Vote, then, so as to vindicate the declared policy of your candidate for the Presidency. Vote so as to vindicate the Declaration of Independence, which is dishonored by being made the authority for a false pretension in the name of Popular Sovereignty. Vote so as to vindicate the early policy of the Fathers, who organized the Prohibition of Slavery in the Territories. Vote so as to vindicate the early policy of Massachusetts, who, in the Continental Congress, immediately after the Revolution, first by the voice of Rufus King, and then by the voice of Nathan Dane, insisted upon the Prohibition of Slavery in the Territories. Vote so as to vindicate those sentiments and principles of the County of Worcester, “heart of the Commonwealth,” always so constantly and honorably maintained. Vote so as to vindicate the Antislavery cause in its necessity, practicability, and dignity, and so as to confound its enemies, now banding together against it, under the lead of Mr. Thayer. Vote so as to vindicate the existence of the Republican party, which, if the theory of Mr. Thayer be true, should at once be disbanded. Vote, finally, so as to settle peacefully this great question, by taking it away from the chance and peril of conflict, and committing it to the calm judgment of Congress. It is vain to say that Slavery cannot exist in the Territories under the Constitution, and therefore legislation is superfluous. It is there in fact, and that is enough. It must be struck at once by Congress. St. Patrick banished snakes from Ireland; but that is no reason why the woman should not bruise the head of one found there. It is vain to say, as has been said, that the slaves are few,--amounting to fourteen only in New Mexico; for human rights, whether in a vast multitude or a solitary individual, are entitled to equal and unhesitating support. In this spirit the ancient lawgiver nobly declared that to be the best government “where an injury to a single citizen is resented as an injury to the whole state.” It is vain to say that the prohibition by Congress is superfluous in the present state of opinion; for nothing is clearer than the remark of Lafayette, that principles strong in themselves take new force, when solemnly recognized by all in the form of law. It is vain to say that Freedom is more powerful than Slavery, and therefore may be safely left face to face with its antagonist. In the progress of civilization, law has superseded the ordeal by battle; and law must now supersede this conflict. It is vain to say that the Territories are protected in any form, whether by the Constitution, public opinion, or the inherent strength of Freedom. No possible safeguard should be abandoned. Let there be double locks, double bolts, and double gates. No lock, no bolt, and no gate should be neglected by which Slavery may be fastened out. And, lastly, if Popular Sovereignty is invoked, let it be the Popular Sovereignty of the American people,
