Thanks Cacian.
But heavens no, it's pure gibberish! Or to be more precise, it's an anagram of a poem by the great New England poet Robert Frost. An anagram is a kind of wordplay hat rearranges the letters of something (in this case, the individual lines) to form new words. This is a fun kind of puzzle, but hard because you have to use all the letters.
Here is Frost's original poem (more or less about innocence). I was a beast to mutilate something so beautiful.
Nothing Gold Can Stay
by Robert Frost
Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
And here's my "improvement" again:
Sit, Nonchalant Doggy!
by Robert Frost (Footrest, brr!)
Refrigerated gnus' tonsils,
Adhere, thou threshold!
Holy seafarer, farewell!
Ah, loony burnouts!
Unabashed, effete, ill sots!
Finks! Renegades, too
(Nowadays dowsed), go not!
Sit, nonchalant doggy!
