I've read Baxter's and Pratchett's work The Long Earth and am looking forward to reading the rest of the series, but am taking a quick break to read Timothy Zahn's Thrawn.
The colonial party that the narrative intermittently follows picks up the blacksmith (whose name escapes me for the moment) and his payment seems to shock the party members. I don't know if I skipped over it or if it was too subtle for me to realize, but what was his payment? If there is an answer but it's in the later books, please answer with a simple "yes", that would be lovely. No spoilers, please!
