Fog on the Barrow-Downs(Extract from the book by J. R. R. Tolkien "The Lord of the Rings". Abridged)That night they heard no noises. But either in his dreams or out of them, he could not tell which, Frodo heard a sweet singing run­ning in his mind;1 a song that seemed to come like a pale light be-hind a grey rain-curtain.The vision melted into waking;2 and there was Tom whistling; and the sun was already slanting down the hill and through the open window.
