 Alice was beginning to get very tired of sitting by her sister on the bank,
 and of having nothing to do: once or twice she had peeped into the book
 her sister was reading, but it had no pictures or conversations in it,
 `and what is the use of a book,' thought Alice `without pictures or
 conversation?'
 So she was considering in her own mind (as well as she could, for the
 hot day made her feel very sleepy and stupid), whether the pleasure of
 making a daisy-chain would be worth the trouble of getting up and
 picking the daisies, when suddenly a White Rabbit with pink In another
 moment down went Alice after it, never once considering how in the world
 she was to get out again.
 The rabbit-hole went straight on like a tunnel for some way, and then
 dipped suddenly down, so suddenly that Alice had not a moment to think
 about stopping herself before she found herself falling down a very deep
 well.
 Either the well was very deep, or she fell very slowly, for she had
 plenty of time as she went down to look about her and to wonder what was
  going to happen next. First, she tried to look down and make out what
 she was coming to, but it was too dark to see anything; then she looked
 at the sides of the well, and noticed that they were filled with
 cupboards and book-shelves; here and there she saw maps and pictures
 hung upon pegs. She took down a jar from one of the shelves as she
 passed; it was labelled `ORANGE MARMALADE', but to her great
 disappointment it was empty: she did not like to drop the jar for fear
 of killing somebody, so managed to put it into one of the cupboards as
 she fell past it.
