ngInsers Must Have Tools
Mr.. Kopke said recording instru
ments are needed TO weigh and meas
ure all materials passing through any
part of a factory, and compared mill
practise with grocery store methods
In the mill there is much guesswork OF
the kind that would bankrupt a mer
chant. .- a.
of the highest economy is wanted
we must measure and weigh. II il up
to the engineers TO make il plain to
he owners OF the plantations that II
their employers Rre 0oinn 20 hold them
to strict accountability they must have
the proper tools TO make exact records
possible" he said. Furthermore, IL
is up to the engineers to show by their
records that the necessity for these
tools exists,
One Use Of Scrap Pie
Commenting on Wilson's comparison
Of fortunate and unfortunate engi.
nrers X. Renton Hind told about Pho.
ueer 3 scrap pile. The money the man.
ager gets from the sale of second ha nd
machinery and used steel and iron goes
i"to a snecial fund at the disposal Of
the engineer for the purchase of new
"iler tubes and recording instruments.
Mr.. Kopke thought this an excellent
idea, and advised every engineer to
start a scrap-heap. Charles Cowan said
no one has yet invented a draft gauge,
hut otherwise the recorders at Waikiki
aIe all giving satisfaction.
What to do with the records, how to
make and how to use them, evoked con
siderable discussion. Mr.. McCubbin
said put all the data relative to each
chart on the back Of the chart. Mr..
Cownn said keep the charts on view or
where they can be readily exa.
for comparison of work. Mr.. WylL,
thought daily charts could not be tab,
ulatcd without too much waste of time
by the engineer, but perhaps the sugar
boiler, or chemist, could hnd the time.
Put One Man on the Job
This brought n reply from Mr..
Ropke, who said this work is of sufi.
cient Importance to put one man on the
Job, an extra man whose sole business
should be the handling Of the gauges
and recording instruments, and the
of daily charts. He spoke
Of the extreme Importance of knowing
what is being done while each process
= going on, and deprecated the shoul.
dering of this work on any one of the
present mill staff. al advise you all to
save more scrap iron and buy more of
these instruments Of precision" he
added, land hire a man to attend to
them"
Mr.. McCubbin described his new
steam flow meter, and a German make
now unobtainable on account of the
war, where the gauge itself is moved
about from one steam line to another
and attached to permanent offsets in
the pipes. This herman gauge deter
mines currents, pressures and the vol
nme of moisture passing through the
line. o.
al intend to find out exactly where
steam is being wasted in Pioneer mill
during the 1917 grinding season." he
added.
The Best Paper Last
In taking up the report on heat con.
SeTvation in cane sugar factories
chairman Hind said he had found the
subject most fascinating one because
II covers the entire field of sugar mill
ing, as heat conservation begins at the
cane carrier and ends where the An
ished bag of sugar leaves the mill. He
said that this report is much of IL
purely elementary, going back to the
basis of textbook definitions. Some
Of the work is original and some com
piled from standard sources.
al want you to take this report
home with you and come back a year
from now prepared to discuss and crit
eize it," he said. Mr. Hind then
passed hurriedly through the report by
sub titles. Beginning with "defni.
tons, he commented on each of the
Iubjects embraced. The "appendix "
contains tables on equivalent values of
and mechanical units, and
of saturated steam, all re.
duced to terms directly applicable to

Where to Save Heat
His resume of conclusions reached as
TO where heat units can be saved fol.
lows:
"In summing up we see that con,
iorvation of heat may be effected by
attention to the following details nj
he various stations in a cane sugar
factory:
Mills. Reduce power demands to a
minimum.
Use hot water for purposes of macer'
alton. 60.
Reduce moisture content of bagasso
o the lowest possible point. .
Ash Pits. Reduce quantity of un.
burned fuel passing through the CRATES,
Furnaces. Keep air supply at mini
mum.
Prevent infItration of air through
settings,
3 Prevent radiation losses and air
d traits in fire room.
Boilers. Keep heating surfaces
clean, both on fire and water side.
