What was the story Mayhew told about a crossing sweep from Dublin?

Orphaned as a child when both parents died of Cholera, he traveled to England for work. He had worked as a bricklayer until he was injured falling off a scaffold at the age of 36. One leg was amputated. He sold matches for five years, earning just 6 pence per day. Finally, he established himself as a crossing sweeper, working the same intersection for more than a decade.
