Leading "fire eater" William Lowndes Yancey of Alabama addressed a crowd of Democrats at the Cooper Union Institute in an evening speech. Yancey, in what observers described as a mild mannered presentation that belied his reputation, defended the South and slavery and called for the enforcement of the Fugitive Slave Law. He concluded by saying that the preservation of the Union needed a Democratic success in New York in the general election and called for "fusion." (By John Osborne)
