Astounding Stories of Super-Science, August 1930

A
common
horror
shook
the
two.
It
did
not
seem
to
affect
the
green
men
in
the
room,
though,
who
advanced
to
the
mechanism
one
by
one
with
a
reluctant
air
as
of
cows
unwilling
to
be
milked.
Each
was
attached
to
the
mechanism
by
the
sucking
disk
on
his
arm,
and
out
of
each
the
blood
poured
through
the
tube.
The
metal
disk
was
replaced
on
his
arm
then
and
he
went
back
to
the
others.
Norman
saw
that
the
frog-men
took
only
from
each
an
amount
of
blood
that
they
could
lose
and
yet
live,
since,
though
each
came
back
pale
and
weak
from
the
mechanism,
they
were
able
to
walk.
"It
must
be
their
food--human
blood!"
Norman
repeated.
"They
may
have
thousands
on
thousands
of
humans
penned
up
like
this,
like
so
many
herds
of
cows,
and
perhaps
they
live
entirely
on
the
life-blood
they
milk
from
them.
Human
cows--God!"
"Norman--look--they're
calling
to
us!"
The
two
stiffened.
All
the
others
in
the
room
had
taken
their
turn
at
the
blood-sucking
mechanism
and
now
the
frog-men
croaked
their
order
to
the
two
fliers.
They
had
forgotten
their
own
predicament
in
the
horror
of
the
scene,
but
now
it
became
real
to
them.
They
backed
against
the
room's
wall,
quivering,
dangerous.
The
frog-guards
came
forward
to
drag
them
to
the
machine.
A
webbed
paw
was
outstretched
but
Hackett
with
a
wild
blow
drove
the
frog-man
back
and
downward.
The
frog-guards
leaped,
and
Norman
and
Hackett
struck
them
back
with
all
the
greater
strength
the
lesser
gravitation
gave
them.
The
room
was
in
an
uproar,
the
green
men
shouting
hoarsely
and
seeming
on
the
point
of
rushing
to
their
aid.
