Before Alice enters the dream state -and falls to Wonderland - on the bank beside her sister, the reader is told by Carroll that it was a hot day and that Alice thought of the possibility of making a daisy chain:
Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do... 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.
Near the end of the book, however, as Alice exits Wonderland, Carroll presents the reader with what appears to be a different season. As Alice is attacked by the pack of cards, she:
...tried to beat them off, and found herself lying on the bank, with her head in the lap of her sister, who was gently brushing away some dead leaves that had fluttered down from the trees upon her face.
Therefore, while Alice’s Adventures in Wonderland begins in a spring-like setting, the book appears to end in a fall-like one. Do several months elapse between the spring-like beginning and fall-like end of *Wonderland?
