abolition party, and if abolitionism is to be engrafted on the Whig creed, from that moment I renounce the party, and cease to be a Whig. I go yet a step further: if I am alive, I will give my humble support for the Presidency to that man, to whatever party he may belong, who is uncontaminated by fanaticism, rather than to one who, crying out all the time and aloud that he is a Whig, maintains doctrines utterly subversive of the Constitution and the Union." Mr. Clay said that the events of the last few months had thrown together men of opposite parties, and he could say with truth and pleasure that during the late session he was in conference quite as often, if not oftener, with Democrats than Whigs; and he "found in the Democratic party quite as much patriotism, devotion to the Union, honor, and probity as in the other party." Gen. JAMES HAMILTON has recently addressed a somewhat remarkable letter to the people of South Carolina upon the state of public affairs and the course which he desires his own State to pursue. Gen. H. was the Governor of South Carolina during the nullification crisis, and is fully imbued with the spirit of resistance to the Union. But he is also a man of great practical sagacity, and after carefully surveying the whole field, he is convinced that action now on the part of South Carolina would be ruinous to her cause. He has been all through the Southern States, and says he is satisfied that, in the event of such action, there is not another Southern State that would join her in it. He sketches the state of feeling in each of the States he has visited, and represents the Union party as decidedly in the ascendant in every one of them. He proceeds to say that although some of the recent measures of Congress, and particularly the admission of California, were exceedingly unjust to the South, yet they afford no justification for a disruption of the confederacy. Many, he says, believe that in the event of secession a collision will arise with the Federal Government, and South Carolina would have the sympathy and the aid of the other Southern States. But he does not believe the Federal Government would bring on any such collision; he thinks they would only prevent goods from entering their ports, carry the mail directly past them, and transfer all the commerce which they now enjoy to Savannah. He thinks South Carolina should await the result of the great battle in the North, between those who stand up for the rights of the South and their opponents. If the latter prevail and elect their President two years hence, the fugitive slave law will be repealed, slavery will be abolished in the District of Columbia, and a crisis will then occur which will inevitably unite the South. He urges them to await this event. The letter is written with great energy and eloquence, and will have a wide and marked influence upon public sentiment.
