ELECTRICITY VS. GAS
--------------------
Former is Cheaper Than Gas
at the University

THE COST OF OPERATING
-----------------
The Plant on the Campus is
$4,700

The Cost to Light the University
Buildings and Campus with Gas
would be about $3,500 More.--
Itemized Statement
--------------------
When the regents decided to light the
university buildings and grounds by
electricity instead of gas, they not only
made a big saving as over gas, but
they also secured better lighting. In
order that the exact cost of operating
the lighting plant may be plainly seen,
the Daily Argus today publishes an
itemized table of the cost. The total ex-
pense connected With the lighting plant
or rather the cost of lighting is $4,-
700.75, whereas it would cost approxi-
mately to light with gas about $8,500.
LABOR.
One engineer at $750, one engineer
at $700, one electrician at $600; total .
$2,500.
INTEREST AND DEPRECIATION.
The cost of engines and generators
$5,000; cost of switch board $900;
cost of feeders and all wiring $20,000;
cost of piping $800: boiler plant
$4,500; total cost of plant $31,200.
COST OF OPERATING.
Depreciation on engines and genera-
tors, $5,000 at 5 per cent, $250; on
switch board, $900 at 2 per cent, $18;
on feeders and wiring, $20,000 at 2
per cent, $400; on piping, $800 at 2
percent, $16; on boiler, 1/3 of $4,500
at 10 percent, $150; total $834. In
the last item the boilers are only used
1/2 of the lighting.
Interest on investment at 4 per cent
$1,128. Lamp renewals, 500 lamps
at 25 cents, $125.
COST OF COAL.
The coal burned under high pressure
boilers is about three tons per day.
One-third of the steam from high pres-
sure boilers is used for other purposes.
Hence we have about 700 tons of coal
to charge to the electric plant, and as
the steam is used for heating we have
only 25 per cent to charge to the light-
ing plant which is 175 tons at $2.25
per ton. This brings the cost of coal at
$393.75
LAMPS, MOTORS ON CAMPUS.
The incandescent lamps, arc lamps
and motors installed on he campus are:
Motors 100, H. P. at an average effici-
ency of 80 per cent, equals 93,250 watts;
about 30 are lamps at 19,800 watts;
total 13,050 watts. This will equal
1884 incandescent lamps. The actual
incandescent lamps installed, 5,000, plus
the 1884 incandescent lamps, make a
total equivalent of incandescent lamps
of $6,884.
COST OF OPERATING PLANT.
The average work actually per-
formed by the plant amounts to about
150 amperes at 220 volts, 24 hours
power day as follows:
Plant is shut down every Sunday also
all of July, August, September, mak-
ing in all 234 working days per year.
Thus 150 amperes 220 volts x 24 hours
x 234 days divided by 1,000 watts
equals 185,328,000 K. W. hours. This
would make the cost per K. W. hour
$.0254, and the cost per lamp per
hour sixteen-hundredths cents.

Luella Davis Dead.
Luella B. daughter of Mr. and Mrs.
Frank K. Davis died at the home of
her uncle George D. Bunn, of Superior,
May 14, 1899, aged 14 year, 7 months.
She was born in the township of
Salem, Oct. 25, 1884. Always being
in good health, her sudden death was
a great shock to her many friends, her
sickness lasting but two weeks. Al-
ways being of a cheerful nature and
full of mirth, won for her many friends.
Angels came and claimed our darling;
Carried her soul to realms of bliss;
Though we would not if we could
Wish her back to a world like this.
With this World's trials and troubles,
Now her heart won't have to bear;
With her angel Sister she is waiting:
For her love ones to meet her there.
It seems hard to part with our loved ones,
For the grief seems hard to bear;
But with steady hope we are waiting
For some day to meet her there.
