Its tooth knocks out the "tooth of time." Its hair never turns white with age, nor does it limp with decrepitude.

It is distinguished for its longevity.
THE LENGTH OF ITS LEGS.
It keeps up with the express train, and is present at the opening and the shutting of the mailbags.

It takes a morning run from New York to San Francisco or over to London before breakfast.

It can go a thousand miles at a jump.

It would despise seven-league boots as tedious.
