I call upon you, then, to receive the petition, and hearken to its prayer. All other petitions asking for change in existing legislation are treated with respect, promptly referred and acted upon. This should not be an exception. The petition asks simply the repeal of an obnoxious statute, which is entirely within the competency of Congress. It proceeds from a large number of respectable citizens, whose autograph signatures are attached. It is brief and respectful, and, in its very brevity, shows that spirit of freedom which should awaken a generous response. In refusing to receive it or refer it, according to the usage of the Senate, or in treating it with any indignity, you offer an affront not only to these numerous petitioners, but also to the great Right of Petition, which is never more sacred than when exercised in behalf of Freedom against an odious enactment. Permit me to add, that by this course you provoke the very spirit which you would repress. There is a plant which is said to grow when trodden upon. It remains to be seen if the Boston petitioners have not something of this quality. But this I know, Sir,--that the Slave Act, like Vice, is "a monster of so frightful mien, As, to be hated, needs but to be seen." And the occurrences of this day will make it visible to the people in new forms of injustice. REPLY TO ASSAILANTS: OATH TO SUPPORT THE CONSTITUTION; WEAKNESS OF THE SOUTH FROM SLAVERY. SECOND SPEECH IN THE SENATE ON THE BOSTON PETITION FOR THE REPEAL OF THE FUGITIVE SLAVE ACT, JUNE 28, 1854. The preceding speech was followed by a debate without example in anger, excitement, and brutality. Mr. Butler, of South Carolina, Mr. Mason, of Virginia, Mr. Pettit, of Indiana, Mr. Dixon, of Kentucky, Mr. Mallory, of Florida, and Mr. Clay, of Alabama, vied with each other in bullying denunciation of Mr. Sumner.
