How does Zeena treat Mattie?

Zeena treats the girl somewhat like a slave. Mattie came to the household to help Zeena out during her illness, but Zeena never even thought to pay her for her help.

Mattie Silver came from Stamford, and when she entered the Fromes' household to act as her cousin Zeena's aid it was thought best, as she came without pay, not to let her feel too sharp a contrast between the life she had left and the isolation of a Starkfield farm.

After Mattie had been with Zeena awhile, Zeena began to complain about her work.

His wife had never shown any jealousy of Mattie, but of late she had grumbled increasingly over the house-work and found oblique ways of attracting attention to the girl's inefficiency. Zeena had always been what Starkfield called "sickly," and Frome had to admit that, if she were as ailing as she believed, she needed the help of a stronger arm than the one which lay so lightly in his during the night walks to the farm. Mattie had no natural turn for housekeeping, and her training had done nothing to remedy the defect. She was quick to learn, but forgetful and dreamy, and not disposed to take the matter seriously.

After Mattie and Ethan forge a relationship through their walks home, Zeena seems to get a bit jealous of the girl and talks of hiring someone else when Mattie leaves.

"The doctor don't want I should be left without anybody to do for me," she said in her flat whine.

He had supposed her to be asleep, and the sound of her voice had startled him, though she was given to abrupt explosions of speech after long intervals of secretive silence.

He turned and looked at her where she lay indistinctly outlined under the dark calico quilt, her high-boned face taking a grayish tinge from the whiteness of the pillow.

"Nobody to do for you?" he repeated.

"If you say you can't afford a hired girl when Mattie goes."

Frome turned away again, and taking up his razor stooped to catch the reflection of his stretched cheek in the blotched looking-glass above the wash-stand.

"Why on earth should Mattie go?"

"Well, when she gets married, I mean," his wife's drawl came from behind him.

"Oh, she'd never leave us as long as you needed her," he returned, scraping hard at his chin.

"I wouldn't ever have it said that I stood in the way of a poor girl like Mattie marrying a smart fellow like Denis Eady,"
