Party Giving Way--the People Coming Up

From the Cleveland True Democrat. On the 3d instant, a Wilmot Proviso meeting was held in Sandusky city, without regard to party. A committee, consisting of A. W. Hendry, M. Farwell, W. S. Mills, R. J. Jennings, representing all the different political parties, was appointed to prepare resolutions; and, in their absence, the meeting was addressed by S. F. Taylor, of Milan, and E. M. Stone, of Norwalk. The following, among other resolutions, were adopted: 1. Resolved, That the principle of keeping free soil free, is one that should receive the support of every man in the free States, without regard to party - it being above and beyond all party considerations. The slaveholders of the South always unite, regardless of party, upon this question; and the only course left for us is tamely to submit to their dictation, or adopt a course similar to theirs. - This latter should now be done by the People of the North, with reference to the extension of slavery - done with calmness and deliberation, but with firmness and decision. 2. Resolved, That we permit no party trammels to prevent the free and full expression of opinion, on the subject of the extension of slavery over territory now ours; and that, as free sons of a free soil and a free Government, we make the cause our own, and in the majesty and strength of justice, of truth, and right, proclaim to the world our unalterable opposition to extending the blighting curse of slavery over one foot of soil now free. 3. Resolved, That while the North have acknowledged the evil, and done it away, the South have grasped it with a giant's hand, tho' slavery was an evil, a curse, a blighting curse. Though years of experience have taught the same lessons, and developed all the pernicious consequences of the system, yet, in the face of what tho North have done, disregarding the admonitions of her own great men, and refusing to profit by the pernicious consequences of a system fraught with vice and unnumbered evils to society, it is now asked of a civilized, enlightened, and Christian nation, to extend the institution of slavery over territory now free. 4. Resolved, That, upon the subject of the Wilmot Proviso, the North will, ere long, hold but one opinion; and we now declare it the sentiment of every man north of Mason and Dixon's line, unbought by party influence or unprejudiced by party zeal; and, upon this subject of national interest, the chains of party have been broken; the fettered partisan, loosed from his chains, has lisped the accents of "free territory - now and forever." A correspondent of the Boston Whig, thus writes: "Southern Whigs have, since the commencement of the war, opposed it on the ground that an acquisition of territory would tend to separate the North and South, politically. They have told their constituents so upon the stump. And now, since this territory has been thrust upon us, they will be greatly disappointed if Northern Whigs do not make the extension of slavery the great and only issue in the approaching canvass, To give you the feeling here, among some of their most able representatives: In conversation with a member from Virginia, since the ratification of the Treaty, I asked hirn what effect it would have upon the Whig party, North and South, He thought that the adoption of Wilmot Proviso, as the great issue, was inevitable; and he would not hesitate to take sides with the North, although the majority of his Southern Whig friends might, in such a position, be arrayed against him. "This gentleman is a slaveholder, but he openly declares that the system is a curse to the South. He says that any man can take his slaves, if he can be assured that they will be provided for. That he is right in his views, in regard to both the Proviso and the institution of slavery, no one will doubt, who has had an eye upon passing events and public sentiment, for the last two years."
