The Fairy-Land of Science

Then
we
have
what
is
called
a
"glacier,"
or
river
of
ice,
and
this
solid
river
comes
creeping
down
till,
in
Greenland,
it
reaches
the
edge
of
the
sea.
There
it
is
pushed
over
the
brink
of
the
land,
and
large
pieces
snap
off,
and
we
have
"icebergs."
These
icebergs
-
made,
remember,
of
the
same
water
which
was
first
draw
up
from
the
tropics
-
float
on
the
wide
sea,
and
melting
in
its
warm
currents,
topple
over
and
over*
(A
floating
iceberg
must
have
about
eight
times
as
much
ice
under
the
water
as
it
has
above,
and
therefore,
when
the
lower
part
melts
in
a
warm
current,
the
iceberg
loses
its
balance
and
tilts
over,
so
as
to
rearrange
itself
round
the
centre
of
gravity.)
till
they
disappear
and
mix
with
the
water,
to
be
carried
back
again
to
the
warm
ocean
from
which
they
first
started.
In
Switzerland
the
glaciers
cannot
reach
the
sea,
but
they
move
down
into
the
valleys
till
they
come
to
a
warmer
region,
and
there
the
end
of
the
glacier
melts,
and
flows
away
in
a
stream.
The
Rhone
and
many
other
rivers
are
fed
by
the
glaciers
of
the
Alps;
and
as
these
rivers
flow
into
the
sea,
our
drop
of
water
again
finds
its
way
back
to
its
home.
But
when
it
joins
itself
in
this
way
to
its
companions,
from
whom
it
was
parted
for
a
time,
does
it
come
back
clear
and
transparent
as
it
left
them?
From
the
iceberg
it
does
indeed
return
pure
and
clear;
for
the
fairy
Crystallization
will
have
no
impurities,
not
even
salt,
in
her
ice-crystals,
and
so
as
they
melt
they
give
back
nothing
but
pure
water
to
the
sea.
Yet
even
icebergs
bring
down
earth
and
stones
frozen
into
the
bottom
of
the
ice,
and
so
they
feed
the
sea
with
mud.
