One might imagine, that the children of such connections, would fare better, in the hands of their masters, than other slaves. The rule is quite the other way; and a very little reflection will satisfy the reader that such is the case. A man who will enslave his own blood, may not be safely relied on for magnanimity. Men do not love those who remind them of their sins—unless they have a mind to repent—and the mulatto child’s face is a standing accusation against him who is master and father to the child. What is still worse, perhaps, such a child is a constant offense to the wife. She hates its very presence, and when a slaveholding woman hates, she wants not means to give that hate telling effect. Women—white women, I mean—are idols at the south, not wives, for the slave women are preferred in many instances; and if these idols but nod, or lift a finger, woe to the poor victim: kicks, cuffs and stripes are sure to follow. Masters are frequently compelled to sell this class of their slaves, out of deference to the feelings of their white wives; and shocking and scandalous as it may seem for a man to sell his own blood to the traffickers in human flesh, it is often an act of humanity toward the slave-child to be thus removed from his merciless tormentors.
