I like to see it lap the Miles

I like to see it lap the miles,

And lick the valleys up,

And stop to feed itself at tanks;

And then, prodigious, step

 Around a pile of Mountains,

And, supercilious, peer

In shanties by the sides of roads;

And then a quarry pare

 To fit its sides, and crawl between,

Complaining all the while

In horrid, hooting stanza;

Then chase itself down hill

 And neigh like Boanerges;

Then, punctual as a star,

Stop – docile and omnipotent –

At its own stable door.
