With that force which usually enters into his addresses--with even more than his usual eloquence--the Senator referred to the scene which awaited him upon his return to Chicago, when, as represented, he met an infuriated mob, who assailed him for having maintained the measures of 1850--those compromises which, in the Northern section, it was urged had been passed in the interest of the South. But, pray, what one of those measures was it which excited the mob so described? Only one, I believe, was put in issue at the North--the fugitive slave law; that one he did not vote for. But it was the part of manliness to say that, though absent and not voting for it, he approved of it. Such, I believe, was his commendable course on that occasion. I give him, therefore, all due credit for not escaping from a responsibility to which they might not have held him. Are we to give perpetual thanks to any one because he did not yield to so senseless a clamor, but conceded to us that small measure of constitutional right--because he has complied with a requirement so plain that my regret is that it ever required congressional intervention to enforce it? It belonged to the honor of the States to execute that clause of the Constitution. They should have executed it without congressional intervention; congressional action should only have been useful to give that uniformity of proceeding which State action could not have secured. Concurring in the depicted evil of the destruction of the Democratic organization, it must be admitted that such consequence is the inevitable result of a radical difference of principle. The Senator laments the disease, but instead of healing, aggravates it. While pleading the evils of the disruption of the party, it is quite apparent that, in his mind, there is another still greater calamity; for, through all his arraignment of others, all his self-laudation, all his complaints of persecution, like an air through its variations, appears and re-appears the action of the Charleston Convention. That seemed to be the beginning and the end of his solicitude. The oft-told tale of his removal from the chairmanship of the Committee on Territories had to be renewed and connected with that convention, and even assumed as the basis on which his strength was founded in that convention. I think the Senator did himself injustice. I think his long Career and distinguished labors, his admitted capacity for good hereafter, constitute a better reason for the support which he received, than the fact that his associates in the Senate had not chosen to put him in a particular position in the organization of this body. It is enough that that fact did not divert support from him; and I am aware of none of his associates here who have forced it upon public attention with a view to affect him.
