Henry Koster, Travels in Brazil
“ African who has become chearful, and seems to have forgotten his former state, is a more valuable slave than a creole negro or mulatto. He will be generally more fit to be trusted. Far from the latter submitting quietly to the situation in which they have been born, they bear the yoke of slavery with impatience; the daily sight of so many individuals of their own casts, who are in a state of freedom, makes them wish to be raised to an equality with them, and they feel at every moment their unfortunate doom. ”
