Day has ever been regarded as the |
natural season of business activity. and
right the period of rest; but the constantly
changing conditions of the worlds busi-
ness and social relations have caused the
former to ereroach upon the latter. and
we are thus forced into making proper
provision fol meeting such existing
conditions by more general aud effective
illumination of public thoroughfares.
which may properly be defined as that
character Of lighting which in our
advanced stage of civilization has be-
come absolutely necessary for public
convenience and police protection. under
the two essential conditions of efficiency
and economy.
The volume of light necessary for the
proper illumination of public thorough
fares must depend to a greater or less
extent upon the general character of the
territory to be lighted and the purpose
such lighting is intended to subserve.
| Que general system of illumination may
be best suited to country villages and
another to metropolitan cities; One to
suburban territory. another to residence
districts; one to business centres and
still anotger to congested districts.
| But whatever system. agency or
character of lighting may be adopted it
should be such as to afford absolute
uniformity of light over the entire surface
of the street to be lighted. In other
words. the comparative serviceablity of
any system adopted must be based. not
upon the intensity of the initial power,
but upon its divisibility OF source and
uniformity of illumination.
The degree of public dissatisfaction
with electric street lighting is now not
only evidenced by general complaint of
ineffectveness, but by protest. We may,
therefore, commend the opinion of VIM.
NJ. Slime. who. in the Electric World of
Febru airy 23rd, says: I'm view of these
recited facts. is little to be wondered at
that the arc lamps. as ordinarily operated.
are probably the most unsatisfactory
means of illumination now in use. THE
incandescant electric light. because OF its
Inherent defects. lighting power, and
excessive cost, is totolly unsuted for
street lighting purposes. while gas still
stands the unchallenged leader of all
Illuminating agencies. Science and
inventive genius combined have brought
about revolution in form of its most
perfect utilization for street lighting
purposes by the use of Welsbach
mantels.
THE ADVANTAGES OF THE IMPROVED wells
BACH SYSTEM OF STREET LIGHTING
!, The great points in the use of the
Welshbach system of street lighting may
be briefly summarized as follows, namely
Ist. The equal distributor of the
light over all portions of the area illuml
mated.
| end. The beautiful and attractive
character of the light being a pure whits
, light, unaffected by change of tempera
ture or winds or other natural distur
Dances.
. 3rd The absolute immunity from
Pickering or smoke, III the lantern.
4th. The high candle power of the
light.
!, sth. The perfection of the service
rendered. Being attended to by efficient
labor, the lantern and entire equipm enl
are kept cleaned and IN first class order
at all times.
9th. Its great economy over any otheI
method of street illumination.
