He then proceeded to lay bare and closely analyze the history of all that had been done, during the four years preceding, to produce the prevailing condition of things touching human Slavery; describing it as resulting from that, "now almost complete legal combination-piece of machinery, so to speak--compounded of the Nebraska doctrine and the Dred Scott decision." After stating the several points of that decision, and that the doctrine of the "Sacred right of self-government" had been perverted by the Nebraska "Squatter Sovereignty," argument to mean that, "if any one man chose to enslave another, no third man shall be allowed to object," he proceeded to show the grounds upon which he charged "pre-concert" among the builders of that machinery. Said he: "The people were to be left perfectly free, 'subject only to the Constitution.' What the Constitution had to do with it, outsiders could not see. Plainly enough now, it was an exactly fitted niche for the Dred Scott decision to afterward come in and declare the perfect freedom of the people to be just no freedom at all. Why was the amendment, expressly declaring the right of the people, voted down? Plainly enough now, the adoption of it would have spoiled the niche for the Dred Scott decision. Why was the Court decision held up? Why even a Senator's individual opinion withheld, till after the Presidential election? Plainly enough now: the speaking out then would have damaged the 'perfectly free' argument upon which the election was to be carried. Why the outgoing President's felicitation on the indorsement? Why the delay of a re-argument? Why the incoming President's advance exhortation in favor of the decision? These things look like the cautious patting and petting of a spirited horse, preparatory to mounting him, when it is dreaded that he may give the rider a fall. And why the hasty after-indorsement of the decision, by the President and others? We cannot absolutely know that all these exact adaptations are the result of pre-concert. But when we see a lot of framed timbers, different portions of which we know have been gotten out at different times and places and by different workmen--Stephen, Franklin, Roger, and James--[Douglas, Pierce, Taney and Buchanan.]--for instance--and when we see these timbers joined together, and see they exactly make the frame of a house or a mill, all the tenons and mortices exactly fitting, and all the lengths and proportions of the different pieces exactly adapted to their respective places, and not a piece too many or too few--not omitting even the scaffolding, or, if a single piece be lacking, we see the place in the frame exactly fitted and prepared yet to bring such piece in--in such a case, we find it impossible not to believe that Stephen and Franklin and Roger and James all understood one another from the beginning, and all worked upon a common plan or draft drawn up before the first blow was struck."
