PART

THE
PRINCIPLES,
HAVING
SETTLED
THEIR
DIFFERENCES,
FINISH
THE
JOB
Another
day
had
passed,
and
the
Flight
Folk
had
again
gathered
together
and
were
awaiting
the
arrival
of
Efficiency
who,
as
usual,
was
rather
late
in
making
an
appearance.
The
crowd
was
larger
than
ever,
and
among
the
newcomers
some
of
the
most
important
were
the
three
Stabilities,
named
Directional,
Longitudinal,
and
Lateral,
with
their
assistants,
the
Rudder,
Elevator,
and
Ailerons.
There
was
Centrifugal
Force,
too,
who
would
not
sit
still
and
created
a
most
unfavourable
impression,
and
Keel-Surface,
the
Dihedral
Angle,
and
several
other
lesser
fry.
"Well,"
said
Centrifugal
Force,
"I
wish
this
Efficiency
I've
heard
so
much
about
would
get
a
move
on.
Sitting
still
doesn't
agree
with
me
at
all.
Motion
I
believe
in.
There's
nothing
like
motion--the
more
the
better."
"We
are
entirely
opposed
to
that,"
objected
the
three
Stabilities,
all
in
a
breath.
"Unless
it's
in
a
perfectly
straight
line
or
a
perfect
circle.
Nothing
but
perfectly
straight
lines
or,
upon
occasion,
perfect
circles
satisfy
us,
and
we
are
strongly
suspicious
of
your
tendencies."
"Well,
we
shall
see
what
we
shall
see,"
said
the
Force
darkly.
"But
who
in
the
name
of
blue
sky
is
this?"
And
in
tripped
Efficiency,
in
a
beautifully
"doped"
dress
of
the
latest
fashionable
shade
of
khaki-coloured
fabric,
a
perfectly
stream-lined
bonnet,
and
a
bewitching
little
Morane
parasol,[4]
smiling
as
usual,
and
airily
exclaiming,
"I'm
so
sorry
I'm
late,
but
you
see
the
Designer's
such
a
funny
man.
He
objects
to
skin
friction,[5]
and
insisted
upon
me
changing
my
fabric
for
one
of
a
smoother
surface,
and
that
delayed
me.
Dear
me,
there
are
a
lot
more
of
us
to-day,
aren't
there?
I
think
I
had
better
meet
one
at
a
time."
And
turning
to
Directional
Stability,
she
politely
asked
him
what
he
preferred
to
do.
