Many Valuable Suggestions.

cone of the large insurance COM
anies recently made an investigation
ninety-one thousand accident reports
nd discovered that ten per cent of
ae accidents were directly caused by
he lack of proper light, and in 1873
err cent Of the accidents poor light
lg was contributory cause. The
tatistics Of accidents in the United
tates reveal the fact that about dou-
lie the number of accidents happen
uring the four winter months when
he days are short as compared with
he four summer months when the days
re long, said c. w. Price of the In
ustrial Commission, speaking before
he Kenosha Safety Round Table
uesday night.
Efficient shop lighting is now con-
idered by progressive managers as an
indispensable part Of an efficient shop
quipment. Investigations by reliable
ave demonstrated that efficient arti-
ica1 lighting will increase the total
output of plants such as steel mills,
wo per cent, and textile and shoe fac
cories ten per cent. The cost Of eff
icient shop lighting is from one-tenth
TO one-half of one per cent of the
wages. For instance, if man earns
three dollars and fifty cents day it
would cost about cent and a half
&c furnish him with adeqate light"
he continued.
''The orders of the Industrial Com
mission require that for ordinary de-
partments where there is no smoke or
gas, there should be provided one
fourth candle power per square floor
foot. That is, a 100 candle power
lamp hung ten feet from the floor will
illuminate four hundred square feet of
floor space. For foundries, one-half
candle power is required per square
floor foot. On machines, where fine
work is being done, sufficient light is
required to avoid eye strain.
MIR. Price recommended the lungs
ten lamp as the best type of lamp for
all shop conditions. He was particu-
Jar to state that tungsten is not
trade name and these lamps are not
monopolized by one company, but are
manufactured by a number of com
panies which are in sharp competition.

almost the same color as sunlight and
IL very cheerful and pleasant in it's
effect. The modern tungsten lamps
are very durable; the life ranging from
1000 to 1000 hours
e'The tungsten lamp consumes only
one third to one-fourth as much cur
rent as the old type of carbon flament
lamp which is so commonly used in
factories. In the average factory the
old type of lamps can be replaced with
new lamps and the light can be increas-
ed three or four times, with no addi-
tional cost for current. -
Mr.. Price recommended the shallow
bowl reflector as the best design for
efficiency. These refectors should be
made of white porcelain enameled
steel. This material is very durable
and strong and is easily cleaned. A
properly designed reflector adds from
thirty-fve to fifty per cent to the ef
fciency of the lamp. This is an ex-
ceedingly important point for every
manufacturer to bear in mind.
The above type of reflector does
not waste the light upon the ceilings
and the upper walls, but concentrates
It upon the working plane where
Il is needed.
Mr.. Price emphasized the import
snce of keeping the refeetors clean,
saving that clean reflector is twenty
FIVE to fifty per cent more efficient
man dirty reflector.
The tungsten lamps should be so at
cached in the reflector that the center

hat in the average factory department
here the one hundred watt tungsten
mn is used the cost is about FIVE dol
IS Der unit. This includes lamp, re-
actor, material and labor. The larger
its used in foundries cost about
,enty-fve dollars per unit, including
aterial and labor.
Mr.. Price gave the following stand

conditions in,. factories. T. In rooms
