How tho World. Fair VIII he Lighted

a sight more beautiful than the
Worlds Fair at Jackson Park will DC
at night cannot be conceived, so lib
cral vii! lie tho use of electric lamps
! and so artisticaly are they arranged.
For illomlnating the grounds and
entrances to the buildings lamps to
the number Of 1850 are placed at IN
tervails of from sixty-fvc to seventy
five feet, except at the extreme south
eastern part of the grounds where
distances between some of the posts
is increased to 123 feet Around
the main cntcranccs to the principal
buildings clusters of lamps will be
placed. The arc lamps employed for
exterior illumination will be support
ed on ornamental posts, designed to
receive one, two, or three lamps, and
where cxpcdicnt to have arm support
ing incadcsccnt lamps of high candle
power, inclosed within colorcd glass
lanterns that will afford richl V dec
orative effect. 4 problem of different
character was presented when the
question of ailse lighting with arc
lamps came up, owing to the varied
nature of the exhibits, the character
of the enclosures, the height Of show
cases, proximity Of supports, and these
have not yet been determined, owing
to the withdrawals and changes in
the various locations of exhibitors.
In the final allotment Of lamps in
round numbers 1900 were ASST yncl
to the manufacturer building, 500 to
the agricultural building and annex,
$50 to the transportation building
proper: horticultural building, $50;
mines and mining. 200: the fisheries,
80, and the Illinois builnig, 81.
These will all be supplied with cur
rent by the exposition company from
the power plant, as will also some
$50 arc lamps required in machinery
hall. In addition to this last $50
there Will be a greater number sup
piled by few of the leading eXhib-
itors under contract, who will also
supply the arc lamps required in the
annex to the transportation building,
in the forestry building, pumping
plant, and the choral building.
Special lighting effects will be secur-
ed in the great glass dome Of the hor-
ticu(turc building by suspendins
from the trusscs fifty arc lamps in
three circular rows, having ten in the
upper and twenty each in the lower
rows.
\ problem of different nature was
encountered in lighting the mammoth
manufacturers building, owing to the
unusual height of the arches and the
great area requiring illumination.
The plan deemed the most practical
promising the best results includes
five circular clcctroliers, four OF
which are sixty in diameter, and the
center one one scventy-iivc feet, built
Of an angle iron and suspended from
the arches. Here the lamps will be
40 feet above the floor and forty to
sexenty feet below the roof. The
clectrolicrs are suspended by means
of steel shaft securely bolted to a
bridge passing across the center OF
the circle, bridge and circle having a
footpath three feet i'll width and
guarded by a suitable railing, along
which the carbon thinner travels
when carbonizing the lamps, the
trimmer ascending one of the big
arches to the supporting shaft and
then descending by means Of a ladder
attached to the latter. The four
smaller elcctroliers seventy-fve arc
lamps will be suspended, and to the
large centerpicce 100 arc lamps. the
lamps being hung in pairs and sus-
tanned by cords passing over nsulat-
cd pulleys, each balancing the weight
Of its mate.
