growing recognition Of the
- importance and value of proper
lighting arrangements for the COM
fort and health of the people. The in
creasing number Of large buildings
in which the supply Of natural light
even during the day is not sufficient
for the needs OF those occupying
them, calls for constant development
in artificial lighting, which is now
being studied in a scientific manner.
Every progressive business man is
now able to measure in actual dollars
and cents the value OF his lighting
system in the amount of comfort il
contributes to his customers and en-
ployes.
The real secret Of popular illumi-
nation is its subueness. It is felt
almost uncOnsciOusly. People are apt
to shun a place that Is too glazing
or that is tnsuffioiently lighted The
effect of bad lighting upon those who
are compelled TO submit to il is def
nitely recognized By any one who
pays attention to IT. Harsh, glazing
light affects sensitive nerves like IN
pleasant noises. Those who are com
PEELED to work in a glazing light are
subjected to quite as severe a strain,
of a different kind, as those who work
in insufficient light, and the optical
effect may be equally bad.
This has become so well recognized
that the illumination Of a large room
or building IS carefully studied with
a view to its demands in light, and
me Illuminating engineer finds his
INDOOR ughtlng problems frequently
more troublesome than those out OF
doors because il may involve conflict
with architectural conditions One of
the largest publishing firms in the
country, which is noted for its con-
sheraton Of its employees, has lately
moved Into building specially con
sJructed Tor its work In this, the
subject OF Illumination received first
consideration. A committee of five
persons, including a skilled oculist
and an Illuminating expert, were
called into service and they made a
number Of experim ents as to the diff
Ierent kinds OF lighting best suited
to the work to be carried on in the
different rooms. The employees were
also consulted. Among the expert
ments were tests, two weeks in
length, Of different lighting systems
These votes were unanimously in Ia
vOr Of indirect lighting, which has
been adopted in such a manner that
this new building has been pronounced
by experts to be the best lighted in
the world for its purposes
Importance Is Recognized.
The propr1etors OF places OF public
resort and amusement now recognize
the Importance Of the lighting OF q
hotel or theater as almost equal to
its ventilation and the greatest care
IS taken to insure its perfection One J
OF the finest hotels in Chicago lately
has opened a new dining room which
IS known as the com plexiOn room"
because Of the beauufying effects of
Its lighting system. 1t is needless to
say that it is in much favor for fash
lonable parties. The room is enor-
nous and is furnished in Louis XVI
style and the novel and original man 4
ner IN which its illumination problem
was solved viii no doubt be widely
copied. Instead OF being suspended
from the ceiling, the lights are placed
in large urns similating deliberately
carved white marble. These urns are
seven and a half feet in height and
each contains four large Tungsten
electric lamps with special silTered
retlectOrS- The urns conceal the light
from the direct line of vision but
throw il up against the light ceiling
from which il is reflected throughout
the room The ceilings and walls Of
this room are Of ivory and gold and
the draperies are OF American beauty
red, but its peculiar charm is entirely
due to It's unique and elaborate light
ing arrangement
AS electricity is now the rnosr FREE
quent basis Of illuminating problems
eieculc nights naturally receive most I
attention and there are improvements
IN the different forms of electric
ngnts being made each day The IL
Eliminating engineer recognizes four
instinct methods Of lighting a room.

some particular purpose and some {

effects.
Concealed illumination.
Concealed illumination is the form
IN winch the source Of light is en-
Irely hidden from view and the light I
thrown directly upon the objects 10 /

5nop windows and show cases and for /
Lootights on the stage. Indirect light |
Is the form in which the source OF I
lBnt Is hidden, but the light itself is
thrown to the ceiling to be reflected I
and diffused by the ceilings and walls. /
Ihis method is employed in many 1
work rooms as well as in restaurants, !
lneaters and public halls It's great I
advantage is the restfulness Of having I
no brilliant glare OF exposed lights I

Indirect lighting is possible only I'm /
rooms having light colored ceilings I

sense, indirect lighting must be con- I
