LECTURE
BY SCIENTIST
Rotarians Promise FL Paso-
ans an Interesting Enter
tainment Tonight.

80ntraviIle Wood, scientist and lee
turer. arrived in FL Paso today, for
his appearance for FL Paso Rotary
at the Texas Grand theater tonight
I'm his lecture on demonstration OF
the gyroscope. the torpedo. the ultra
violet rays and other scientific fea-
lures that are attracting the atten-
ton of the world today.
lIr. Wood was secured by Rotary
after The officers had heard much OF
the success OF his lecture I'm the east
Robert Krakauer, president, and F.
3 Fletcher. secretary, Of FL Paso Ro-

The lecturer while treating Of scien-
titic subjects, does SO in most in
larestiug manner. so that the average
person can understand and appreciate
The talk, 10 is stated
This is one OF number OF high
Grade entertainments which Rotary
has arranged for this season, IN an
effort 20 give high class amusements
and educational features 20 the Qeo-
pie Of the city
Torpedo With Ears.
During the years OF research work
which 1 spent in my laboratory ar
BerWyu. ILL.," said Mr.. Wood, Il per
feCred a device for the direction OF
toped0es by sound waves, and this is
way boy which the government can
cope with the submarine AE TOR
pedo has ears The mechanism OF
the torpedo IS directed oy brain
box the secret of which is known
only 20 The high officials Of the navy
department and TO me This brain
box is surrounded by high explosives
So that the secret Of ii may be con-
fined only 20 the proper officers OF
our government
Even ] cannot open the brain
box said Mr.. Wood, after it has
been installed in the torpedo. The
method OF shooting the torpedo is to
place a master brain box in the wa
ter. and thus detect the presence Of
ships by the sound waves created by !
the prOpellers Of the vessels The /
tone OF any particular enemy ship (
may be detected and the brain box
of the torpedo is then artuned TO this
zone It viii then seek out the ship
20 which Il IS toned. and sink it.
Stops When ship Stops.
I'm the event the ship desired as
prey stops its engines" continued AR
Wood. the torpedo takes a dive and
remains deep beneath the surface Of .
the waves until the ship is started
again Then It goes after its mark .
In case the torpedo is thrown out OF
the water by the rolling waves. il viii T
right itself again and seek its prey f
When placed in the water they can be F.
so arranged that the pressure bearing f.
upon certain diapnragms will auto
maticaIly explode the same at given .
pressures- BY this means, after the
depth Of the submarine is located .
these automatic exploding devices can D
be set to explode At the proper depth. 4
u have also a device which is
worked on the sound wave system .
that drops chains OF protection about
the sides of q snip when q torpedo
approaches it.
KaIser Must Quit Soon.
Knowing as 7 do the inside work
inEs OF the naval board and its CO.
operation with scientists and enEi- F.
ueers at large. I feel confident that
if the people respond freely TO the
Liberty loan appeal, there viii be no
doubt that we win have the kaiser
with his hands up inside six months F.
time said Mr. Wood
ar. Wood IS TO give a special dem /
Oustratiou OF one OF the ears used /
ON the torpedo at the lecture this /
evening.
The method OF using q time fuse
for the exploding OF protectiles and I
bombs Is practically thing OF the
past" said AIr. Wood, particularly in 4
connection with explosives when used +
