-- but the girl who could be gratified by a Robert Martin's riding about the country to get walnuts for her, might very well be conquered by Mr. Elton's admiration. (Chapter 4)

I think Mr. Martin riding about the country to get walnuts for Harriet is incredibly sweet. Emma seems to dismiss it as trivial. IMO simple, thoughtful gestures like this are very gratifying—Mr. Martin’s gesture proves he listens to Harriet and is willing to expend time and effort to make her happy. Moonlight walks and having the shepherd's son on purpose to sing for her are also very sweet and much more to the point than the “warm personal praise which she [Emma] had drawn from Mr. Elton” about Harriet in Chapter 4. In Chapter 6, when Mr. Elton offers to take Harriet’s picture into town to be framed Emma thinks "This man is almost too gallant to be in love" but it seems to me Mr. Elton says nothing of Harriet.
