Four of the greatest wonders IN -.
scientific world were described in 4.
tail to an audience that packed C.-
hall on Tuesday evening when Prof.
scr Montraville NJ. Wood, a scisr.s.
and inventor well-known througbop,
this country, gave demonstration IA.
/ lures upon the gyroscope, the mona
rail car. the ultraviolet raw and ~.
human torpedo" with ITS mechar,os,
ears" to detect the sound of a 60,
moving in the ocean. 1t was by f,r ~
of the most interesting of the nroora ~
given in the Augusta Entertainr.ns
Course. and the lecturer professas
Wood, and his charming daush,.
Miss Allen M. Wood. his co-worker ava
assistant for many years, held ,h.
close attention of their audience g.
over two hours with their marve,n,.
demonstrations.
The ultra violet ray which profess..
Wood demonstrated first in his lec,r..
is produced by taking alternate cur.
rent and boosting it up to $4,000 volts.
requiring one of the most danperou,
currents known today.
The audience saw large disks coa,.s
with radioactive materials chang.
their color when subjected to this WON
derful ray and noticed that some =,
these colors when rapidly spinninr
would not blend. The power OF th,s
ray to store up light was demonstraf.
Led by the lecturer and with this rav
|he made a picture" Of his daurhter
Which reminded one somewhat OF =
shadowgraph. and this held its light for
q long time after 1t was made. And
with this magic ray Professor Wood
wrote upon large sheet tho word
light" which the audience could
plainly see at close range for soma
time after the ray had been taken
away.
The gyroscope was next demonstrated
by Mr.. Wood and to assist In this dem.
onstration three young men from the
audience went onto the stage. The lee.
turer first showed the principle OF the
gyroscope with a large one which he
manufactured himself. He then intro.
duced the wrestling gyroscope, which
measures "a inches in diameter and
weighs y pounds and is capable OF throw.
ing 2oo-pound man If he persists in try.
ing to handle it. The gyroscope was Del,
in motion and placed upon the floor
standing on edge. and try as hard as he
might no member of the committee was
able to tip it over on its edge. Yet the
gyroscope would lie fiat when directed
by the lecturers finger. The gyroscope
was then applied to the airship and the
monorail car
AS a special feature of the evening Mr.
Wood gave demonstrations Of the torpedo
he invented, which has a brain able to
distinguish friends from foes. This tor
pedo with ears that can hear as well as
any persons and with a brain with
single thought-that of distinctions this
mans latest contribution to the nations
defence.
To almost everyone in the audiences
the most wonderful part of the entire Sc
ries of demonstrations of the evening was
when the torpedo. properly balanced,
made use of its ears and brain and turn
ed from one direction to another follow
ing the sound of a rattle held in the hand
of Miss Wood. It was truly marvellous
sight and no person could doubt that the
brain of the torpedo was perfect
