yeah height contrast was my first guess (along with location contrast: fog in various different places).
that would be unsurprising. wealthy ppl living up on a hill is a common concept.
sounds right. “yards” is used for stuff besides house yards in modern contexts, e.g. train yards or storage yards.
I’m doubtful about this. I think you did well when looking things up and figuring out what the terms meant. But I think being cold is just normal, not a punishment; I thought the boy was too poor to afford shoes and that’s why his toes were cold.
Being wrathful is normal (then, less so now but still some) for people in authority like the skipper and doesn’t suggest to me that he’s punishing the boy right now. I assume they are out in the cold to do productive work. I’m not sure what kind of punishments were normal then besides I think whipping or various forms of beatings were way more common. The idea of making someone endure cold as a punishment sounds kind of modern to me like something that might be a challenge on a TV show; I think it might make more sense to us now in a world where we have a lot more ability to stay warm. Back then when people were frequently involuntarily cold I’m not sure they’d use cold as a punishment much but I’m no historian just guessing.
