The Fairy-Land of Science

*(I
am
quite
aware
of
the
danger
incurred
by
using
this
word
"force",
especially
in
the
plural;
and
how
even
the
most
modest
little
book
may
suffer
at
the
hands
of
scientific
purists
by
employing
it
rashly.
As,
however,
the
better
term
"energy"
would
not
serve
here,
I
hope
I
may
be
forgiven
for
retaining
the
much-
abused
term,
especially
as
I
sin
in
very
good
company.)
Now
the
shower
is
over,
the
sun
comes
out
and
the
ground
is
soon
as
dry
as
though
no
rain
had
fallen.
Tell
me;
what
has
become
of
the
rain-drops?
Part
no
doubt
have
sunk
into
the
ground,
and
as
for
the
rest,
why
you
will
say
the
sun
has
dried
them
up.
Yes,
but
how?
The
sun
is
more
than
ninety-one
millions
of
miles
away;
how
has
he
touched
the
rain-drops?
Have
you
ever
heard
that
invisible
waves
are
travelling
every
second
over
the
space
between
the
sun
and
us?
We
shall
see
in
the
next
lecture
how
these
waves
are
the
sun's
messengers
to
the
earth,
and
how
they
tear
asunder
the
rain-drops
on
the
ground,
scattering
them
in
tiny
particles
too
small
for
us
to
see,
and
bearing
them
away
to
the
clouds.
Here
are
more
invisible
fairies
working
every
moment
around
you,
and
you
cannot
even
look
out
of
the
window
without
seeing
the
work
they
are
doing.
If,
however,
the
day
is
cold
and
frosty,
the
water
does
not
fall
in
a
shower
of
rain;
it
comes
down
in
the
shape
of
noiseless
snow.
Go
out
after
such
a
snow-shower,
on
a
calm
day,
and
look
at
some
of
the
flakes
which
have
fallen;
you
will
see,
if
you
choose
good
specimens,
that
they
are
not
mere
masses
of
frozen
water,
but
that
each
one
is
a
beautiful
six-pointed
crystal
star.
How
have
these
crystals
been
built
up?
What
power
has
been
at
work
arranging
their
delicate
forms?
In
the
fourth
lecture
we
shall
see
that
up
in
the
clouds
another
of
our
invisible
fairies,
which,
for
want
of
a
better
name,
we
call
the
"force
of
crystallization,"
has
caught
hold
of
the
tiny
particles
of
water
before
"cohesion"
had
made
them
into
round
drops,
and
there
silently
but
rapidly,
has
moulded
them
into
those
delicate
crystal
starts
know
as
"snowflakes".
