The late elections having demonstrated that the Opposition of the North are abundantly able to elect a President, we may as well prepare for a stormy session of Congress and a prodigious foaming of slaveholders. To be sure, the people of the country are pretty well used to the raw-head-and-bloody-bone tactics of these gentlemen, but we shall be surprised if they do not outdo all they have ever done in this line, between now and next November.

A specimen card, a sample of cargo has, to be sure, been on the bulletin board since the advent of John Brown, and by his small specimen we can measure the great things to come.

But the spasm of detraction has been brief. The engineers of falsehood and alarm did the best they could in the space of time which they had to work in.

They gather round their standard in such numbers as to put to flight every suspicion that either calumny or threats can drive them from their convictions or their post, either now or hereafter.
