Harriet Beecher Stowe,
A Key to Uncle Tom's Cabin
(1853)
“ My opinion is that American slavery, as I have seen it in the internal slave-trade, as I have seen it on the rice and sugar plantations, and in the city of New Orleans, is full as bad as slavery in any country of the world, heathen or Christian. People who go for visits or pleasure through the Southern States cannot possibly know those things which can be seen of slavery by ship-masters who run up into the back plantations of countries, and who transport the slaves and produce of plantations. ”
