Read it through once

But unfortunately for us, ambitious demagogues have seized upon the subject of slavery, and are convulsing the country from one end to the other. Slavery is the demagogue's hobby, and he mounts it, raises his hat, kicks and spurs, as if the salvation of the universe was suspended on his elevation, to some petty, insignificant office. Slavery is to us, as a great subterraneous fire, which is ever ready to burst upon us with volcanic violence, deluging our country with boiling lava, red hot stones, smoke and flames; carrying devastation, death and destruction in its train. But the subject will be agitated, more or less, and unless the people of this country become better informed on this subject, and peaceably adopt some practicable means for its final extirpation; sooner or later the Union will be endangered thereby. The North should cease to vex the South, and the South should cease to vex the North, and patriotic men North and South, should devise some means, by which the end might be accomplished at some future day. The question now presents itself to every friend of humanity--to every philanthropist; is there no remedy for these evils, or must we groan under their pestilential influence forever?
