A city slave is almost a freeman, compared with a slave on the plantation. . . . There is a vestige of decency, a sense of shame, that does much to curb and check those outbreaks of atrocious cruelty so commonly enacted upon the plantation. He is a desperate slaveholder, who will shock the humanity of his non-slaveholding neighbors with the cries of his lacerated slave. Few are willing to incur the odium attaching to the reputation of being a cruel master; and above all things, they would not be known as not giving a slave enough to eat.
What inference can be drawn about city slaveholders in this excerpt?
