The Fairy-Land of Science
·

The
reason
of
this
is
that
grasses,
sedges,
rushes,
nut-trees,
willow,
and
the
others
we
have
mentioned,
have
all
of
them
a
great
deal
of
pollen-dust,
and
as
the
wind
blows
them
to
and
fro,
it
wafts
the
dust
from
one
flower
to
another,
and
so
these
plants
do
not
want
the
insects,
and
it
is
not
worth
their
while
to
give
out
honey,
or
to
have
gaudy
or
sweet-scented
flowers
to
attract
them.
But
wherever
you
see
bright
or
conspicuous
flowers
you
may
be
quite
sure
that
the
plants
want
the
bees
or
some
other
winged
insect
to
come
and
carry
their
pollen
for
them.
Snowdrops
hanging
their
white
heads
among
their
green
leaves,
crocuses
with
their
violet
and
yellow
flowers,
the
gaudy
poppy,
the
large-
flowered
hollyhock
or
the
sunflower,
the
flaunting
dandelion,
the
pretty
pink
willow-herb,
the
clustered
blossoms
of
the
mustard
and
turnip
flowers,
the
bright
blue
forget-me-not
and
the
delicate
little
yellow
trefoil,
all
these
are
visited
by
insects,
which
easily
catch
sight
of
them
as
they
pass
by
and
hasten
to
sip
their
honey.
Sir
John
Lubbock
has
shown
that
bees
are
not
only
attracted
by
bright
colours,
but
that
they
even
know
one
colour
from
another.
He
put
some
honey
on
slips
of
glass
with
coloured
papers
under
them,
and
when
he
had
accustomed
the
bees
to
find
the
honey
always
on
the
blue
glass,
he
washed
this
glass
clean,
and
put
the
honey
on
the
red
glass
instead.
Now
if
the
bees
had
followed
only
the
smell
of
the
honey,
they
would
have
flown
to
the
red
glass,
but
they
did
not.
They
went
first
to
the
blue
glass,
expecting
to
find
the
honey
on
the
usual
colour,
and
it
was
only
when
they
were
disappointed
that
they
went
off
to
the
red.
