Quote #4
We put in a little iron pump, one of the first turned out by my works near the capital. (23.4)
This passage starts a lengthy description of the technological means used to restore the holy fountain. Twain wants the readers to understand what he's doing, even if Hank keeps the Arthurians in the dark.
Quote #5
"If the king does not arrive, I will have myself ridden on a rail: if he does I will ride you on a rail instead." (24.13)
Hank is confronting the phony magician here. He's using technology to cheat, since he used the telegraph to figure out where the king was, but he's also using technology to set the terms of the competition. The loser will literally be ridden out of the valley on a rail… you know, the train kind.
