It happened that a Dog had got a piece of meat and was carrying
it home in his mouth to eat it in peace. Now on his way home he had
to cross a plank lying across a running brook.
As he crossed, he looked down and saw his own shadow reflected in
the water beneath. Thinking it was another dog with another piece
of meat, he made up his mind to have that also.
So he made a snap at the shadow in the water, but as he opened his
mouth the piece of meat fell out, dropped into the water and was never
seen more.
Beware lest you lose the substance by grasping at the shadow.
