To the true-hearted, magnanimous citizens ready to place Freedom above Party, and their Country above Politicians, I appeal. [_Immense cheering._] Let them leave old parties, and blend in an organization which, without compromise, will maintain the good cause surely to the end. Here in Massachusetts a large majority concur in sentiment on Slavery,--a large majority desire the overthrow of the Slave Power. These must not scatter their votes, but unite in one firm, consistent phalanx [_applause_], whose triumph will constitute an epoch of Freedom, not only in this Commonwealth, but throughout the land. Such an organization is presented by this Republican Convention, which announces its purpose to coöperate with the friends of Freedom in other States. [_Cheers._] As REPUBLICANS, we go forth to encounter the _Oligarchs_ of Slavery. [_Great applause._] Through this organization we shall secure the election of men who, unseduced and unterrified, will at Washington uphold the principles of Freedom,--and also here at home, in our own community, by example, influence, and vote, will help invigorate Massachusetts. I might go further, and say that by no other organization can we reasonably hope to obtain such men, unless in rare and exceptional cases. Men are but instruments. It will not be enough to choose those who are loyal. Other things must be done here at home. In the first place, all existing laws for the protection of human freedom must be rigorously enforced [_applause, and cries of "Good!"_]; and since these are found inadequate, there must be new laws for this purpose within the limits of the Constitution. Massachusetts will do well in following Vermont, which by special law places the fugitive slave under the safeguard of Trial by Jury and the writ of _Habeas Corpus_. But a Legislature true to Freedom will not fail in remedies. [_Applause._] A simple prohibition, declaring that no person, holding the commission of Massachusetts as Justice of the Peace, or other magistrate, shall assume to act as a Slave-Hunting Commissioner, or as counsel of any Slave-Hunter, under some proper penalty, would go far to render the existing Slave Act inoperative. [_Applause._] There are not many so fond of this base trade as to continue in it, when the Commonwealth sets upon it a legislative brand.
