+  There were doors all round the hall, but they were all locked; and when
+  Alice had been all the way down one side and up the other, trying every
+  door, she walked sadly down the middle, wondering how she was ever to
+  get out again.
+
+  Suddenly she came upon a little three-legged table, all made of solid
+  glass; there was nothing on it except a tiny golden key, and Alice's
+  first thought was that it might belong to one of the doors of the hall;
+  but, alas! either the locks were too large, or the key was too small,
+  but at any rate it would not open any of them. However, on the second
+  time round, she came upon a low curtain she had not noticed before, and
+  behind it was a little door about fifteen inches high: she tried the
+  little golden key in the lock, and to her great delight it fitted!
