+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
+conversations?'
+
+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 eyes ran
+close by her.
+
+There was nothing so VERY remarkable in that; nor did Alice think it so
+VERY much out of the way to hear the Rabbit say to itself, 'Oh dear!
+Oh dear! I shall be late!' (when she thought it over afterwards, it
+occurred to her that she ought to have wondered at this, but at the time
+it all seemed quite natural); but when the Rabbit actually TOOK A WATCH
+OUT OF ITS WAISTCOAT-POCKET, and looked at it, and then hurried on,
+Alice started to her feet, for it flashed across her mind that she had
+never before seen a rabbit with either a waistcoat-pocket, or a watch
+to take out of it, and burning with curiosity, she ran across the field
+after it, and fortunately was just in time to see it pop down a large
+rabbit-hole under the hedge.
+
+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.
