<p>The organs of smell in a Vulture
and a Carrion Crow are so keen that
they can scent their food for a distance
of forty miles, so they say.</p>
<p>The wings of birds are not only to
aid locomotion in the air, but also on
the ground and water. One bird even
has claws in the "elbows" of its
wings to aid in climbing.</p>
<p>The Elephant does not smell with
his trunk. His olfactory nerves are
contained in a single nostril, which is
in the roof of the mouth, near the
front.</p>
<p>Humming Birds are domesticated
by placing in their cages a number of
paper flowers of tubular form, containing
a small quantity of sugar and
water, which must be frequently
renewed. Of this liquid the birds
partake and quickly become apparently
contented with their captivity.</p>
<p>Rightly considered, a Spider's web
is a most curious as well as a most
beautiful thing. When we were children,
the majority of us supposed that
the Spider's web was pulled out of its
mouth, and that the little insect had a
large reel of the stuff in his stomach,
and that he could almost instantly add
feet, yards, or rods to the roll. The
facts are that Spiders have a regular
spinning machine—a set of tiny tubes
at the far end of the body—and that
the threads are nothing more nor less
than a white, sticky fluid, which
hardens as soon as it comes in contact
with the air. The Spider does not
really and truly "spin," but begins a
thread by pressing his "spinneret"
against some object, to which the
liquid sticks. He then moves away
and by constantly ejecting the fluid
and allowing it to harden, forms his
ropes or wonderful geometrical nets.</p>
<p>Birds have separate notes of warning
to indicate whether danger is in
the shape of a Hawk or a Cat or a
man. If a Cat, a Hawk, or an Owl is on
the move, the Birds, especially Blackbirds,
always utter a clattering note,
constantly repeated, and Chickens
have a special sound to indicate the
presence of a Hawk. But when disturbed
by man the Blackbirds have
quite a different sound of alarm and
the Chickens also.</p>
