Mr. President, before this question passes away, I think I ought to make answer to the Senator from South Carolina,--though perhaps there is no occasion for it. [_“No!” from several Senators._] Only one word. I exposed to-day the _Barbarism of Slavery_. What the Senator has said in reply I may well print as an additional illustration. That is all. Mr. Hammond, of South Carolina, said:-- “I hope he will do it.” * * * * * The first pamphlet edition of this speech contained a note which is preserved here. “The following letter, from a venerable citizen, an ornament of our legislative halls at the beginning of the century, and now the oldest survivor of all who have ever been members of Congress, is too valuable in testimony and counsel to be omitted in this place. “‘BOSTON, June 5, 1860. “‘Dear Sir,--I have read a few abstracts from your noble speech, but must wait for it in a pamphlet form, that I may read it in such type as eyes in the eighty-ninth year of their age will permit. But I have read enough to approve, and rejoice that you have been permitted thus truly, fully, and faithfully to expose the ‘Barbarism’ of Slavery on that very floor on which you were so cruelly and brutally stricken down by the spirit of that Barbarism. “‘I only hope that in an Appendix you will preserve the _vera effigies_ of that insect that attempted to sting you. Remember that the value of amber is increased by the insect it preserves. “‘Yours, very truly, “‘JOSIAH QUINCY.’” APPENDIX. The speech on the Barbarism of Slavery was followed by outbursts of opinion which exhibit the state of the public mind at the time. There was approval and opposition, and there was also menace of violence. As this was promptly encountered, it could never be known to what extent the plot had proceeded.
