It is UNCONSTITUTIONAL!--The refutation is a part of our history, and is written in the pages of our statute book. It is OPPRESSIVE! It would exclude the southern states from sharing in the benefits of these new settlements. Are not the lands open to all, and disposed of at public sale? They can only be made valuable, it is true, by incessant labour, under severe privations. But this the hardy yeomanry of the eastern and middle states are willing to endure for the sake of independence and an establishment for their families. We see them accordingly in the van of our empire, subduing the forest and filling the wilderness with the busy sounds of industry and contentment. Are the slave holders of the south a privileged order, that these labours would demean them? Are they oppressed by being placed on an equality with their brethren of the north, who leave behind them all the artificial distinctions and luxurious indulgences of society? Are not their arms and limbs as capable of labour, and their bodies of fatigue? Where then is the inequality and the oppression? A citizen of a slave holding state, at home, and under his state laws, may be a petty monarch; and he is apt to fancy that he derives the power from an inherent birth-right. But out of his state, and from under its laws, he is an individual unit, a mere citizen of the United States; and can claim no privilege which is not granted to every American, or which is opposed to the spirit and intent of the constitution. That constitution pays no respect to persons. It does not recognise the existence of slavery; and the petition to admit it in the new states, is a glaring mockery of its character. It has been contended, that after the state was organized, the inhabitants might assemble in convention, and alter the constitution in this respect. Such an assertion betrays the grossest ignorance of the true principles of the Union. Our government is emphatically a _compact_, originally between the people; and since then, between Congress as their representative, and the new members. It is binding on both sides, and the terms of admission are, that Congress approves of the constitution which the state has formed. Its power of rejection, it is true, is limited to certain points. But upon those points that power is absolute; and amongst them, without a shadow of doubt, is _slavery._ The state which, having accepted of a limitation to its power in this respect, should presume to alter it, would set that power at defiance.
