SCROOGE
'Now, I'll tell you what, my friend,' said Scrooge. 'I am not going to stand this sort of thing any longer. And therefore,' he continued, leaping from his stool, and giving Bob such a dig in the waistcoat that he staggered back into the tank again--'and therefore I am about to raise your salary!' ... 'A merry Christmas, Bob!' said Scrooge, with an earnestness that could not be mistaken, as he clapped him on the back. 'A merrier Christmas, Bob, my good fellow, than I have given you for many a year! I'll raise your salary, and endeavour to assist your struggling family, and we will discuss your affairs this very afternoon, over a Christmas bowl of smoking bishop, Bob! Make up the fires and buy another coal-scuttle before you dot another i, Bob Cratchit!'
