Hammond is singling out for special treatment two African-American women he owns as slaves: Sally Johnson and her daughter Louisa. He is also singling out for special status "all the children of both." (Note that Hammond acknowledges the women’s surname, which of course had no legal standing in white society but here seems to allow them an identity Hammond did not give to other of his slaves.) Hammond is admitting to having had possibly three offspring with Sally and Louisa. He also implies (though this is not crystal clear) that if he is not the father, then his white son Harry is: "her children...are both of your blood if not of mine...") He is troubled by and in some way deeply cares about what happens not only to his possible children but also to Louisa and Sally. He does not want them to pass out of Hammond family control, and he has made a will to be sure his desires are carried out. But here he is taking the added precaution of instructing his son on what to do to make sure the women and children do not leave the Hammond "family." Hammond is blunt, and that’s important—his candor offers a window on the mentality of a sexual predator and exploiter of his slaves. At the same time, he’s a solid citizen who rose to the top of white political and economic society in South Carolina.
