+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.

+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.
