ir beauty and symbolism have been appreciated at night by
many persons who do not notice them by day. Not only are the beautiful
structures of man lighted permanently but many temporary effects are
devised. Artificial lighting effects have become a prominent part in
outdoor festivals, pageants, and theatricals. Candles have been
associated with Christmas trees ever since the latter came into use and
naturally artificial light has been a feature in the community Christmas
trees which have come into vogue in recent years. The Municipal
Christmas Tree in Chicago in 1916 was ninety feet high and was lighted
with projectors. Thousands of gems taken from the Tower of Jewels at the
San Francisco Exposition added life and sparkle to that of the other
decorations.

After the close of the recent war artificial light played a prominent
part throughout the country in the joyful festivals. A jeweled arch
erected in New York in honor of the returning soldiers rivaled some of
the spectacles of the Panama-Pacific Exposition. The arch hung like a
gigantic curtain of jewels between two obelisks, which rose to a height
of eighty feet and were surmounted by jeweled forms in the shape of
sunbursts. Approximately thirty thousand jewels glittered in the beams
of batteries of arc-projectors. Many of the signs and devices which
played a part in the "Welcome Home" movement were of striking nature and
of a character to indicate permanency. The equipment of a large building
consisted of more than five thousand 10-watt lamps, the entire building
being outlined with stars consisting of eleven lamps each. The "Brighten
Up" campaign spread throughout the country. The lighting and
installation of signs and special patriotic displays, the flooding of
streets and shop-windows with light without stint, produced an inspiring
and uplifting effect which did much to restore cheerfulness and
optimism. A glowing example was set in Washington, where the
flood-lighting of the Capitol, discontinued shortly after our entrance
into the war, was resumed.

In Chicago a "Victory Way" was established, with street-lighting posts
on both sides of the street equipped with red, white, and blue globes
surmounted by a golden goddess of
