This is from The Company Man from Herman Melville:
"Not personally. I but happened to hear that he was a passenger. For the rest, though it might be somewhat informal, the gentleman might not object to doing a little business on board. Along the Mississippi, you know, business is not so ceremonious as at the East".
Shouldn't it be "in the East"? When talking about customs I never see people say "at the East". At seems to imply a precise location, a precise point in space, so isn't it a bit weird here?
