
mostly conferred about the best kind
OF plow TO use in different ground
with the caterpillar engine, especially
where trash has 10 be contended with.
II was the opinion OF most that al
present no pillow had yet been made
which worked satisfactorily with the
caterpillar. but the problem was now
being worked on. r. Renton Hind
told about device which was being
developed for the conveying OF sugar
cane from TIE fields to the perna-
.nent fumes, and which, he hoped. TO
have ready for use in few months.
machine to load cane into the cars
AZ a rapid rate was being worked out,
n was announced by II. L. Freeman.
In discussing his paper, Boilers and
Furnaces" A. @. Bulge said that
many changes had been recently meoe
IN boiler equipment. resulting IN the
controversy over which is better, the
water tube boiler or the fire tube
boiler.
Bulge claimed that the water tubes
were superior. That while they might
cost a third more, they were cheaper
IN the long run and we're far safer
from explosions. The main point In
their favor, however, was that they
were built to stand a higher pressure
of steam, and as the higher steam
nressure IL fast coming into use, II
will soon be necessary for the planta'
lions to install them.
The question then came up over the
ceyolpment Of steam, and r.. r.
Hind said that he had had one OF both
kinds installed and found that he
could get more steam in a given tine
with water tubes than with fire tubes.
Recently many of the plantations
have Installed three-inch tubes in the
boilers and comparison was made be.
tween them and the f0urinch tubes.
Some OF the members declared that
they had been satisfactory. while
others found they became choked with
ashes and the circulation was poor.
On the topic of boiler settings Hind

ported on independent steel frames
and not rest on the brick work, the
contention being that IL the boiler
rests on, the brick work the latter is
likely to crack II was declared.
however, that II expert masons were
employed, large percentage Of the
cracks would not occur.
That q systsn whereby the boilers
on the plantations could be inspected
every year and that II was really
necessary to have inspection to avoid
all chances OF explosions, was said by
w. g. Hall to be imperative. He pro-
posed that an expert be brought down
from the mainland every year.
The next. question under the subject
OF boilers was the testing of water and
the consensus OF opinion was that
compounds were of little use and often
harmful. Many Of the members, how
ever, said that they had used differ.
ent makes OF compounds and found
them Ideal In keeping the tubes clean.
Water softeners and other methods of
preventing scaling were compared and
ways OF employing them discussed.
