Hunting and trapping for sure, probably also lumbering, fishing and mining. My grandfather’s grandfather worked in these areas in those years, as a lumberjack. He left his farm and family behind on the Norwegian coast and crossed the Atlantic to find some paid work in that “bloody snowing hell”.
Nevertheless he did exactly that to Pauline’s husband. He also got a provision from her husband’s killing. Later he tried to rape Pauline. That was not in his competence either. But this judge did, because he was corrupt through and through, a former bounty killer himself.
Most of the territories were far from civilization. It didn't mean that the territory's law enforcement system didn't extend throughout the territory. Snow Hill had a sheriff and a Justice of the peace, so it was obviously a county center.
Pollicut, besides being the Justice of peace and a storeowner, also was the banker of Snow Hill.
Wells Fargo had a route through Snow Hill. They transported money. Actually we see the coach on its way to, arriving in an leaving Snow Hill without being robbed.
Well, that is what is going on in the film.
True. But as the outlaw's leader put it “if we fought for our rights, they’d raise the price for our heads and we would be massacred." And as I said before, there was an amnesty coming up.
Too late for what? Let me recapitulate the whole sequence for you.
A young outlaw decides to turn himself in and take his chances with the law. We learn that he is adviced to put his trust in the law by his mother. She is contacted by two bounty killers pretending to be lawyers, who advices her to tell her son to turn himself in, promising to help him to get a fair trial. Instead they shoot him on sight. Silence arrives in Snow Hill in the moment she has just buried her son. The woman knows who Silence is and what he does, and begs him to go after her son’s killer in return for her son’s horse. (No, she is not begging in front of the saloon! There are more buildings than the saloon in Snow Hill!) The bounty killer is still in the saloon eating and drinking. Silence goes there and kills him right on time.
