But only once let them get snugly fixed in their fat offices, and we shall then hear nothing more about Southern slavery from them, for the very good reason, that they care nothing about it. They have tried various expedients, and fallen upon various plans, in order to accomplish their diabolical purposes, but they have made the discovery, that either the whig, or the democratic party must be dissolved--annihilated; before they can possibly succeed. They base this conclusion on the supposition, that the fragments of the demolished party will unite with them. Well, one of the two great parties must be dissolved; but the democratic party being strong, and well organized, it was vain for them to expect aid from that quarter; but, it was otherwise with the whig party; and from this source they had reason to hope for aid. Hence, they labored hard in the recent presidential canvass, to defeat the whig nominee; believing that it was at least probable, that if General Scott was defeated, the whig party would in that event dissolve, and a large majority of the voters belonging to that party would fall into their ranks. If the whig party should hang together, and God grant they may, if for no other reason, to avert a calamity so awful, then are they again destined to meet with defeat and discomfiture, as heretofore. It is true that the whig party may not have entire confidence in their rivals, the democratic party; they may doubt the propriety of some of the measures advocated by them--the purity of the motives of some of their leaders. They may raise many objections to the democratic party, but I assure you, my whig friends, that there is more patriotism in Col. Benton's or Gen. Cass's little finger, as well as some others of the same party, whom I could name, than there is in every abolition politician on this continent. If you must leave your own party, I pray you go over to the democratic ranks, or else, stand neutral; but for God's sake, and for the sake of our common country, never be found in the abolition ranks. Keep clear of them--stand aloof--come not near them--have nothing to do with them. I am not advising the whig party to disband; on the contrary, I believe that the interests of the country will be subserved by their hanging together as a band of brothers. It is only on the supposition, that you must and will bolt, that I give you this advice.
