Who asked Scrooge for a charitable contribution?

After Scrooge had reached been thoroughly annoyed by his nephew's cheerful attitude and Christmas spirit, he was visited by two "portly gentlemen."  They were in his office to ask for charitable donations for the poor.  The two men explained that during this festive time of year, it was important to remember the poor with generosity.  They told Scrooge that the poor were in great need.  Scrooge asked the men if there were still prisons for the poor criminals to stay in.  One of the men said that yes, there were.  Scrooge asked if there were still work houses.  One man said that he wished there were not any.  They continued their conversation, asking Scrooge how much money he wanted to donate to the poor.  Scrooge told them that he did not want to give any money to the poor.  He told them that if poor people died that they would "decrease the surplus population."  The men then left.
