Western Historical Manuscript Collection: The working title for this story was “The Phantom Submarine.”
Lester Dent, punster is at work here. The name H. O. G. Collins is pretty obvious. Collins is a pig. Nat Piper is head of the vigilantes. The crooked financiers must pay the "piper" for their misdeeds.
Dent also tosses in a little something from Sunday school. “Nat Piper laughed cheerfully and said, "That yoke is the weight of your sins bearing down on you."
See Lamentations, Chapter 1, verse 14, “The yoke of my transgressions is bound by his hand: they are wreathed, and come up upon my neck: he hath made my strength to fall, the LORD hath delivered me into their hands, from whom I am not able to rise up.”
