Her first husband developed a hankering for corn whiskey and started using his big hands to make big fists. Ajarry wasn't sad to see him disappear down the road when they sold him to a sugarcane estate in Florida. She next took up with one of the sweet boys from the southern half. Before he passed from cholera he liked to share stories from the Bible, his former master being more liberalminded when it came to slaves and religion. She enjoyed the stories and parables and supposed that white men had a point: Talk of salvation could give an African ideas. Poor sons of Ham. Her last husband had his ears bored for stealing honey. The wounds gave up pus until he wasted away.

Ajarry bore five children by those men, each delivered in the same spot on the planks of the cabin, which she pointed to when they misstepped. That's where you came from and where I'll put you back if you don't listen. Teach them to obey her and maybe they'll obey all the masters to come and they will survive. Two died miserably of fever. One boy cut his foot while playing on a rusted plow, which poisoned his blood. Her youngest never woke up after a boss hit him in the head with a wooden block. One after another. At least they were never sold off, an older woman told Ajarry. Which was true—back then Randall rarely sold the little ones. You knew where and how your children would die. The child that lived past the age of ten was Cora's mother, Mabel.

Ajarry died in the cotton, the bolls bobbing around her like whitecaps on the brute ocean. The last of her village, keeled over in the rows from a knot in her brain, blood pouring from her nose and white froth covering her lips. As if it could have been anywhere else. Liberty was reserved for other people, for the citizens of the City of Pennsylvania bustling a thousand miles to the north. Since the night she was kidnapped she had been appraised and reappraised, each day waking upon the pan of a new scale. Know your value and you know your place in the order. To escape the boundary of the plantation was to escape the fundamental principles of your existence: impossible. It was her grandmother talking that Sunday evening when Caesar approached Cora about the underground railroad, and she said no. Three weeks later she said yes.

This time it was her mother talking.
