William O. Blake, The History of Slavery and the Slave Trade (1861)
“ Crews have been known to die by the fruit of their own crime, and leave ships almost helpless. They have carried the scourge with them. The coast fever of Africa, bad enough where it has its birth, came in these vessels, and has assumed perhaps a permanent abode in the western regions of the world. No fairer sky or healthier climate were there on earth, than in the beautiful bay, and amid the grand and picturesque scenery of Rio de Janeiro, in Brazil. But it became a haunt of slavers, and the dead of Africa floated on the glittering waters, and were tumbled upon the sands of its harbor. ”
