How does the author use foreshadowing in The Deerslayer?

In Chapter Two, the Hutter home, otherwise referred to as the castle, provides foreshadowing about the two Hutter daughters. One side of the bedroom, presumably Hetty's side, is simple and plain. The other side, presumably Judith's, has expensive materials and several items for personal decoration, such as ribbons and caps. This room is meant to represent the different characters of the girls and give Deerslayer, as well as the reader, a sense of what to expect of the girls when he meets them.
