Analysis of The Horse

A sparrow hopped about the street,
  And he was not a bit afraid;
He flew between a horse's feet,
  And ate his supper undismayed:
I think myself the horse knew well
  The bird came for the grains that fell.

For his eye was looking down,
  And he danced the corn about
In his nose-bag, till the brown
  Grains of corn were tumbled out;
And I fancy that he said,
  'Eat it up, young Speckle-Head!'

The driver then came back again,
  He climbed into the heavy dray;
And he tightened up the rein,
  Cracked his whip and drove away.
But when the horse's ribs were hit,
  The sparrow did not care a bit.
