The nearest approach to the point of declaring the power of a State over slavery is made by Judge Nelson. He approaches it more than once, using the precise idea, and almost the language too, of the Nebraska Act. On one occasion his exact language is, "Except in cases where the power is restrained by the Constitution of the United States, the law of the State is supreme over the subject of slavery within its jurisdiction."

In what cases the power of the State is so restrained by the United States Constitution is left an open question, precisely as the same question, as to the restraint on the power of the Territories, was left open in the Nebraska Act. Put that and that together, and we have another nice little niche, which we may ere long see filled with another Supreme Court decision, declaring that the Constitution of the United States does not permit a State to exclude slavery from its limits. And this may especially be expected if the doctrine of "care not whether slavery be voted down or voted up" shall gain upon the public mind sufficiently to give promise that such a decision can be maintained when made.

Such a decision is all that slavery now lacks of being alike lawful in all the States. Welcome or unwelcome, such decision is probably coming, and will soon be upon us, unless the power of the present political dynasty shall be met and overthrown. We shall lie down pleasantly dreaming that the people of Missouri are on the verge of making their State free; and we shall awake to the reality, instead, that the Supreme Court has made Illinois a Slave State.

To meet and overthrow the power of that dynasty is the work now before all those who would prevent that consummation. That is what we have to do. But how can we best do it?

There are those who denounce us openly to their own friends, and yet whisper softly, that Senator Douglas is the aptest instrument there is with which to effect that object. They do not tell us, nor has he told us, that he wishes any such object to be effected. They wish us to infer all, from the facts that he now has a little quarrel with the present head of the dynasty; and that he has regularly voted with us, on a single point, upon which he and we have never differed.

They remind us that he is a very great man, and that the largest of us are very small ones. Let this be granted. But "a living dog is better than a dead lion." Judge Douglas, if not a dead lion for this work, is at least a caged and toothless one. How can he oppose the advances of slavery? He don't care any thing about it. His avowed mission is impressing the "public heart" to care nothing about it.

A leading Douglas Democrat newspaper thinks Douglas's superior talent will be needed to resist the revival of the African slave-trade. Does Douglas believe an effort to revive that trade is approaching? He has not said so. Does he really think so? But, if it is, how can he resist it? For years he has labored to prove it a sacred right of white men to take negro slaves into the new Territories. Can he possibly show that it is less a sacred right to buy them where they can be bought cheapest? And unquestionably they can be bought cheaper in Africa than in Virginia.

He has done all in his power to reduce the whole question of slavery to one of a mere right of property; and as such, how can he oppose the foreign slave-trade,—how can he refuse that trade in that "property" shall be "perfectly free,"—unless he does it as a protection to the home production? And, as the home producers will probably not ask the protection, he will be wholly without a ground of opposition.

Senator Douglas holds, we know, that a man may rightfully be wiser to-day than he was yesterday; that he may rightfully change when he finds himself wrong. But can we for that reason run ahead, and infer that he will make any particular change, of which he himself has given no intimation? Can we safely base our action upon any such vague inferences?

Now, as ever, I wish not to misrepresent Judge Douglas's position, question his motives, or do aught that can be personally offensive to him. Whenever, if ever, he and we can come together on principle, so that our great cause may have assistance from his great ability, I hope to have interposed no adventitious obstacle.
