The remarkable ultraviolet ray, a
demonstration of which Montraville
Wood and daughter, Miss Allene, at
the chautauqua Saturday night kept
the big tent in darkness for a period
of 18 minutes during which time all
manner of odd feats were performed,
proved as novel as it was interesting
and instructive, while the balance of
the program, including thorough ex-
planation and demonstration Of the
gyroscope and new submarine in
vention brought to an end an evening
which was by many said to be the
most delightful yet given at this
years chautauqua.
The lecture was anything but
learned, didactic discourse upon sci
ence. 1t was thoroughly within the
mental grasp of every member of the
audience, even down to the smallest
child and all proved their apprecia-
ton of the marvels of science which
were unfolded to them in a snappy
sprightly manner by remaining until
the end OF the performance.
After short demonstration of the
conductive powers of the human body,
in which sufficient amount of cleo
triclty was passed through Miss Wood
to light a cluster of incandescent
lights, the ultraviolet ray was taken
up.
Mr.. Wood explained the ray as
nearly as possible and told of it's i'm
mense value in the treatment OF can
Ger. As u means of determining, or
rather discovering, rocks which pos
sess radium properties, 1t is unsur-
passed. Mr.. Wood has travelled
through the United States, making
tests of rocks in all parts OF the coun-
try and has located those containing
radium In large quantities In Mis-
souri, and Colorado. These rocks,
when exposed to the ultraviolet ray,
turn a green and a blue color.
1t was explained by the lecturer,
during his demonstration, that sun
| light contains the ultraviolet ray,
but that this component part OF the
| light will not pass through window
glass. "If you want sun BATH the
speaker said, take 1t out-of-doors. "
Mr.. Wood has, after years of exper'
imentation, discovered substance
which, when charged with ultraviolet
rays, will act as a storehouse OF light
Ultimately, he expects to perfect this
to such state that rooms may be
papered with it and all artificial illum
nation done away with at night.
As an example of this process, Mr.
Wood charged various objects with
the ultraviolet ray and the same
glowed In the darkness, perfectly per
ceptible to every member Of the au
dience. Among other things he
wrote on the substance with the ray
the world light and the same coulC
he plainly read The children in the
audience were delighted with thD
ghostliite figure, on which the ray ma,
been thrown and which Mr. Woo
made dance about the floor.
An historical account of the disco'
cry and perfection of the gyroscop
was introduced by Mr. Wood who dr
played numerous models OF thl
queer, graHty-defying device. AS a
e interesting feat, he requisitloned Tn
services of two members of the al
G dience and made them endeayor
d force down an upright gyroscop
which travelled at a speed of ESQ
N revolutions minute. All the Weigl
81 tho men could press against the o
o iect failed 90 upset II and when NJ
G. Wood placed his fingers gently on Il
reverse sido and It followed the
=. course to the floor It was much
the amusement Of the audience al
