its treasury, its patronage, would all be turned, in harmony with the Constitution, to promote Freedom. The Committees of Congress, where Slavery now rules,--Congress itself, and the Cabinet also,--would all be organized for Freedom. The hypocritical disguise or renunciation of Antislavery sentiment would cease to be necessary for the sake of political preferment; and the Slaveholding Oligarchy, banished from the National Government, and despoiled of ill-gotten political consequence, without ability to punish or reward, would cease to be feared, either at the North or the South, until at last the citizens of the Slave States, where a large portion have no interest in Slavery, would demand Emancipation, and the great work would commence. Such is the obvious course of things. To the overthrow of the Slave Power we are summoned by a double call, one political and the other philanthropic,--first, to remove an oppressive tyranny from the National Government, and, secondly, to open the gates of Emancipation in the Slave States. [_Loud applause._] While keeping this great purpose in view, we must not forget details. The existence of Slavery anywhere within the national jurisdiction, in the Territories, in the District of Columbia, or on the high seas beneath the national flag, is an unconstitutional usurpation, which must be opposed. The Fugitive Slave Bill, monstrous in cruelty, as in unconstitutionality, is a usurpation, which must be opposed. The admission of new Slave States, from whatsoever quarter, from Texas or Cuba [_applause_], Utah or New Mexico, must be opposed. And to every scheme of Slavery, whether in Cuba or Mexico, on the high seas in opening the slave-trade, in the West Indies, or in the Valley of the Amazon, whether accomplished or merely plotted, whether pending or in prospect, we must send forth an EVERLASTING NO! [_Long continued applause._] Such is the present, immediate duty of Massachusetts, without compromise or hesitation.
