A rather scarce address delivered in the House of Representatives by Virginia slave-holder, mouthpiece for the pro-slavery Southern coalition, and later Speaker of the Confederate State House of Representatives, Thomas Bocock [1815-1891]. 

I suppose all we need to know about him and about the acidic speech is that when Democratic senator Preston Brooks of South Carolina began repeatedly beating Charles Sumner with a metal cane in the House because of his speech against slavery, Bocock cheered him on and afterward praised him for his actions. 

Bocock, Thomas S. Slavery in the Territories. Speech of Hon. Thomas S. Bocock, of Virginia. In the House of Representatives, June 30, 1848. In Committee of the Whole on the State of the Union, on the Civil and Diplomatic Appropriation Bill. 1848. 8pp.

A good + copy in wraps, essentially disbound. Text good with light foxing.
