"He'd dug a hole for a new privy for her, planted her cabbage seeds, weeded and watered her fast-growing corn, curried her mule, fed her hens, hunted herbs in the forest with her and then ground them into powder, helped her make lye soap, boiled quilts outside in a big iron pot over a fire, washed yarb bottles - he'd done everything she required of him and never once talked back." Chapter 12, Page 128
