There were twenty-nine hundred petitioners, among whom were many who had heretofore sustained this atrocious measure; but they felt at last relieved from this service. In this respect this petition marks an epoch in public sentiment.

Its reception in the Senate marks an epoch there. It was presented on the 22d of June, by Mr. Rockwell, the new Senator in Mr. Everett's place, who moved its reference to the Committee on the Judiciary. Other petitions of like character had been treated very unceremoniously. This was debated at length, and finally referred according to the motion of Mr. Rockwell.

On the 26th of June the debate began, in which Mr. Jones, of Tennessee, Mr. Rockwell, of Massachusetts, then again Mr. Jones, and Mr. Brodhead, of Pennsylvania, took part. At this stage Mr. Sumner spoke as follows.

Mr. President,—I begin by answering the interrogatory propounded by the Senator from Tennessee [Mr. Jones]: "Can any one suppose, that, if the Fugitive Slave Act be repealed, this Union can exist?" To which I reply at once, that, if the Union be in any way dependent on an act—I cannot call it a law—so revolting in every aspect as that to which he refers, then it ought not to exist. To much else that has fallen from that Senator I do not desire to reply. Matters already handled again and again, in the long-drawn-out debates of this session, he has discussed at length. Like the excited hero of Macedonia, he has renewed past conflicts,—

"And thrice he routed all his foes, and thrice he slew the slain."

Of what the Senator said on the relations of Senators, North and South, of a particular party, it is not my province to speak. And yet I do not turn from it without expressing at least some confidence that men from the North, whether Whigs or Democrats, will neither be cajoled by any temptation nor driven by any lash from the support of those principles which are inseparable from the true honor and welfare of the country. At last there will be, I trust, a backbone in the North.

My colleague has already remarked that this petition proceeds from persons many of whom were open supporters of the alleged Compromises of 1850, including even the odious Fugitive Slave Act. I have looked over the long list, and, so far as I can judge, find this to be true. And, in my opinion, the change shown by these men is typical of the change in the community of which they constitute a prominent part. Once the positive upholders of the Fugitive Slave Act, they now demand its unconditional repeal.

There is another circumstance worthy of especial remark. This petition proceeds mainly from persons connected with trade and commerce. Now it is a fact too well known in the history of England, and of our own country, that these persons, while often justly distinguished by individual charities, have been lukewarm in opposition to Slavery. Twice in English history did "the mercantile interest" frown upon endeavors to suppress the atrocity of Algerine Slavery; steadfastly in England it sought to baffle Wilberforce's great effort for the abolition of the African slave-trade; and at the formation of our own Constitution, it stipulated a sordid compromise, by which this same detested, Heaven-defying traffic was saved for twenty years from American judgment. But now it is all changed,—at least in Boston. Representatives of "the mercantile interest" place themselves in the front of the new movement against Slavery, and, by their explicit memorial, call for the removal of a grievance which they have bitterly felt in Boston.

Mr. President, this petition is interesting to me, first, as it asks a repeal of the Fugitive Slave Act, and, secondly, as it comes from Massachusetts. That repeal I shall be glad, at any time, now and hereafter, as in times past, to sustain by vote and argument; and I trust never to fail in any just regard for the sentiments or interests of Massachusetts. With these few remarks I would gladly close. But there has been an arraignment, here to-day, both of myself and of the Commonwealth which I represent. To all that has been said of myself or the Commonwealth, so far as it is impeachment of either, so far as it subjects either to any real censure, I plead openly, for myself and for Massachusetts, "Not guilty." But pardon me, if I do not submit to be tried by the Senate, fresh from the injustice of the Nebraska Bill. In the language of the Common Law, I put myself upon "God and the country," and claim the same trial for my honored Commonwealth.
