These can be found in Chapter (or Stave) five. Firstly, consider the action in which Scrooge purchases the prize turkey and sends it to his employee, Bob Cratchit. This is an extremely generous gesture on Scrooge's behalf and one which is unimaginable before Scrooge's transformation. In the first stave, for example, Scrooge was happy to let Bob freeze in his office, and was reluctant to let Bob take Christmas Day as a holiday. Sending him this gift, then, represents the thawing of Scrooge's icy heart.
Secondly, we see another important development in Scrooge's decision to spend Christmas Day with his nephew, Fred. The Scrooge in Stave One would never have entertained such an idea. In fact, he says to Fred:
"Nephew!'' returned the uncle, sternly, "keep Christmas in your own way, and let me keep it in mine!"
Scrooge's change of heart, then, is evidence of how his character has been transformed by the three spirits.
Finally, in the fifth stave, Scrooge also makes a charitable donation to a collection for the city's paupers. But, if we remember what happened in Stave One, Scrooge turned the gentlemen away and implied that it would be better if poor people died:
"If they would rather die,'' said Scrooge, "they had better do it, and decrease the surplus population."
This action provides further evidence of Scrooge's transformation. Gone is the wealthy miser who resented the poor and, in his place, is a man who cares for others and seeks to share his wealth.
