There are no two spaces on the surface of the globe, equal in extent, (and careful examination will verify what I am about to state,) which present so many distinctive features of resemblance, whether we consider the common regions of latitude in which they lie, the common nature of their boundaries, their common productions, their common climate, or the common Barbarism which sought shelter in both. I do not stop to inquire why Slavery--banished at last from Europe, banished also from that part of this hemisphere which corresponds in latitude to Europe--should have intrenched itself, in both hemispheres, in similar regions of latitude, so that Virginia, Carolina, Mississippi, and Missouri are the American complement to Morocco, Algiers, Tripoli, and Tunis. But there is one important point in the parallel which remains to be fulfilled. The barbarous Emperor of Morocco, in the words of a treaty, so long ago as the last century, declared his desire that “the odious name of Slavery might be effaced from the memory of men”;[53] while Algiers, Tripoli, and Tunis, whose tenacity for the Barbarism was equalled only by that of South Carolina, have renounced it one after another, and delivered it over to the indignation of mankind. Following this example, the parallel will be complete, and our Barbary will become the complement in Freedom to the African Barbary, as it has already been its complement in Slavery, and is unquestionably its complement in geographical character. II. From the consideration of Slavery in its practical results, illustrated by contrast between the Free States and Slave States, I pass to another stage of the argument, where Slavery appears in its influence on the CHARACTER OF SLAVE-MASTERS. Nothing could I undertake more painful, and yet there is nothing more essential to the discussion, especially in response to pretensions of Senators on this floor, nor is there any point on which the evidence is more ample.
