The Fairy-Land of Science

First
we
must
learn
something
about
the
sun
itself,
since
it
is
the
starting-place
of
all
the
sunbeams.
If
the
sun
were
a
dark
mass
instead
of
a
fiery
one
we
should
have
none
of
these
bright
cheering
messengers,
and
though
we
were
turned
face
to
face
with
him
every
day
we
should
remain
in
one
cold
eternal
night.
Now
you
will
remember
we
mentioned
in
the
last
lecture
that
it
is
heat
which
shakes
apart
the
little
atoms
of
water
and
makes
them
gloat
up
in
the
air
to
fall
again
as
rain;
and
that
if
the
day
is
cold
they
fall
as
snow,
and
all
the
water
is
turned
into
ice.
But
if
the
sun
were
altogether
dark,
think
how
bitterly
cold
it
would
be;
far
colder
than
the
most
wintry
weather
ever
known,
because
in
the
bitterest
night
some
warmth
comes
out
of
the
earth,
where
it
has
been
stored
from
the
sunlight
which
fell
during
the
day.
But
if
we
never
received
any
warmth
at
all,
no
water
would
ever
rise
up
into
the
sky,
no
rain
ever
fall,
no
rivers
flow,
and
consequently
no
plants
could
grow
and
no
animals
live.
All
water
would
be
in
the
form
of
snow
and
ice,
and
the
earth
would
be
one
great
frozen
mass
with
nothing
moving
upon
it.
So
you
see
it
becomes
very
interesting
for
us
to
learn
what
the
sun
is,
and
how
he
sends
us
his
beams.
How
far
away
from
us
do
you
think
he
is?
On
a
fine
summer's
day
when
we
can
see
him
clearly,
it
looks
as
if
we
had
only
to
get
into
a
balloon
and
reach
him
as
he
sits
in
the
sky,
and
yet
we
know
roughly
that
he
is
more
than
ninety-one
millions
of
miles
distant
from
our
earth.
