othing. In fact, it is not surprising
to find that occasionally the elimination of daylighting--the reliance
upon artificial light alone--has been seriously contemplated. When the
possibilities of the latter are considered, it is reasonable to expect
that it will make greater and greater inroads and that many buildings of
the future will be equipped solely with artificial-lighting systems.

Naturally, with the tremendous development of artificial light during
the present age, a new profession has arisen. The lighting expert is
evolving to fill the needs. He is studying the problems of producing and
utilizing artificial illumination. He deals with the physics of
light-production. His studies of utilization carry him into the vast
fields of physiology and psychology. His is a profession which
eventually will lead into numerous highways and byways of enterprise,
because the possibilities of lighting extend into all those activities
which make their appeal to consciousness through the doorway of vision.
These possibilities are limited only by the boundaries of human endeavor
and in the broadest sense extend even beyond them, for light is one of
the most prominent agencies in the scheme of creation. It contributes
largely to the safety, the efficiency, and the happiness of civilized
beings and beyond all it is a powerful civilizing agency.

THE ART OF MAKING FIRE

Scattered over the earth at the present time various stages of
civilization are to be found, from the primitive savages to the most
highly cultivated peoples. Although it is possible that there are tribes
of lowly beings on earth to-day unfamiliar with fire or ignorant of its
uses, savages are generally able to make fire. Thus the use of fire may
serve the purpose of distinguishing human beings from the lower animals.
Surely the savage of to-day who is unable to kindle fire or who
possesses a mind as yet insufficiently developed to realize its
possibilities, is quite at the mercy of nature's whims. He lives merely
by animal prowess and differs little in deeds and needs from the beasts
of the jungle. In this imaginary journey to the remote regions beyond
the outskirts of civilization it soon becomes evident that the
development of artificial light may be a fair measure of civilization.

In viewing the development of artificial light it is seen that preceding
the modern electrical age, man depended universally upon burning
material. Obviously, the co
