The Hatter shook his head mournfully. 'Not I!' he replied. 'We quarrelled last March--just before he went mad, you know--' (pointing with his tea spoon at the March Hare,) '--it was at the great concert given by the Queen of Hearts, and I had to sing "Twinkle, twinkle, little bat! How I wonder what you're at!" You know the song, perhaps?' 'I've heard something like it,' said Alice. 'It goes on, you know,' the Hatter continued, 'in this way:-- "Up above the world you fly, Like a tea-tray in the sky. Twinkle, twinkle--"' Here the Dormouse shook itself, and began singing in its sleep 'Twinkle, twinkle, twinkle, twinkle--' and went on so long that they had to pinch it to make it stop.
