The Wild Boar and the Fox 


  A WILD BOAR stood under a tree and rubbed his tusks against the
trunk.  A Fox passing by asked him why he thus sharpened his
teeth when there was no danger threatening from either huntsman
or hound.  He replied, "I do it advisedly; for it would never do
to have to sharpen my weapons just at the time I ought to be
using them."
