The analyses of a text #1

This novel is set in a Chinese village before World War One.
Here "she" refers to the newly-wedded wife of the protagonist Wang Lung's, she was a maid to a very rich family.

But she never talked, this woman, except for the brief necessities of life. Wang Lung, watching her move steadily and slowly about the rooms on her big feet, watching secretly the stolid, square face, the unexpressed, half-fearful look of her eyes, made nothing of her. At night he knew the soft firmness of her body. But in the day her clothes, her plain blue cotton coat and trousers, covered all that he knew, and she was like a faithful, speechless serving maid, who is only a serving maid and nothing more. And it was not meet that he should say to her, "Why do you not speak?" It should be enough that she fulfilled her duty.

1. I'd like to know what "made nothing of her" means.
2. I think it refers to the "that" clause.
If so, I'd like to know the implied object of "meet."
Thank you in advance for your help.
