Questions below refer to the following poem:

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 Ribs
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 —
