Astounding Stories of Super-Science, August 1930

Pushing
the
protrudent
round
button
on
his
mysterious
bracelet
as
he
spoke,
he
leaned
over
the
edge
of
the
trap-door
and
awaited
results.
They
were
not
long
in
coming.
The
vibration
he
was
already
under
from
the
invisibility
rays
seemed
to
double.
Alternate
waves
of
giddiness
and
depression,
of
push
and
pull,
swept
over
him.
A
minute
of
it
was
enough.
He
pressed
the
round
button
that
now
protruded,
ending
this
influence,
and
faced
Marjorie,
stating:
"I'm
positive
now
that
these
things
control
descent
and
ascent.
As
nearly
as
I
can
figure,
the
rays
work
on
the
principle
of
an
endless
belt.
If
you're
up
here,
you
get
carried
down,
and
vice
versa.
As
to
how
wide
the
belt
is,
and
whether
you
can
move
sideways
on
it,
remains
to
be
seen.
Anyway,
I'm
going
to
take
a
chance.
I'll
go
first.
If
my
guess
is
wrong,
you--well,
needn't
follow."
"No,
I'm
going
with
you!"
she
declared
resolutely.
"We've
come
this
far
together.
I
shan't
be
left
alone
now.
Let's
go!"
And
again
her
soft,
warm
hand
was
in
his.
Lord,
what
a
girl!
How
many
would
be
brave
enough
to
take
a
gamble
like
that,
on
a
fellow's
mere
supposition?
"All
right--go
it
is!"
he
said.
"Push
your
round
button,
like
this."
He
showed
her
the
way
he
thought
was
right,
pushed
his
own.
"Ready?"
"Ready!"
Their
voices
were
grave.
It
was
a
grim
prospect,
stepping
off
into
space
like
that,
with
only
a
guess
between
them
and
death.
