How 20 Avoid Accidents
To avoid accidents during the VIM
ter months by keeping the factories
well lighted was another phase Of cleo
tricity touched upon by +. ?. Gibson
Of Cation, Neill & CO. More aeci-
dents occur during the dark months
Of winter than in the summer, ne

that there is plenty OF light. Nc
Cubbin OF Pioneer said his men liked
the mercury lights, while Cowan OF
Wailuku favored the nitrogen lamp,
and Renton of Eva flaming arc lamps
with frosted globes.

rlace is for bleeders, it depending
mostly on where the steam Is ad-
mitted.
A. G.. Bulge read a paper on fire
tube and water tube boilers and oil as
4 fuel, which was IN part as follows:
Fire Tube vs. Water Tube
THE year has seen radical change
in the selection Of boiler room EQUIP
ment for sugar factories. This has
been marked by the recent purchase
of several installations Of water-tube
boilers to be used In conjunction with
bagasse-burning furnaces. There are
several reasons for this departure
from the old style tubular boilers.
among which may be noted the fol-
lowing: safety, high pressure, In
creased life Of plant, decreased MAIN
tenance, but slight difference In first
cost for corresponding pressure, per-
lection OF design Of this type of boiler,
excellent steaming qualities, ease OF
cleaning, economy, independent struc- |
tural supports. etc
The factories IN general are at |
present equipped with old horizontal
return boilers on which the maximum
pfessures carried are necessarily very
low IN the majority of cases. these |
boilers have been operating at or |
near the pressure for which they we're |
designed, for from fifteen |
to twenty-five years. This makes the
continued operation Of these plants /
positively dangerous. as can be affirm
ed by the experience of all other sec
tons Of the world with similar install /
lations. Fortunately, no serious acct
dents have occurred in this territory
to date, but each year the possibility |
of this record standing another sea-
son is diminished and the danger cor
increased.
sThe danger Of serious accidents !!
and the question or safety are worthy
OF considerable thought By All mill
owners and engineers. as the directI
responsibility FOR an accident or loss /
OF life and the consequent shutdown /
Of the factory IN the grinding season /
rests with them
suo1estt Important Changes
There are two important changes /
which can be made which win 90 far
toward eliminating al danger from
this source. The first and most I'M
