"He was glad that the portion of the amendment which referred to the Missouri compromise had been struck out. He was not a member of Congress when that compromise was made, but it is due to candor to state that his impressions were in its favor; but it is equally due to it to say that, with his present experience and knowledge of the spirit which then, for the first time, began to disclose itself, he had entirely changed his opinion. He now believed that it was a dangerous measure, and that it has done much to rouse into action the present spirit. Had it then been met with uncompromising opposition, such as a then distinguished and sagacious member from Virginia [Mr. RANDOLPH], now no more, opposed to it, abolition might have been crushed for ever in its birth. He then thought of Mr. Randolph as, he doubts not, many think of him now who have not fully looked into this subject, that he was too unyielding--too uncompromising--too impracticable; but he had been taught his error, and took pleasure in acknowledging it." This declaration is explicit. It is made in a spirit of candor, and as due to justice. It is a declaration spontaneously made, not an admission obtained on interrogatories. It shows that Mr. Calhoun was in favor of the compromise at the time it was adopted, and had since changed his opinions--"entirely changed" them, to use his own words--not on constitutional, but expedient grounds. He had changed upon experience, and upon seeing the dangerous effects of the measure. He had been taught his error, and took pleasure in acknowledging it. He blamed Mr. Randolph then for having been too uncompromising; but now thought him sagacious; and believed that if the measure had met with uncompromising opposition at the time, it would have crushed for ever the spirit of abolitionism. All these are reasons of expediency, derived from after-experience, and excludes the idea of any constitutional objection. The establishment of the Missouri compromise line was the highest possible exercise of legislative authority over the subject of slavery in a territory. It abolished it where it legally existed. It for ever forbid it where it had legally existed for one hundred years. Mr. Randolph was the great opponent of the compromise. He gave its friends all their trouble. It was then he applied the phrase, so annoying and destructive to its northern supporters--"dough face,"--a phrase which did them more harm than the best-reasoned speech. All the friends of the compromise blamed his impracticable opposition; and Mr. Calhoun, in joining in that blame, placed himself in the ranks of the cordial friends of the measure. This abolition and prohibition extended over an area large enough to make a dozen States; and of all this Mr. Calhoun had been in favor; and now had nothing but reasons of expediency, and they _ex post facto_, against it.
