Phase 1

Boy Crossing-Sweepers and Tumblers. (Volume 2): "We goes general to Waterloo-place when the Opera’s on. We sends on one of us ahead, as a looker-out, to look for the policeman, and then we follows. It’s no good tumbling to gentlemen going to the Opera; it’s when they’re coming back they gives us money."

Phase 2

The “King” of the Tumbling-Boy Crossing-Sweepers. (Volume 2)
