A city slave is almost a freeman, compared with a slave on the plantation. He is much better fed and clothed, and enjoys privileges altogether unknown to the slave on the plantation.

Context

“In learning to read, I owe almost as much to the bitter opposition of my master, as to the kindly aid of my mistress. I acknowledge the benefit of both.
I had resided but a short time in Baltimore before I observed a marked difference, in the treatment of slaves, from that which I had witnessed in the country. A city slave is almost a freeman, compared with a slave on the plantation. He is much better fed and clothed, and enjoys privileges altogether unknown to the 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.” source
