The song of the elves

'Hmmm! it smells like elves!' thought Bilbo, and he looked up at the stars. They were burning bright and blue. Just then there came a burst of song like laughter in the trees:

O! What are you doing,
And where are you going?
Your ponies need shoeing!
The river is flowing!
O! tra-la-la-lally
here down in the valley!

O! What are you seeking,
And where are you making?
The faggots are reeking,
The bannocks are baking!
O! tril-lil-lil-lolly
the valley is jolly,
ha! ha!

O! Where are you going
With beards all a-wagging?
No knowing, no knowing
What brings Mister Baggins,
And Balin and Dwalin
down into the valley
in June
ha! ha!

O! Will you be staying,
Or will you be flying
Your ponies are straying!
The daylight is dying!
To fly would be folly,
To stay would be jolly
And listen and hark
Till the end of the dark
to our tune
ha! ha!

So they laughed and sang in the trees; and pretty fair nonsense I daresay you think it. Not that they would care; they would only laugh all the more if you told them so. They were elves of course…
