“The boat took on board, at Hannibal, a drove of slaves, bound for the New Orleans market. They numbered from fixty to sixty, consisting of men and women from eighteen to forty years of age. A drove of slaves on a southern steamboat, bound for the cotton or sugar regions, is an occurrence so common, that no one, not even the passengers, appear to notice it, though they clank their chains at every step.”
William Wells Brown, from Narrative of William W. Brown, a Fugitive Slave, 1847
